if you mean a confrontation it's not in game yet (uncertain if it will be added either cause she might just be.... well literally a mindless slut for the Werewolves and stuff. maybe we'll get him talking to her as a weird form of goodbye for him, maybe we won't idk.) but if you mean him learning where she is, I think i remember him mentioning he could smell her while we were in the werewolves den before we fight the Alpha as Logan so he prolly already knows where she is.
I believe it's too late for her. I remind you, she is basically mindless. AND what's worse IF she's not this could really mess up relationship with Logan. I don't know, and I doubt that if he would want to have anything to do with her at this point ESPECIALLY IF he already have feelings with your character.
Although, I think it MIGHT be planned to make Logan join her at some point in his botton route especially after his second scene at bandit camp. That's not what are you asking but I think that's the closest to their direct interaction.
no idea why but I feel like we will bring her back, I have no idea how but I just feel like we'll find a way. maybe we'll use the cleansing water from the lizard tribe? it does restore our sanity stat so maybe it could have a similar effect on her? and on the possibility of her messing our relationship with Logan up, I think that's only gonna happen if we miss a heart with him. maybe 2 heart Logan will sway between going back to her or staying with us, but I think 3 heart is gonna dump her for us after saying some final words or maybe telling her how badly she hurt him.
and I feel like this is kinda what the bottom route has been leading too the whole time. like his wife becomes a super whore and disappears with wolves and werewolves, then her husband happens to encounter bandits who cause him to become a super whore like she did and he doesn't disappear for sex with werewolves like she did? seems unlikely. but if not that maybe he could meet a wererat and become like a replacement for Tao to the rat king?
I mean, at this point we know that Logan know that Selena IS there. If he wanted to he would already go to her. I just want to remind you his anger and disgust when we tell him full truth about her and pendant that we found. I don't think bringing her back would change anything in his mind. He is stubborn enough to not change his mind about her. We are a main character, of course he will forgive us if we sexed someone else, but will be impressed if we didn't and "waited for him". That's not the case for Selena. Unlike us, she is no fighter, didn't defeat bandits, didn't help with werewolves, wasn't with him at his lowest moment when he was cursed. As far as I see, he moved on and don't care much about her anymore since she was disgusting enough to let her just be fucked by werewolves and wolves before.
I understand and both, combination of sanity potions and cleansing water maybe, MAYBE could do the trick, but at this point, her mind maybe could have been restored, but Logan's mind is already set. I see this that at best she will at such situation have to live at the tavern being a maid or waitress or to live with Rose.
About hearts with Logan, I don't think it is relevant at all. Firstly, because coloured decisions that bears relevance to the game are set before and those if I remember are not coloured (telling him truth or hiding details) it would mean that would make no difference. Secondly, hearts matter only in terms of characters interest in you, their demeanor, reactions, but not their relations with other characters.
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.
