This is totally what's going to happen...
I can't wait for Supernatural to come back on!! Sam's going to be like "WTF! Ma brover's not dead!" and Dean will be like "Holy shit! Imma demon!" and then Cas will show up and try to beat the shit out of Dean because he'll think that a demon possessed the dead body of the human he secretly loves!!!!
I really really really want this to happen!!
And then Benny will show back up and be like "It's been a while, brother... The demon eyes suit you (or something sarcastic like that)." And this'll make Cas more angry about the whole demon thing, plus he'll be jealous.
And in the background, Sam and Gabe are makin' out. Crowley sais something funny about squirrels and moosen (get the reference?). Oh, and Balthazar will be there too. I liked him.
Okay, think that's it... yup. :D
