"You do understand that you won't be under our host's protection forever, yes? You'll leave here eventually to go back to your regular life, and some of the guests may feel inclined to go with you. With or without your knowledge." That sounds a little more like a threat than Nam really intends it to. It's meant more as a warning. He may have a certain distaste for humans but that doesn't mean he wants to see one come to harm. At least not without putting in at least a modicum of effort to see it doesn't happen.

Nam steps out around the human and gets two glasses of a lovely looking white wine, then he turns back toward Snake and holds one glass out to him. "Do be careful while you're here, human."
