yes!! although i imagine there's some tension for chelsea too if kalia liked elisabeth since, by default, chelsea didn't like her, trust her, want her anywhere near theo, etc. she was pleasant and friendly because she's not 14, but when they separated and filed for divorce she instantly went into "WHY CAN'T SHE JUST LEAVE HIM ALONE ALREADY" mode. mostly because she's probably hyper-protective of the whole family and knows it's hard on him.
