.I also think seeing his Sammy taken over by Lucifer absolutely killed him—the tears in Dean’s eyes made me extremely emotional.

He was all over the place in this episode, what with seeing how his future self turned out, the world and everything else. But seeing Sam like that really pushed him over. It was emotional and I loved it because I think it put things back into perspective for him as opposed to how he was w/Sam at the beginning-letting him deal w'the knowledge that he was Lucifer's vessel by himself.

:D I loved Castiel. I couldn't stop laughing when how after Dean hung up on him, he just continued to stand on the side of the road.
