Elena wakes up with Stefan. They make out. She gets up to get ready for their next day of pretending to fight. She pricks her finger and he drinks to make himself stronger. She says I love you and they kiss.
Jenna invites Stefan over for dinner. He tells her they’re taking a pause. She says that’s not what it sounded like this morning. She’s a light sleeper. “You know what? I heard nothing.” And she walks away smirking.
Damon startles Elena. He’s there looking for his baby brother and she needs to tell hers to stop following him.
Elena goes to the estate and talks to Stefan. They were stupid thinking they wouldn’t get caught because they pretended to fight. She breaks up with Stefan. They know they have to be over. They love each other and they kiss one last time while crying and Elena leaves. She holds her stomach while she walks away. Damon tries to apologize to Elena for riling her up and not thinking. “It doesn’t matter, Damon. Katherine won. She won.” She leaves and he chokes back tears.
Katherine and Werewolves
Katherine and Mason make fool around. She asks him where the stone is and he won’t tell her. He doesn’t trust anyone. She says she loves him, he’s surprised but says it back.
Mason is surprised to see Stefan. Bonnie and Mason bump into each other and Bonnie sees him kissing Elena. Stefan realizes it’s Katherine.
Stefan tells Damon about Katherine and Mason and he can’t believe it. He’s a werewolf and a surfer. She thinks he’s using her for the stone.
Jeremy asks Tyler about the stone and spins a story about being curious about the folklore. Tyler tells him he gave it Mason. Elena texts Stefan to see if everything is okay. He tells he’s with Bonnie and Damon. They ask her to touch Mason again to see if she can see where the stone is. When she says it’s not her choice what she sees, Damon asks her to make his brain go “pop.” She tells him it’s aneurism. Since his brain heals quickly, she can do it over and over again. She doesn’t want to do it. Damon reminds her Mason and Katherine are the bad guys and they’re putting Elena in danger.
Bonnie pretends to need help with something and Mason helps her. She does the brain thing and Damon kicks him in the face to knock him out. They take his truck and drive away.
Bonnie and Damon lock Mason to a chair and Bonnie touches Mason’s head to find what she can about the stone. It’s in a well. She quickly leaves.
Stefan comes back inside and Tyler asks about Mason. Stefan tells him he left and wasn’t sure when he’d be back. Stefan gets a text from Bonnie about the well. Elena tries to go with him. He says no. Matt sees. Elena follows Stefan anyway.
Damon sticks a burning sword through Mason’s chest. He heals quickly but still feels pain. He spits out when Damon asks about Katherine. He runs him through again.
Stefan gets to the well and looks through its covering. Elena catches up to him. He tells her she shouldn’t be there. She knows, but she is. He tells her Bonnie thinks the moon stone is down there. He rips the cover off and jumps down into the well. It’s full of something, probably vervain, and it quickly burns him. Elena tries to throw the chains down the well, but it’s too heavy. Caroline arrives right on time and throws the chains down to Stefan.
Damon confirms supernaturals can’t be compelled. Jeremy comes in. Damon tells him he’s not supposed to be in there, but he has news. Some kind of plant that is a werewolf’s version of vervain. Damon uses it on Mason and Jeremy doesn’t like it. When Mason still won’t answer straight, he feeds it to him.
Bonnie shows up at the well wondering why Caroline took off in a blur. She heard Elena screaming. Caroline lowers Elena down the well to help Stefan. Elena wraps the chains to Stefan. Bonnie and Caroline pull him out. Elena waits to be pulled up until she finds the stone. When she thinks she finds it, a bunch of snakes start coming after her. As soon as she’s up, she runs to Stefan who is very badly burned. She cuts her hand and feeds him. The other girls turn away.
Jeremy basically tells Damon to stop torturing Mason. Before Damon goes to burn his eyes, Mason tells Damon it’s in the well, he’s getting it for Katherine, and she’s going to use it to lift the curse. Damon asks him why a vampire would help a werewolf lift a curse that keeps them from turning whenever they want. He says so he won’t have to turn anymore, because she loves him. Damon looks at him pitifully and laughs. “Katherine doesn’t love you, she’s using you, you moron.” Mason says he’s done talking. Damon agrees and tells Jeremy to go for a walk. Jeremy says no. Mason’s had enough. Mason asks Jeremy to just help Tyler from turning. When Jeremy still won’t leave, Damon chokes him saying it’s either kill or be killed. The werewolf would kill him the first chance he got. “So you suck it up or leave.” He lets him. “HE wants me to kill him anyway. It really is a curse isn’t it?” He says Mason reminds him of himself. Mason says he loves her. Damon knows. He’s been there, but Katherine will just rip his heart out. He does it for her.
Damon sends a text to Mrs. Lockwood with Mason’s phone. Then, he calls Katherine and taunts her. She says for once he’s surprised her. He tells her Mason hid the stone at the bottom of a well full of vervain. He tells her he loved her. She reminds him that she has a plan for every letter of the alphabet. She sends her love to Stefan and hangs up. He knows he’s been foolish.
Elena goes down stairs and subtly tells Alaric everything went as planned. Katherine calls. She knows about Elena and Stefan not really fighting. Katherine was able to convince Jenna to stop wearing her vervain perfume and drinking her vervain tea. When the vervain was out of her system, Katherine made Jenna her spy. She makes Jenna stab herself with a knife. She puts it in her gut. Alaric and Elena both freak out, Elena dropping the phone.
Tyler gets home and asks about Mason. His mom tells him Mason went back to Florida. He doesn’t seem surprised.
Katherine compels Matt to go after Tyler until he kills him so she can have a new werewolf. Why does she need a werewolf?
Jeremy goes to talk to Damon about Tyler, Mason, and the moonstone. Damon asks Jeremy told Elena. He hasn’t.
Alaric comes by the estate and asks if Elena knows Jeremy is there. Alaric tells Jeremy about the Aztec curse. Then, he keeps telling Damon and Jeremy more. Apparently, the moonstone is the seal to the curse. I guess Mason and Katherine think they can break the curse.
Bonnie comes to the Lockwood house to help set up for the masquerade party. She hasn’t been around much and she thinks Caroline has picked sides with Caroline. Elena tells her it’s not about picking sides. Elena asks Bonnie to go somewhere quiet with her to talk.
Elena tells Bonnie everything about and relating to Katherine. Elena hasn’t told Bonnie much because she doesn’t like vampires, so she hasn’t been sure how much she wants to know or hear. She tells her Caroline needs her. Bonnie says she’s not ready yet.
Before Bonnie can leave, Caroline stops her. She asks Caroline about her mom and Caroline asks about the stone. They talk about a well they used to play in as kids and Bonnie thinks that’s where it is. Caroline offers to help Bonnie find it. At first she declines, but then she agrees.
Caroline goes to check on her mom. Her mom won’t talk to her. Caroline asks if she’s really going to pretend she doesn’t against. “As usual, you don’t care. Just like before I was a vampire. It’s not like I died or anything.” She asks if she’s really dead. “Yes and no.” She wonders how it’s possible.
Matt talks to Tyler about Caroline. Tyler talks about Caroline’s insecurities being from a good place.
Caroline tells her mom everything including that she’s better than Stefan who’s basically a bloodaholic. While they’re talking, she tells her Damon’s home.
Matt asks Elena where Caroline is. He can’t believe she’s not there. He asks if she’s seeing someone. Elena assures her she isn’t.
Caroline tells her mom about the day. Her mom is impressed with the strong and confident person Caroline has become. Then, she tells Caroline she doesn’t have to take away her memories. She’ll never tell her secret. If she’s worried about the others, she can tell them she compelled her. She tells her mom she’s grateful for the day and that she trusts her, but she’ll never trust the vampires. Caroline compels her mom into believing she’s been sick, not remembering about the vampires, and believing her daughter still hates her.
Alaric is at the house with Jenna. She’s in the kitchen and he goes to the dining room to get salt. He sees Elena sneak in, mouths if everything is okay, she nods her head, shh’s him and tells him she’s going upstairs.
At the hospital, Elena tells Jeremy the doctor said Jenna got lucky and missed all her major insides. Jeremy tells Elena Katherine is going to pay. He doesn’t know how, but she is. He holds her comfortingly. For once, Elena doesn’t warn him to be careful.
