Philippe decides to sit somewhere.

On a slime, of course.

"This is a slime, too?" He knocks on the slime. "This is amazing. The entire dungeon is just one grand illusion."

"Yes, it's a slime. I don't know how any dungeon calibrates! They do their own architecture, they could collapse on people, low level tanks couldn't survive that. They could go harder on any of dozens of tactics that they sometimes try briefly and then drop. This one is just calibrating really blatantly. Blatantly if you're me."

"So what do we do about this?"

"You're the party leader."

"Je n'ai aucune idée."

"I wish to ask the dungeon why it is doing this. It explains everything and nothing at all. Everything that is strange about the dungeon compared to others..."

"Well, this one knew the Pyramids and the Moon existed despite existing in the Outback. Maybe they've known how to speak English secretly all along." She clears her throat and addresses the nearest slime. "If you can understand me, please have this slime scoot back one meter."

The slime doesn't scoot.

It does, however, react. Not extremely clearly, but it seems to kind of go still and do the slime body language equivalent of tilting its head and leaning backwards. 

Every slime in the dungeon, actually, seems to go somewhat more still, like they're all straining to hear.

"Did it do anything? Did it do anything?"

"Philippe, patiente."

Pout.

"It didn't scoot but it did something -" She spins around. "They all did something except the one you're sitting on, that one's still a box - but it didn't scoot, like it knew I was talking to it but didn't understand what I said?"

The one she was talking "to" seems to lean towards her when she turns away.

"So... it does not speak English? Does it speak... whatever language the natives from here speak? Français ? Parlez-vous Français ?" he asks his box.

The box slime doesn't react in any way, and it's unclear if the other slimes reacted at all, they're holding reasonably still but they still kind of wobble in place all the time.

"Didn't react to that."

She... waves at the nearest slime. Wave wave.

After a few seconds it bulges out a little long limb and waves back.

"It waved back at me!" she cackles. "I wish they hadn't wrecked my camera - this must be why, if they can't fool electronics -" She waves with her other hand.

"Which is - trop commode -"

It extends another tiny limb to wave back.

"Commode ?"

"Oui. C'est très commode qu'y a qu'elle qui peut voir ces 'gluants'."

"Ah. Euh... Elisabel, I don't suppose there's a way you could, euh... Perhaps convince these slimes to let us see anything different...?"
