Calling it now. After finally starting to become one of the good guys, Katerina Petrova dies. It's the perfect dramatic ending. And they said a female character would die. Can't be Rebekah, she's in the The Originals spin-off. Can't be Elena, she's the heroine. Can't be Catherine, her and Klaus are the fans' favorite couple. It's probably gonna be Katherine. Anyway, Elijah has to leave... he will be in The Originals. He won't have any reason to hang around Mystic Falls if Katherine is dead.
