It's a good thing she can't speak Common; had she voiced calling him a human, he would have been very offended. As it is, he just goes about finishing eating the cup, which he began to regret doing almost immediately; it's too late now, though. He's committed. He's going to finish eating this cup. Even though the gross wax coating feels like his mouth has gone to hell.

Maybe he'll just spit it out whenever he catches her not looking.

Oh fuck, there's wax all stuck on the inside of his mouth now. But he's gotta stick the landing. He just quietly fetches something that's actually food to eat and... wash the wax down?
