Kate Austen (Lost)

Triggering (part of canon): Kate blew up her house with her mother's husband Wayne sleeping there; he was physically abusive to her mother and was starting to be gross with Kate. She only killed him, though, after finding him he was her biological father, which left Kate horrified in many ways. Her mother took his side and called the cops on her twice, even when Kate visited her at the hospital after she got sick. We don't know if Wayne was making passes at Kate all the time, but it's tagged noncon references just to be safe and it's easy to assume he WAS, because Kate wasn't at all surprised when he was being suggestive to her while drunk, so considering this is her bio father we are talking about, you decide if you can handle such references. So: noncon references tw, alcoholism tw (her father)

very short for people who want a recap or can't read details now:

-she's not IN love with Jack, though her actions before leaving the island are nearly the same (except she won't date him later), she kisses him while having her crisis (Sawyer being 'possessed' by Wayne) and still cares about him. But in s3 she doesn't get jealous of Juliette: after their kiss and accidentally leading him on, she's simply riddled with guilt for messing with Jack's head and wishes she could love him back. THEN she still jumps Sawyer in his tent because she needs to make herself feel better.
Sawyer can think she jumped him because she saw them having dinner together, though, if we are writing them in a shippy way. So it can be a fun discussion later.

-She loves Sawyer but she's nearly as messy as in canon. We can decide if things go differently when it's time to go home/jump in the past, but after her pregnancy scare things can still go similarly and she'll return to camp (minus the slap, I'm guessing, because by then Sawyer would know she's not going to run to Jack specifically, unless he pokes at the fact that she wants to want him because it's seemingly safer that way).

-by default if she's rescued and goes home through the show like in canon, she'll stay single. Your Jack muse can feel however he wants for her. She's focused on Aaron and trying to rebuild her life. However, those seasons of Lost can be rewritten however we please.

-I do say I ship her with Sayid too, so it depends on whether you want to try to build that up instead, but only if you want to subject him to the toxicity of trying to be with Kate, because she's too scared of being just like her parents and trying to push him away.

-Her fear of becoming like either of her biological parents exists regardless of Sawyer, and will follow her in romantic & familial & strong platonic relationships in this order: she doesn't want to be either of her biological parents. Kate's afraid she'll be a terrible mother too. Before Aaron, pregnancy-scares are legit pregnancy-terrors.

-because she's not as close to Jack and actually puts distance between them in season 3, she gets closer to others after being even more of an outcast than in canon because she needs some kind of connection. She's more "open" (relatively so, it's still Kate and I'll still write her pushing people away). This is the only way I can have Kate realistically become closer to other people, not having Jack to rely on as much as she does in canon.

-Her traumatic past won't ever go away, she won't magically heal with 'love', she needs to have innocent secrets and plan Bs and probably money hidden somewhere in case she needs to escape even if she's in a secure relationship.
