He takes both and downs them both readily, smacking his lips a few times after they're drained. He figures Schön is on the level when business is at hand. And besides, if he poisoned him, he wouldn't be able to call in a favour to the great and powerful Ixis Naugus! A horrid loss for anyone, surely.

He sits and frowns for a moment, wondering if the draughts are even doing anything. Or if he took this medicine for no reason and now he's going to be stuck with a favour when he never had a pierced spleen to begin with. (If he even has a spleen at all. It STILL sounds made up.)

But then he coughs. And coughs even harder still, lurching forward with the effort and force of each one, clutching his chest soon with his one good hand. And soon the fruit of that apparent labour is him drooling, you guessed it, even more blood. Naugus looks up at Schön with ears flat in suspicion. Is that evidence of poison or just ("just") a punctured lung having been part of his damage? (Spoiler: it's the second one.)
