Those wondering where Madalyn is, two things
1. Story-wise it wouldn't make sense to have Madalyn show up until around the endgame, she's already revealed herself as a demonic monster that's stealing your soul or whatnot, hard for NLT to naturally work fucking her too many times now that that's out there. Either you have the "oh man I can't help but fuck you even if I shouldn't" that's happened twice (at least) now, or you start wondering why you haven't had any side effects from it
2. Remember that we're playing an unfinished game, it only feels like she's been away for so long because we're playing small pieces two weeks apart. You play the game start to finish and it won't feel like nearly as long
