-This is a very interesting conversation. We know that Castiel considers Sam his friend - yet, is he really dissuading Dean because he fears for Sam's wellbeing, or is he trying to stop Dean from interfering with his and Crowley's plans? For that matter, if he IS truly concerned for Sam, is it not better to end Sam's eternal torment in hell for a non-eternal torment on earth? I mean, even if he were locked inside himself for the rest of his life, at least he wouldn't still be in the cage for eternity. I'm just sure I really see the logic here. Is having a sociopathic non-Sam while Sam's soul screams in the cage somehow better than caring for a hell-broken Sam?

After we found out that Castiel raised Sam, I went on the assumption that he didn't want Sam's soul back in case Sam WASN'T left catatonic or a babbling idiot. I always assumed that Cas was afraid that Sam's soul would know that his body was rescued by an angel (and what other angel would bother to try) or that either Lucifer or Michael identified Castiel during the rescue. (Here I'm assuming that Castiel rescued Sam in his form the size of the Chrysler building and being pure energy, not in Jimmy Novack's vessel). I think Cas was trying to maintain his lie that he had nothing to do with rescuing Sam and Sam's soul had the ability to blow that lie out of the water.
