I will continue to hope that there will more scenes with her. It can't end like this, with just one time.
She surprisingly didn't hit it off with a lot of people, of course most people were there for Nicole, but I thought that was possibly the best threesome of the game so far, including ep7.
I also think DPC is scaling back with Nicole (notice she didn't even rate a mention in ep7).
My theory is Nicole and the mc's relationship has moved very fast and any further scenes with her will take the relationship to a level possibly too far for a non-LI character.
Nicole is definitely looking for a long-term relationship, and she thinks she's found someone quite special in the mc, and in all his words so far, the mc see's himself as someone that could be serious with her. But there's no fucking way the game's ready for him to be meeting her son and getting all serious with Nicole, he's got too much main LI shit to deal with, hence the brakes have been artificially applied (i.e. no more Nicole scenes for a bit).
And if there's no Nicole, it's likely there's no Sandy (it was one thing for Nicole to share the mc with Sandy while she was also part of it, but I doubt she'd be giving Sandy the mc's number).
Is there a theory whose Sandy is the mother/sister/daughter? As I understand it, she is done with striptease and therefore we can see her at college instead of Katie.
You mean Cathy? I think the theory was Nora may show up as a teacher, and maybe she was Maya's mom (just a joke I think, not a serious theory).
Also I don't think people showed enough interest in Sandy to suggest she's anyone's family.
