I'd kinda be surprised if her issue wasn't brought up in the epilogue at all. The notes say that you get a bunch of letters and check in with a bunch of the NPCs from the game so it wouldn't be a stretch to say that the Gondians or Dammon show up with a solution.
Edit: Really that would check all of the boxes. It'd be a solution that we worked for based on what we did in the game, it wouldn't undermine the Avernus decision since its a whole six months later, and it'd work the breadcrumbs together into a believable path. Honestly it'd be kinda strange if it WASN'T addressed, and would just be another story hole.
