Elia felt sorry for Kaelyn when the Starks first showed up, and she still sort of does... but she offered Kaelyn help with settling in and Kaelyn basically bit her head off. She may or may not have insinuated Elia and all Dornish are whorish pit vipers. Elia forgave her, because she thinks Kaelyn's just too stupid to know better. They don't talk much.
