Whatever happened to...?

Whatever happened to Kristy Watson? She was Mary Jane's teenage cousin. She went to stay with the Parkers when her parents left for Europe. There, she fell in love with Peter,and developed bulimia (which she may have had before). Eventually she overcame her bulimia with hospital care and meetings and the Parkers were able to keep her around for "a few months" while her parents stayed in Paris, and she went to work as a live-in baby sitter for little Normie Osborn. And to the best of my knowledge, this was the last anyone ever saw of her.



Now, I understand that her main purpose was the bulimia storyline. She was introduced to act as a type of public service announcement, bulimia=bad. And once her story was over they decided to send her off into the sunset with a "happy" ending. But she was still a character that was around for a little while, and then just disappeared.

So, what exactly did happen to her? Did her parents finally come home and take her back, even though they didn't even care that she nearly died? Did Norman kill her because he was not going to let members of Spider-Man's family babysit his grandson? (Maybe Norman made it look like she started purging again.) Or is she still there, watching little Normie, between panels when his mother isn't watching him? What happened to her?
