I would be disappointed to see Kelli and Kiva fight. I like their friendship and the parallel stories they have going. While the concept of friends fighting is sometimes a juicy one, I am not for it here.
However, if they want to do it, I would make two suggestions. One, force them to fight each other over some issue. They should be reluctant to do it, but circumstances force it to occur. Perhaps the Catfight Court has a hand in forcing the two of them to fight. Two, both Kelli and Kiva should write their own account of the event, similar to what the two of them did many chapters ago.
As always, great work, Kelli. Nice to have you back.
