I really hope DPC doesn't make it so if you don't go on Jill's route, you never find out about the truth about Lynette and you figure out some half-truths that MC just accepts. And in the epilogue he goes like "I never found out about my mom's story, I wish I spent more time with Jill, maybe she would have helped me find out more". That would be pretty fucking stupid.
But you know MC is dumb enough to not realize that to find out everything about Lynette, he just has to be balls deep in Bianca and he'll be set for life - he already comes from money, Bianca is probably loaded and has a huge ass mansion, has a homie that always has his back and would kill anyone if they greeted MC the wrong way (Magnar), soon-to-be president of the best fraternity and all the chicks seem to dig him.
