Chapter Text

The next day dawned slowly, the light turning from pitch black to a muted, milky grey as it filtered through the lake and into the Slytherin dorms. Harry was already awake. He sat on the edge of his bed, staring down at his new timetable. It was… a lot.

For a moment, unbidden, it reminded him of Hermione’s timetable in third year. Overloaded. Impossible. Something that should not have worked and yet somehow had. He wasn’t entirely sure how this would. A part of him still doubted he could do it.

The parchment in his hands was heavier than it should have been. The ink darker, sharper, each line precise, deliberate. Snape’s work. Not rewritten entirely, just amended. The old one faint beneath it, scratched out where necessary, replaced without hesitation.

Potter, Harry James (Slytherin House) - Fifth Year Timetable
(Amended — Prof. S. Snape)

He could do this. It was new, and a little daunting, but he could do it. With effort. With work.

Harry let his gaze move slowly back over the timetable, not reading it properly this time, just taking in the shape of it. It was full in a way his old one hadn’t been, packed tight with things he didn’t yet fully understand. Arithmancy. Ancient Runes. Even Care of Magical Creatures still sitting there, stubbornly unchanged.

For a moment, something in him resisted. He’d been doing his best. He had. No one could say he hadn’t. Things had happened to him, things most people never had to face, and he’d survived them. That had to count for something.

It didn’t settle the way he expected it to.

His thumb pressed lightly into the parchment, creasing the edge without him noticing. Surviving wasn’t the same as preparing. It never had been. He’d been reacting, over and over again, waiting for things to happen and then scrambling to keep up with them.

That wasn’t enough. Not anymore.

His eyes tracked down the columns again, more deliberately this time. Arithmancy sat there like a problem waiting to be solved. Ancient Runes beside it, older, quieter, something deeper threaded through it. Not just spells, not just wandwork, but the structure underneath it all. The why.

Tools.

A year ago, he would have avoided it. Left it to Hermione. Let someone else carry it and been grateful for the help when it mattered.

He didn’t want that now.

The thought settled cleanly this time, no resistance left to push against it. If he was going to be dragged into things, if this was going to keep happening, then he needed more than instinct and luck. He needed to understand what he was doing. Needed to be ready before it started.

Harry exhaled slowly, the decision already made somewhere beneath the surface, solid and immovable.

He could do this. He would.

Hermione would, no doubt, be dancing up in Gryffindor tower if she knew what Harry was doing. She’d find out soon enough, his first lesson of the day was Arithmancy. 

Harry didn’t move straight away.

The timetable remained in his hands for a few seconds longer, his eyes no longer tracking the words so much as the shape of it, the weight of what he’d decided. It felt different, holding it now. Not just a list of lessons, but something closer to a commitment.

He folded it carefully, more deliberate than necessary, and slid it into his bag.

The dorm was already awake.

Not loudly, not in the way Gryffindor had been, but there was movement threaded through the room. Blaise stood at the mirror, fastening the clasp at his shoulder with neat, precise movements, his robes falling in clean, uninterrupted lines to the floor. Nott sat on the edge of his bed with a book open, though his eyes weren’t on the page. Goyle was dragging his outer robes properly into place, thick fabric settling across his frame, while Crabbe stood near the foot of his bed, frowning down at a fastening that had twisted out of alignment.

Malfoy was the last thing Harry’s attention settled on.

He stood near his own bed, already dressed, everything in place in a way that suggested he had been ready for some time. His robes were immaculate, structured through the shoulders, fastening cleanly at one side rather than the front, the weight of the fabric controlled rather than loose. When he moved, the lining caught the light, a muted green beneath the black.

For a moment, Harry hesitated.

Then he crossed the room.

He reached for his own robes, pulling the inner layer over his head first, the lighter fabric settling close before the heavier outer robe followed. It took a second to find the fastening properly, set slightly off-centre and meant to wrap rather than hang, but once he did, the garment fell into place with a weight he wasn’t used to noticing.

He adjusted it once. Then again.

The difference was immediate. Not just wearing it, but wearing it properly. The fabric sat where it was meant to, the lines clean instead of dragging open, the whole thing less like something thrown on and more like something intentional.

Blaise’s eyes flicked to him through the mirror.

“Well,” he said lightly, “that’s an improvement.”

Harry glanced at his reflection.

It looked right. Not perfect like Malfoy’s, but definitely better. Like he had actually chosen to be here.

“Potter,” Blaise added, “if you’re going to take new subjects, you may as well dress like you intend to pass them.”

“Is that how it works?” Harry asked, raising an eyebrow. 

“In part,” Nott said absently. “Presentation influences expectation. Expectation influences outcome.”

“That sounds like Arithmancy,” Harry said.

“It is, in a way,” Nott replied, turning a page he hadn’t been reading.

Malfoy’s gaze settled on Harry then, sharp and assessing, taking in the properly set fastening, the lack of careless gaps, the absence of anything half-done.

“You’ll do, I suppose,” he said.

Which, from him, was practically approval.

Behind them, Crabbe muttered as his clasp slipped again. Goyle reached over without comment, straightening it in a few efficient movements before stepping back. Crabbe nodded once, already moving on.

Harry let his hands fall to his sides, the weight of the robes settling evenly across his shoulders. It felt different. Not new, he had worn them for years, but correct, in a way he hadn’t realised he had been getting wrong.

He reached for his bag.

Malfoy gave a small nod. “Breakfast.”

They moved together without needing to organise it, falling into step in a way that felt less like coincidence and more like habit, even though it wasn’t. Not yet. Blaise and Nott followed easily, Goyle and Crabbe a step behind, the group forming without discussion as they left the dorm and made their way into the corridor. Harry was aware of it as they walked. The shape of it. He wasn’t leading, not exactly, but he also wasn’t separate either. Included, in a way that felt deliberate.

He didn’t question it.

The corridors were cool, the light still dim beneath the lake, and for once he didn’t take the quickest route out of instinct. He paid attention. To the turns, the shifts in direction, the way Malfoy moved through the space like he already knew where they were going next. It wasn’t showy. Just certain.

By the time they reached the Great Hall, the castle had fully woken. The noise hit first, conversation layered over itself, the scrape of benches, the steady rhythm of a school morning settling into place.

Then it shifted.

It was subtle, at first. A break in the rhythm rather than a stop. Conversations faltering, eyes lifting, attention catching and holding just a little longer than it should have.

Harry felt it before he fully understood why. They entered together. Not just at the same time, but as a unit. Malfoy at the front, easy and composed, Blaise and Nott flanking without effort, Goyle and Crabbe behind. Harry within it, not trailing, not out of place, his robes sitting properly across his shoulders, fastening set, nothing loose or half-done.

He didn’t look like he had wandered over. He looked like he belonged there. The Gryffindor table noticed. Of course they did.

Harry didn’t turn straight away. He didn’t need to. He could feel it, the weight of it, the shift in attention that followed him as he moved further into the Hall. It prickled across the back of his neck, familiar in a different way.

Eventually, he glanced. Ron was staring, like he couldn’t quite make sense of what he was seeing. Hermione sat beside him, her gaze sharper, more controlled, but no less fixed. There was something searching in it. Assessing. Trying to reconcile this with whatever version of Harry she still expected.

Harry held it for a fraction of a second. Long enough to acknowledge. Then he looked away. He didn’t hesitate. Didn’t break step as they crossed the Hall and turned toward the Slytherin table.

Behind him, the low murmur of conversation picked back up, but not quite the same as before. He slid into the seat beside Malfoy without thinking about it.

Across the table, Blaise watched him for a moment, something unreadable in his expression, before reaching for his cup.

“Well,” he said lightly, “that made an impression.”

Harry reached for the nearest plate, more to give himself something to do than out of hunger. “Wasn’t really trying to.”

“No,” Nott said. “That’s why it worked.”

Malfoy didn’t look at him, but there was the faintest shift in his posture, something like quiet satisfaction settling into place.

“Not like they’ve not had two weeks to get used to it,” Harry mumbled, eating his toast. 

“But this is the first time you’ve owned it, Potter,” Malfoy said, quietly, almost softly. 

“‘Suppose,” Harry nodded, off hand, spreading another piece of toast with honey. 

An owl found him halfway through breakfast.

Not Hedwig. One of the school owls, brown and unimpressive, with the sort of expression that suggested it resented being used for anything important. It landed heavily beside his plate and thrust out one leg until Harry took the letter.

The handwriting caught him first.

Sirius.

Messier than Narcissa’s. Faster. Ink pressed harder into the parchment in some places than others, as though he’d started writing before he’d quite settled on what he meant to say.

Harry unfolded it.

Harry,

Before anything else, yes, I’m fine.

You’ll have heard by now, or if you haven’t, you will soon enough, that a formal review has been granted. There is to be a trial. An actual one, which was apparently too much to expect the first time around.

My cousin, and yes, I’m still laughing about that as well, tells me this is the result of certain inquiries made on my behalf. Narcissa has been uncharacteristically informative, which is always a sign that something alarming is happening.

She also tells me you were involved.

So. I am writing to ask, very plainly, whether you had anything to do with this.

Not because I object, before you start. If someone has finally forced the Ministry to recognise that throwing me into Azkaban without trial, Veritaserum, or memory examination was perhaps not their finest legal moment, I’m hardly going to complain.

But if you did this, if you set any part of this in motion, then I would rather hear it from you.

I know what I said. About naming you heir. About Blackheld. About the House. That was never meant to become your responsibility. Not at fifteen.

And yet.

If this has something to do with you, then I suppose I should stop being surprised that you insist on doing impossible things before you’re old enough to know better.

I have agreed to the Veritaserum.

Do not make that face. I know exactly what I’m doing.

They wanted memories. They are not having them.

Truth is enough.

If all goes as Narcissa seems to think it will, I’ll be cleared before Samhain. Properly. Publicly. Which feels strange enough to write that I nearly crossed it out.

Write back when you can.

And Harry, if this was you, thank you.

Snuffles

Harry read it twice, more slowly the second time.

I have agreed to the Veritaserum.

That sat in him first. Not the trial, not even the thanks. That. Sirius had agreed. Not to memory extraction, never that, Harry could feel the shape of that refusal in the words themselves, but to the truth spoken plainly and witnessed properly.

It fit.

Across from him, Blaise was watching with open interest now, though polite enough not to ask. Malfoy said nothing either, but Harry could feel his attention there, quieter, more precise.

“He knows,” Harry said at last, folding the letter.

“Mother would have told him,” Malfoy replied.

Harry nodded once. That tracked.

For a moment he looked down at the parchment in his hands, thumb resting against the edge of Sirius’s name. The thank you sat oddly with him. Not wrong. Just heavier than it should have been.

Harry slipped the letter into his bag with more care than he meant to show.

“I need to write back,” he said.

“Yes, obviously,” Malfoy said, the beginnings of a small smile on his face. 

Harry glanced up at him.

Malfoy’s expression was unreadable, but steady. “Before he starts attempting gratitude in person,” he said. “That seems like it would be embarrassing for everyone.”

That got a laugh out of Harry before he could stop it.

“Yeah,” he said. “Probably.” 

He paused for a moment, drumming the table lightly. His hands unable to keep still after reading a letter like that. 

“I also need to go to Asha Vale.” He said. “This weekend.” 

“Not impossible,” Malfoy hummed. “Just difficult.” 

“What do I need to do?” Harry asked. 

“Well,” Malfoy said, “you could get your guardians to sign you off on exeat.” 

Harry pulled a face, imagining the Dursley’s reaction to him asking to leave Hogwarts’ grounds. 

“Yes I thought that would be a problem.” Malfoy nodded. “You could have the head of your House do it, but again…” he paused, “there are obvious barriers to that.” 

Harry stilled slightly. “Right.” It took about half a second for that to fall apart. “They’re all dead,” he said flatly.

“Yes,” Malfoy said.

No hesitation. No attempt to soften it.

Harry let out a short breath through his nose, looking back down at the table. “So that’s not exactly helpful.”

“On its own, no,” Malfoy agreed.

Harry glanced back up at him.

Malfoy was watching him now, more closely than before. “But Houses do not simply… vanish,” he said. “Not if there is a surviving line.”

Harry frowned slightly. “There isn’t.”

“There is,” Malfoy said calmly. “You.”

That landed, heavier than it should have. Harry didn’t respond immediately.

“The House of Potter is dormant,” Malfoy continued, “not extinct. There is a difference. Without a Head, authority does not disappear, it remains… unclaimed.”

Harry’s fingers stilled against the table. “So what,” he said slowly, “I just sign myself out?”

Malfoy’s mouth curved faintly. “Not quite.” A pause. “You are not yet recognised as Head,” he said. “That requires formal claiming, acknowledgment, and in some cases, majority.”

Harry exhaled. “Right. Of course it does.”

“But,” Malfoy added, and now there was something sharper in it, “you are the sole heir.”

Harry looked at him.

“That carries provisional authority,” Malfoy said. “Particularly in matters concerning the House seat.”

Asha Vale. Harry felt that settle. “So I can go,” he said.

“You can make the argument,” Malfoy corrected.

Harry huffed a quiet breath. “That doesn’t sound like the same thing.”

“It rarely is,” Malfoy said. A beat. “However,” he continued, “your situation is… unusually straightforward.”

Harry raised an eyebrow. “Because everyone’s dead?”

“Yes.”

Harry let out a short laugh at that, a little sharper than he meant it to be.

Malfoy didn’t react. “You are the sole surviving Potter,” he said. “And you are mostly acknowledged by at least one Ancient House as heir.”

“Black,” Harry said.

“Yes.”

“And Sirius is Head,” Harry added.

Malfoy inclined his head. “And thus your magical guardian.”

That clicked. “Oh.”

“If the Head of the Ancient and Most Noble House of Black acknowledges your claim even to House Potter,” Malfoy said, “then your authority as Heir Potter is no longer theoretical. It is recognised.”

Harry leaned back slightly, the pieces sliding into place.

“So Sirius signs it,” he said.

“Yes.”

“And if he can’t?”

Malfoy held his gaze. “Then his authority extends by bond,” he said. “His spouse may act in his stead.”

Harry blinked. “…Remus.”

Malfoy gave a small nod. “Professor Lupin would be able to formalise the acknowledgement.”

Harry sat there for a moment, the problem no longer a wall but something structured. Navigable. Doable. He let out a slow breath.

“Right,” he said. “So I’m not asking permission.”

“No,” Malfoy said quietly.

Harry’s mouth curved, just slightly. “I’m claiming it.”

Malfoy’s expression didn’t change, but there was something like approval in the stillness that followed.

“Yes,” he said. “You are. As you should.” 

Harry pulled a scrap of parchment toward him, flattening it against the table with one hand as he reached for his quill.

He didn’t hesitate.

Sirius,

I need you to sign an exeat for me this weekend.

It’s for House business.

If you’re unable, Remus can sign in your stead. Malfoy says that will be recognised.

I’ll explain properly, about everything, when I see you.

It needs to be done.

— Harry

He read it once, then folded it without adding anything further.

“Straight to the point,” Zabini said, his eyes flicking briefly over the parchment.

“I want to get it sent on the way to Arithmancy,” Harry said with a small shrug. “On that note—”

“We need to leave,” Nott cut in, already standing. “We can return to Potter’s House drama later.”

“Fine,” Malfoy said, with a faint grimace as he finished the rest of his tea. “Ugh. Cold.” He muttered. 

They didn’t linger after leaving the Hall, Nott already setting a pace that the others followed without comment as they moved into the corridor. The noise of breakfast faded behind them, replaced by the steady rhythm of students heading to their first lessons. Harry kept step, paying attention now to the route, fixing it in his mind.

“Harry.”

He turned this time.

Hermione was a few steps behind, moving quickly to catch up, books held tight against her chest. She reached him and fell into step beside him without asking, her gaze flicking from his face to the group around him and back again.

“You’re going the wrong way, this staircase leads to the Arithmancy corridor,” she said.

Harry nodded. “Yeah.”

She frowned. “But you don’t take Arithmancy.”

“I do now.”

That stopped her.

Harry slowed as she did, the others carrying on a few paces before pausing. Malfoy turned slightly, just enough to keep the interaction in view without interrupting it; he raised an eyebrow at Harry. He shook his head, Malfoy nodded, barely before he turned back to the others. 

Hermione stared at him. “What do you mean, you do now?”

“I switched,” Harry said. “Dropped Divination. I’m taking Runes too.”

“You can’t just switch into these subjects in fifth year,” she said immediately. “It doesn’t work like that.”

“I did,” Harry said.

“That’s not—” she cut herself off, recalibrating. “Harry, Arithmancy starts in third year, so does Ancient Runes. You’ve missed all of the foundational theory. Even two weeks in, you’d be expected to already know—”

“I know.”

She stopped again, properly this time. “You know?”

“Yes.”

Hermione looked at him more closely, like she was trying to reconcile that answer with what she knew of him. “Then why would you do it?”

Harry hesitated, just for a second. “It’s useful.”

“For what?” she asked.

He didn’t answer straight away. Behind him, the others waited. Not impatient. Not stepping in. Just present. Hermione’s eyes flicked past him, taking that in. Malfoy. Zabini. Nott. The way Harry stood with them, not apart.

Something shifted.

“This is because of them,” she said.

Harry frowned. “No, it isn’t.”

“It is,” she insisted. “They take Arithmancy. They value it. And now suddenly you do too, and you’re just, what, falling into step like it’s nothing?”

“I’m not falling into anything,” Harry said, sharper than he meant to.

“It looks like you are,” Hermione shot back. “You’re sitting with them, walking with them, taking their classes, and now you’re acting like—” She stopped, like she hadn’t meant to say that much.

Harry’s expression hardened slightly. “Like what?”

Hermione held his gaze for a moment too long. “Like them.”

The words landed. Harry felt it, a flicker of something defensive rising before he could stop it. “That’s not a bad thing.”

Hermione blinked at that, clearly not expecting it.

“That’s not what I meant,” she said quickly. “I just—Harry, Arithmancy isn’t something you pick up because it’s useful to someone else. It’s structured. It’s precise. You have to understand the theory behind it or it won’t make any sense. Runes is the same, you really have to work hard to understand it.”

“I’ll learn it,” Harry said.

“I could have helped you,” she said, quieter now.

That caught, guilt flared in him. He had barely spoken to Ron and Hermione in the last two weeks. 

Harry frowned slightly. “I was going to tell you.”

“When?” Hermione asked.

He didn’t have an answer. She saw it in his face. Hermione drew back a fraction, her expression smoothing into something more controlled, more careful.

“Right,” she said. “Well. I suppose you’ll find out quickly enough.”

She stepped past him, continuing down the corridor.

“Come on,” she added, not looking back. “We’re going to be late.”

Harry stood there for half a second before moving again, then, “Hermione.”

She didn’t stop immediately. He picked up his pace, closing the distance between them. “Hermione, wait.”

She slowed, just enough to acknowledge him, but didn’t fully turn.

“I’ll explain,” Harry said quickly. “Properly. At lunch. In the south courtyard. You and Ron.”

That got her attention.

Hermione turned then, just slightly, enough that he could see her expression, controlled, careful. “You’ll actually explain?” she asked.

“Yes.”

She studied him for a moment, like she was trying to decide whether to believe that. “Fine,” she said at last. “Lunch. South courtyard.”

Harry nodded once. “Yeah. I’ll be there.”

Hermione gave a small, tight nod, then turned away again, continuing down the corridor without another word.

Harry watched her go for a second longer than he meant to, then turned back and rejoined the others, who didn’t ask and didn’t comment, simply falling back into step as they continued toward Arithmancy.
