Laurelin I appreciate you coming up with new things to talk about

I don't think it'll be a Cathy flashback though as she isn't important enough (especially for those on the M&J path) and would be another sidetrack from the main story.
This game needs to pick up the pace a bit and I'd rather see certain arcs moving forward rather than another diversion.
Thus, what I would like to see open the episode (this more a wish than a prediction) is what was transpiring while MC was giving his speech at the DIK Mansion; i.e. it picks up from this:
and we see the call happening. This obviously won't be a flashback but a 3rd party view of events similar to the Jade/Steven picture throwing scene.
Unless we get resolution of bella’s Locked door, in which case there might be justification for another flashback, I’d prefer we have an episode without flashbacks.
I agree and I think there's a better chance of this happening in Ep.6 (possibly very the near end leading to a cliffhanger) than most people think. Why? Because the last line of
both Jill and Bella's bio now refer to Bella's "privacy."
As we know, these bios change and evolve every chapter, it would be absolutely bizarre to have that line there and then completely ignore it and just put something new there at the end of Ep.6. Maybe not a full reveal, but pretty sure there'll be some "prying"

and I'm optimistic that we'll be making headway with Bella's trauma/secret arc (at last).
