Dean closes his eyes, dragging a hand through his hair, and has to listen, because there's nothing else to do. Castiel's right - if that's how things went down, there isn't anything to do about it, not really. Which means Cas and Sammy did the best they could with what they had, which isn't...much, honestly.
