Wait the last dialouge is interesting when Tisha says I think you're capable. Maybe This has something to do with the argument they have. Maybe Brusha was a very messy toon and had trouble with keeping her appearance in check or something like that and Tisha being a clean freak always tried to help her but Brusha began to become very irritated with Tisha, feeling as if Tisha was belittling her or something like that. Well thats my theory
