Stefan and Elena are upstairs together. Downstairs, Damon grabs Katherine and slams her against the wall, but then she gets him thinking it's Elena. Stefan comes down and is confused as well. He rushes upstairs and chokes Elena, thinking she's Katherine, but then Katherine reveals herself, basking in her acting skills. Katherine offers to help them with Klaus, although they're all very reluctant to accept it.
Caroline talks to Matt a bit about Tyler and then Matt tells her that the ball is in her court regarding their own relationship. Damon tries to burn Elijah's body but it doesn't work. Damon asks Katherine if she knew he would die if he used the dagger against Elijah but she avoids the question. Damon is tempted to set Katherine on fire but she uses logic against him. She then reveals that she did know he would die, but it was a price she was willing to take to get out of the tomb. Stefan asks Bonnie if she can help get the Martins on their side. Jeremy kisses Bonnie and she says she'll talk to Elena soon about them.
Alaric expresses interest in wanting to tell Jenna the truth about everything but leaves the decision up to Elena. Stefan and Bonnie meet with Jonas and Luka. They tell them that Elijah is dead and they now want to help get their daughter/sister back and help kill Klaus. Damon looks for the location of where a bunch of dead witches were killed and Katherine remembers hearing about it from Emily Bennett. Stefan gets home and tells them that the reason Elijah wanted to find the witch burial ground was so that he could have a witch channel their power and use it to kill Klaus. Jonas and Luka get home and Jonas says they can't trust the others.
Elena, Bonnie, and Caroline are having a girls' night at Elena's. Jenna walks in and joins them, and they decide to go to the Grill. Jonas and Luka perform a spell that allows a projection of Luka--that can also manipulate things--to be inside the Salvatore mansion without being seen. They want to undagger Elijah. Katherine goes downstairs to get some blood and seems to feel a presence. Stefan gets home and Damon shows him a reference in a journal about where the witches were killed. Luka starts pulling the dagger from Elijah and Katherine notices it and starts pushing it back in. Luka lets go and tries to find a stake. He stabs her with a piece of wood but misses her heart. Damon shows up and uses the flamethrower, which burns and kills Luka. Jonas tries to do a spell to reverse it but it doesn't work.
Alaric tries to talk to Jenna but she blows him off, telling him she can handle whatever secret he's keeping. Trying to think of a way to let Matt know how she feels, Caroline gets up on stage and sings after compelling the band to go along with it. The others are nervous at first but realize she actually has a good voice. Matt goes up on stage and kisses her. Jonas does a spell to find Elena and when Stefan shows up, Jonas drops him with the aneurysm move. Damon brings Katherine some blood but also stabs her for not telling him about the deal with the dagger. She reveals that she had to choose between Damon and Stefan and she chose Stefan. At the Grill, Matt and Caroline are making out in the bathroom. Bonnie finally talks to Elena about Jeremy, and Elena gives her blessing. Elena gets a call and walks away, then Bonnie sees Jonas enter the Grill.
When Damon is about to leave the mansion to go help with Jonas, Katherine tells him that she has a plan. Bonnie tries to reason with Jonas but he doesn't listen, causing mayhem in the Grill. Stefan and Elena go to Caroline and ask for help in getting Elena out of there. Jonas drops Bonnie and Matt goes to help her. Elena tells Jonas that she's sorry for what happened to Luka. Caroline suddenly attacks him, but he uses the witch trick on her. Matt sees and attacks Jonas, but Jonas stabs him in the neck with a broken beer bottle. She's forced to heal him with her blood while he's still conscious, so he sees her face change. At the Gilbert residence, Bonnie expresses remorse over what happened and hates the feeling of not being able to help. Stefan and Elena arrive and she heads upstairs to the bathroom.
Jonas appears and grabs her, but then she reveals that she's actually Katherine, and bites him. Bonnie kneels beside him and goes to close his eyes, but he grabs her. Stefan hurriedly snaps his neck. Katherine, while hostile, says she's not a threat to Elena right now since they all want the same thing. Alaric drives Jenna home and admits that there are things about Isobel that he can't tell her, but he does confess that he does love her. Bonnie reveals to Jeremy that when Jonas grabbed her, he returned her powers. Not only that, but he provided her with a way to kill Klaus. Damon figures out that Katherine gave up Emily to the town, knowing she'd be killed. At the same time, Katherine knows Damon is lying about not knowing the location of the witch burial ground. She tries to seduce him but he completely rejects her.
Matt wakes up in Caroline's room and she tells him she's a vampire. Everything with Vicki rushes back to him and Matt accuses Caroline of having something to do with his sister's death. Elena finds Jenna in the kitchen when the doorbell rings. Jenna goes to answer it and Elena follows. On the porch is Isobel. She introduces herself as Elena's mother and Elena calls her by her name as Jenna looks between the two of them, clearly wondering what's going on.
