Vicki is still being looked for and she shows up in Tyler’s car. She’s afraid. She tells him how hungry she is; how she can’t control it. Then, she attacks him. Stefan and Damon show up just in time. Damon compels Tyler to believe he didn’t see any of them. Is this going to be what slowly brings him to humanity?
Elena wakes up quietly freaked out. She tells Jeremy he should go to school and wait for a call.
Damon and Stefan are playing the angel and devil on Vicki’s shoulders to help her decide who/what to feed from. “We choose our own path. Our values and our actions define who we are,” Stefan says. Damon decides to leave, while he walks away Elena rings the doorbell looking for Stefan. She calls Damon arrogant and glib, he calls her brave and stupid; and she calls him out. “If you wanted me dead, I’d be dead. I’m not.” She asks Stefan about Vicki. He explains that it may take longer for her since she’s a drug addict.
At the Grill, the Mayor and his wife talk about the vampires, how Logan let them get the compass, and how they should be worried that he apparently knows the town history. Damon is sitting there listening.
Stefan explains to Vicki she’ll have to live with the urge to drink human blood and that he isn’t proud of having drank it in the past. Elena makes a face that says she’s trying not to freak out about him drinking human blood. He also tells Vicki caffeine keeps them from being too cold to touch. Stefan leaves Elena to watch Vicki while he gets her more animal blood. She tells her she doesn’t want Jeremy apart of this. Vicki chokes her and threatens her, she strung her brother along for 15 years and then dumped him; that’s all she sees in her. Stefan agrees that Vicki shouldn’t see Jeremy.
Vicki asks Damon why he did it. He says he was bored. “One of the pitfalls of eternal life.” He and Stefan show her the perks of being a vampire. Speed. When she tries, she shows up home, but finds she can’t go in without an invitation. Matt is there and says the right words to get her inside. He gets mad about her “drug trip.” She starts complaining about her headache. Then, Stefan shows up and asks to come in, she says don’t let him in, so Matt tells him to leave.
Elena tries again to encourage Jeremy to let Vicki go so she can heal. He explains Vicki has been for him what Stefan has been for her—a bright spot in the darkness. She texts him, saying she’ll be at the high school party.
At the Grill, Damon tries to compel the Mayor’s wife, but she’s wearing vervain in her bracelet. They flirt with each other. She tells him about the counsel and asks for more vervain.
At the Halloween party, Matt tells Elena Vicki is there dressed as a vampire. She’s trying to fight her urge, but she’s starting to lose it. Stefan gets there and drags her to a classroom. Vicki tries to get Matt to believe Stefan won’t leave her alone. Elena tries to assure Matt everything is ok. Matt tries to fight, but Stefan urges him to believe he’s trying to help her.
Damon tries to take the jewel form Bonnie who is wearing it a part of her witch costumer per Caroline’s request. She burns him.
Vicki asks Jeremy to leave with her. She bites his lip while they’re making out and she tastes his blood. He sees her vamp up and watches her use her super strength on Elena and Stefan. Stefan stakes Vicki after she feeds from Elena. She cries over Vicki’s body after telling Stefan to take Jeremy away. Stefan calls Damon for help with the corpse. When he shows up, Elena starts hitting at him, accusing him of caring when he says he doesn’t. He warns her that she needs to leave. “Your wounds are bleeding and you need to leave.” She does leave, blames the blood on an “idiot with fake blood” when Matt asks about it, and lies about not knowing where Vicki is. After walking away, she starts crying in the car. She doesn’t want to lie. She doesn’t want to be a part of any of this.
At home, Stefan is waiting for Elena and Jeremy is in his room crying. She goes to comfort him. Asking if she understands what happened. He knows what he saw, but he doesn’t understand. Stefan sits outside listening to the emotional battle. “Why does everyone have to die on me,” Jeremy asks. Elena goes to check on Stefan and asks him to make Jeremy forget. Stefan explains he can’t do it right because of how he lives. Damon shows up and says he can do it. He just asks what she wants him to believe. “She left town. She’s not coming back. He shouldn’t look for her or worry about him. It’s going to hurt, but he’ll move on.” When Damon goes inside, she tells Stefan she wants to forget everything, but she can’t. She can’t forget how she feels about him.
