Caroline is at the Salvatore mansion telling Damon and Stefan about her encounter with Katherine at The Grill. She had gone there to “stalk” Matt, but he treated her like a customer so she pretended she had to go to the bathroom. In the bathroom she saw “Elena” but quickly realized it was Katherine and asked what she wanted. Kat said to give the Salvatores a message: give Kat the moonstone at the Masquerade Ball tonight or else she would kill more innocents. Damon and Stef are pissed. Damon says that he will kill Katherine at the Ball tonight but Stefan says that Damon will do no such thing because he’s going to kill her.
Aunt Jenna is brought home to the Gilbert house and recovering from her “walking into a knife” attack. Jeremy asks Elena about Katherine. Elena tells him that Kat won because she doesn’t want any more people that she loves get hurt. She thinks that since she broke it off with Stefan that Kat will stop with her evil ways. Jeremy takes off.
At the Salvatore’s Damon, Stef, Alaric, Jeremy, Caroline and Bonnie gather to look at vampire stake equipment for the evening’s festivities. They need Bonnie’s witchy powers to help them with their plan. Even though Bonnie swore she was done with them she seems to always get involved and this time she seems happy to help. Alaric promises Stefan that he’ll look after Elena tonight to make sure she doesn’t go to the Ball.
At Katherine’s B&B she’s done some shopping and the owner Mrs. Flowers helps bring her bags up to her room. Enter a mysterious black woman. It’s a witch named Lucy who is helping Kat tonight with her plan because Lucy owes Kat a favor.
Before the Lockwood party Tyler again questions his mom about hearing from Mason. They have a little bonding session where Ty apologizes for being a dick, er I mean a jerk. Carol tells Ty that they probably won’t hear from Mason because that’s just how he is.
At the Ball Kat and Lucy show up. Katherine talks to Matt and confirms that he’ll do her bidding. Matt goes to find Tyler who’s with Amy and Sarah – the two girls from previous episodes. Matt starts to drink shots and Ty says it’s not like him but goes along.
Jeremy and Bonnie go upstairs to find a room that will work for their plan. Bonnie is going to seal it up like the tomb where vampires can’t escape. They walk downstairs and Bonnie feels a weird vibe. She follows it and finds Lucy. She says “Do I know you?” And Lucy replies “No” and walks away.
Stefan finds Katherine outside and she asks to dance with him. Stefan declines but does it when she threatens to kill more people. He tells her that they’ll go get the moonstone together but she knows it’s a trap so she tells him to go fetch it and bring it back. He says no. So then Amy shows up and compliments “Elena” on her dress. Kat thanks her and says she likes her necklace, goes behind her, paralyzes her and then kills her. Stef is shocked.
Stefan runs upstairs and tells Damon he doesn’t want to do the plan anymore. But Damon tells him they have to.
Lucy talks to Kat about another witch being at the Ball, that it wasn’t part of the plan and a game changer. Jeremy interrupts to tell Kat that Stef and Damon have the moonstone and will give it to her by the lake.
Elena manages to sneak out of the house and is hiding in the bushes. She grabs Jer and asks what’s happening.
Kat finds Caroline and chokes her. Kat asks her what the Salvatores are up to. Care at first says nothing, but finally she admits that they want to kill her and are upstairs. Kat drags her upstairs to the room. Kat sees Stef and walks into the room and Caroline hangs back. Care exclaims that she did it. Kat can’t get out of the bewitched room and Caroline waves bye at her triumphantly. Stef attacks her and Damon shoots her in the back with a stake. But down in the bushes with Jer and Bonnie, Elena is feeling the exact same pain as Kat. Oh NO. Lucy bewitched the two so they would feel each other’s pain. Jeremy runs upstairs to tell the Salvatores to stop. Damon is about to stake her when Jer gets there and they stop. Then Kat decides to torture herself so Elena hurts more by dragging the stake across her hand. Down in the bushes Elena is in agony. Bonnie tries to help but the spell is too powerful and she can’t break it. She can only take away some of Elena’s pain. Jeremy tells Elena to wear the magic ring.
Upstairs, the Salvatores are asking Kat why she wants the moonstone and a werewolf. Stefan realizes that she gave the moonstone to George Lockwood to fake her death. Damon deduces something about the moonstone not belonging to her and that she needs to get it back to give it to someone.
Bonnie runs off to find the other witch. She catches up to her and doesn’t back down. Lucy senses the moonstone on her and grabs her arms. Lucy then tells her that the vibe that Bonnie’s feeling is trust.
Lucy shows up in the sealed room with the moonstone. She claims her debt is done and the room is no longer sealed. Lucy gives a smirking Katherine the moonstone and leaves. But when Kat touches the moonstone she shrieks in agony and writhes around, finally dropping to the ground.
Downstairs in the study, Matt, Tyler and Sarah are hanging out. Matt provokes Ty by pouring vodka on the floor, on the picture of his dad and finally smashing the picture. The two are fighting when Caroline (yay) shows up. She realizes Matt is compelled and elbows him to unconsciousness. But then Sarah starts muttering something about “if he fails then I have to continue.” She picks up a letter opener and stabs Ty in the chest. Ty pushes her away, she cracks her skull on the desk when she falls and is dead. Caroline feels her pulse but Ty starts scratching at his chest and finally his eyes turn wolfy.
Lucy is leaving the party when Bonnie runs up to her. She has so many questions. Lucy reveals that they are related and that she’s done with vampires. Bonnie says she wants to be done with them too but Lucy tells her that she’s in a good place. Jeremy catches up to Bonnie and tells her that he’s grown up. The two leave together. New romance alert.
Caroline tells Mrs. Lockwood that Sarah had an accident and that’s why she’s dead. Tyler questions why Caroline is getting involved. Caroline reveals that Ty’s wound is gone, he feels that it is and wonders how she knew that.
Stefan meets up with Elena and asks how she is. He leans in to hold her but she backs away. She needs space even though Katherine is gone.
Katherine wakes up in the tomb with the moonstone in her hand and tries to get out, but she’s sealed in! Damon is there and tells her she’s where she should’ve been 145 years ago. Kat says they should’ve killed her but Damon says that would be too kind. Kat tells him that she has to get out and that Elena is in danger because they’re doppelgangers. Damon says that he’ll take care of Elena and closes the door.
Elena is talking to Jeremy on the phone and says she can get home by herself. Then a masked person grabs her and takes her away. Ay ya yai.
