"That was my basic reaction as well. Anyway, from what she said before she passed out, this is Trixie Black, just graduated student of Hogwarts. As near as I can figure; when I killed Rodolphus, a spell that he had on her was broken, and she reverted to the age and condition she was when the spell was first cast. Look, the dark mark has completely disappeared, and she looks to be about 17 years old. To make life even more interesting, she seems to think I'm James Potter, and she asked me if I was going to play with her and Sirius again. I think that she and I need to have a bit of a discussion when I get her back to Hogwarts."
