After a moment's thought, Tracey shrugged. "My sister had a puffskein for a pet once. She didn't even like it all that much, but someone gave it to her and she couldn't get rid of it because it wouldn't be proper. I hated it. It got into my room all the time and left fuzz all over my things. So one day I hexed it, and it died. I told everyone that I just found it like that, but I think Charlotte always knew that I did it."
