Bonnie Bennett

Bonnie comes from the powerful Bennett line of witches, which reaches back to Qetsiyah. In season 1 her grandmother teaches her to embrace her powers.

No character sacrifices as much as Bonnie: she dies, becomes the anchor to the Other Side, spends months in a prison world and loses her magic more than once. Her friendship with Damon, formed in the prison world with Kai Parker, is one of the show’s surprises.

In the finale Bonnie finds a way to break Elena’s curse without dying herself, and then finally sets off for a life of her own.
