I haven't played Maya and Josie's way yet, but there are really two pictures in the game files where Josie is in a red Tremolo sweater and a regular one. I used to think it depends on whether you're on the path of friendship or a relationship. But after your words. Maybe it depends on how many relationship points?
Interesting, I hadn't noticed that Josy wore the MC's old sweatshirt there sometimes.
She did so on my Josy-centric run, but did not on of my Maya-centric run (or my main run, for that matter). I can, however, get Josy to switch on my Maya-centric run if I make the following changes: follow Josy instead of Maya in Episode 5; visit Josy instead of Maya in Episode 7; have sex with Josy in the gym in Episode 8.
There might be some other minor alterations along the way, but all three of those changes seem to be necessary. Even if I slept with Josy twice three times in Episode 7, I still needed to have sex with her again in Episode 8 to trigger the red sweatshirt.
I wonder what to make of that. It's possible this is just a flavor thing, but then again it could indicate that Josy is getting closer to the MC if you focus on her hard enough. Bears watching, certainly.
You missed the biggest indicator that the Burke's were Sage's parents. The conversation at the Alpha's after Chad get's suspended from the Frat. Everyone assume's that Sage can exert influence on the faculty. There's also the name clue Jade/Sage=Green.
Oh yes, good one, I did forget that. You can also add Burke being familiar with Chad during the meeting, and Jacob warning the MC not to fuck Sage at the DIK party lest it get back to [interrupted].
I would not include Jade/Sage being associated with green to the list though; that's one of the ones I'd consider too ambiguous to count. Especially since we now know it's possible Jade didn't give Sage her name.
