I'll try, I use very few turns of phrase like that when I write, but I'm sure she'll make failed attempts at them whenever I can find one available. XD Or instead of "What comes around, goes around" it'll be more like "What comes here... goes there? No, that's... wrong... Uhm..." XD "How you say... a cat is holding my tongue! Yes."

EDIT: I think we could just assume, or you could tell Genkai or the others to assume she translated, if you prefer ^^" So we don't clog.
