L is used to the feeling that someone is watching him. Through the course of his life, servants have often been silently omnipresent, and there's also the matter of being sure that he has the attention of the research assistants. Still, sometimes he feels a prickle at the back of his neck, and he's always in the habit of scanning the room to catch anything he's missed.

"And who do you belong to?"

It's not hard to guess. Violet eyes are extremely rare.
