Pansy isn't a pureblood, is she? Draco better find himself a pureblood or his dad is liable to transfigure his girlfriend into a mud pie.
Susan Bones and Neville have the same family history. Both their parents were destroyed by Valdemort. I think that will eventually bring them together. Of course, now that I write this, I can't remember which book mentioned Susan Bones parents. Does any one else remember?
