So, it seems that I may have watched
the new promo for SPN Season 5. (It is spoilery) ETA: not the NEW new promo, the other new promo. Haha, yes, I know, that's not helpful.
Okay, somebody needs to capslock and flail and be terrified with me in the comments.
ETA: spoilers in the comments (please confine spoilers to things revealed only in this promo)
