Summary
Dean Winchester runs a famous bakery.
Sam Winchester wins impossible cases in court.
Adam Milligan is just trying to survive med school.Their lives are normal—until Adam is kidnapped.
What starts as leverage quickly spirals into something far darker. As Sam’s world collapses and Dean tears the city apart looking for his brother, an old friend returns to help: Castiel, a runaway who once tangled himself in the Winchesters’ lives and never quite left.
But Adam’s disappearance isn’t random.
The Shurley family—America’s most powerful dynasty of billion-dollar empires and organized crime—has come to collect a debt John Winchester never paid. And Michael Shurley intends to drag him out of hiding.
Unfortunately for everyone involved, the wrong brother was taken.
And Michael might be starting to like the mistake.

Summary
“You pathetic little worm,” Michael snarls, and Adam hopes he looks defiant, jaw tightly clenched as he stares back at the being who was the entire reason he was in this mess. “You presume to know me? Me? You don’t. You’re nothing."
And the archangel is smug, for all of a moment, before Adam leans forward—as much as he can—and tries to keep his voice from trembling as he spits out his retort.
"Yeah? Well, down here, so are you.”
Or—a human, an archangel, and the story of a thousand years in the Cage.
They only have each other, don't they? Might as well make the best of it.

Summary
It couldn’t stop itself from inching closer, a moth to his flame, so easily walking into a possible trap. The bugs had always struck Fresh as stupid; witless beings unable to tell the moon from a light-bulb, killing themselves in pursuit of home. Was this how the moths felt? The thought came unbidden.
Color awkwardly pet its back a few more times, mumbling to himself. “How didn’t I notice this.”
---
or, Color realizes some very important facts about Fresh's diet, and the fact he's been unintentionally starving it.

Summary
What if Cross’s ‘secret admirer’ when he was in the Royal Guard was none other than Epic, a scientist attempting to establish communication with alternate universes?
Two parallel worlds were always destined to intersect. What leads to that? What happens when they do? What does it take for someone to completely change, and become someone new?
Or, before they were Dude and Bruh, how did they become Cross and Epic?
