Isobel comes back to Mystic Falls and shows up at the Gilbert’s front door. Jenna, who thought Isobel was dead, is surprised and feels betrayed when she discovers Elena and Alaric both knew she was alive. But why has Isobel returned? Isobel immediately lets Katherine in on her plan. Isobel claims Klaus has agreed to keep Katherine alive if they can bring him the moonstone and the doppelganger, Elena.
First, she weakens Alaric so one of her accomplices can take him away. Then she stages a distraction so Katherine can kidnap Elena and pretend to take her place. Meanwhile, Isobel takes Elena and drives her to the cemetery. But, it turns out that Isobel was not on Katherine’s side at all, and was only trying to help Klaus capture her. Once they get to the ceremony she lets Elena go free. When Katherine wakes up she is in a room with one of Klaus’ men and Alaric. Klaus has taken control of Alaric’s body and is now possessing him.
