Connor continues to talk to her and Elena gets scared and yells out to Jeremy. She tells Connors that she killed him and he is a ghost whose haunting her. He asks her if she is sure because ghosts can't do this- he grabs her around the neck strangling her. She gets out of his hold, picks a kitchen knife and stabs him in the neck only to realize that she has stabbed Jeremy instead of Connor. Jeremy falls to the ground but he has his ring on so he'll be fine. Elena is shown pacing the room talking to Damon while Jeremy lies dead on the sofa. Damon insists she should have called Stefan but Elena says she doesn't trust Stefan, he has been lying to her. Stefan enters the house & Damon says he called Stefan. When Stefan tries to talk to Elena she excuses herself saying she needs to wash the blood off her hands.
Stefan goes to her room & tries to talk to her but she refuses to listen saying he has been lying to her and working with Klaus. At the Lockwood house, Hayley and the hybrids have been drinking all night.

There is a knock on the door & it's Caroline. She returns all of Tyler's things and breaks off with him. Klaus witnesses all this and asks the rest to leave them alone for a while. Just as Klaus leaves, Tyler, Hayley & Caroline smile - it was a fake breakup for Klaus's sake. Tyler & Caroline kiss and Hayley is seen giving them a look.
Elena is showering when she sees blood in the bath tub only to realize that she is hallucinating. Meanwhile Damon & Stefan are talking in the kitchen and Stefan gets a call from Klaus. Klaus taunts him about ruining his plans for a hybrid filled future and asks him how Elena was doing - had her hallucinations have started yet. Stefan asks him how he knows that. Klaus says he killed the original five hunters so he knows and asks Stefan where he is. Stefan says he is at Elena's place. Klaus is also there. Stefan comes out to talk to him and Klaus suggests he hand over Elena to him else she'll kill herself before the end of the day - the witches had created the hunters to kill vampires and if a hunter dies he will still kill the vampire that killed him. Elena is hallucinating again and runs from her room to the kitchen where she sees Damon but he turns in to Connor. She runs out of the house and Klaus takes this opportunity to carry her away. Damon & Stefan are left standing on the porch.

She, however, says that they could ask Prof. Shane as he knows everything about everything! She & Damon head towards the school while Stefan goes to look for Elena. Klaus puts Elena in a windowless room. He says it is for her protection else she'll take off her daylight ring & burn herself to death. Elena says she would notdo that however Klaus tells her she'll want to kill herself as he had once. The only problem was he was immortal hence had to bear the torture for nearly 52years. She asks him how he stopped it and he responds that he didn't. He tells her that one day it stopped on it's own and then leaves her alone in the room.

Meanwhile Stefan & Tyler talk to Chris to help them and he reluctantly agrees on the condition that he leaves the place once the job is done. Caroline goes to Mystic Grill to distract Klaus so Stefan can get Elena out. As Stefan opens the door to the room, Elena who is already hallucinating, attacks him and runs away. He then calls Damon to tell him that he has lost Elena again and that Damon should go find her & talk to her as she listens to him. Stefan texts Caroline to tell her that he has lost Elena but the hunter's curse can be broken if Jeremy kills a vampire.
