"Okay, we're definitely actually hearing that."
"Here they come." Omiko informs the two henchmen she assigned to watching the prisoners. "Open fire as soon as they come through the dungeon door."

One henchman is kind of near the door, the other is at the end of the hall. Omiko herself is lounging right outside Ilpholin's cell (which is the first one on the left). Which as far as we know, contains one(1) unconscious Ilpholin hooked up to various IVs and medical monitors, just in case. There's also Zefir's torture devices shoved over to the other side of the cell. She's not considered much of an escape risk, since she hasn't moved under her own power in quite a while.

And there's two other prisoners in the cells, which I think Omiko put there just in hopes of complicating things.
On the right there's a cell with a striped catgirl, and further down on the left we've got this grizzled sea captain.
