OK, I think it's the top of the round again. Marlowe has been released by the bug, but is still adjacent to it. I'm going to say that as long as Marlowe doesn't resist, then Cade can treat him like an object for the purposes of picking him up and moving with him.
Those of you above ground see a score of demons coming into view around the perimeter of your positions, including a glabrezu and a nalfeshnee. The psurlon also informs you that there are even more demons that are sneaking about but not immediately visible (make Spot checks if you want).
The portal is still underground, but visible if you're nearby. It was in a fairly sizable underground chamber (which you have not explored yet), the ceiling of which was destroyed by your digging and the subsequent cave-in. From any moderate distance, only the soft glow of it is noticeable, but not the portal itself.
