Sam. Shit, Sam. He truly doesn't believe Dean can do the job. Oh, Sam. And OMFG! Drinking demon's blood to become more demonic. EEE! That makes so much sense.

John Winchester didn't break for a hundred years. Oh, Dean.

Dean doing the torture was all sort of horrifying and awesome at the same time.

Dean brought about the Apocalypse. Oh. The first seal. Oh, Dean.

Sam. OMFG! Sam. That kind of power is terrifying and dangerous. Also, Castiel SAW the WHOLE thing. WHAT? OMFG! What must he be thinking?

Also, Anna, you are so very fucking awesome. So awesome. Just one question, how powerful is Anna?

Castiel! Oh, Castiel who has emotions now!

Anna! OMFG! Anna! Just so very awesome. SO VERY AWESOME!

Castiel is perfectly truthful to Dean; their fates rest with Dean. And Dean, and Dean can't do it, he just can't. Oh, Dean.

D: Find someone else. It's not me.

OMFG! CASTIEL must be thinking about SAM! OMFG!

There will be more coherent thoughts sometime tomorrow when I can think.

ETA: As a result of this episode I've come to the realisation that I will need to compeltely rework my bigbang. Bother.
