I wonder if Episode 7 will have any scenes between MC and Sage like they had in the swimming pool, where Sage shows a willingness to have an actual relationship with MC, rather than just fuck buddies.
She shoots down the MC's first two attempts at a relationship (when she's jacking him off during the guitar lesson and while having coffee in the HOT kitchen). After the pool conversation, MC doesn't try to push for "more than fuck buddies" anymore, and their relationship starts to evolve naturally, with MC becoming Sage's genuine friend and someone she can open up to.
I like the little look Sage has as the two cuddle in her bed while she's sick, after MC admits that he's never talked about his views on his mom's death and his birthday with anyone before. She opens her eyes, a worried look on her face, briefly aware that the relationship is deepening.
I also wonder if any sort of "artificial roadblocks" will be thrown up by DPC to prevent a Sage/MC relationship from developing too fast. I.E. MC gives Sage the same "I'm already falling for you" speech he can potentially give Jill on their picnic date, but instead of kissing MC passionately and letting him grope her, the more cynical Sage freaks out and harshly points out they've barely known each other for a month and she's just getting over a nasty breakup.
Or Sage discovers that MC was aware of Quinn's menu and is furious that he never told her (Sage), or (more realistically) Sage admits she's open to a relationship with MC, but given her recent breakup and the fact MC fucks anything that moves, she insists on taking things slow for the time being.
As far as Sage and Jill both graduating, I could see MC following in his mother's footsteps and ditching college to be with Sage/Jill ("I don't have to graduate from B&R, there are plenty of colleges I could get into. I just want to be with you.")
