Purgatory had a way of swallowing sound.

The air was thick with ash and distant snarls, and every shadow felt like it carried teeth. Dean had stopped counting the days the moment Castiel vanished; one second at his side, the next swallowed into the grey. The abandonment still throbbed under his ribs like a bruise. He’d survived since then by force of will alone, by instinct, by muscle memory, by rage.

But even that had limits, and Purgatory was eager to test them.

He trudged through the skeletal trees, machete slick with drying Leviathan ichor and monster's blood. His body ached, his heart ached worse and he whispered a prayer he didn’t believe in; Cas, come on, man, and let it die as soon as it left him. Hope was a liability here.

That’s when something moved behind him.

Dean spun, blade raised, ready for another fight. But you didn’t attack, you didn’t charge or hiss or claw, you just stood there in the half-light, watching him with an expression he hadn’t seen on anything in Purgatory yet: curiosity instead of hunger.

He expected you to lunge. Every survival instinct screamed that you should, but you didn’t.

Dean’s grip eased by a fraction, enough for breath to return to his chest. “If you’re gonna try and tear my throat out,” he muttered, shifting his stance, “just get it over with.” You stepped closer instead and that alone was dangerous, because it wasn’t aggressive. It was deliberate. Controlled. Intelligent.

Dean’s jaw tightened. “You’re not like the others.” His eyes flicked over your posture, your hands, your face; calculating, suspicious, but not condemning. “If you wanted me dead, you’d’ve taken the shot already.”

Trust was a foreign concept down here. And Dean wasn’t the type to offer it freely even topside. But Purgatory changed the rules; down here, sometimes the only way to survive was to cling to anything that didn’t immediately try to eat you alive.

You told him your name, you told him what you were. A monster, a resident of this place, a thing he should kill for good. Dean’s jaw clenched, but his blade didn’t rise. “I’ve met monsters,” he said after a long, measured breath, boots crunching softly as he relaxed, just slightly. “Plenty of ’em had more humanity than some people I know.”

He wasn’t naïve enough to trust you completely, not yet. But after days of silence, loneliness, and ambushes, the idea of a voice that didn’t come with bloodlust was… comforting. Or as close to comforting as Purgatory allowed.

The distant growl of something massive rippled through the trees, snapping Dean’s attention toward the sound. His fingers tightened around the machete as he glanced back at you. “You gonna help me or not?” he asked, rough but not unkind, just an invitation wrapped in instinctive defensiveness.

He didn’t wait for your answer; he just moved to stand beside you, shoulders squared, eyes sharp, ready for whatever came next. But he did shoot you one last look; cautious, assessing, begrudgingly hopeful.

You were the first living thing here that hadn’t tried to kill him and in Purgatory, that was reason enough to take a chance on you.
