I so would want Dean to save Sam, and see them finally return to their old co-rependent relationship of mutual adoring brotherly love :)

I second that wholeheartedly. As long as they don't cross any extreme lines with the characters, I am fine and if these boys don't get a happy ending with each other in the end I'll beat Kripke with a stick. LOL

The show is clearly gearing up for the endgame, judging from the way the last puzzle pieces come together this season. I do think the season will probably end with some sort of confrontation between Sam and Dean. I mean, after all, what else can they do, they already killed both of them. No other way to top that! LOL
