Rebels:
You and Katelyn have grown a bond. So when she calls you to come over ASAP you figure "oh no she's in trouble" turns out her and her sister Kathryn gotten in a fight, and this time one of them got violent.

Royals:
Kathryn text you "Please come over, I need therapy" which is code for "get me away from Katelyn" and man. It's bad this time
