Dean looked worriedly down at him, but nodded anyway. He tilted Cas in such a way to get his hair wet and then started in lathering it. “Talk to me then?” This didn’t feel good. He wanted to fix it.
Cas' eyes drifted closed again at the feeling of fingers rubbing against his scalp. He could do this all day, every day, and not regret it.
Still, he knew he should say something. Knew that there were a lot of things he should be saying. He licked his lower lip, still torn but not bleeding. "I -- it was. A lot of emotion." Cas always kind of needed to be coaxed into speaking, but he really was trying.
Dean worked his fingers expertly into Castiel’s hair, making sure he was clean and as relaxed as he could be. “Are we okay?” he asked. That was the most important thing. Everything else he could deal with so long as there still was a we to make happen.
Cas drew his lips into a thin line and peeked up at Dean, looking concerned and solemn and probably a bit ridiculous considering soapy hair. "We are okay," he responded, as if he knew exactly what Dean was thinking, and wanted to tear that concern away as quickly as possible. "You are my husband, and I love you."
He glanced back down at the water, fingers resting on his knees. "It was just a frightening amount to feel, Dean. Too many contradictions."
Dean nodded, and tilted Cas back again to wash his hair out. He honestly hadn’t known he’d had all that in him, that his anger catching him would turn him into that. He didn’t particularly like it and definitely wasn’t proud of himself for it, but he wasn’t going to belabor the point. Not now, not with Cas. Hair rinsed, Dean set about conditioning it.
“I know,” he said softly. “You did well, though.” And, because he really couldn’t stop himself, he added, “I’m sorry I flew off the handle like that. I’ll try not to let it happen again.” Because now, in hindsight, things really did seem pretty clear. Cas was being Cas and Dean had seen the kid’s rear enough to know that he wouldn’t want to be wearing pants either. They were just talking. But hey, now maybe the kid would actually look at him rather than spending his time mooning over his husband.
