At least five minutes passed before Draco made up his mind. Frustrated that he'd been backed into a corner, he finally agreed to teach her how to track. But, only after she made a vow that she would never tell anyone about the list or the spell. He didn't even make her take an oath on her wand to her surprise. Of course, if she was honest with him and told him that she'd already shared the information about the list with at least three other people, he might not have been so agreeable to teach her.
