The way Ep 10 goes makes me think there are stuffs that won't match what we think, and the story will go in a different direction from what we expect.
The theory that Jill's family knows Lynette and that will somehow matter to the main story. Amelia hears Neil's name and the meeting goes on as if nothing happens. Also, this meeting will only happen on Jill's path too. For something so close & important to MC's story this detail seems too path-specific. My guess is that with this, DPC debunks a lot of theories about Lynette's association with the Royce family. They just probably don't know her.
Theories about why James left. Bella opens up to MC in Ep 10 about her past, but only if MC follows her path too. Therefore I don't think her story will be woven into the main story. James coming back will definitely matter a lot to Bella & MC, but it definitely won't make things as dire and horrifying as we think. Coupled with Riona kidnapped, and Patrick being a controlling asshole, there's no reason to make James another dangerous villain.
For the story to reveal these kinds of details only on path-specific plays, and force Maya's story down the player's throat, with the whole gang showing up like the Avengers, I think DPC is veering away from dropping every backstory and tragedy on the player's head, mainly because there's nothing too important about them in the first place, and also it takes away the gravity of the main drama which is Maya. I have not chosen Maya in any run ever, and this new episode fully convinces me to never do so. The writing is excellent, but I just don't like her.
