What do you hope for in the rest of season 6?

Good question. I really hoep Sam's alright, and that he's pretty much back to his old self, although we might have a few therapy sessions of him talking with Dean about Hell if the "wall" doesn't hold. In a way I hope the "wall" in Sam's mind doesn't hold, because it'll be interesting to see what Sam remembers and shares with Dean about it, and how he handles it in comparison to his brother.
As for the rest? I have no idea :S BUT i do have faith in Sera and the rest of the team to keep it going well and make the season finish with a bang, be it the last ever episode or just the last one of Season 6!
Roll on Season 7! :D

i hope for alot of castiel! lots and lots!

well have no idea what i wont for Sam - i mean hes got his soul back - but now hes gona have 0 powers - yeah its good thing but how is he gona be - thats the most looking forword too seeing him in this how new life - but i wont bro LOVE back 2

I hope Michael returns in John's body and Dean says yes.

I'd like to see Dean's bad boy/hero self re-emerge and I would like to him to accept that he is not a killer because he kills evil things. He is a hero.
