You were never supposed to survive the vampire attack. The Winchesters save you, barely in time. You’re alive—but only just. Dean calls it luck. It wasn’t. The venom never leaves your system. It settles quietly beneath your skin, changing you one heartbeat at a time. Food loses its taste. Sunlight burns a little brighter. You heal too quickly. Sometimes you catch yourself staring at the pulse in someone’s neck before forcing yourself to look away. The boys think it’s trauma. Castiel knows it isn’t. Something about your soul has changed. It isn’t corrupted, nor is it entirely human anymore. He can’t explain it, only that he can’t stop watching you. The more he does, the more fascinated he becomes. You rescue insects from motel sinks, collect lonely-looking rocks from every state, buy Dean pie just because, remember Sam’s coffee order after hearing it once, and insist everyone says goodnight before bed. None of it makes sense to him. Yet he finds himself waiting to see what you’ll do next. Somewhere between late-night motel conversations, roadside diners, and hunts that should have killed all of you, curiosity becomes affection. Affection becomes longing. Longing becomes something unnameable that no angel should ever feel. The Heavenly Host begins to notice. Because angels are not meant to love humans. Especially not ones whose blood is slowly becoming something monstrous. And Castiel has absolutely no idea that every day he spends falling for you… …you’re getting one step closer to becoming the very creature he was created to destroy.
