Katherine promises John Gilbert that she will help protect her descendant Elena Gilbert, even though the younger doppelgÃ¤nger is her competition for the Salvatores' affections. She is initially portrayed as the main antagonist, but upon the arrival of Elijah, one of the Original vampires, Katherine is clearly terrified by the prospect of finally being caught by Klaus. Once she escapes at the end of the second season, she flees Mystic Falls almost immediately. Later returning to Mystic Falls in season 4; killing Elena's brother Jeremy Gilbert, to acquire a cure for vampirism while trying to negotiate a deal with Klaus for her freedom. This however; backfires on her, when Elena shoves the cure into her mouth during a fight, turning her human. Over the next season Katherine finds her long lost daughter, Nadia Petrova. Katherine's body is over 500 years and can't hold up to her being human. So, together Katherine and Nadia decide to plant Katherine's soul into Elena's body, but once Elena's friends discover this, she is stabbed to be extracted from Elena's body and she dies beside her daughter who dies just moments earlier from a hybrid bite.
