Keir Winchester is back... where he's been, well, let's just say he's not the same kid who died. Keir changed. There's no doubt in that as his actions take over from his mentality. He's brought back with his brother's mother, a gift from Amara to his eldest brother, Dean. Keir Winchester was in the land of monsters, Purgatory, between Heaven and Hell. He's fought for his life the past few years, and now that's he's alive again, he doesn't know how to adjust. He truly did turn monstrous.
