[ There's no fighting the fact he's angry, doing nothing to stop Dean from dragging him in by the front of his shirt and shaking him. Castiel's eyes are on his face, some attempt to decipher what it is he sees and what he hears.

And it's not as if Castiel takes it lightly. Dying isn't pleasant and the aftermath of it is worse than its cause, but having this here, having that audible evidence thrust in his face the way it is-- He has to consider what it's really supposed to mean. So he doesn't want him to die, but he would sacrifice himself instead? The hypocrisy is outstanding, and his own anger reflects back, gripping Dean's wrist and squeezing it hard. ]

[ Again and again and again. ]

We might not have another chance if we continue to wait.
