Words are going over Jules' head, there, but he gets the gist of it. He's always been fairly sensitive, after all.

"I can be quiet." He rather often is, actually. It's hard for him to interact with his peers since he either can't hold a conversation on the same level, or they don't have the patience to deal with him. Sometimes both, and more.

And no, he has absolutely no idea what is going on. Not in the least. And it's quite possible he wouldn't understand it even if explained to him.
