Isabelle and Alaric sit together at the Grill. He asks where she’s been. She tells him she doesn’t have any answers that will satisfy him. She asks him to deliver a message to Elena so they can meet. He refuses. Isabelle follows him outside and threatens him. If he doesn’t do what she asks, then she’s going to kill everyone in town one by one and start with his students. Alaric gathers Damon, Elena, and Stefan in his classroom. He tells Elena and Stefan first and recaps Damon when he’s late. Damon is shocked and immediately looks at Elena to see how she’s doing.
Elena calls Damon to check on Stefan. They flirt like normal. Stefan’s standing at the door when Damon gets off the phone with Elena. Damon gives him his phone and tells him she called. Damon assures Elena she doesn’t have to go meet her mother if she doesn’t want to. Then they tell Damon about the killing spree threat. Stefan goes with her to Grill while she meets Isabelle. He sits away at a distance. Isabelle walks in like there’s no problem. She is shocked by how much Elena looks like Katherine. Katherine found her after she was turned. Elena starts asking Isabelle questions immediately. When she says not caring about human life is part of who she is, Elena contradicts her. Isabelle asks why she chose Stefan. Why not Damon? Or does she enjoy both? She is shocked by the question and doesn’t answer. Stefan looks down at his feet. Damon and Alaric are waiting outside talking about Isabelle. Alaric doesn’t understand. Stefan still has his humanity. Even Damon is a dick who kills people has something in him, but Isabelle is different. Damon tells him you can turn it off. Every instinct in a vampire is not to feel. Stefan doesn’t turn any of it off. Isabelle turns it all off. Damon only turns some of it off. Isabelle tells Elena to get the invention for her or it’ll be her fault people die.
Caroline and Bonnie discuss their float for the founder’s parade. Caroline doesn’t understand why everyone is fighting right now. Building the floats are supposed to be about friendship, but Tyler and Matt hate each other and Bonnie and Elena aren’t talking. Tyler tries to make amends with Matt or at least check on how he’s doing, but Matt won’t have it.
Bonnie walks in right as Isabelle leaves and sees Elena crying. She has an internal debate about whether to comfort her or not. When Stefan walks up, Bonnie leaves. Bonnie comes to Elena’s house before school and apologizes. She doesn’t want that to be their friendship. Elena tells Bonnie everything. Bonnie tells her Jonathan Gilbert never succeeded in inventing anything. Emily spelled all of his inventions including the mystery invention. Emily pledged her loyalty to Katherine, but she couldn’t stand by and watch innocent people die. Bonnie reads the spell book and tells her the mystery device is a weapon against vampires.
When John gets home, Isabel is watching two humans she turned into her puppets. She and John are in to together to get the invention. Damon is at Isabelle’s house and plays strip poker with her female puppet. Isabelle and Damon flirt and fool around. She says they have the same goal, working for Katherine. He attacks her. “Now that I have your attention, listen up. You do not come into my town and threaten the people I care about. Going after Elena—bad move. You leave her alone or I will rip you to bits because I do believe in killing the messenger. You know why? Because it sends a message. If Katherine wants something from me. You tell that little B- to come get it herself.”
Jeremy tries calling Anna again, but she’s not answering. Jenna likes her and her fire. John walks in and asks Jeremy about how well he knows Anna. He offers all his help, because his dad would want him to. While Elena is looking for Stefan, Jeremy asks Elena for advice or info on Anna and he tells her he knows what she is and that Elena knows. Elena really doesn’t know where she is. Elena turns around and Isabelle is there. She starts ticking off the people Elena cares about. Elena tries to tell Isabelle to leave, but Isabelle has friends around everyone Elena cares about. One of them hurts Matt and another takes Jeremy. Isabelle doesn’t believe how much Damon cares about Elena. She calls John over and John tries to get to the old friend he grew up with inside her, but she’s gone. She takes his special ring and has her puppets beat him. John tells Jeremy the plan is to get rid of all the old vampires and that his dad is the one taught him about the family history. Jeremy doesn’t believe all vampires are bad. John and apparently their father didn’t agree. He believed all vampires were bad, or so John says.
Elena tries to convince Damon to give her the device. He tries to argue, but he gives in. Bonnie can take the spell away to keep the device from working. That’s the plan. Take the spell away and give it to Isabelle. The all meet in a public place. Isabelle brings her puppets and Elena brings the Salvatore brothers. Elena refuses to give her the device without knowing Jeremy is okay. Isabelle tells her to call home. She does and Jeremy is safe with Jenna and John. “How did you know Damon was going to give it to me?” “Because he’s in love with you.” Shock on Elena’s face, an attempted straight face and side eye toward Stefan on Damon’s, and somber acceptance on Stefan’s. Elena gives Isabelle the device and thanks her for being a monumental disappointment so the memory of her real mother stays in tact. “As long as you have a Salvatore on each arm, you’re doomed. Katherine was smart. She got out. But we all know that you’re not Katherine.” She turns away and watches Isabelle leave. Stefan and Elena hug and Elena looks at Damon before burying her face in Stefan’s chest. Stefan looks over at Damon after a moment. All the while, Damon is watching both of them before walking away.
Elena wants to talk to Jeremy, but Jeremy doesn’t want to talk. He does tell her he read her journal. Elena explains that when she had Damon erase Jeremy’s memory it was because it was like Mom and Dad all over again. She saw it in his face. He tells her to leave.
Isabelle shows up at the school with Alaric there. She wants to tell him goodbye. She wants him to hate her so it’s easier. He shows her that she’s wearing the ring. She’s shocked. Pretending she doesn’t care anymore. He gives her the ring back. He doesn’t believe she doesn’t care. So he gives her the ring back and drops her vervain on the ground. “I wanted this. I needed this. This was my mistake. Not yours. You are not going to remember this. I did. I loved you. I did. And when I think about what I gave up, it hurts. It does. But now you let me go.” She gives him the ring back and walks away.
Jeremy goes to his room and Anna is there crying telling him about her mother. “I know I’m not supposed to be here, but I don’t have anywhere else to go.”
Damon pours himself a drink in the parlor and offers one to Stefan. Stefan talks about what Isabelle said. He knows Elena cares about Damon and that he cares about her. Damon says they’re friends, in fact she’s like his only friend. He more or less threatens Damon. “This is not going to be like Katherine.” Damon puts two and two together about John being Elena’s father. John and Isabelle dated as teenagers. Isabelle confirms it. She calls John telling him she left the vampire stuff on his doorstep and tells him to kill Stefan and Damon. “I don’t want this life for her. She’s our daughter.” Oh snap! This show is getting crazier and crazier!
Without giving the details, Bonnie tells Caroline she didn’t remove the spell from the vampire weapon. She pretended to, but she couldn’t. Grams wouldn’t have done it, so she didn’t. “When Elena finds out, she’s never going to forgive me.”
