Aside from Naruto and Katara meeting in person (and maybe having an adventure or battle together) at some point and hanging out I also still want Cassie to meet Naruto so they can be blond blue eyed good guy derps together. >D I think they'd totally hit it off. Cassie will also be looking for people she can have friendly matches with- actual hand to hand not just Pokemon battles -if that might be a thing if they get along?
