Dean Winchester knew that he was not fit to be Heaven’s Righteous Man, or their Michael’s true vessel, or anything else, for that matter. He wasn’t fit to go hunting with his estranged brother, Sam - a man he hadn’t seen in fifteen years. And he really wasn’t fit to be having discussions on the meaning of love and free will with an angel. All he wanted to do was stay dead, or be given the space he needed to grieve. But luck wasn’t on Dean Winchesters’ side.
AU in which Sonny sent John away at Dean’s request. Dean took Robin to the dance that night, and years later he married her. Only, the course of love never does run smooth and sometimes life steps in. Robin got sick, and she was dying, so Dean did the only thing he knew how to do - sell his soul, getting five years for his trouble. A month after his deal came due, Robin passed away. Three months later, Dean woke up in the cemetery he’d been buried in. Lost and confused, Dean is told he’s supposed to stop the apocalypse.
