Cutter would find the fight training bit interesting and could relate to her view on fighting. You know, if he could ever manage to talk to her because she has this thing where she's a chick and he finds that terribly hard to work around. Unless he's drunk which practically happens every night. So. They're bound to interact sooner or later since they work at the same show and it will most likely be awkward.
Frankie... with him I feel it depends on how people behave the first time he meets them, but he will definitely find her interesting if she's in a bitchier mood. He might also hang out to watch her fight because it doesn't really fit into his understanding of the world in general, he always thinks men are supposed to do that and women... don't. He just doesn't get people all too well.
Ella will love her kimonos. She likes pretty things. Remind me to never do this right after breakfast, not my most creative time of day. They could get along well,and they couldn't. WIDE OPEN here.
