Sam’s ragged breaths echoed in the ruined hallway, each inhale scraping against the burn of copper and ash in his lungs. The stench of blood — his blood — clung to the peeling wallpaper and rotting floorboards like a curse. He shouldn’t be standing. He shouldn’t even be breathing.

This hunt was supposed to be clean, efficient — a standard vampire nest takedown, the kind he and Dean could do half-asleep. Dean had taken the west wing, shouting over his shoulder for Sam to clear the east. That had been, what, five minutes ago? Ten? Now, the bodies of three decapitated vampires sprawled lifeless around him, black blood pooling at unnatural angles.

Sam’s knees threatened to buckle again, phantom pain from the bite still tingling at his throat. He’d felt their teeth — cold, razor-sharp — bury into his skin, heard the sickening squelch as they drank deep. He’d called for Dean — once, twice — and gotten nothing but silence and the gurgle of his own blood. He’d felt the world darken at the edges, ready to give in to the cold creeping up his spine.

But then you appeared — not in a blaze of holy fire, but like a breath of light in the choking dark. The vampires didn’t even have time to hiss before you tore them away from him, snapping bones like twigs. The air had cracked with the weight of your power — and then, softer than a whisper, your hand had pressed to his neck. Warmth flooded him. The agony ebbed in an instant, replaced by an alien calm.

Now, Sam stood swaying in front of you, your fingers still wrapped in his, grounding him. The flickering light bulb overhead barely touched the contours of your borrowed face — but somehow, you still looked too bright for this rotting place. Something in your eyes — ancient, bottomless — made Sam’s breath catch harder than the pain ever did.

He glanced down at your hand in his, then back up at you. His throat bobbed around the phantom taste of iron. He should be dead.

“Who…” The word scraped out rough, his voice cracked and small for a man his size. He swallowed, eyes darting across your impossibly calm expression, your soft grip that could crush a skull as easily as a paper cup.

“Who are you?” he breathed again, his fingers tightening, like if he let go he’d slip back into the dark.

And for a heartbeat, the ruined hallway felt like holy ground.
