I mean, yeah, it's a story so to a certain extent the plot is on rails, but MC has had opportunities to do things which could mitigate or affect the end result, and while we haven't yet seen that have a payoff, I would expect that those decisions will have an impact when things start to come to a head.
I think pretty much 100% there's gonna be a scene in the future where Quinn wants Maya to do something that either itself is a problem or would compromise her in a way that Quinn would gain leverage over her, and Maya will hesitate and not agree to do it or not go to the place in question if the MC warned her, and will go and get entangled in the problem if he didn't.
Yeah, man, that's all he knows at that point. And neither he nor Maya have any reason to believe that the entire HOTs sorority is compromised, in fact, they have a bunch of reasons to think otherwise. I'm really curious which event in the story you think should be MC's huge red flag that he should insist that Maya no longer associate with the HOTs or try to join, or involve the authorities. And are you sure you believe that Maya would even believe him? She has some powerful motivations for not wanting to.
