"Uh..." Well, at least he'd stopped vomiting for the moment. He turned to the sound of the voice, standing slightly so he wouldn't be in quite as vulnerable of a position when he turned to face the stranger, giving her a full view of his gray, pale skin and dead yellow eyes. He noticed her knife, and decided to proceed with caution. Of course, in this place there were plenty of perfectly innocent reasons to have a knife, so he decided not to act too suspicious.

"Actually, I feel a bit off."

By off, naturally, he meant extremely nauseous as well as something else...a feeling rumbling at the back of his mind. An anger that he didn't usually feel...but he dismissed it as just frustration at his situation and nothing more.
