Sam just let Dean stand still, working his way through cleaning off the come and the few splashes of blood. Dean was mostly bruised, which meant that most of his pain was inside, rather than out. Not inside physically. Sam didn't know how to deal with that, how to cope with it. Dean was meant to be the strong one, but when things like this happened he internalized, and bad things usually just got worse. Coping wasn't something that Dean did well.

So he went to town with cleaning him, scrubbing to try and get some of the feel of the archangel off him. Cas had been his friend, and Sam wasn't blind, he knew there was something there. Whether or not they'd ever been intimate or not he had no idea. He hoped they had. God... God, if Lucifer had ruined that for them...

And Sam couldn't help blaming himself. The fact was, if he hadn't gone down there, Dean and Cas would never have followed him.

Finally he reached forward and shut off the water, stepping out of the shower to drag down a towel and throwing it across Dean's shoulders.

"Come on. Dry off and get into some dry clothes, we're going to go for a drive."
