I think I know what the cliffhanger of this episode is going to involve... probably Castiel's fate (if it isn't already known earlier in the episode) and all these souls escaping Purgatory. I wonder if it's going to be like the season 2 finale when Jake opened the Devil's Gate and all those demons escaped out into our world. I'm thinking that might be (at least part of) what season 7 is going to involve. As for Sam's wall, I've heard something about it breaking at the "top of the episode" and I would think and hope that he's not going to stay catatonic or whatever through the end of it. And if he is, they damn well better fix him by the start of season 7. I think it would be angst overload if we had to find out what Cas' fate was or deal with whatever he does, AND anything escaping Purgatory, AND then Damaged!Sam on top of it.
But I guess we will see.
Oh! And doesn't Sam look like a Puppy again in this pic?? ♥ ♥
