"Blaise, look at me, please." When the Slytherin looked up, his master promised, "You are mine now. I protect what's mine, no matter if they are "of use" or not. You want to come, I'll find a way to make that happen. You want to go home, I'll let you. I'm not a tyrant who will dictate your every move. You know what I want, and you agreed to my agenda. If we can't work on that, we're still friends. Stop thinking in Slytherin terms. I'm not a snake."
