Chapter Text

The letter arrived on a Tuesday, sealed in black wax stamped with the triskelion.

Stiles knew what it was before his father broke the seal. He knew because he'd spent his entire life watching King John Stilinski open letters at this same desk, in this same study with its water-stained maps and its smell of ink and exhaustion, and he'd learned to read the language of his father's shoulders. When John's shoulders dropped, it was bad news from the border. When they squared, it was a challenge he intended to meet.

When they curved inward, folding around his chest like he was trying to hold his own ribs together — that was grief.

"Dad," Stiles said from the doorway.

John looked up. His eyes were red. "Come in. Close the door."

Stiles closed the door and crossed the study. He didn't sit. He stood on the other side of the desk and watched his father smooth the heavy parchment flat with hands that didn't quite shake.

"The Hales have made an offer," John said. "An alliance. Military support against the Argent Confederacy, open trade through the Preserve passage, a permanent seat for Beacon at the Hale war council."

Stiles felt the floor tilt slightly beneath him. Those terms were — that wasn't an alliance. That was salvation. The Argent Confederacy had been pressing Beacon's southern border for three years, and the kingdom was bleeding out slowly, a death of a thousand skirmishes and burnt crops and refugee columns winding north toward the capital. A seat at the Hale war council alone would have been worth nearly any price.

"What do they want?" Stiles asked.

John looked at him. Just looked at him, with that terrible curving of his shoulders, and Stiles understood.

"Me," Stiles said. "They want me."

"A marriage. To their Crown Prince. Derek."

Stiles barked a laugh that sounded wrong even to his own ears. "Of course. The only omega in the Stilinski line in three generations, and you thought — what? That I'd get to marry for love? That someone wouldn't eventually come to collect?"

"I have never thought of you as something to be collected."

"But you're going to say yes."

The silence was its own answer.

Stiles sat down. He sat down because his legs made the decision for him, folding like a chair with a broken joint, and he gripped the arms of the chair and stared at the triskelion seal on the parchment and thought: Derek Hale.

He thought about a ballroom. Candlelight. A boy with green eyes who'd stood at the edge of the crowd like he was made of different stuff than everyone else in the room, denser somehow, more real.

But that had been a long time ago.

"Tell me the terms," Stiles said.

The Gala (Six Years Earlier)

The Royal Concord Ball happened once every five years — a diplomatic tradition so old that no one could quite agree on which kingdom had started it. They took turns hosting. That year it was the Hales' turn, and the great hall of Triskelion Keep had been transformed into something out of a fever dream: living vines climbing the stone columns, bioluminescent flowers imported from the druid groves casting everything in shifting blue-green light, and enough food to feed Beacon's army for a week.

Stiles was sixteen and hated every minute of it.

Not the food. The food was incredible. He'd already stolen four of those little pastry things with the spiced meat inside and hidden two in his pockets for later. But the rest of it — the stiff formal clothes, the endless introductions to people who looked at him and immediately performed the social calculus of omega, prince, unmated, how useful — made him want to crawl out of his own skin.

He escaped to a balcony. Because of course there was a balcony, because the Hale keep was carved into the side of a mountain and every room seemed to open onto a sheer drop with a view of ancient forest rolling out toward the horizon like a dark green sea.

Someone was already there.

The boy was about Stiles's age, maybe a year older, leaning on the stone railing with his sleeves pushed up to his elbows in defiance of whatever formal dress code had produced the rest of the evening. Dark hair, strong jaw, pale eyes that caught the moonlight and refracted it back in a way that wasn't entirely human. Werewolf. And based on the quality of his clothes and the fact that he was brooding alone on a balcony at his own family's party — a Hale.

"Those pastry things are better if you eat them warm," the boy said without looking at him. "The ones in your pocket are going to be sad in about ten minutes."

Stiles looked down at his pocket, where a grease stain was slowly blooming on his formal coat. "I'm saving them for a strategic retreat."

"From what?"

"Lady Markham just tried to introduce me to her son. He's forty."

The boy's mouth twitched. Not a smile — a suppressed smile, which Stiles found more flattering. "Gregory Markham has a glass eye and a renowned collection of antique spoons."

"You're really selling it." Stiles came to lean on the railing beside him, keeping a careful distance, because he might have been sixteen but he already knew how to read the body language of someone who didn't want to be crowded. "I'm Stiles."

"I know who you are." Now the boy did look at him, and Stiles felt the eye contact like a physical thing, like someone had pressed a warm thumb to the center of his chest. "You're the Stilinski prince. The omega."

"And you're Derek Hale." Stiles saw the flicker of surprise. "I pay attention. Also, you have the triskelion embroidered on your collar and you're skulking at your own party, which narrows it down."

"I'm not skulking."

"You are absolutely skulking. World-class skulk. Grand tournament–level skulking." Stiles ate one of the pocket pastries out of spite. It was already lukewarm. "Why are you out here?"

Derek was quiet for a moment, and the silence wasn't uncomfortable — it was the kind of silence that happened when someone was deciding whether to give you the real answer or the polite one.

"I don't like the way people look at me in there," Derek said. "Like I'm — a position. A title. A set of advantages."

Stiles felt something shift in his chest. A small, tectonic rearrangement. Because that was — yes. That was exactly it.

"I know what you mean," he said.

Derek looked at him again. The moonlight did something to his eyes — made them look almost luminous, wolf-bright even in his human face. Stiles was suddenly very aware that he was standing close enough to catch Derek's scent, which was cedar and woodsmoke and something underneath that his omega hindbrain catalogued automatically and filed under oh no.

"You're not what I expected," Derek said.

"What did you expect?"

"Someone more... political."

"Give me time. I'm only sixteen. I'll be unbearable by twenty."

That got an actual laugh. Small, startled, like Derek's own amusement had caught him off guard. Stiles wanted to bottle it.

They talked for an hour. About nothing and everything — the geography of their respective kingdoms, the absurdity of formal dinners, a book about druidic history that they'd both read and had completely opposing interpretations of. Derek argued like he meant it, leaning in without realizing, and Stiles argued back with his hands and his whole body, and at some point the distance between them on the railing had disappeared entirely.

When Laura Hale came to find her brother — tall, dark-haired, with a smile that said she knew exactly what she'd interrupted — Stiles stepped back and felt the cool air rush into the space between them like water filling a trench.

"I should go," Stiles said.

"Yeah," Derek said. He was doing something complicated with his jaw, like he wanted to say more and was physically preventing himself.

Stiles waited. Derek didn't say it — whatever it was.

"It was nice to meet you, Stiles."

"Yeah," Stiles said. "You too, Derek."

He walked back into the gala and didn't look behind him, because he was sixteen and terrified of wanting something he knew he probably couldn't have. A prince from another kingdom, an alpha who'd looked at him like he was a person — it was a nice memory. That was all it could be.

He thought about it more than he should have, in the years that followed. Late at night, when the border reports were bad and the future felt like a hallway with all the doors locked, he'd think about moonlight on pale eyes and the sound of a startled laugh, and wonder if Derek Hale ever thought about him at all.

He never found out. And then the world caught fire, and Derek Hale disappeared.

The Road to Triskelion

The journey took twelve days.

Stiles rode in a carriage for the first three, staring out the window at the increasingly dense forest that marked the approach to Hale territory, and then abandoned the carriage on day four because the rocking was making him insane and he was going to lose his mind if he had to sit still any longer.

"You could ride in the carriage like a normal prince being escorted to his wedding," Scott said, pulling his horse alongside Stiles's.

"I could also stick my head in a beehive. Both options have about the same appeal."

Scott — Sir Scott McCall, technically, beta knight and Stiles's best friend since the age of four, the one person his father had allowed him to bring as part of his retinue without negotiation — looked at him with the particular expression he reserved for when Stiles was deflecting. It was a patient expression. Stiles hated it.

"You haven't talked about it," Scott said.

"About what? The weather? The scenic route? The fact that these trees are unnervingly tall?"

"About the fact that you're getting married in eight days to someone you've never met."

Stiles opened his mouth to correct him — to say actually, we met once, at a gala, and he laughed at my jokes and his eyes looked like sea glass in the moonlight, and I've thought about it roughly a thousand times since — but the correction felt too heavy to carry and too fragile to set down, so he closed his mouth again and just shrugged.

"What's to talk about? Dad needs the alliance. The Hales want an omega. I'm the omega. It's simple math."

"It's not math, Stiles, it's your life—"

"Same thing, in my case." He said it lightly. It didn't land lightly. Scott flinched, and Stiles felt guilty, and the guilt made him angry, and the anger had nowhere to go so he just kicked his horse forward and rode ahead of the column for a while, letting the wind scrub his face raw.

Lydia found him that evening, sitting by the fire while the rest of the retinue set up camp. She settled beside him with the particular grace of someone who'd been trained to make sitting on a log look like ascending a throne, and said nothing for a long time.

Lydia Martin was an omega noble from one of Beacon's oldest families, an emissary-in-training, and the most terrifyingly intelligent person Stiles had ever met. She'd volunteered for the retinue without being asked, and when Stiles had questioned why, she'd said, "Someone needs to make sure you don't do anything stupid, and the Hale library is reportedly the finest collection of magical texts on the continent," in a tone that made it clear both reasons were equally weighted.

"You're thinking so loud I can hear it from across camp," Lydia said.

"I'm wondering what he's like."

"There are reports. The Crown Prince was well-regarded before — before everything. Intelligent. Serious. Devoted to his family. Good with a sword."

"Great. I'm marrying a book report."

"You're marrying a political asset, and you're going to do it with your chin up, because that's who you are." She paused. "And then, once you're inside their keep, you're going to figure out what they're actually after, because these terms are too generous and the Hales don't give anything for free."

Stiles looked at her. The firelight caught the sharp planes of her face, the red-gold of her hair.

"You think something's wrong."

"I think a kingdom with the military strength of Triskelion doesn't need us. I think they want something specific, and they want it badly enough to overpay, and that makes me very, very curious."

She was right. Stiles had been thinking the same thing and hadn't wanted to look directly at it, the way you don't look directly at a sound in the dark.

"Guess I'll find out on my wedding night," he said.

Lydia didn't laugh. She put her hand over his, briefly, and the touch was warm and fierce and almost enough.

Triskelion Keep was not a castle. It was a statement.

It rose out of the mountainside as if the mountain itself had decided to grow architecture — dark stone, ancient and enormous, with towers that disappeared into the cloud line and roots that plunged into the bedrock. The forest pressed close on all sides, and as they rode through the final stretch of approach, Stiles could feel eyes on him from the tree line. Wolves. The Hale pack's outer guard, watching from the shadows of the Preserve.

The welcome was formal and correct. Queen Mother Talia Hale met them in the great courtyard — a tall woman with Derek's coloring and an alpha presence that Stiles felt like a change in atmospheric pressure, a heaviness in the air that made his omega instincts sit up and pay attention. She was beautiful and composed and her eyes were the saddest Stiles had ever seen.

"Prince Stiles," she said, taking his hands. Her grip was warm. "Welcome to Triskelion. We are grateful beyond words."

Grateful. Not pleased, not honored — grateful. The word choice landed in Stiles's mind and stuck there like a burr.

"Thank you, Your Majesty. I'm — honored to be here."

Laura Hale stood at her mother's side. Stiles remembered her from the gala — she'd been confident, laughing, magnetic. The woman in front of him now was thinner, with shadows under her eyes that spoke of long nights and longer worries. She looked at Stiles with an expression he couldn't parse: hope and guilt and something that might have been an apology.

"I'll show you to your rooms," Laura said. "You must be tired from the road."

"Where's Prince Derek?" Scott asked, because Scott's protective instincts had no respect for diplomatic niceties. "Shouldn't the groom be here to meet his—"

"Derek is... preparing," Talia said smoothly. "You'll meet him at the ceremony."

Scott opened his mouth again. Stiles stepped on his foot.

The rooms were beautiful. The rooms were a bribe. Stiles catalogued the details — the furs on the bed, the fire already burning, the window that overlooked the Preserve with its endless canopy — and noted how far they were from the main hall, how thick the walls were, how the servants who'd escorted them had disappeared immediately after, as if proximity to this wing of the keep was something to be minimized.

He was still cataloguing when someone knocked on his door that evening. Not Scott, who would have barged in. Not Lydia, who would have announced herself. A knock that was both polite and immovable, like a request that was actually a summons.

Stiles opened the door. Talia Hale stood in the corridor, alone. Without the formal audience, the sadness in her face was almost unbearable.

"May I come in?" she asked. "There are things I need to tell you before the ceremony. Things I should have told you before you came."

Stiles stepped aside.

Talia walked to the window and stood there for a moment, looking out at the darkening forest. When she turned back, she'd squared her shoulders — the gesture of someone bracing for impact from the inside.

"Derek is feral," she said.

The word dropped into the room like a stone into still water.

"He has been for twenty-two months. Since the fire. Since Kate Argent." She said the name like it tasted of ash. "He shifted during the attack — he saved us, he pulled three of his cousins out of the burning wing while the roof was coming down — and he never shifted back. He's been a wolf ever since. He doesn't speak. He doesn't recognize us. He is — he is my son, and he looks through me like I'm a stranger."

Stiles realized he'd stopped breathing and forced himself to start again.

"The marriage," he said. "The alliance. Those terms. You weren't buying a political partner. You were buying—"

"A chance." Talia's voice cracked on the word and then steadied, an act of will so visible it hurt to watch. "The oldest lore says that a true mate bond — consummated, sealed — can reach an alpha even in the depths of feral regression. His wolf would have to recognize you. Accept you. Choose you as mate. If it does, the bond could give him something to surface for. A reason to come back."

"And if it doesn't?"

"Then you'll be the consort of a kingdom with no functioning Crown Prince, bound to a wolf who may never be a man again. And the alliance will still hold. Your kingdom will still be safe. I swear it on my blood and my pack."

Stiles stared at her. He felt — he didn't know what he felt. The floor was tilting again, worse this time, and there was a roaring in his ears that might have been fury or might have been the sound of every assumption he'd made about this arrangement collapsing simultaneously.

"You let me ride for twelve days thinking I was coming to a normal political marriage."

"Yes."

"You let my father agree to this thinking—"

"Your father knows." The words were quiet. Devastating. "I told him everything. He wept, and then he said yes, because your kingdom is dying, Stiles. The Argents will be at your gates within the year if Triskelion doesn't intervene. He made the calculation that a father should never have to make, and he hated himself for it, and he said yes."

Stiles sat on the edge of the bed. He pressed his hands flat against his thighs and breathed and breathed and breathed.

His father had known. His father had known, and he'd held Stiles at the gate and kissed his forehead and said come home to me when you can, and Stiles had thought he meant visit but he'd actually meant if you survive.

"I want to see him," Stiles said. "Derek. Before the ceremony. I want to see what you're asking me to walk into."

Talia hesitated. For the first time, something like fear crossed her face.

"That's... not advisable. He's aggressive with strangers. He's injured—"

"I want to see him, or I walk out of this keep tonight and your alliance dies on the road back to Beacon. Your choice, Your Majesty."

The silence stretched. Then Talia nodded once, and Stiles followed her out of the room and into the depths of the keep.

They went down before they went up.

The tower was accessed through a passage that wound through the oldest part of the keep — stone corridors with no windows, lit by druidic runes that pulsed with a faint, sickly green light. Stiles counted three locked doors, two guard posts manned by betas who wouldn't meet his eyes, and one set of wards that made his teeth ache as they passed through. Whatever was at the end of this passage, the Hales had built a prison around it and called it care.

"He's in the upper chamber," Talia said. Her hand was on a final door — iron, reinforced, with claw marks gouged into the interior surface that Stiles could see through the observation slot. "The room is large. He has space. We've tried to make it — comfortable."

"Comfortable," Stiles repeated flatly.

"There are things you need to understand. Don't run. If he charges, stand your ground and bare your throat — it's a submission signal. Don't touch him unless he initiates. Don't—"

"Open the door."

Talia opened the door.

The room was large, as promised — a circular chamber at the top of the tower, with high windows that let in the moonlight and the mountain air. The floor was stone, scattered with torn bedding and what had probably been furniture before something had methodically destroyed it. The walls bore the evidence of claws and fury: deep gouges, cracked stone, one section where the mortar had been torn away entirely to expose the raw rock beneath.

And in the center of the room, lying on the wreckage of what had once been a bed — the wolf.

He was enormous. Stiles had seen werewolves in their shifted forms before, but Derek was something else entirely — easily the size of a small horse, pure black, with a musculature that spoke of an alpha in his prime even through the matting and neglect of his coat. His eyes were closed. He looked like he was sleeping.

Stiles stepped into the room. Behind him, he heard Talia make a small, involuntary sound, but the door didn't close. Escape route. Good.

He took another step.

The wolf's eyes opened.

Red. Alpha red, blazing in the dark like coals — not the controlled crimson that an alpha flashed in dominance displays, but a constant, burning scarlet that said the wolf was always there, always at the surface, always running. The intelligence in those eyes was animal, not human. Assessing. Calculating threat.

Derek rose. The movement was fluid and massive, a ripple of black fur and muscle that unfolded from the floor like a wave, and Stiles's hindbrain screamed run, run, run with a simplicity that was almost restful. His body went rigid. His heartbeat went thermonuclear. Every omega instinct he had fired simultaneously, a cocktail of fear-submission-appeasement that probably hit the air like a flare.

The wolf's nostrils flared.

Derek crossed the room in four strides, and Stiles didn't run. He didn't bare his throat, either, because fuck Talia's instructions — he wasn't going to grovel for an animal, not even one that used to be a prince. He stood his ground and fisted his hands at his sides and looked the wolf directly in its red, red eyes.

Derek stopped. Two feet away. Close enough that Stiles could feel the heat radiating off him, could smell the musk and wildness and underneath it, faintly — cedar and woodsmoke.

His heart lurched.

Oh, he thought. Oh, you're still in there.

The wolf lowered his massive head and inhaled. A long, deep breath, pulled from the air around Stiles's body like he was tasting him molecule by molecule. His nose tracked across Stiles's chest, his waist, his wrists — pausing at each pulse point where omega scent ran strongest. Stiles stood perfectly still and felt like he was being read.

Then Derek circled him.

Slow. Deliberate. A predator's circuit, nose working constantly, and Stiles turned with him because he was not going to let a feral alpha get behind him, no matter how this was supposed to work. They revolved around each other, two bodies in reluctant orbit, and somewhere in the third rotation Stiles realized that the wolf's hackles had lowered. The snarl he'd been bracing for hadn't come. The red eyes were still bright but the quality of the light had changed — less threat, more... focus. Intensity without aggression.

Derek pushed his nose into Stiles's hip, hard enough to stagger him, and Stiles caught himself on the wolf's shoulder. His hand sank into the thick black fur and he felt the body beneath it go taut, every muscle locking—

And then releasing. A full-body shudder that rolled through the wolf like a seizure, and Derek pressed into Stiles's hand instead of away from it, a movement so desperate and uncontrolled that it didn't look voluntary.

"Hey," Stiles whispered. "Hey, easy. I'm here."

The wolf made a sound. Not a growl, not a whine — something between the two, a broken vocalization that made Stiles's chest ache with a sympathy so sharp it felt like a wound. He let his fingers move through the matted fur, slow and careful, and Derek's massive body shuddered again and pressed closer, and closer, until the wolf was shoving his entire head against Stiles's stomach with a force that nearly knocked him over, breathing in, in, in like Stiles's scent was oxygen and he'd been drowning.

Talia made a sound from the doorway. Stiles looked up and saw that she was crying — silently, one hand pressed over her mouth, tears tracking down her face.

"He's never done that," she whispered. "With anyone. He's never—"

Stiles looked down at the enormous wolf pressed against him, shaking, breathing him in like a revelation. And he thought about a balcony and moonlight and a boy who'd said you're not what I expected with wonder in his voice, and he understood with sudden, terrible clarity that the universe had a vicious sense of humor.

"I'll do it," he said. His voice came out steady, which surprised him. "I'll stay. I'll try."

He didn't say for the alliance or for my kingdom.

He didn't know what he was doing it for. But his hand was in Derek's fur and the wolf was breathing like it had forgotten how, and Stiles thought: I can't leave you here. I don't know why, but I can't.

The ceremony was held at dawn in the Hale family's private grove — a circle of ancient oaks deep in the Preserve, wound with druidic wards so old the magic had become part of the wood itself. No guests. No court. Only the Hale inner circle, Stiles's small retinue, and Deaton, the Hale pack's druid emissary, who would perform the bonding.

Derek was not present. Could not be present. The wolf had been sedated — reluctantly, with great difficulty, three handlers sporting fresh claw wounds from the effort — and a proxy stood in his place: a portrait draped in the Hale colors, which Stiles found both absurd and heartbreaking.

"Is this legally binding?" Scott muttered from his position behind Stiles. He'd been vibrating with barely contained protective fury since Stiles had told him the truth the night before. His hand hadn't left the pommel of his sword.

"It's magically binding," Lydia murmured from Stiles's other side. Her eyes were on Deaton's preparations with the sharp focus of someone cataloguing every ingredient, every gesture, every word. "Which is what matters. The bond herbs will key to Stiles's biology and create a — a beacon, essentially. A scent signature amplified enough to reach even a feral alpha's recognition."

"That sounds like you're turning him into bait."

"Scott," Stiles said quietly. "Not now."

The ceremony itself was brief. Deaton spoke the words in the old tongue — a language that resonated in Stiles's bones rather than his ears — and anointed his wrists and throat with an oil that smelled of wolfsbane and juniper and something darker, older, that made his omega instincts prick up their ears. He felt the magic settle over him like a second skin: warm, tingling, slightly invasive, as if something was rearranging his scent from the inside out.

"The bonding herbs will destabilize your heat cycle," Deaton told him afterward, with the clinical detachment of someone explaining a weather forecast. "You may experience irregular surges of heat-adjacent symptoms. Heightened scent sensitivity, increased — ah — lubrication, emotional volatility. This is by design. The amplified omega pheromones are what will reach the alpha's—"

"Got it," Stiles said. "You've turned me into a walking aphrodisiac bomb. Great."

Deaton blinked. "That's... one way to phrase it."

"Is there a way to phrase it that doesn't make me feel like an alchemist's test subject?"

"The bond herbs are a gift," Talia said. She'd been standing at the edge of the grove, watching, and now she stepped forward. "They don't create attraction. They amplify what's already there. If the wolf didn't respond to your scent naturally, no amount of alchemy would change that."

Stiles thought about the tower. The wolf pressing against him. The desperate, shuddering breath.

"He responded," Stiles said.

Talia's eyes softened. "Yes. He did."

They brought him to the tower at sundown.

The chamber had been cleaned — the destroyed furniture removed, new bedding brought in, furs and cushions piled deep in a nest-like arrangement that Stiles recognized as an accommodation for wolf instincts. Candles burned in iron sconces too high for claws to reach. The windows had been opened to let in the evening air, and the sound of the forest filled the room: wind in the pines, the distant call of an owl, the vast breathing quiet of the Preserve.

Derek was already there. Awake, unshackled, standing in the center of the room with his hackles raised and his red eyes tracking Stiles's approach. The sedative had worn off, and whatever goodwill Stiles had earned the night before, the wolf didn't seem to remember it. He looked massive and dangerous and fundamentally alien, an intelligence behind those eyes that operated on rules Stiles didn't understand.

"Hi," Stiles said from the doorway. "It's me again. The omega who smells like your new favorite drug, apparently."

Derek's lip curled. A low rumble — not quite a growl, but its precursor — rolled through the room.

"Okay. Not in a joking mood. That's fair. Neither am I, if we're being honest."

Behind him, the door closed. The lock engaged. Stiles was alone with the wolf.

He didn't approach. Instead, he sat down against the wall by the door, drew his knees up to his chest, and started talking.

"So here's the deal. Your family sold my kingdom an alliance in exchange for me coming up here and — being your emotional support omega, I guess. Which is a hell of a thing to put on someone without their consent, by the way, and we're going to have a conversation about that, you and I, when you can have conversations again. If you can have conversations again." He paused. "I'm going to operate on the assumption that you can. That you're in there somewhere. Because I met you once, at a party, and you were — you were real. You were the first person who ever looked at me like I was more than my designation. And I don't think the person who did that is gone. I think he's just... buried."

Derek had stopped rumbling. His head was cocked, and his ears were forward — the posture of a canine processing an unfamiliar but interesting sound. Stiles's voice. He was listening to Stiles's voice.

"I'm going to stay here tonight. I'm not going to touch you unless you want me to. I'm not going to — do anything. I'm just going to be here. And you can decide what to do with that."

He leaned his head back against the stone wall and waited.

It took two hours.

Two hours of Stiles sitting against the wall, talking steadily about nothing — about the journey, about Scott's horse's bad attitude, about the way the Preserve smelled different from Beacon's forests, denser and older and more awake — while Derek circled the room in restless, overlapping orbits that gradually, incrementally, tightened.

When the wolf finally lay down, it was six feet away. Close enough for Stiles to see the rise and fall of his breathing but not close enough to touch.

"That's good," Stiles murmured. "That's fine. Whatever you're comfortable with."

He didn't sleep. He sat against the wall and watched the moon move across the window and listened to the wolf breathe, and in the gray light of early morning, he realized that Derek had moved closer in the night without waking him. Four feet. Three. The wolf's massive black head was resting on his outstretched paws, and his red eyes were half-lidded, and he was watching Stiles with an expression that — on a human face — Stiles would have called longing.

"Yeah," Stiles whispered. "I know."

The first week was education.

Stiles spent his days in the Hale library with Lydia, devouring every text on feral regression they could find — druidic treatises, Hale family histories, clinical accounts from pack healers across three centuries. The literature was thin. Feral regression was rare, poorly understood, and most accounts ended the same way: the alpha either recovered spontaneously within the first few months or didn't recover at all.

Twenty-two months was, by every historical measure, too long.

"There are four documented cases of recovery past the one-year mark," Lydia reported, cross-referencing three texts simultaneously in a way that made Stiles feel both awed and inadequate. "All four involved a mate bond. Two were pre-existing bonds that deepened through sustained proximity. Two were new bonds formed with the alpha in feral state."

"And?"

"The two new bonds took months. And both accounts describe the consummation as the turning point — not the beginning of recovery, but the catalyst. Everything before it was groundwork. Proximity. Scent habituation. Trust."

"Trust," Stiles repeated. "With an animal."

Lydia looked at him over the top of her book. "Derek isn't an animal, Stiles. He's a traumatized person trapped in a form that can't express trauma in human terms. The wolf is Derek — it's his most fundamental self, stripped of every human defense mechanism. If you can earn the wolf's trust, you've earned Derek's trust. At the deepest level possible."

She was right and Stiles knew it, and it made the whole thing harder, not easier.

Each evening, he returned to the tower.

He brought things. A blanket that smelled like himself, slept in and unwashed, which he left in the nest of bedding. Books, which he read aloud. Food — not the raw meat Derek's handlers provided, but human food, cooked meals, on the theory that scent memory might trigger something. The wolf ignored the food but seemed fascinated by the blanket, nosing at it for twenty minutes the first night and then dragging it to the center of the nest and lying on it with an air of possessive satisfaction.

"Congratulations," Stiles told him. "You've stolen my blanket. This is basically a relationship now."

The wolf made a chuff sound that might have been agreement.

Touch came gradually. Derek would approach, nose working, and press his muzzle against Stiles's wrists, his throat, the crook of his elbow — anywhere the scent glands lived. Stiles learned to hold still for this, to let the wolf investigate, to breathe through the rush of alpha, close, strong that his omega body produced in response. Derek's scent was overwhelming up close: the cedar and woodsmoke that Stiles remembered from the gala, amplified and roughened by the shift, layered with something richer and darker that made Stiles's hindbrain want to roll over and present.

He did not present. He sat still, and breathed, and let the wolf map him.

On the fourth night, Derek put his head in Stiles's lap.

It was abrupt, unselfconscious — the wolf had been circling in his usual pattern, spiraling closer, and then simply walked up and dropped his enormous skull onto Stiles's thighs as if it belonged there. The weight was staggering. Stiles's hands came up reflexively and sank into the fur at Derek's neck, and the sound the wolf made — a low, rumbling vibration that Stiles felt through his whole body — was so close to a purr that it made his eyes sting.

"There you go," Stiles whispered, scratching behind Derek's ears, feeling the tension drain out of the massive body one degree at a time. "There you go. I've got you."

On the fifth night, the licking started.

Stiles came through the tower door, still talking — he always came in talking, a continuous stream of narration that he'd learned the wolf oriented toward like a plant toward light — and Derek was there, up and alert, crossing the room before the door had fully closed. The wolf's massive head pushed into Stiles's stomach in the now-familiar greeting, and then — instead of the usual scent-cataloguing, the careful nose pressed to wrist and throat — Derek's tongue swiped a broad, wet stripe up the side of Stiles's face.

Stiles sputtered. "Oh — dude. That's — that is so much saliva."

The wolf did it again. Chin to temple, enthusiastic and thorough, and the sheer normalcy of it — a dog greeting its person, except the dog weighed as much as a pony and had teeth the length of Stiles's thumb — startled a laugh out of him. He wiped his face with his sleeve and Derek immediately licked the other side, and Stiles laughed harder, pushing at the wolf's muzzle with both hands.

"Okay, okay! I'm here! I'm home! You can stop — would you stop — "

But he was grinning, and the wolf's tail — which Stiles had never seen move before — gave a single, slow wag.

It became a ritual. Every evening when Stiles arrived: face, chin, sometimes an enthusiastic swipe across his ear that made him yelp. Stiles pretended to hate it. He did not hate it. He looked forward to it with an intensity that he refused to examine too closely, because the alternative was admitting that the highlight of his day was getting his face washed by a feral werewolf, and that was a confession he wasn't ready to make to anyone, least of all himself.

On the tenth night, Stiles woke up in the nest.

He'd fallen asleep reading — A Historie of the Hale Pack, Volume III, which was dry enough to function as a sedative — and when he opened his eyes, he was lying in the pile of furs and cushions with Derek curled around him. The wolf's body was a furnace, black fur pressed against Stiles's entire back, one massive paw draped over Stiles's hip in a hold that was unmistakably possessive. Stiles could feel Derek's heartbeat against his spine: slow, steady, calm.

The wolf was asleep. Deeply, peacefully asleep, in a way that Stiles suspected he hadn't been since the fire.

Stiles lay very still and felt the heat of Derek's body soak into him, and his omega chemistry responded with a treacherous, liquid warmth that pooled low in his belly. Mate, his instincts whispered. Safe, warm, alpha, mate. He bit his lip and breathed through it and didn't move, and when the wolf stirred at dawn and pulled away, Stiles pretended he'd been asleep the whole time.

On the twelfth night, everything shifted.

Stiles was lying in the nest on his back, arms above his head, in the oversized sleep shirt he'd taken to wearing in the tower because anything more structured felt like armor and the wolf responded better when Stiles was soft, relaxed, unguarded. Derek was beside him, doing the slow, methodical investigation that Stiles had come to think of as inventory — the wolf checking that Stiles was still Stiles, cataloguing every scent, confirming that his human hadn't changed in the hours they'd been apart.

The nose worked up Stiles's forearm to the crook of his elbow, then to his bicep, and then Derek shoved his muzzle into Stiles's armpit and huffed — a deep, satisfied inhale, the scent gland there apparently producing something the wolf found irresistible.

"That is disgusting," Stiles informed him. "I am disgusted. You are disgusting. We are both disgusting."

Derek huffed again and then licked, a broad swipe of tongue against the sensitive skin, and Stiles convulsed.

"Oh — oh my god, stop, that tickles, that tickles—"

He was laughing — breathless, helpless, squirming laughter, the kind that happened involuntarily when someone hit the exact wrong spot — and he shoved at Derek's head with both hands but the wolf was immovable, two hundred pounds of determination, and licked again, and Stiles dissolved into hiccupping hysterics, thrashing in the nest like a landed fish.

"Derek! Derek! I swear to god—"

The wolf pulled back. The red eyes were bright, and if Stiles didn't know better — if he wasn't already anthropomorphizing wildly, which he absolutely was — he'd have said the wolf looked amused.

"You think that's funny?" Stiles gasped, still catching his breath. "You think — are you playing with me right now?"

The tail wagged. Twice.

"Oh my god. You are. You're playing."

Derek's tongue lolled out. The wolf dropped his head and licked Stiles's chest through the thin sleep shirt — a long, slow stripe up his sternum, less playful now, more deliberate — and Stiles's laughter stuttered and caught.

Because the tongue had dragged across his nipple.

It was — it shouldn't have been anything. A wolf's tongue through fabric, incidental contact, purely accidental. But Stiles's body didn't process it as accidental. His body processed it as a hot, wet, broad pressure dragging across one of the most sensitive points on his chest, and his nipple hardened immediately, and his breath changed, and a flush swept up his throat that had nothing to do with laughter.

Derek's nose twitched.

The wolf went very still. The playful energy evaporated, replaced by that focused, intent attention that Stiles had learned to recognize — the wolf processing a new scent, categorizing it, deciding what to do with it. Derek's nostrils flared wide, pulling in the air around Stiles's body, and Stiles watched the wolf's eyes change: the red brightening, intensifying, the pupils dilating.

He can smell it, Stiles thought. He can smell that I—

Derek licked across his nipple again. Deliberately this time. Through the shirt, slow, pressing down, and Stiles made a sound that was not a laugh. It was small and sharp and involuntary, and his hips twitched, and the wolf's head dropped lower.

Down Stiles's chest. Across his stomach, where the sleep shirt had ridden up to expose a strip of skin, and the tongue on bare flesh was a shock of heat that made Stiles gasp. Lower. To the waistband of his sleep pants, where the wolf pressed his nose against the fabric and breathed, and the sound Derek made was not playful at all — it was that deep, focused rumble, the one that meant want.

Because Stiles was hard. He was hard and he hadn't meant to be and there was nothing he could do about it — the wolf's proximity, the alpha pheromones, the tongue on his nipple, all of it had conspired to produce a very obvious physical response that his thin sleep pants did exactly nothing to hide. The head of his cock was pushing against the fabric, and there was a damp spot forming at the tip, and Derek's nose was right there, pressed against it, inhaling.

"Derek—" Stiles's voice came out strangled. "That's — you don't have to—"

The wolf nosed his cock through the pants. A firm, deliberate press of muzzle against the length of him, and Stiles's hips jerked up involuntarily, and the sound he made was mortifying. Derek rumbled again — louder, more insistent — and then hooked his teeth into the waistband of Stiles's sleep pants and pulled.

The fabric tore. Not all the way — just enough to drag the waistband down his hips, exposing him, and then the wolf's nose was on his bare cock and Stiles's brain went white.

"Oh — oh fuck—"

Hot breath. The nudge of a wet nose against sensitive skin, investigating, cataloguing. And then — the tongue.

One long, broad lick from the base of his cock to the tip, collecting the precome that had gathered there, and the sound Derek made — that deep, guttural rumble of satisfaction — vibrated against Stiles's skin and nearly ended him on the spot. The wolf licked again, slower, tasting, and Stiles's hand flew to Derek's head. Not to push him away.

To hold him there.

"God," Stiles breathed. "God, okay, that's—"

The wolf worked him with patient, thorough attention — long strokes of that impossibly wide tongue that covered more of him in a single pass than a human mouth ever could have, wrapping around his cock with a dexterity that shouldn't have been possible, the texture rough-soft and hot and devastating. Stiles's hips rolled up to meet each stroke, his fingers tangled in Derek's fur, his rational mind putting up one last protest — this is a feral wolf, this is a feral wolf, you should not be enjoying this as much as you are — before his body overruled his brain completely and he sank into it.

"Don't stop," he whispered. "Please — Derek — don't—"

The wolf didn't stop. The licking grew more focused, more intent, and then Derek's nose pushed past his cock to the space behind it — to the source of the slick that Stiles's omega body had begun to produce, warm and involuntary, the biological response to alpha proximity and arousal. Derek found it and the sound he made — raw, guttural, shattered — was the sound of an animal encountering something it had been built to want.

The tongue swept through the slick and Stiles keened.

Different. This was different from the attention to his cock — deeper, more intimate, the broad tongue lapping at the most sensitive part of him with a hunger that felt ancient and absolute. The wolf pressed closer, shouldering Stiles's thighs apart, and Stiles let them fall open because he was past resistance, past thought, past anything except the liquid fire of the wolf's tongue and the climbing, spiraling pressure in his core.

He came with Derek's tongue pressed flat against him, a full-body shudder that tore a cry from his throat and left him boneless in the furs. The wolf licked him through it — through the aftershocks, through the oversensitivity, gentling but not stopping until Stiles was trembling and spent and making small, wrecked sounds into the crook of his own arm.

When Derek finally pulled back, Stiles lay there and breathed. His body was humming, wrung out, the kind of post-orgasm lassitude that felt like being poured into a new shape. He stared at the ceiling and thought: That just happened. That just happened and I wanted it and I'd do it again in a heartbeat and I'm going to have a moral crisis about this later but right now I just — that happened.

He turned his head. Derek was sitting beside him, red eyes bright, tongue working over his own muzzle — licking away the taste of Stiles, savoring it — and his body language had shifted into something Stiles hadn't seen before. Alert but not tense. Satisfied but not sated. Aroused, in a way that was impossible to miss, because—

Stiles's gaze dropped.

The wolf's cock was visible — flushed and tapered, extending from its sheath, slick with arousal and very, very present. It looked — different from a human alpha's. Longer, with a tapered head and a thickened base where the knot would form. Stiles stared at it and felt a complex rush of emotions — curiosity, apprehension, desire, the dissonance of finding something objectively alien also objectively hot — and before he could overthink it, he reached out.

"Hey," he said softly. "Fair's fair."

His fingers touched Derek's cock and the wolf's entire body went rigid.

A whine — high, sharp, surprised — and Derek's hips stuttered forward, pushing into Stiles's hand involuntarily. The cock was hot against his palm, slick, and when Stiles wrapped his fingers around the shaft and stroked experimentally, the wolf made a sound that Stiles felt in his teeth. A full-body rumble that built from Derek's chest and rolled through the air like distant thunder.

"Easy," Stiles murmured, stroking slowly, learning the shape and weight of him. "Easy. Let me—"

He found a rhythm. Slow, firm strokes from base to tip, avoiding the swelling knot at the base, his thumb tracing the ridge beneath the head. The wolf's hips moved in counterpoint — shallow, instinctive thrusts, chasing the pressure of Stiles's hand — and Derek's head dropped against Stiles's shoulder, the massive skull pressing into him, hot breath panting against his neck. The intimacy of it was staggering — this enormous, dangerous creature shaking apart under Stiles's hand, trusting him with something this vulnerable.

"I've got you," Stiles whispered. The same words he'd said when Derek first put his head in his lap. But meaning something different now. Meaning everything different now. "I've got you. Let go."

Derek came with a shudder that ran through his whole body — a hot pulse over Stiles's fingers, the wolf's mouth opening against his throat in a silent cry, the rumble peaking into something almost like a howl that never quite left his chest. Stiles stroked him through it, feeling the knot swell uselessly against his palm, and the wolf pressed and pressed and pressed against him like he was trying to climb inside Stiles's body, like proximity wasn't enough, like nothing would ever be close enough.

When it was over, Derek licked his face. Slow, gentle, thorough — chin to temple, the greeting ritual repurposed as gratitude, as tenderness, as the only language the wolf had. Stiles closed his eyes and let him.

So that's going to be a thing, he thought. And for the first time, the thought didn't come with a moral crisis attached. It came with something warmer. Simpler.

Good.

"I want you to leave."

Stiles looked up from his breakfast. Scott was standing in the doorway of the dining hall, in full armor, with a look on his face that meant he'd been rehearsing this speech for hours.

"Excuse me?"

"This is wrong, Stiles. What they're asking you to do — it's wrong. He can't consent. He's an animal right now, and they're expecting you to—"

"Sit down."

"—to mate with him, and that's not a sacrifice you should have to make for a political alliance, no matter how badly Beacon needs—"

"Scott. Sit. Down."

Scott sat. His jaw was tight, his scent radiating protective distress in waves that made the other diners — all Hale pack members — shift uncomfortably.

"You think I haven't thought about this?" Stiles's voice was low, controlled. "You think I go up to that tower every night without thinking about the ethics of what I'm doing? I lie awake and I turn it over and over and I ask myself all the questions you're about to ask me, and here's what I've come to."

He leaned forward.

"Derek's wolf chose me. In that first meeting, before I'd done anything, before the bonding herbs, before any of it — his wolf looked at me and decided I was safe. That instinct, that choice — that's him, Scott. The wolf isn't a separate entity. It's the truest part of him, the part that can't lie or perform or hide. And that part chose me."

"That doesn't mean—"

"It means more than you think it does. In their world, in werewolf bonding, the wolf's choice is consent. The deepest kind. And I — I'm choosing too. Nobody's forcing me to go up there. Nobody's forcing me to sit with him and talk to him and let him sleep next to me. I'm doing it because—"

He stopped. Because why? Because a boy on a balcony had laughed at his jokes? Because the universe owed him one good thing? Because the feeling of Derek's heartbeat against his spine was the first time he'd felt safe in years?

"Because he needs me," Stiles said simply. "And I think — I think maybe I need this too."

Scott stared at him for a long time. Then his shoulders dropped, not in defeat but in something more complicated — acceptance braided with worry, the particular surrender of a best friend who knows he can't win.

"If he hurts you," Scott said. "If he touches you in a way you don't want—"

"Then I'll leave. I promise."

"And if you can't leave? If you're — in the middle of—"

"Deaton gave me a wolfsbane capsule. Emergency measure. One crack and it'll knock him out for six hours." Stiles touched his pocket. "I don't intend to use it. But it's there."

Scott nodded slowly. He reached across the table and gripped Stiles's hand, hard.

"I'm staying," Scott said. "As long as you're here. I'm staying."

"I know," Stiles said. "I know you are."

The problem with Peter Hale was that he was helpful.

Not overtly helpful, not obviously helpful — helpful in the way that a current is helpful when you're swimming in the direction it wants you to go. He appeared at Stiles's elbow in the library, recommending texts. He offered context about Derek's childhood, his temperament, the trauma that had preceded the feral state. He was charming and solicitous and made Stiles feel welcome in a keep that otherwise treated him with the wary courtesy reserved for sacrificial offerings.

"He was different, before Kate," Peter said one afternoon, settling into the chair across from Stiles in the library with the ease of a man who owned every room he entered. "More open. He laughed. He had this — absurd habit of reading in the garden, and he'd fall asleep in the sun and wake up with a book on his face and leaves in his hair." A pause, expertly timed. "Laura has a painting of it somewhere."

"You miss him," Stiles said cautiously.

"Of course I miss him. He's my nephew."

"And your heir presumptive status would end if he recovered."

Peter's smile didn't change, but something behind his eyes went very still. "Ah. Lydia Martin's influence, I assume."

"My own observation, actually. Though Lydia did point out that you've consolidated quite a lot of power in twenty-two months for someone who's supposedly just keeping the seat warm."

"Someone had to govern, Stiles. Talia is consumed with Derek's recovery. Laura abdicated her succession rights. Someone had to ensure the kingdom didn't collapse while our alpha prince was busy being a wolf."

"And you've done that admirably. Which is exactly what concerns me."

Peter leaned forward. The charm didn't drop — it refined, became sharper, more targeted. "Let me be transparent with you, since you clearly value it. Yes, I benefit from Derek's condition. Yes, I am aware of that, and yes, others are aware of it, and it is a very uncomfortable position for a man who genuinely loves his nephew. I want Derek to recover. I also want you to understand that if he does recover, the power dynamics of this family change fundamentally, and there are people in this court who have built their positions on his absence."

"People like you?"

"People who are more dangerous than me." He stood, brushing invisible dust from his sleeve. "I'm not your enemy, Stiles. But I'm not your friend, either. I'm an interested party with complicated motivations, and the best thing I can do for you is be honest about that."

He left. Stiles stared after him and thought: That was either the most genuine thing anyone in this keep has said to me, or the most sophisticated manipulation. And I can't tell the difference.

Lydia could tell the difference, or at least she had theories.

"He's hedging," she said that evening, reviewing the day's research in Stiles's chambers. "If Derek recovers, Peter wants to be the uncle who helped. If Derek doesn't recover, Peter wants to be the regent who stepped up. He's positioned himself for both outcomes, which means he doesn't care which one happens."

"That's almost worse than if he were working against me."

"It is worse. An enemy is predictable. A pragmatist is a weather system."

Chapter Text

The bonding herbs hit on the sixteenth day.

Stiles had been warned. Deaton had explained the mechanism with his usual clinical precision — the herbs destabilized the omega heat cycle, causing irregular surges that could last hours or days, designed to produce the pheromone output that the mate bond required. Stiles had nodded and taken notes and assumed he could handle it.

He could not handle it.

He woke in the gray predawn in his own chambers — not the tower, not yet, he'd been sleeping separately during the days to maintain some fragment of normalcy — and his body was on fire. Not the gradual build of a natural heat, which he'd experienced twice a year since presentation and had learned to manage with suppressants and careful scheduling. This was a sudden, violent onset that hit him like a wave, a wall of sensation that rolled through his body and left him gasping, sweating, shaking, slick already soaking through his sleep clothes.

"Oh, fuck," he breathed into his pillow.

Everything was heightened. The sheets against his skin felt like electricity. His own scent was pouring off him in waves, thick and sweet and desperate, and the omega in him was screaming alpha, where, need, now with a single-mindedness that left no room for rational thought.

He pressed his face into the pillow and rode it out — the first wave, at least, the initial surge that crested and broke and left him trembling and hypersensitive, his body aching with a need so profound it felt architectural, as if his bones had been rearranged to make room for want.

When he could think again, he thought: The tower. Derek. I have to go to Derek.

Not because anyone told him to. Not because it was strategically necessary. Because his body knew, with a certainty that bypassed his brain entirely, that the answer to this need was in a room at the top of a tower, wrapped in black fur and burning with red eyes.

He made it to the tower on unsteady legs, wrapped in a robe that was already damp with sweat. The guards at the door took one look at him — one scent of him — and went pale. One of them was a beta and still had to step back, hand over his nose.

"Should I send for the emissary?" the guard asked.

"No. Open the door."

The door opened. The scent of alpha hit Stiles like a wall, and his knees buckled, and he caught himself on the doorframe with one hand and moaned — involuntary, mortifying, a sound that came from somewhere so deep in his body that it didn't feel like his voice at all.

Derek was already on his feet. The wolf's eyes were blazing, his nostrils flared wide, and the sound coming from his chest was a continuous low rumble that Stiles felt in his teeth. Not a growl. Something more ancient than a growl — a claiming sound, a mating call, a vibration that said mine, come here, mine.

Stiles took one step into the room. Then another. His body was moving without his permission, following the alpha scent like a compass following north. The heat surged again and he gasped, doubling over, slick running down his inner thighs, and the sound Derek made in response was devastating — a whine that broke through the rumble, high and desperate, the sound of an animal in pain.

"I know," Stiles panted. "I know, I — god — I know."

Derek crossed the distance between them in two strides. His nose drove into Stiles's throat, not gently — hard, urgent, inhaling like he was trying to breathe Stiles in — and then down, across his collarbones, his chest, his stomach, following the heat-scent that was pouring off Stiles's body like smoke. When the wolf reached his hip, his inner thigh, the place where the slick was concentrated and the scent was strongest, Derek made a sound that Stiles had no framework for — raw, guttural, shattered — and pressed his entire body against Stiles's legs.

Stiles's hands went to Derek's fur. He held on. He held on because his knees weren't working and his body was molten and the wolf was pressing against him with a need that mirrored his own so perfectly it felt like they were two halves of a circuit finally, finally connecting.

"Derek," he whispered. "Derek, I need — I think we need to—"

He couldn't finish the sentence. The heat took it, swallowed the words, replaced them with instinct. His robe fell. His knees hit the furs of the nest, and Derek was there, surrounding him, the heat of the wolf's body a furnace against his bare skin.

Stiles closed his eyes. He thought: I'm choosing this. I'm choosing this with my whole self, the rational part and the animal part and every contradictory thing in between. I'm choosing you.

He lowered himself onto his hands and knees.

The wolf didn't mount him.

Not yet. Not first. What Derek did first was what Derek had been doing since the twelfth night — what the wolf's instincts had been pulling toward since the first moment it caught the scent of Stiles's slick — and Stiles, on his hands and knees in the nest, naked and trembling and heat-drunk, felt the wolf's massive head push between his thighs from behind and thought, with a clarity that cut through the haze like glass: Oh. Right. This.

Derek's tongue found him.

Long — impossibly, inhumanly long, thick and rough-soft and searingly hot — it dragged a broad, flat stripe from Stiles's perineum to his tailbone, and Stiles's arms gave out immediately. He dropped to his elbows with a cry that cracked in the middle, face pressing into the furs, and his hips jerked back involuntarily, chasing the contact, because the sensation was — it was—

There was no framework for it. No human analogy. The wolf's tongue was wider and longer and more dexterous than anything Stiles had ever imagined, and it worked against him with a single-minded devotion that obliterated every rational thought he had left. Derek licked him like his slick was water in a desert — long, slow, savoring strokes that covered everything, that lapped at the source with a shameless, animal hunger that made Stiles want to die and come back and die again.

"Derek—" His voice didn't sound like his voice. It sounded ruined. "Oh my god, oh — fuck —"

The wolf rumbled. That deep, subsonic vibration of satisfaction, the one Stiles had first felt in the nest on the twelfth night, and now he felt it against him — the vibration traveling through Derek's tongue and jaw directly into the most sensitive part of his body. Stiles sobbed. Actual, genuine sobbing, not from pain but from a pleasure so intense it felt like being taken apart at the molecular level, each nerve ending lit up and singing.

Derek's tongue pushed inside him, and Stiles screamed into the furs.

Thick, hot, impossibly deep — the wolf's tongue flexed and curled inside him, lapping at the slick at its source, and Stiles's body responded with a fresh rush that he felt as a liquid pulse of heat, his omega biology interpreting the attention as alpha preparing, alpha claiming, give him everything. His thighs shook. His fingers clawed at the bedding. He could feel himself producing slick faster than Derek could drink it, his body in a feedback loop of stimulation and response that spiraled higher and tighter with every stroke.

The first orgasm blindsided him.

It came from nowhere and everywhere — a sudden, full-body seizure of pleasure that locked every muscle, that arched his back and ripped a sound out of him that wasn't a word or a moan but something more primal, something the omega in him recognized as surrender. He came untouched, his cock pulsing against nothing, spilling onto the furs while his inner muscles clenched and fluttered around the wolf's tongue, and Derek growled — a sound of triumph, of possessive satisfaction — and didn't stop. Didn't slow down. Kept licking through the orgasm with an intensity that crossed the line from pleasure into overstimulation and then, somehow, impossibly, circled back to pleasure again.

"I can't — Derek, I can't — it's too—"

But his hips were pressing back. His body was contradicting his mouth with a honesty that his brain couldn't override, rocking back against the wolf's muzzle, chasing the tongue, and some helpless part of Stiles thought: I'm going to let a feral werewolf eat me out until I lose consciousness and I don't care, I don't care, I actually do not care. And on the heels of that: Is this wrong? He's not — he can't — does this make me—

The thought splintered apart as Derek's tongue found a spot inside him that made his vision white out. The wolf licked it deliberately, rhythmically, with a focus that suggested even feral instinct understood the concept of there, that, do that again, and Stiles's ethical crisis dissolved into incoherent sound.

The second orgasm built slower, drawn out by the wolf's relentless attention into something agonizing and sweet. Stiles felt it gathering like a wave — the heat pooling low and deep, his thighs trembling, every muscle in his body taut as a wire. He was making sounds continuously now, a babbling stream of please and yes and Derek and profanity so creative it would have impressed him if he'd had any brain cells left to spare. The slick was everywhere — on his thighs, on the furs, on the wolf's muzzle — and Derek was drunk on it, the rumble in his chest so constant it was almost a purr, his red eyes half-lidded in something that looked, impossibly, like bliss.

When the second orgasm hit, it was deeper than the first — less sharp, more consuming, a rolling wave that crested and held him at the peak for an excruciating, beautiful eternity. He came with his face pressed into the furs and his voice gone to nothing but breath, and his body clenched around the wolf's tongue in pulses that he felt all the way to his fingertips.

Derek pulled back. Stiles whimpered at the loss — oversensitized, wrung out, every nerve ending screaming — and then the wolf licked a long, slow, possessive stripe up his spine, and the weight of him settled over Stiles's back, and the energy shifted.

Different now. Heavier. More urgent. The licking had been worship; this was claiming.

The wolf mounted him with a force that drove the air from his lungs.

Derek's weight was staggering — dense, furred muscle bearing down across Stiles's back, enormous paws landing on either side of his hips with a precision that spoke of instinct older than language. Stiles's arms shook. His breath came in harsh, shuddering gasps that fogged in the cool air of the tower, and his body — wrecked and oversensitized and still so ready, opened-up and slick-drenched from what the wolf had done to him — arched into the contact like it had been waiting for this its entire life.

The wolf's hips canted forward, seeking, and Stiles felt the blunt press of Derek's cock against his entrance. Larger than a human alpha's. Different. The head was tapered but the shaft thickened rapidly, and even through the haze, some distant, rational part of Stiles's mind threw up a flare of alarm—

And then Derek pushed in, and what was left of rational thought went quiet.

The stretch was enormous. Overwhelming. But after what the wolf's tongue had done to him — after two orgasms and the relentless, thorough attention that had left him open and aching and desperate to be filled — the burn melted almost immediately into a fullness so perfect it made Stiles gasp. His body took Derek in with a slick, yielding ease that felt like a lock finding its key, and the sound that came out of his mouth was nothing he recognized — guttural, grateful, wrecked.

"Oh god—" He dropped fully to the furs, every last pretense of holding himself up abandoned, and the angle changed and Derek's cock hit something inside him that the wolf's tongue had been teasing and Stiles's vision whited out. "Oh — oh, fuck, that's—"

The wolf's rhythm was instinctive, relentless — not rough, not exactly, but certain, each thrust a statement of claim that Stiles's body answered with slick and heat and a submission so complete it felt like falling. His cock hung heavy between his legs, untouched and aching, dripping onto the furs beneath him, and each drive of Derek's hips sent a shock of pleasure through him that built and built and built toward something enormous.

Derek's muzzle pressed against the back of Stiles's neck. Hot breath, the drag of teeth — not biting, not yet, but tasting, mouthing at the skin where a mating bite would go, and the anticipation of it, the knowledge that those jaws could crush bone, sent a bolt of adrenaline-drenched arousal through Stiles that made him sob.

"Do it," he gasped. "If you're going to — do it—"

The wolf drove deeper. The base of his cock was swelling — the knot, forming inexorably, stretching Stiles wider with each thrust until the push and pull of it against his rim was a sensation so intense it blurred the line between pleasure and pain. Stiles keened, fingers clawing at the furs, his whole body trembling, and Derek's forelegs tightened around his hips, pulling him back, locking them together as the knot expanded to its full size and caught.

Stiles came apart.

His third orgasm hit like a demolition — less sharp than the first two, deeper, more devastating, pulled from somewhere he didn't know he had left to give. A full-body convulsion that arched his spine and tore a scream from his throat. It went on and on, pulsing, his cock spurting weakly onto the furs — he was wrung out, emptied, but his body kept clenching and releasing around the knot in waves that felt like they'd never stop. Derek's knot throbbed inside him and the wolf's hips jerked in the shallow, rhythmic thrusts of his own release, flooding Stiles with a heat he could feel deep in his core.

And then the bite.

Derek's jaws closed on the junction of Stiles's neck and shoulder, and the pain was — incandescent. Brilliant. Like swallowing lightning, like every nerve in his body firing at once, and underneath the pain there was something else, something the texts had described but that no description could have prepared him for: the bond.

It snapped into place between them like a bridge being built in an instant. One moment Stiles was alone in his own head, and the next he was not — there was a presence, vast and raw, pressing against his consciousness from the other side. Wild. Confused. Grieving.

Oh, Stiles thought, and the tears that had been building spilled over. Oh, there you are.

Because underneath the animal panic, underneath the confusion and the instinct and the two years of wordless dark — there was a person. Fragmented, buried, but there. Stiles could feel him: a trapped, terrified intelligence that had been screaming into the void for twenty-two months and had just, for the first time, heard someone answer.

He felt Derek's grief. Not as a concept but as a physical sensation — a weight on his chest, a drowning pressure, the specific texture of guilt so profound it had eaten through every human defense mechanism and left nothing but the wolf. He felt the fire. He felt the betrayal. He felt a boy on a balcony, looking at an omega with brown eyes, thinking I want to know you, I want to know you and being too afraid to say it.

"I'm here," Stiles sobbed, the words muffled against the furs, the knot still locked inside him, the bond still blazing. "I'm here, Derek, I'm here—"

The wolf's jaws loosened on his neck. The tongue that swiped across the bite wound was gentle — achingly, impossibly gentle, cleaning the blood from his skin with a tenderness that didn't match the massive predator body still draped over him. Derek whined: soft, questioning, confused. The bond pulsed between them like a heartbeat.

Stiles reached back with one trembling hand and found Derek's fur, and held on.

They stayed locked together for nearly an hour. The knot pulsed in slow, rhythmic contractions that sent aftershocks of pleasure through Stiles's oversensitized body, and each pulse carried the bond deeper, wider, anchoring itself in both of them like roots growing into stone. Stiles drifted in a haze of endorphins and exhaustion and the overwhelming presence of Derek in his mind — not coherent, not verbal, but there, a constant warm pressure that felt like being held from the inside.

When the knot finally receded and Derek pulled free, Stiles collapsed onto the furs — or started to.

The wolf didn't let him. Before Stiles could roll over, before he could even process the sudden emptiness where the knot had been, Derek's muzzle was between his thighs again.

"Oh — oh god, Derek, I can't, I literally cannot—"

But the wolf wasn't trying to make him come again. This was different. Slower. Tender, in a way Stiles wouldn't have thought a feral animal capable of. Derek's tongue lapped at him in long, unhurried strokes — gentle now, none of the driving hunger from before — licking away the mess of slick and spend that was leaking out of him. Cleaning him.

Stiles shuddered. His body was so far past oversensitive that the touch registered as something beyond pleasure or pain — a deep, aching intimacy that felt more devastating than anything that had come before. The wolf was tasting both of them — his own release mixed with Stiles's slick — and the sound he was making, that low, satisfied rumble, said he liked it. That the mingled scent of them together was something the wolf wanted to savor, to memorize, to map with his tongue and file away as mine, mine, this is mine.

Stiles buried his face in the furs and let him. He was too wrecked to resist even if he'd wanted to, and he didn't want to, not even a little. Each careful stroke of the wolf's tongue felt like being claimed in the gentlest possible way — not the violence of the bite, not the overwhelming force of the knot, but a quiet, thorough declaration of ownership that his omega instincts recognized as aftercare.

He's taking care of me, Stiles thought, dazed. The feral wolf who can't remember how to be a person is taking care of me.

When Derek was satisfied — when he'd licked Stiles clean with a meticulousness that bordered on ritual — the wolf finally settled beside him, pressing his massive body against Stiles's back, and Stiles let himself go boneless.

He was wrecked — shaking, spent, the bite on his neck throbbing in time with his heartbeat. He felt hollowed out and filled up simultaneously, like his body had been taken apart and reassembled in a slightly different configuration.

The wolf lay down beside him. And then, slowly, carefully — as if the body didn't quite remember how — the wolf's shape began to blur.

Stiles watched, too exhausted to move, as the shift rippled through Derek's body in fits and starts. A paw elongating into fingers, then snapping back to a paw. A muzzle shortening, jaw restructuring, the black fur receding in patches to reveal pale skin beneath before the fur surged back. The wolf whined — in pain, in confusion, in the effort of a body trying to remember a form it had abandoned two years ago.

It didn't hold. The shift collapsed, and the wolf remained.

But for three seconds — three heart-stopping, breathless seconds — Stiles saw a man's face. Sharp cheekbones, dark stubble, brows drawn together in an expression of such profound confusion it looked like agony. And those eyes — green-gold, not red, human — blinking open and focusing, for one instant, on Stiles.

Then the wolf was back. The red eyes blinked, and the moment was gone.

But it had happened. The bond was working. The man was surfacing.

Stiles pressed his face into the wolf's neck and let himself cry — from relief, from exhaustion, from the overwhelming enormity of what had just passed between them. Derek's paw curled over his hip, claws retracting, and the wolf's breath was warm against his hair.

"Come back to me," Stiles whispered. "Take your time. But come back."

Recovery was not a straight line. It was a drunkard's walk, a river that doubled back on itself, a tide that advanced and retreated without pattern — moments of startling clarity separated by days of nothing, punctuated by setbacks that felt like falling off a cliff.

The morning after the consummation, Stiles woke alone. The nest was warm where Derek's body had been, and the wolf was standing at the window, staring out at the Preserve with an intensity that seemed less animal than before — more focused, more searching, as if he was looking at the forest and trying to remember something about it.

Stiles sat up. Every muscle in his body protested. The bite on his neck throbbed, and when he touched it, the bond flared — a pulse of awareness that he now understood was Derek, a wordless I know you're here that resonated in his chest.

"Good morning," Stiles said.

The wolf turned. Looked at him. And made a sound that was — new. Not a growl, not a whine, not any of the vocalizations Stiles had catalogued over the past week. A soft, rumbling chuff that he felt through the bond as warmth. Recognition. Mine.

"Yeah," Stiles said, his throat tight. "Yours."

He reported to Deaton that afternoon, submitting to the emissary's clinical examination with ill grace. Deaton inspected the bite mark, took scent samples, asked intrusive questions about the consummation that Stiles answered in monosyllables while staring at the ceiling.

"The bond has anchored," Deaton confirmed. "Strongly. Possibly the strongest initial anchoring I've seen in—"

"He almost shifted. Last night, after. For about three seconds, he was — there was a face."

Deaton went still. "He attempted a shift?"

"Not attempted. It happened. Involuntarily. He was a man for three seconds and then the wolf pulled him back."

"That's..." Deaton set down his instruments. For the first time in Stiles's experience, the druid looked genuinely affected. "That shouldn't be possible this early. The bond is days old. For it to trigger a partial shift already—"

"What does it mean?"

Deaton met his eyes. "It means the wolf recognizes you, Stiles. Not just as an omega, not just as a source of comfort. As mate. The recognition is strong enough to challenge the feral state directly. But twenty-two months of regression won't dissolve overnight. The wolf's hold is deep. Derek will need to fight his way back, and he'll need you to — to keep giving him reasons to."

"Reasons."

"The bond. Physical intimacy. Emotional connection. Your voice, your scent, your presence. Everything that makes you you, as distinct from a generic omega stimulus. He needs to want Stiles, not just a mate. The specificity is what will pull him through."

Stiles thought about this. About a boy on a balcony who'd said you're not what I expected, and wondered if the wolf remembered.

Over the days that followed, the fragments came.

Derek's shifts were unpredictable and always partial — a hand emerging from a paw, clawed and trembling, reaching for Stiles in the dark. A human torso fading into wolf haunches, the anatomy of a man who was two things at once and couldn't hold either. Sometimes Stiles would wake in the night to find Derek half-shifted beside him, a face that flickered between human and wolf like a signal struggling to lock, and he'd put his hands on whatever part was human and hold on.

"Stay," Stiles would whisper, fingers tracing a jaw that was stubbly one moment and furred the next. "Stay with me."

It never lasted. The wolf always pulled Derek back. But the fragments grew longer — three seconds became ten, became thirty, became two full minutes of a man lying in Stiles's arms, breathing hard, eyes green and terrified, before the shift reclaimed him.

And one night, eleven days after the consummation, Derek spoke.

It wasn't a word, exactly. It was a sound — a guttural, wrecked vocalization that pushed through a throat that hadn't formed human speech in nearly two years, and it came in the middle of the night, while Derek was half-shifted and pressed against Stiles's back, and it sounded like—

"Sss..."

Stiles's breath caught. "Derek?"

"Ssst..." The body behind him shuddered. Muscles clenched and released, the partial shift wavering, and the voice — rough as gravel, barely recognizable as speech — tried again. "Ssstiles."

Stiles rolled over. Derek's face was human. Fully, completely human — pale and drawn and sheened with sweat, dark hair plastered to his forehead, green eyes wild with the effort of maintaining the shift. His hands were still clawed, his shoulders still rippling with fur, but his face was a man's face, and it was looking at Stiles with an expression that shattered something fundamental in Stiles's chest.

"Hi," Stiles whispered.

"Stiles." Clearer this time. A rasp, but a word, with intention behind it. Derek's clawed hand came up and touched Stiles's face — so carefully, so tentatively, as if he was afraid Stiles might not be real. A claw traced down his cheek, not cutting, barely touching. "You're... here."

"I'm here."

"I can... hear you. In the — in the dark. Your voice. You never stop..." A shudder. The fur rippled across his shoulders. "...talking."

Stiles laughed. It came out wet. "Yeah, well, you should hear me when I'm really nervous."

"I remember." Derek's eyes were losing focus, the green flickering, red bleeding in at the edges. He was losing the shift. "The party. The balcony. You had — pastry in your pocket." A ghost of a smile, there and gone. "I wanted... to ask you to stay."

"I'm staying now," Stiles said fiercely. He put his hands on Derek's face, holding him, willing the shift to hold. "I'm right here and I'm not going anywhere."

But the wolf took him back. The green eyes flooded red, the jaw elongated, the stubble became fur, and the man dissolved into the animal, and Derek — the wolf — pressed his nose into Stiles's throat and breathed.

Stiles held him and didn't sleep for the rest of the night.

Word spread. Of course it did — this was a royal court, and secrets had the half-life of morning dew.

The whispers started small. The omega made the wolf shift. The omega is a true mate. The prince spoke. They spiraled outward through the keep like ripples in a pond, and in their wake came a shift in how the court treated Stiles: the wary courtesy transforming into something more complicated. Some people looked at him with hope. Some looked at him with resentment — the factions that had formed around Peter's regency, the courtiers who had built new power structures on the assumption that Derek was never coming back.

And some looked at him with calculation. Because if Derek recovered, the political landscape of Triskelion would change overnight, and everyone was positioning themselves for the earthquake.

Laura found Stiles on the battlements one afternoon, staring out at the Preserve. She looked better than she had when he'd arrived — the shadows under her eyes were still there, but something in her posture had loosened, as if a weight she'd been carrying had shifted to a more bearable angle.

"He said your name," she said. No preamble. "Mom told me. She cried for an hour."

"He said it once. For about ten seconds. Then the shift took him back."

"Stiles. He hasn't said anything in twenty-two months. He hasn't recognized anyone. Not mom, not me, not anyone who loved him his whole life. And he said your name." Her voice cracked. "Do you understand what that means?"

"It means your family's gamble paid off."

"It means my brother is still alive." She turned to him, and her eyes were bright. "I owe you — I owe you something I can't ever repay. You walked into that tower not knowing what you'd find, and you stayed. You stayed when you had every reason to run."

"I had reasons to stay too."

"The alliance."

"No." He hesitated. Then, because Laura had Derek's eyes and Derek's directness and he owed her the truth: "I met him once. At the Concord Ball, six years ago. We talked for an hour on a balcony and he — he looked at me like I was a person. Not an omega, not a prince, not a chess piece. A person. And I've thought about it every day since. So when they told me what had happened to him, when they told me he was trapped — I couldn't leave. Because that boy on the balcony deserved someone who'd fight for him."

Laura stared at him. Her mouth opened, then closed, then opened again.

"He told me about that night," she said softly. "After the gala. He said he'd met someone. He never told me your name, but he said — he said, 'I met someone who wasn't performing.' He talked about it for weeks, Stiles. He wanted to write to you. He was going to, and then... Paige happened, and Kate, and..."

She trailed off. They both knew what came next.

"He thought about you," Laura said. "I want you to know that. Whatever happens — he thought about you too."

Stiles looked out at the Preserve and blinked until the trees stopped blurring.

The second heat surge came three weeks into the bond, and it was worse.

Or better, depending on one's perspective.

The bond had deepened in the intervening days — a constant thrum of awareness that Stiles carried with him everywhere, Derek's presence a warm weight in the back of his mind. The fragments of humanity came more frequently now. Derek would shift partially during their nights together, spending longer and longer in his human or half-shifted form, though he couldn't hold it through the day. Stiles learned the geography of between: the way Derek's hands would shift human from the wrists down while his arms stayed furred, the way his face would flicker between forms when he was agitated, the way the green eyes would surface and then submerge like a swimmer struggling to stay above water.

He learned the sounds Derek could make. Not words — not yet, not again since that first time — but vocalizations that the bond translated into emotion. A low rumble when Stiles was close that meant comfort. A sharp whine when Stiles left the tower that meant don't go. A huffing exhale that meant something very close to laughter.

And the sound Derek made when Stiles's heat-scent hit the air: that deep, desperate, full-body vibration that meant want, need, mate, please.

The second heat hit at midnight. Stiles was already in the tower, already curled in the nest with Derek's wolf form pressed warm against his back, when the surge rolled through him — liquid fire from his core outward, his body going slick and hot and aching in the space between one heartbeat and the next. He gasped, arching, and behind him, Derek's wolf body went rigid.

The shift came fast this time. Faster than it ever had before — the wolf's body rippling, bones cracking and reshaping, fur receding in a wave. And then there were human arms around Stiles's waist, a human chest against his back, a human mouth against his neck, breathing in his heat-scent in desperate, shuddering pulls.

"Stiles—" Derek's voice, wrecked, barely there. "Stiles, I can't — I can feel you, I can feel—"

"I know." Stiles turned in Derek's arms. Derek was — mostly human. His eyes flickered between green and red, his hands were clawed, dark hair trailed along his forearms and across his shoulders like the wolf was lurking just beneath the skin. His body was lean and hard and warm, and he was hard against Stiles's thigh, and the sound Stiles made at the contact was not dignified.

"I don't — I don't know how long I can—" Derek's jaw clenched. The shift rippled across his face and he fought it back, a visible effort that corded the muscles of his neck. "The wolf. It's pulling me. I can feel it pulling."

"Then we don't have long." Stiles cupped Derek's face in both hands. Half-stubble, half-fur against his palms. Green eyes, desperate and present and so human it made his chest crack open. "Do you want this?"

"I have wanted you since I was seventeen years old," Derek rasped. "I have wanted you in every form I've worn. I want—" The shift surged. His jaw elongated, and he wrenched it back with a snarl, and when his face was his own again, his eyes were wet. "I want you to see me. Not the wolf. Me."

"I see you," Stiles said. "I've always seen you."

He kissed him.

Derek's mouth was hot and tasted of salt and something wild, and the kiss was clumsy — two years without human lips, without the muscle memory of tenderness — but it was real. Derek kissed him like he was drowning and Stiles was air, one clawed hand gripping the back of Stiles's neck, the other sliding down his body with a desperateness that wasn't entirely human. Stiles kissed back with everything he had, licking into Derek's mouth, swallowing the broken sounds Derek made, and the heat surged between them through the bond until Stiles couldn't tell whose arousal he was feeling.

Derek's mouth left his and traveled down — throat, chest, stomach — and Stiles recognized the trajectory with a full-body shiver, because the wolf had taught him this, the wolf had invented this between them, and here was the man following the same path with lips and teeth instead of a muzzle, but with the same desperate hunger. When Derek reached the crease of his thigh, he pressed his face against the slick-damp skin and breathed, and the sound he made — half-growl, half-groan — was the most human and the most animal sound Stiles had ever heard from him simultaneously.

"You don't have to—" Stiles started, and then Derek's tongue — still too long, still not entirely human, the shift lending it the wolf's impossible length and dexterity — licked a broad, devastating stripe through his slick and Stiles's sentence detonated into a moan.

It was different from the wolf. The same act, the same instinct, but filtered through a consciousness that was half-human and aware — Derek's clawed hands gripping Stiles's thighs and spreading him open, Derek's green-red eyes flickering up to watch Stiles's face as he licked into him, slow and deliberate, with an intentionality the wolf hadn't possessed. The wolf had been driven by instinct, by the compulsion to taste and consume. The man was driven by wanting to make Stiles feel this. And the hybrid tongue — thick and long and inhumanly agile — combined the worst of both: animal thoroughness with human precision.

Stiles came once like that, fast and sharp, his back bowing off the furs with a cry that rang off the stone, and Derek licked him through it and kept going — persistent, unrelenting, the wolf's appetite in a man's body — until Stiles was clawing at his shoulders and gasping "enough, enough, I need you inside me, Derek, please—"

Derek surged up over him, mouth wet, eyes blazing, and Stiles pulled him down into the nest. Stiles opened his legs and Derek settled between them, and the press of Derek's cock against him was — different from the first time. Human-shaped. Thick and hot and leaking, and when Derek pushed inside, Stiles arched off the furs and cried out, not in pain but in the overwhelming recognition of the bond snapping taut between them.

Derek dropped his forehead against Stiles's shoulder and groaned, and the sound carried twenty-two months of isolation and loss and the specific agony of a man trapped inside an animal who could feel but couldn't speak, couldn't hold, couldn't do this — couldn't move inside someone and feel them move back, couldn't hear his name in a voice that shook with want.

"Stiles — you feel — I can't—"

"Move," Stiles breathed. "Please, Derek, move—"

Derek moved. Long, deep strokes that bottomed out in a way that made Stiles see stars, that hit every sensitive place inside him with a precision that owed more to the bond than to technique — Derek could feel what Stiles felt, could follow the feedback loop of pleasure through their connection and adjust, angle, give exactly what Stiles needed. And Stiles clung to him and matched his rhythm and said his name, over and over, Derek, Derek, Derek, because names were power and language was human and every time Stiles said it, the green in Derek's eyes burned brighter.

"Don't stop," Stiles panted. "Don't — stay with me, don't shift, stay—"

"I'm trying—" Derek's thrusts grew harder, more urgent, and Stiles felt the knot begin to swell at the base of Derek's cock, felt it pressing against his rim with each stroke. Derek's face contorted — pleasure and the effort of holding his human form, fighting the wolf with everything he had. "I want to — I want to see your face when—"

The knot caught. Locked them together. And this time Stiles saw it — Derek's eyes blown wide, green and gold and human, his mouth open, his body shuddering through his release with a raw vulnerability that looked like the walls of a fortress coming down. Stiles came with him, between their bodies, untouched except where they were connected, and the bond blazed white-hot and he felt everything Derek felt: the pleasure and the relief and the grief and the love, the terrified, all-consuming love of a man who had thought he would never be himself again.

"I've got you," Stiles gasped, pulling Derek's head down against his neck, feeling the tears hot against his skin. "I've got you, I'm here, you're here, we're both here—"

The knot pulsed between them, binding them together, and Derek wept into Stiles's throat and Stiles held him and the bond hummed like a struck bell, resonant and clear and whole.

When the knot finally receded, Derek slid down Stiles's body — and Stiles recognized the trajectory instantly, his breath hitching.

"Derek, you don't — you don't have to—"

"I want to." Derek's voice was raw, barely above a whisper, and his eyes when he looked up from between Stiles's thighs were human and fierce and stripped of every defense. "The wolf — he needed to do this. And I — I want to. Let me."

Stiles let him.

It was unbearable. Not because of the overstimulation — though there was that, every nerve ending screaming — but because of the tenderness of it. Derek cleaning him with his mouth, slow and reverent, tasting their mingled spend with a low groan that vibrated against Stiles's skin. The wolf's compulsion made human, made conscious, made chosen. Derek's hands holding Stiles's thighs open, thumbs stroking soft circles against his skin, and his tongue — still half-shifted, still impossibly long — lapping him clean with a care that made Stiles's eyes burn.

It wasn't sexual, exactly. Or it was, but it was also something else — something that lived in the space between worship and caretaking, between the wolf's instinct to reclaim its mate's scent and a man's need to be gentle with the person he loved. Stiles lay in the furs and shook and let Derek have this, because he understood now that the cleaning was part of the claiming, that the wolf couldn't rest until its mate was tended to, and that Derek — human Derek, conscious Derek — wanted to be the one who did this. Wanted to be the hands and mouth that took care of Stiles when everything else was stripped away.

"Okay," Stiles whispered when Derek finally settled back over him, pressing his face into Stiles's neck. "Okay. That's — yeah. That's going to be a regular thing, isn't it."

"Yes," Derek said, without apology.

"Just checking."

The shift didn't take him back this time. Derek stayed human — shaking, exhausted, curled around Stiles in the nest — all through the night. When dawn came through the tower windows, Stiles opened his eyes and found Derek watching him.

Human eyes. Green. Clear. Present.

"Good morning," Stiles whispered.

Derek's mouth curved. Small, uncertain, like he'd forgotten how smiling worked.

"Morning," he said.

His voice was rough and unused and the most beautiful sound Stiles had ever heard.

The shift still took him sometimes.

Not as often. Not as completely. But there were mornings when Stiles woke to find the wolf beside him instead of the man, and the red eyes would blink at him with an apology in them that the wolf couldn't speak. Days when the trauma surged — a sound, a scent, a shadow that fell the wrong way — and Derek's body chose the only coping mechanism it had left, folding him back into the wolf like armor.

Stiles learned to weather it.

"It's okay," he'd say, settling beside the wolf, fingers in the black fur. "You're safe. You can come back when you're ready."

Sometimes Derek came back in minutes. Sometimes it took hours. Once, after a particularly vicious nightmare — Stiles felt it through the bond, fire and screaming and the specific sensory memory of someone he loved trying to kill him — Derek was wolf for three full days, and Stiles stayed in the tower the entire time, reading aloud, talking, letting the wolf press against him and breathe.

Deaton monitored the bond's progress with his usual maddening objectivity. "The feral state isn't a switch," he explained. "It's a spectrum. Derek's baseline has shifted dramatically — his default is now human rather than wolf, which is a reversal that the literature would call unprecedented. But the neural pathways of the shift are deeply grooved. Under sufficient stress, they'll reassert themselves. With time, with stability, with the ongoing anchor of the bond—"

"With me," Stiles translated.

"With you," Deaton agreed. "His brain is rewiring. You're the template it's organizing around."

The weight of that — the enormity of being someone's psychological architecture — settled on Stiles like a second skin. He carried it carefully.

Derek, in his human hours, was — not what Stiles expected.

He was quiet. Quieter than the boy on the balcony had been, and the silence had a different quality now: not the comfortable reticence of someone who chose his words carefully, but the guarded stillness of someone who wasn't yet sure his words were reliable. He spoke in short sentences. He flinched at loud noises. He stood at windows and stared at the Preserve with an expression of homesick longing that made Stiles's heart hurt, because the forest was right there but Derek was afraid of what it would mean if he went into it — afraid that the wolf would find it easier than the keep, easier than the human world, and he'd never come back.

But there were moments.

Derek's dry humor surfacing through the silence like a fish breaking water — brief, glinting, surprising. The first time Derek cooked in the keep's kitchen, moving with the muscle memory of someone who'd done this a thousand times before, making a simple stew that was somehow the best thing Stiles had ever eaten. The way Derek would press his nose into Stiles's neck — still the wolf's gesture, the scent-seeking nuzzle — and then catch himself and start to pull away, and Stiles would put a hand on the back of his neck and hold him there and say, "You don't have to stop doing that just because you're human-shaped."

(And in the dark, in the nest, the wolf's other habits persisted too. Derek would mouth his way down Stiles's body with a focus that went beyond human desire into something instinctive and compulsive — settling between Stiles's thighs and staying there with an unhurried devotion that left Stiles shaking and incoherent and struggling to remember his own name. And afterward, always afterward, licking him clean with a tenderness that made Stiles's chest crack open every time. "It's a wolf thing," Derek muttered once, flushed and human and not quite meeting Stiles's eyes as he wiped his mouth with the back of his hand. "The — I can't explain it. You taste like — we taste like—" He stopped. Stiles, still catching his breath, said, "If you finish that sentence with the word 'mine,' I'm going to spend the rest of my life getting weak in the knees every time you use a possessive pronoun." Derek didn't finish the sentence. But the look he gave Stiles was answer enough.)

The way Derek looked at him sometimes, with those green-gold eyes, like he was solving a puzzle he couldn't believe existed.

"You stayed," Derek said one evening. They were in the nest — they still slept there, in the tower, because the bed in the royal chambers felt too exposed for Derek and the nest felt like theirs. Derek's head was in Stiles's lap, and Stiles's fingers were in his hair, and the bond between them was a warm, steady thrum. "They told you what I was, and you walked into the tower, and you stayed."

"Of course I stayed."

"There's no 'of course' about it, Stiles. I was an animal. A dangerous one. My own family couldn't reach me. And you — a stranger, an omega who'd been traded without his consent — you sat down on the floor and started talking, and you..." He trailed off. The bond pulsed with an emotion Stiles couldn't name. "You talked to me like I was a person. The whole time. Even when I couldn't understand the words. You never talked to me like an animal."

"You weren't an animal."

"I was."

"You were a person in pain. The wolf was how you survived. And honestly, I've seen less functional coping mechanisms — have I told you about Scott's phase where he dealt with stress by learning to juggle? He's terrible at it, Derek. It's been years and he still can't manage three balls."

Derek huffed a laugh. It was the closest thing to a full laugh Stiles had gotten from him yet, and Stiles hoarded it like a jewel.

"You make me laugh," Derek said quietly. "You make me feel — human. Not because the shift recedes when you're near, although it does. Because you treat the human parts of me like they're worth staying for."

"They are."

"You don't know that. You knew me for one hour on a balcony six years ago."

"And in that hour, you were the most real person I'd ever met. And now I know you in ways that go deeper than hours — I've been inside your head, Derek. Through the bond. I've felt your grief and your guilt and your love for your family and your dumb opinions about druidic history, and all of it — all of it is worth staying for."

Derek was quiet for a long time. Then he turned his face into Stiles's stomach and pressed a kiss there — soft, deliberate, a human gesture chosen with the gravity of someone who understood what it meant to be able to choose.

"I love you," Derek said into Stiles's skin. "I think I've loved you since the balcony. I think the wolf knew before I did."

Stiles's eyes burned. His hand tightened in Derek's hair.

"I love you too," he said. "For the record, I've been gone since the pocket pastry comment. You had me at lukewarm appetizers."

Derek's laugh this time was real — full and warm and broken at the edges, the laugh of a man who was remembering how joy worked. Stiles pulled him up and kissed him, slow and deep and tender, and the bond sang between them like a chord resolving.

Lydia was the one who found it.

She'd been systematically working through the Hale library for weeks, cross-referencing diplomatic records and trade agreements and druidic archives with the focus of someone who'd been given access to the finest magical library on the continent and intended to read every word. Stiles had assumed she was pursuing academic interest. He'd underestimated her.

"The fire wasn't an isolated attack," Lydia said, spreading documents across the table in Stiles's chamber with the controlled urgency of someone who'd been sitting on a revelation for twelve hours and was about to detonate. "Kate Argent didn't act alone, and the objective wasn't Derek."

Stiles looked at the documents. Trade routes. Troop movements. A timeline of Argent Confederacy diplomatic overtures spanning five years before the fire.

"The Argents wanted the Preserve," Lydia continued. "The land itself. The ley lines that run through it are the strongest on the continent — every druidic treaty, every magical alliance, every ward system in a thousand miles is anchored to the Hale Preserve. If the Hale pack fell, the Preserve would be undefended. The Argents could claim the ley lines and reshape the entire magical power structure of the region."

"The fire was supposed to destroy the pack."

"The fire was phase one. Kate was sent to identify the keep's defenses from inside, and the fire was meant to kill the alpha line — Talia, Laura, Derek. Without an alpha heir, the pack bond would dissolve, the territorial wards would fall, and the Argents could move in under the pretext of 'stabilizing the region.'"

"But Derek survived. He saved his family."

"He saved his family and lost himself, and the result was almost as good for the Argents as a successful assassination. A feral alpha can't maintain territorial wards. Talia's been holding the Preserve's defenses herself for two years, and she's not the alpha — Derek is, even feral, because the pack bond recognizes him. The wards are weakening, Stiles. They've been weakening since the fire, and if Derek doesn't recover fully — if he can't resume his role as territorial alpha—"

"The Preserve falls. The ley lines are exposed. The Argents get what they wanted all along." Stiles stood up. His mind was racing, connections sparking like flint on steel. "That's why the alliance terms were so generous. Talia wasn't just trying to save her son. She was trying to save the Preserve. If Derek recovers, the wards hold, and the Argents' plan fails."

"And if he doesn't recover," Lydia said, "then the military alliance with Beacon is a fallback — enough strength to defend the Preserve by conventional means while they search for another solution."

"Does Talia know all this?"

"I don't know what she knows. But Peter does." Lydia's expression was sharp as glass. "Three of these trade agreements bear his signature. He's been negotiating with the Argent Confederacy since six months after the fire."

The world went very still.

"Negotiating what?"

"Access rights. Limited access to the southern Preserve in exchange for — the documents are vague. But the implication is clear. Peter has been selling pieces of the Preserve's magical territory to the Argents. Slowly. Carefully. In ways that wouldn't be noticed unless someone was specifically looking."

"While Derek was feral. While no one was watching."

"While everyone was focused on Derek's recovery. Or lack thereof."

Stiles thought about Peter's smile. I'm not your enemy, Stiles. But I'm not your friend, either. The pragmatist hedging his bets. Except it was worse than hedging — he'd been actively selling the kingdom's most vital asset to its greatest enemy while his nephew was locked in a tower losing his mind.

"We need to tell Talia," Stiles said.

"We need to tell Derek."

Stiles hesitated. Derek was fragile. The recovery was real but not stable — he still shifted involuntarily under stress, still lost hours to the wolf, still woke thrashing from nightmares of fire and betrayal. The news that his uncle had been collaborating with the woman who'd destroyed his life—

"It could set him back," Stiles said. "It could—"

"Or it could be the thing that brings him all the way back." Lydia met his eyes. "Derek isn't fragile, Stiles. He's recovering. And recovered people need the truth, even when it's terrible. Especially when it's terrible. You can't protect him from reality and expect him to live in it."

She was right. Lydia was almost always right, which was both her greatest gift and the single most irritating thing about her.

Stiles told him in the tower, at dusk, with the windows open and the forest breathing below.

Derek listened. He sat on the edge of the nest, hands between his knees, and he listened to every word, and Stiles watched the shift ripple under his skin — not taking over, but pressing, testing, the wolf responding to the rising tide of emotion that the bond was transmitting like a signal fire.

When Stiles finished, the silence lasted a long time.

"Peter," Derek said.

"Peter."

"He was — in the months before the fire. He introduced me to Kate." Derek's voice was very controlled. Too controlled, the kind of stillness that preceded earthquakes. "He said she was an emissary from a neutral territory. He said she was interested in the pack's history. He—" A pause. Something behind his eyes fracturing. "He set it up. He set all of it up."

"Derek—"

"He introduced me to the woman who burned my family, and then when I broke, he sold the Preserve to the people who sent her." The shift surged. Derek's hands clenched and his claws punched through, his eyes flickering red, and a snarl built in his chest that made the stones vibrate. "He—"

"Stay with me." Stiles moved to kneel in front of him. He took Derek's clawed hands and held them, and the bond blazed between them, Stiles pouring every ounce of calm and steadiness he had through the connection. "I know. I know what you're feeling. I can feel it, and it's — enormous, and you have every right to it. But I need you to stay with me. Don't let it take you."

Derek's eyes were red. Fully red. His jaw was elongating, the shift pulling at him with a force that Stiles could feel through their bond like a riptide. The wolf wanted out. The wolf wanted to run, to hunt, to destroy the thing that had hurt them, and the pull was so strong that Stiles could feel his own body responding, omega instincts flaring in alarm at the alpha's distress.

"Derek." He put his forehead against Derek's. Skin to skin. "You're not the wolf. You're not the man. You're both, and both of them are strong enough to survive this. Stay."

The shift held at the edge. Trembling. Derek's breathing was ragged, his body caught between forms, and Stiles held his face and breathed with him — in, out, in, out — and slowly, so slowly, the red receded. Green bled back in. The claws retracted.

"Stay with me," Stiles whispered.

"I'm here," Derek gritted out. "I'm here."

He didn't shift. For the first time, faced with a trauma response that should have sent him spiraling into the wolf, he didn't shift. He shook, and he raged, and at one point he put his fist through the tower wall hard enough to crack stone, but he stayed human. He stayed.

The confrontation with Peter happened in the great hall, with Talia presiding and Stiles's documentation spread across the council table like evidence at a trial. Peter was calm throughout — eerily, infuriatingly calm, that practiced smile never wavering even as Lydia laid out the paper trail with surgical precision.

"I did what was necessary," Peter said. "The pack was leaderless. The Preserve was vulnerable. The Argents were going to come regardless — I chose controlled concession over uncontrolled invasion."

"You chose yourself," Derek said. He was standing. He hadn't sat down. "You chose power, and you used my — my condition as cover."

"I preserved the kingdom, nephew. Something you were notably unable to do."

The hall went silent. Stiles saw Derek's hands clench at his sides, the claws threatening to emerge, and he felt the shift pressing through the bond — but Derek held it. He looked at his uncle with human eyes, green and burning, and said:

"You're exiled. Pack bonds severed. You leave Triskelion by dawn or I deal with you as alpha, not as nephew."

Peter's smile finally cracked. Just a fraction, just a fissure, but it was there — the first real expression Stiles had ever seen on his face. Surprise. And underneath it, very faintly, something that might have been respect.

"Welcome back, Derek," Peter said.

He left. Talia's enforcers escorted him to the border, and the pack bond severed with a snap that Stiles felt through Derek — a cold, clean cut, like a dead branch falling from a tree.

Derek didn't shift that night. Or the next day, or the next. The wolf was still there — Stiles could feel it through the bond, a warm presence curled around Derek's core — but it was no longer fighting for control. It was resting. Content.

Mate is safe, the wolf seemed to say. Pack is safe. We can stay.

"I want you to know that you can leave."

It was a month after Peter's exile. Derek said it in the morning, sitting across from Stiles at the small table they'd moved into the tower because they both still preferred sleeping there, in their nest, surrounded by furs that smelled like both of them. His hands were wrapped around a mug of tea and his expression was careful — the particular careful that meant he'd been rehearsing.

Stiles set down his fork. "Excuse me?"

"The alliance is sealed. My recovery is — progressing. Deaton says the bond is stable enough that distance wouldn't—"

"Derek."

"—dissolve it, and your father needs you in Beacon, and I know this was never — you didn't choose this. Not really. You were sold to a situation that no one told you the truth about, and I—" He swallowed. "I owe you your freedom. More than I owe you anything else."

Stiles looked at him for a long time. At the serious face, the earnest eyes, the hands gripping the mug too tight. At the man who'd clawed his way back from the abyss because Stiles had sat on a stone floor and started talking and hadn't stopped.

"You're an idiot," Stiles said.

"I'm trying to be—"

"Noble. Self-sacrificing. Allergic to happiness. I recognize the symptoms." He reached across the table and took Derek's hand. The grip he got back was immediate and fierce. "Derek. Listen to me. I am going to say this once, very clearly, so that both you and the wolf understand, because I know he's listening."

Through the bond: warmth. Attention. The wolf's ears pricking up.

"I. Am. Staying. Not for the alliance. Not for Beacon. Not out of obligation or pity or some misguided sense of duty. I'm staying because I love you. Both of you. The man who laughs at my jokes and argues about druidic history and makes terrible stew—"

"My stew is excellent—"

"—and the wolf who put his head in my lap on the fourth night and breathed like he'd been holding his breath for two years. I'm staying because when you're not in the room, I feel it like a missing limb. I'm staying because I chose you in that tower, and I choose you now, and I will keep choosing you every day for as long as you'll let me. So can you please stop trying to give me an out I don't want?"

Derek stared at him. His eyes were very bright.

"You said my stew is terrible."

"That's what you're taking from this?"

"Your romantic declarations need work."

"Oh my god, I hate you—"

Derek pulled him across the table. The kiss was clumsy and off-center and tasted like tea, and Derek was laughing into it, and Stiles was laughing too, and the bond between them was singing, actually singing, a resonance that filled the tower room like music.

"Stay," Derek said against his mouth. Not a question. Not a plea. An invitation, offered freely, with both hands open.

"Always," Stiles said.

The formal ceremony was held in the great hall of Triskelion Keep, three months after Stiles had arrived at its gates as a bargaining chip and a stranger.

This time, both grooms were present.

Derek stood at the center of the hall in the Hale colors, cleaned up and sharp-jawed and so achingly handsome that Stiles's brain briefly short-circuited. His eyes were green. They stayed green. At his side, Laura stood as his second — no longer the guilt-hollowed woman who'd met Stiles in the courtyard, but someone straighter, lighter, beginning to resemble the laughing girl from the gala.

Talia watched from the front row. She was crying before the ceremony even started. Scott, standing at Stiles's side as his second, handed her his handkerchief without being asked, because Scott was like that.

Lydia was in the second row, wearing an expression of serene satisfaction and sitting next to a truly enormous stack of books she'd borrowed from the Hale library with the stated intention of returning them "eventually." No one believed her.

Deaton performed the bonding rites again — the same words, the same old tongue, the same oil on Stiles's wrists and throat. But this time Derek was there to receive them. This time, when Deaton said do you accept this bond, Derek looked at Stiles with eyes that held two years of darkness and the slow, hard-won dawn that had followed, and said—

"I accept."

Stiles's hands were shaking. He didn't care. "I accept."

The bond — already deep, already woven into both of them at the cellular level — blazed. Stiles felt it like sunlight through his whole body, a warmth that started at the bite mark on his neck and radiated outward until his fingertips tingled. Through the connection, he felt Derek: joy, fierce and incredulous, the joy of a man who had genuinely believed he would never be happy again and was discovering that he'd been wrong.

The hall erupted. Wolves howled — full-throated, joyous, the pack bond resonating with its alpha's happiness. Somewhere in the crowd, Scott was trying very hard not to cry and failing spectacularly. Lydia looked at them with an expression that, on anyone else, would have been called mushy.

"If you make me emotional in public, I'll deny it," she told Stiles afterward.

"Your eyes are red, Lydia."

"Allergies."

They went back to the tower.

Not because they had to. The royal chambers had been prepared, the ancestral suite with its enormous bed and its view of the Preserve and its walls hung with Hale history. But the tower was theirs — the stone floor where Stiles had sat and talked to a wolf, the nest of furs where Derek had first laid his head in Stiles's lap, the window where the moonlight fell in a pattern they both knew by heart.

"One more night," Stiles said. "Before we move downstairs and start being normal royalty."

"Were you ever normal?"

"Not even slightly."

Derek smiled. He did that more now — not often, not easily, but with a growing frequency that Stiles tracked like a meteorologist tracking fair weather. Each smile was a data point. Each laugh was a trend line pointing upward.

The nest was as they'd left it. Furs, cushions, the blanket Stiles had brought from Beacon on his first night that still smelled like both of them. They settled into it, and Derek pulled Stiles against him — chest to back, arms around his waist, nose in the crook of his neck where the mating bite had scarred into a permanent mark.

"Thank you," Derek murmured against the scar. "For staying. For talking. For every stubborn, relentless, ridiculous thing you did to bring me back."

"You brought yourself back. I just gave you something to come back to."

"You gave me everything."

Stiles turned in his arms. In the moonlight, Derek's face was the face from the balcony — older, marked by what he'd survived, but the same. The same serious mouth, the same luminous eyes, the same quality of attention that made Stiles feel like the only person in the world.

"Hi," Stiles whispered.

"Hi."

"So I have a confession."

"What?"

"That night at the gala. I had two pastries in my pocket. I ate one to be defiant, but I was saving the other one to offer to you if the conversation went well. As, like, a flirtatious gesture. A meat pastry. As flirtation. I was sixteen and had no game."

Derek's laugh was startled and real and warmer than the furs. "That's the worst flirting strategy I've ever heard."

"It would have worked. You were already into me. Laura told me."

"Laura talks too much."

"Laura is a gift. Admit it. You wanted the pastry."

Derek's eyes softened. He cupped Stiles's face, thumb tracing the line of his cheekbone, and looked at him with an expression that the bond translated as: I wanted everything. I just didn't know I was allowed to have it.

"I wanted you," Derek admitted.

Stiles kissed him. Slow, this time. No urgency, no desperation, no heat-driven need pulling them together. Just the choice — deliberate, human, freely made — to press his mouth to Derek's and feel the bond hum its approval.

Derek's hands slid down Stiles's body. Slow. Reverent. Mapping him with human fingers, human sensitivity, learning the topography of skin and muscle and the places that made Stiles's breath catch. The hollow of his throat. The curve of his hip. The sensitive inside of his wrist, where the scent gland lived, where Derek pressed a kiss and inhaled and made a low sound of satisfaction that vibrated against Stiles's pulse.

"I want—" Derek started.

"Yes."

"You don't know what I was going to say."

"I don't care. Whatever it is. Yes."

Derek huffed against his wrist. Then he laid Stiles back in the furs and kissed his way down his body — throat, chest, stomach, the jut of each hip — with a tenderness so careful it made Stiles ache. This wasn't the feral urgency of their first time, or the desperate intensity of the second. This was a man taking his time. Choosing every touch. Savoring.

"You're shaking," Derek murmured against his belly.

"You're doing that thing with your mouth. I'm only human."

"Omega."

"Don't get semantic with me while you're—" Stiles gasped as Derek's mouth found the crease of his thigh, tongue tracing the sensitive skin there. "—making me lose my mind."

Derek looked up at him, chin resting on Stiles's hip, eyes bright with amusement and desire in equal measure. Through the bond: a warm pulse of let me. Let me take care of you.

Stiles let him.

Derek's mouth on him was devastating — unhurried, thorough, attentive in a way that felt like worship. He licked Stiles open with a patience that bordered on cruelty, tongue pressing deep while Stiles writhed and gasped and gripped Derek's hair and said things that weren't words. The slick came in waves, arousal and biology conspiring, and Derek groaned against him like Stiles's taste was something he'd been starving for.

"Please," Stiles managed. "Derek, please—"

Derek rose over him. Human. Completely, beautifully human — broad shoulders, dark hair, green eyes that held no flicker of red, no trace of the wolf's crimson. The wolf was there, always, curled contentedly at the base of Derek's consciousness, but tonight it was resting. Tonight it had given the man the helm, entirely and without reservation, because mate was here and mate was happy and that was all that mattered.

He slid inside Stiles face to face, and they both made a sound — a shared, breathless oh that the bond carried between them until it echoed. Stiles wrapped his legs around Derek's waist and pulled him deeper, and the fullness was exquisite, a pressure that wasn't just physical but emotional — the bond tightening between them, every nerve ending aligned, every sensation shared.

Derek moved in him slowly. Rolling his hips in deep, deliberate strokes that Stiles felt everywhere — in his body, in the bond, in the place behind his ribs where he kept the things he was afraid to lose. He held Derek's face in his hands and watched his eyes, and Derek watched his, and the vulnerability of it — the openness, the total absence of walls or armor or the protective distance that both of them had worn their entire lives — was more intimate than any physical act.

"I love you," Derek said. Not a confession this time. A fact. Simple and unshakable as gravity.

"I love you," Stiles answered. "I love you, I love you, I—"

Derek kissed the words out of his mouth and quickened his pace, and Stiles arched into him, and the pleasure built between them — shared through the bond, amplified by the feedback, climbing and climbing until Stiles couldn't tell where his body ended and Derek's began. The knot swelled, pressing against him, and when it locked them together, Stiles came with a cry that Derek swallowed, and Derek followed him, forehead pressed to Stiles's, breath mingling, eyes open, seeing each other.

They lay tangled in the furs, knotted together, and the moonlight moved across the tower floor, and the Preserve breathed below them, and Stiles thought: This. This is what I was saving the pastry for.

"I can feel you being ridiculous through the bond," Derek murmured.

"You love it."

"I love you. The ridiculousness I tolerate."

Stiles laughed, and Derek held him tighter, and the wolf stirred contentedly in the depths of the bond, and outside the tower the forest stretched to the horizon, vast and ancient and safe.

Epilogue

Six months later, a letter arrived in Beacon, sealed in black wax stamped with the triskelion. King John Stilinski opened it at his desk, in his study with its water-stained maps and its smell of ink, and his shoulders did something they hadn't done in years.

They relaxed.

Dad,

The Preserve wards are restored. Derek completed the territorial ritual last week — full alpha shift, voluntary and controlled, for the first time since the fire. He ran the entire border in wolf form and came back human, and laughed, and I cried, and we're not going to talk about that part in official correspondence so please forget I mentioned it.

The Argent situation is being handled. Lydia has composed a diplomatic response so devastating that I'm pretty sure it qualifies as a weapon of mass destruction. The short version is: they're retreating. The alliance holds. Beacon is safe.

Scott says hello. He's been training with the Hale guard and is annoyingly good at it. He's also been making eyes at a beta healer named Allison whose last name I am choosing not to investigate because some things are better left unknown.

I miss you. We're coming to visit next month — Derek wants to meet you properly, and I want to sleep in my old bed and eat your terrible cooking and pretend for a few days that I'm just your kid and not the omega consort of a werewolf kingdom.

But Dad — I'm happy. I'm really, truly, absurdly happy. I know you made an impossible choice when you said yes to this, and I know it cost you, and I want you to know: it was worth it. Not because of the alliance. Because I found him. Or he found me. Or a wolf in a tower found an omega with a pocket full of pastry crumbs, and neither of us had the sense to walk away.

I love you. I'm coming home soon.

Your son, Stiles

P.S. — Derek says to tell you that your kingdom's border fortifications are, and I quote, "structurally concerning." He's sending engineers. Don't argue. It's an alpha thing.

P.P.S. — You should probably make up the nursery when you're preparing for our visit. Not for any particular reason. Just... a hunch. A very strong, Deaton-confirmed, due-in-six-months kind of hunch. Derek cried. I cried harder. The wolf hasn't stopped nuzzling my stomach for three days straight and I have to physically remove him to get dressed in the morning. You're going to be a grandfather, Dad. Start practicing your "concerned but supportive" face.
