My predictions for ep4:
Derek's door - full break down of Maya and Josy's relationship, first going through it with Derek, and then later with the girls themselves. Maybe this leads to something with them, or one of them, or going his own way.
Sage's door - I think this will involve HOT drama. Dawe wants Quinn to step up and kick Sage out. Sage will turn to MC for support. But, this might be conflicted if the MC has dipped into the food menu side of things. Anyway, I think this one will focus on Dawe's/Quinn's stuff, and maybe the whole prostitution thing will come out, and maybe Sage will have problems with it, but might be forced out anyway. The MC might be able to join Quinn's side, or support Sage. I dunno.
Bella's door - this'll probably revolve around Bella's guilt around what she's been doing. But, further, maybe will allow us to find out what kinds of stuff Bella (and Jill) have going on. I think Jill's campaign is probably something to do with mental health, and this comes from wanting to help Bella with her "delusions", lets say. It could be something like that. I dunno.
Anyway, I like that the episode might split off to tell different aspects to things. You get to play them all to see different sides of the characters. Let's hope he can fit it all in around the rest of the Hell Week stuff.
