They're speaking quietly in Polari but that might not be good enough.

Does he seem to have heard us?

He does not.

"...And the creatures didn't seem to upset them either." (He's going to get a bit euphemistic because he doesn't know the Polari for "byakhee".) "Admittedly it's disturbing to see them all entranced."

"We spend the night -- either at an inn or at the house, both options have their drawbacks -- and then the next day... ritual, I suppose. We'll need a chance to set things up beforehand."

Polari or no, he's not saying 'explosives' out loud.

"I'd recommend an inn. I'd trust the doors there more."

Phew. Still, worth noting that probably some people around will be fluent in Polari. "There might be some kind of... spell over them. I suppose we should have some people who aren't in the room when the moment approaches."

"An inn seems advisable."

Yes, a spell over them seems uncomfortably likely.

"Inaaya, I hope you don't mind me volunteering you -- but you probably will have the best chance of resisting any spell in case some of us do get caught by it."

"Probably true," she agrees.
