Jack: You don't know anything about Dean.

Michael: I'm in his head... literally. I know everything. Like, I know how sad he was when you died... on the outside. On the inside, well, it's not that he was happy... he just didn't care. 'Cause you're not Sam. You're not Cas. You're a new burden that he was handed. You're a weak, helpless thing. You think that they care about you, love you? You're a job, a job none of them wanted.
