Well, I'd rather not know any of that to be honest. But it's there, I'm old and not young, dumb and full of cum, that it will bother me. I mean I've seen posts from dumbasses that get upset that their moms aren't virgins. Like they want to be born from immaculate conception or some shit. I think because I'm old, I accept the fact that everyone has a past, a backstory. But do I want to know it? No. But if it's there, I accept it. I just don't want to see flashbacks of it, nor do I need the girl or the dev to give me an entire essay about it.
If Quinn's past fuck buddy does matter, it'll rear it's ugly face with the MC getting shot if and when Vinny finds out. Until then, it doesn't matter if they were or weren't fucking.
