Jesus, Dean was crying. Sam stared at him, not really sure where to start, how to approach it, so he pretended that he didn't notice, that the water crashing down on them both was hiding some of it. But as much as he lied to himself about that, Dean's voice goddamn cracked as he spoke. Lucifer had broken in here, past all their spells, it was true--and it was true that it was Sam's fault too. He'd given him the damn ticket in through the front door, and now he could do anything he wanted to Dean, no matter where they hid.

He grimaced.

"We still have the Enochian seals on our ribs. We can abandon the bunker, Dean. Maybe it won't be as easy for us to fight Amara from here, but so long as he can't get to you..." He gave his head a rough shake, and reached his hand up to Dean's shoulder, squeezing it firmly.

"Cas won't be able to forgive himself unless we try, right? We have to."
