Umm what you said to that one anon about Sam dying in episode 21, were you serious? Are there spoilers to point to Sam dying in episode 21 or was that a joke? I don't think they would kill one of the brothers before the season finale.
Oh yeah. Sam is totally gonna die in 21. 22 will be only Dean crying for 43 minutes and Mr. Ketch smoldering at he camera.
Yes it was a joke.
