What planet do you come from?
(in a universe where lust-inducing products are a 'thing' and have seeded the local supply of potable water)
Do note that your own character's mother is in an odd spiral at the time that he starts trying to keep tabs on what she's getting up to, and has her own (sex) plotline with him. Also note that the main character's mother from the previous game was much similar. The key difference is Naomi not being obstinate about "But I shouldn't..." and
also not being a hypocrite when a situation that applies to her happens to apply to her own adopted daughter.
... Remider, if you were under some bizarro alternate take; this is not a game about
morals or "upstanding behavior" in the face of lust-inducing factors, or, honestly, choice. Allegedly, a decent portion of the game involves happening across opportunities to get (your character's) dick wet. What it sounds like, is that you're complaining you
don't have to jump through multiple hoops for her to be down to fuck. In a game where there's an entire function dedicated to obtaining sex positions particular to individuals, making your home of residence fancy as fuck, and then inviting those that are fond of you over for a romp in the bedroom.
So pardon me if your dislike of a character
not being heavily involved with other plots sounds odd to me, but you do you?
Because there is no way her or her simpleton daughter have nothing to do with plot where its at least hinted her daughter is something more.
... You mean the daughter that's steeped in the production and testing of the aforementioned lust products? That one? I don't recall
claiming either of them had "nothing to do with plot," just that they're (to my recollection) part of the dwindling number that aren't involved directly with either of the more dangerous cast members, and how that, specifically, is an odd thing to claim makes Naomi worthy of disdain.
