Okay now Nida's genuinely invested in the story. Mostly because he's half horrified of the idea of bringing poison into the bedroom. Weapons, maybe. Restraint, possibly. But poisons? Pretty dangerous. Of course there is another question about why someone would need that sort of poison, but Nida can easily draw that conclusion.

"A full chest of the stuff?" Nida asked, leaning in himself. Yes, he might be a touch invested now. "That's a bit excessive if it's that potent. Well... did you use it?"

Hyne help him, he has to know if the lady lived.

Granted now he really knows what Altair meant when he advised not trusting people, but he could have drawn that conclusion himself.
