The Story of Katerina Petrova

Part 2 Katherine Pierce

Katherine stabs John Gilbert.

When Katherine learned of the escape of the Tomb vampires, she gave her descendant and friend, Isobel, a Lapis Lazuli medallion, enabling the young vampire to walk in the sun. Katherine needed the tomb vampires dead because she didn't want Klaus to find out she was still alive, so she had Isobel retrieve Johnathan Gilbert's invention and give it to John Gilbert to use against the vampires in Mystic Falls. This resulted in the deaths of the remaining tomb vampires. In Founder's Day after the chaos has settled, Katherine, having stolen some of Elena Gilbert's clothes, goes to the Gilbert house, where she poses as Elena in the presence of Damon. The two kiss, only to be interrupted by Elena's aunt, Jenna Sommers. Unaware of the presence of vampires or the existence of Katherine, Jenna invites her into the house. Katherine startles John Gilbert in the kitchen, still pretending to be Elena. She notices the magic Gilbert ring he is wearing and, using a butcher's knife, viciously chops his fingers off, then stabs him. Elena arrives and comes to John's aid while Katherine hovers behind her.
Seeing John Gilbert seriously injured, Elena calls for help and is terrified by Katherine's super-speed around the house before leaving. Upon her return, Damon and Stefan are left reeling after she's caused so much damage in so little time. At the mayor's wake at the Lockwood mansion, she engages in a small power play with Bonnie, claiming that it never ends well for Bennett witches. Bonnie attempts her usual attack against vampires, but Katherine, a much older vampire than Bonnie is used to encountering, seems to have a certain amount of resistance to such spells.

Katherine watches Elena!

Katherine claims to Stefan that she returned for him, and the two engage in light banter, Katherine playfully and Stefan suspiciously. Their conversation effectively ends when Stefan tells Katherine he hates her and in retaliation, she skewers him with a metal rod. Later, Damon demand the truth after he and Katherine make out, and she confesses that she never loved him and that "it was always Stefan" that she loved. Later, she visits Caroline Forbes in the hospital and tells her to give the Salvatores a message: "Game on." Then she smothers Caroline with a pillow, killing her with Damon's blood in her system.
