Not much of one? "It still worked, didn't it? I mean..." Kotetsu spread his hands, smiling. If it was a little weak, it could be forgiven since Ryuichi wasn't looking up at him at all. "I don't feel like killing people now."

Just... tired and sad and cold sick guilt curling in the bottom of his ribcage, but that'd go away eventually, because he knew now, and he wouldn't do it again. Wouldn't pin Ryuichi that way again if he could help it.

Time to change the subject. "Let's go get something to eat," he suggested. "My treat?" Not that Ryuichi needed it, in all honesty, but maybe it'd reset everything to the way it was before.
