Castiel looks at Dean and the hurt his words cause is evident on his face. It flickers across his eyes and his expression in real time because this is not the failed God that Castiel had become before, full of power without any sense of right or wrong, twisted with the souls of purgatory. No, this is Castiel, the angel who Dean taught to feel emotion, to understand the plight of the puny humans, the beauty of free will. He knows he absolutely deserves Dean's doubt, but one thing he does know is that he did not choose this for Dean and Sam.

"I was placed in charge of heaven, long after Sam took over hell. I didn't choose this for you Dean. You or Sam. As for myself ... it's not like before. Your brother would never allow that to transpire."
