Swamped

"Yeah, I found a ring. Didn't want to keep it on me because I thought it was doing something, so I put it in a safe place for the moment."

The prisoner seems to be very pointedly not looking around the tent. They're looking right at you. They seem to have realized that you know something.

"What do you mean, doing something?"

"Well, like I said, I thought it was magic. It was..."

You pause for a moment to drag out the uncertainty. The prisoner's starting to shake a little, probably from nervousness.

"Heavy," you finally conclude.

They stop shaking, but you can't tell if they're relieved or if they're just calmer now that it's done with. Might as well go all-out with the description, then.

"That is, it felt real heavy for a ring. Even the sand around it felt more like pebbles. I wasn't sure it was safe to be around something like that, so I hid it."

That's odd. The prisoner seems... confused.

"Probably a good idea," Yvonne says. "I'll inform Dominique that you want some tests done."

She turns to the prisoner.

"Have to say, it's real unsettling. If not for the missing tail, she'd look just like Barb. If you are a she."

"It's none of your business who I am," the prisoner says.

"I'd probably agree if you weren't poking around in our camp. But we just had two intruders yesterday whose allies captured someone very dear to me. So perhaps you can understand how I would feel if you were working with the same group."

The prisoner looks Yvonne right in the eyes.

"I'm not working with anyone any more. Been promised one too many golden roses."

A golden rose has silver thorns. The last Guild password you ever learned, and you've rarely heard the saying otherwise. Maybe this prisoner works for the Guild?

You don't think the password trick you tried on Pubert would work here, though. They're too guarded right now. You'll need another way to check that theory.
