A minor gripe, especially because Dean is all traumatised etc, but he doesn't even enquire how Sam might be feeling at the end - yeah, okay, people in the sub died blah blah, but, uh, did Sam not spend several hundred years in a Cage with Lucifer? He might be, I don't know, traumatised by seeing him again? Even if Dean had done a "you okay?" I would've been happy. Especially with the people pointing out how Sam was using his hands...
