Predictions for the sixth season of supernatural?

Tweet

How do you think this season is going? I' am really loving the different style and the new season plot. The introduction of Samuel was so unexpected, but I think theirs more to him than meets the eye.Maybe in this season, Gabriel is stopped? Crowley dies? I have no clue, but I seriously hope Castiel plays a big part, he is so cool. So what do you think will happen at the conclusion of the season? Something tells me it will involve Samuel and what brought him back...
