This is it, spoiler lovers. The big one, the culmination of the entire season. And it looks like Castiel and Bobby have another bullseye on their backs: we're losing a "beloved character." Part of me doesn't even want to see this episode; I'm afraid of what's going to happen.
THE APOCALYPSE – The entire season has been leading up to this showdown between good and evil. With the Apocalypse looming, Sam (Jared Padalecki) and Dean (Jensen Ackles) realize they are out of options and make heart-breaking decisions that will change their lives forever. A beloved character is killed. Posted on KSiteTV. Steve Boyum directed the episode with teleplay by Eric Kripke and story by Eric Gewitz (#522).
