Theo didn't have the energy for this, he wanted the wand, he wanted to feel that she was actually dead. It meant more than any head he could barely stand to look at would. Yet he didn't feel like explaining himself to Jander. It was none of his business.
He had a feeling that saying that would cost him though, so he kept his mouth shut. 'Because I'd like the satisfaction of knowing that I have the her wand,' he said calmly instead. He still wasn't sure what he would do when he got it. Snap it in two? See if he could use it? Probably not he would not be the owner - but at least he'd have a trophy that he could stand to see.
