For the Wincestiel BigBang Challenge: Castiel is the newest agent sent by E.D.E.N. to hunt down the two rogue hybrids, Sam and Dean Winchester. But there may be more to their story than what a manilla folder will tell him, if he stops shooting at them long enough to listen.

Dean has a gift – he can see things. Things that others wouldn't see, motive and calm control between the splatters of blood and fractured mirrors. He solves crimes others simply can't. When bodies are piling up all around him, Dean starts to feel as though he's drowning in it, falling under the weight of his own helpless observations, until he finds something unbreakable.

Skinwalker!Dean/Hunter!Cas AU, set in the spirit of S6. For four years Castiel has been hunting this mutt down, and now he's finally caught him, and he has a few questions that he needs answers to, and he'll stop at nothing to get them. Non-con inside.
