I think the mother is gaslighting and manipulating him too, they are all fucked up and he dosen't gtfo soon he is goona end up like all of them, so far his best hope is to leave with the idol who at least is not trying to manipulate him or telling him what to do, I'm sure that if he said let's leave this place together she would said yes not because she wanted to leave with him but rather she would have no reason not to go with him, at the very least each could keep each other companny while findig a reason to live
