Hazel Black  - Eclipse
Everything for Hazel and Paul is looking up at first. They're happier than ever and keep each other sane with the return of the Cullen's to Forks. Jacob still isn't happy with their relationship, but he's Hazel's brother. What else would you expect?
Unfortunately for the siblings, it continues to put a strain on their friendship. Not to mention that Bella still seems to have a hold on Jake.
As things begin to get worse in Forks and on the Reservation, Hazel's temper grows worse. It gets to a point that even Paul may not be able to stop her before she takes ruins her relationship with her brother completely.
