"The setting was the tent rather than the Rope Trick, paperwork replaced with sawdust and the fabric strips with snakes, and a hall of sorts instead of the expected exit. Therein a woman I did not recognize was on the far side of a powdered silver circle, though I did not look at it closely enough to make sure it was consistent with any Magic Circle, and she attempted to enchant me into being angry enough to approach more closely when merely, uh, wanting it at me, was not efficacious. This did not feel subjectively very challenging to throw off and when she attempted to pull harder I woke up. - has it been two hours?"

 "It's only been a few minutes."

"I didn't see an enchantment on you, for whatever that's worth. Or illusion, or transmutation, but I'm not sure if I would."

"Thank you for checking. Is there anything else obviously worth checking that I'm missing?"

"We could check the tent again."

 "We did, multiple times."

"It can't hurt."

"It wouldn't do to become so tired of checking the tent that we become predictably unlikely to. But I admit I do not expect anything to turn up." Tent check.

...Detect Magic guy reports that there's a tiny insect with the dim aura of a lingering divination spell hanging out in the non-Rope-Trick part of the tent.

 "Why is there a bug here. There's not supposed to be a bug here. We checked for that."

Can they kill the bug.

They can kill the bug. It's not any more difficult to kill than a normal bug.

"Do you have a theory about how it got in?"

"There were some extra people in there putting up the fabric, one of them might have brought it in. We can put together a list."

"Thank you." Sigh. "Anything else to check?" Before he goes straight back to sleep, but it's better to maintain slight ambiguity about exactly when that is for anyone without need to know.
