there was a lot of pressure from her parents because they could see they weren't 100% healthy for each other, and she's very much in a weird limbo of like, "wait, what did i just do?" with a lot of regret rolling around. they're still in love with each other - which is why she "can't just leave him alone" - and so it depends on the day whether they're on good terms or bad, but ellie would never, ever put anyone else in the middle of that. i could see her really adoring kalia, kind of seeing her like a little sister? especially since she would've been so young when she and theo started dating! so if kalia was receptive to it, she'd very much still want to hang out with her and be there for her and everything, and she and ~giovana are still close. she's very respectful of the fact that theo is her brother, so she'd never bring him up/discuss anything about the divorce if kalia didn't bring it up first.
