It's not like grief about his height of all things is going to get to him, anyway. If anyone knows how inconvenient it is to be as tall as he is in a society where most people are nowhere close to it, it's Billy, after all. He has definitely hit his head. He has folded himself in two like a pretzel just to fit into his small, small bed.

Hence why he can hear the words fuck you and still seem like he's smiling - or at least like he's kind of amused (since it's not like Billy really does smiling) when he speaks again, still lingering very physically close to the other.
