It sure would! I think they would probably get along so I am up for them meeting once Kuzuryuu gets to Goldenrod. :3 I'll keep an eye out for posts from Rude. :3

as for Leon...man, I have no idea. I guess just play it by ear and see how it goes? It'll probably be a while before they meet again anyway and though he's still bitter about it, Kuzuryuu is mostly calmed down so there's that. And as long as Leon doesn't make a habit of insulting him, they should honestly be fine. (though speaking of Leon I'd be okay with threading him and John more as well if you'd like.)
