I guess the biggest diff with Setsuna and Kamui's relationship now is that he knows Kamui has emo. :( Not only that but Kamui has emo Setsuna knows all too well now. So he's all about helping Kamui get through it, and in a away it also helps Setsuna deal with his own problems. Setsuna still loves teasing the hell out of Kamui, but there's a bit more understanding this time around. They can Messiah bond and they don't even know it. XD I need to figure out a way for this to happen sometime.
