That would mean she's moving back up, as they're still on the entry level. 

By my read of it, the hooded gentleman that they've engaged was leading the contingent that came up through the right stairwell (assumedly in the wake of Mari shredding the initial wave that came up), and forced Fanilly down the left. Gerard being a few seconds ahead of her group on that path, I can only imagine he's running into the skeletons as well, so I'll be looking to engage the fella in full harness when I next post. I think that would mean we're (Gerard, Fanilly, whomever's with her) on that same lower level as Tyaethe and the Barukstaedian, albeit on the far side of the lower chamber.

I think that's everyone accounted for, save maybe Mari if she hasn't continued to to that second chamber. It's definitely gotten pretty touch-and-go to keep track of.
