While she’s in math class, someone named Emily draws Bonnie from class and asks for help. Then she wakes up in the same class and it’s nightmare only to wake up in the woods again after seeing Emily in class. Emily says they’re family. Bonnie rushes into class slightly unhinged explaining the dream. At lunch, Bonnie explains everything to Elena and asks if she believes in ghosts, “Two weeks ago I would have said no, but now…” Bonnie thinks Elena, her great, great grandmother who originally owned the talisman is haunting her.
Caroline walks past Matt who acts like nothing happened between them. She goes off on him after the second “hey.” He explains he left because he heard her mom and didn’t want to get her in trouble.
In history class, the students get a new teacher. I have a feeling he’s going to play an important role in what’s to come. He tells Jeremy about a “jackass file” the old teacher had, mostly it was him. He offers an extra credit project to catch him up. Jeremy notices a ring he’s wearing! He says it’s a family ring. Ha! It’s gotta be like the Salvatore rings. Jenna and Jeremy have dinner at the Grill and see the new teacher. She’s interested, but not. At the Grill, the teacher and Jenna flirt. She shares her story about Logan. He shares his story about a young marriage and early death. Yup! Definitely a vampire! He doesn’t come into the house without an invitation. When she does she won’t invite him, he leaves.
Damon wakes Stefan up and offers coffee. They banter as usual. Stefan shows up at school and explains he didn’t kill his brother because of her and that he won’t be coming to school anymore, putting distance between them. She’s mad, he’s glad. It’s easier if she hates him.
Damon comes to the school and threatens Bonnie after explaining he knows she’s a witch, he knows about the dreams/haunting of Emily, and that apparently he and Emily had some kind of a deal. Maybe she gave him the crystal? Time will tell. She tells Elena and Elena tells her to stay away from him and to stay with her tonight. She gets out of the car and throws her medallion out into a field. Caroline goes to Elena’s house for a girl’s night too. Bonnie tells Caroline she tossed the necklace and Elena confirms it, but Caroline finds it in Bonnie’s bag after being given permission to look through it. Bonnie tells her she’s a witch, but Caroline doesn’t listen at first. She says she doesn’t believe in that stuff, but if Bonnie does then she will too. Then, they summon Emily who freaks them out and takes the necklace. Emily walks through the house and leaves the medallion on the ground to trap Bonnie. Emily messes with the lights, seems to be torturing Bonnie in the bathroom she’s trapped in. Then, all of a sudden, she says she’s fine. I’m pretty sure Emily must have possessed her. Oh, and she did! It’s her reflection in the mirror, not Bonnie’s!
Elena tells Stefan about Damon’s threat. The medallion belonged to Katherine. Emily, her handmaid and witch, gave it to her. Stefan finds Damon at the Grill. They play darts and Damon asks what Stefan’s game is. Stefan laughs because he’s been asking him the same thing for months. They go to the football field and play football together. He knows he’s trying to get something from him. Stefan talks about how their love for Katherine wasn’t real. They were compelled to love her. Damon always thought he was the last to see her, but Stefan tells him it was really him. Damon confesses he wants the crystal because he’s going to try to bring Katherine back. Damon begged Emily to save Katherine. She did. She trapped her in a grave or something under the church. The downfall was that it only worked with the comet, so to free her from the grave, she’d have to wait until the next comet. 150 years later. That’s why Emily is haunting Bonnie. She doesn’t want to keep her end of the bargain. Damon preserves Emily’s lineage for her saving Katherine. When she doesn’t answer, Elena knows it’s Bonnie. Elena calls Stefan and Damon listens to the call. They know she’s going to the church. Emily uses her powers to keep Damon from following her. He gets almost staked by a tree. Stefan lets him down. Emily explains in order to save Katherine, she had to save all the vampires in the church. That’s why she won’t keep her end of the bargain. She can’t bring all those vampires back. Damon attacks Bonnie’s body. Stefan saves her by feeding her his blood, because she’s only barely alive. Damon tells Stefan Katherine never compelled him. He knew every step of the way. For him it was real. And now he’s going to leave. Bonnie keeps asking questions. Elena tells her she’ll explain everything. Stefan doesn’t argue. She tells him she can do this. She doesn’t have to stay away from him, but he can’t. He has to leave. It was a mistake for him to come home. She begs him not to walk away. He does. through tears, Elena tells Bonnie everything, even that he’s leaving.
After Caroline goes home, Matt comes by her room. He confesses it creeped him out that they cuddled, because he’s never liked her, but it felt nice. He wanted her to know he stayed because he felt bad for her, because he knows how it feels to feel alone. He spends the night with her again.
Oh, snap! Logan isn’t dead! He’s a vampire now! He shows up at the Gilbert house and asks, “Aren’t you gonna invite me in?”
