I think it's better to remove the whole room mate thing altogether, the last game they made had the same issue, with landlord sounding and behaving like a mother and the Roommate basically being a sister in the Dialogue, so they changed it so it is exactly that and i think it was a lot better off for it, i would suggest the same thing here. and no, I'm not into incest either, but in the end i wouldn't want to force an entire re write on the developer
