Sometimes I imagine MC risking his life to save Quinn (botched drug deal?). He won't die because obviously he has plot armour, but at that point Quinn will progress in one of two ways: reform or continue down the Sith path. Her choice may depend on how the MC has previously interacted with her and what affinity path he is on.
Ya sometimes I think about different scenarios on where things could go with various character paths, and an interesting one to me would be something like what you mentioned happens, or just something where MC steps in to save Quinn from a situation, etc. and maybe she has other reasons that have led her into this life (familial dependencies, etc.) and tells MC why she does what she does and maybe that she'd love to find a way out...which leads to being on campus at DIK / HOT parties or other social gatherings where a lot of the people MC has been hanging around with, including the various LI girls, start witnessing "unusual" behavior between Quinn and MC. Where they are used to seeing Quinn's "normal" treatment of MC, they instead begin seeing her being legitimately nice to MC, using zero sarcasm and being respectful to him - how fucking weird would that be, but in a good way. Whereas in the past MC would practically work at staying as far away from her as possible in most situations, maybe the two of them are actually sitting somewhere alone just talking or dancing together, etc. - that would get the rumor mills churning. Because under such a scenario I would imagine Quinn would ask MC to keep things quiet about whatever it is he would have found out, and that would create a new "bond" between Quinn and MC - something else to piss Tommy off since he just basically ended his relationship with her - if he sees MC all of a sudden getting legitimately closer to Quinn, he'll again feel like he's being cucked by MC to a degree, which he's already feeling with regard to the DIK frat. Gonna be interesting to see how things play out.
One of the reasons I keep coming back to thinking about these angles with Quinn is because Drpinkcake has spent ~20-25 narrative hours painting a picture for us of how awful Quinn is so that all we expect is the next bad thing she's going to say or do to somebody. I just keep waiting for him to pull the rug out on that one by showing us a completely different side of her. I'll admit I could be completely off base with my thinking though so only time will tell.
Wonder what the odds are we see Vinny in this next episode...
