I'd imagine like, chihiro getting a little stressed at the karen and then running away cause he's annoyed n a little scared. then I think taka would ask the lady's name after she harasses them about being together, she says her name is karen, and then taka mistakes it for ka-ren, and says "oh that's such a sweet name!". then mondo would angrily explain while insulting the karen that her name isn't ka-ren(which means beautiful, pretty) but karen lol and then taka would take back his complement and karen would get angry.
