I don't think it's likely we'll end up killing her unless one of a couple situations arise, like maybe she asks us to "talk in private" because Logan dumped her for us and she tries attacking us while spouting some BS about Logan coming back to her if we die, or she turns into one of the swamp werewolves but as a human somehow and getting rid of her saves the werewolves. and I think imprisonment is just as unlikely since she hasn't really broken any laws that are in game as far as I'm aware, she's done some... very morally wrong things sure but nothing illegal in game from what I know. unless you mean we have her in our prison thingy at the hut so we can try to bring her mind back, in that case it might happen, we did do it for Bernard/Logan depending on who you saved at the first attack.
