- If you drink with her during the movie, you miss out on all the fun that night but Sage isn't phased.
- If you don't hold her hand, you miss out on all the fun that night and Sage gets pissed at you (-1 RP).
- If you hold her hand but don't take it further, you still miss out on the fun but Sage is fine about it.
- If you take it further, good things happen:
- Be a dumbass when brushing your teeth (Sage likes that +1 RP)
- Make sure you grab her ass in the bathroom or she'll accuse you of being gay, and basically why wouldn't you grab her ass?
- Then there's a whole lot of fucking, probably the most fun sex scene so far. I loved all that shit about her trying to be quiet and then not giving a fuck (while most definitely "giving a fuck").
But that's all there is to it. There are no further repercussions no matter how the movie night plays out.
The next time you deal with Sage is in Tybalt's room at the prep's party, and as long as the mc has been teaching her guitar and he didn't reject her back in episode 3 (when he plays guitar for her and she's sitting behind him), there will be fucking.
Sage is actually a pretty easy character to get with. Even if you constantly reject her all along, in episode 7, after she breaks up with Chad the mc can still fuck her all over the HOTs backyard and her room (assuming he doesn't run out of stamina because he's been on a fucking spree during the party - like why would he ever do that?

).
