SummaryCOSTUME PARTY OF THE DAMNED - On campus, Elena is touched by a sad and secretive student named Aaron. Elena and Damon attend the Whitmore Historical Ball dressed as Anne Boleyn and Henry VIII. At the Ball, Elena shares a dance with Dr. Maxfield, who has a disturbing message for her. Caroline’s evening at the Ball takes her from happiness to heartbreak. Meanwhile, Nadia reveals her surprising history to Katherine, and Damon tries to make a deal with Silas. Silas demands that Damon commit an unthinkable act, which leads to a violent confrontation.
|After Professor Wes Maxfield killed Jesse at the end of the last episode, this episode starts with him making experiments on Jesse for unknown reasons and it seems that this is not the first one.
Meanwhile, Elena tries to deal with Bonnie's death so she tries to distract herself by going back to her research about Megan's death and why Professor Maxfield covered the reason she died. While she thinks how to get the information she needs, she sees someone at Megan's grave. She approaches him and asks him his name and if he knew Megan, but the man doesn't seem very willing to answer her questions. It is later revealed that the man's guardian is professor Wes and his name is Aaron. Wes asks him to stay away from Elena and then, on an encounter with Elena at the Whitmore Historical Ball, he tells her to leave college and go back to Mystic Falls with her friends because there are people on Whitmore who are watching her.
Tyler came back for Bonnie's funeral and he now spends some time with Caroline who still tries to convince him to stop what he is doing and come to college. Tyler informs her that he can't let Klaus get away from what he did to his mom and that he'll haunt him down and kill him. Caroline tries to change his mind with no luck so Tyler leaves and they break up.
Nadia still has Katherine captured and Silas tries to find them but he can't do it without his mental power. Katherine keeps asking Nadia what she wants from her and Nadia reveals her that she is her daughter who left behind in 1492 and the only reason she became a vampire was to find her.
In the meantime, Damon tells Jeremy his plan about how they can bring Bonnie back to life. Since to bring someone back someone else has to die, he says that they should take advantage the fact that Silas wants to die to be with his true love, Amara, so that Bonnie comes back. They have to work with Silas though to do that and Bonnie doesn't agree with the idea, but Jeremy tells Damon that she's fine with it. Damon meets Silas to inform him about his plan and Silas agrees but he puts his own term; he wants Damon to "kill" his brother. By "killing" Stefan, the link between the two of them will be broken and Silas will have his mental power back. Damon just has to keep Stefan "dead" as long as Silas will be pretending to be Stefan so he can get the information he needs from Qetsiyah's head.
The plan goes well until the moment Stefan escapes from Damon before he "kills" him again and lets Qetsiyah know that she is talking to Silas and not him. Qetsiyah gets mad, reaches into his heart and twists it while she is making a spell causing it to stop. The spell turns Silas cold and grey and unable to move or do anything, but not dead. Damon and Elena find him and take him back to the Salvatore house.
Katherine arrives at Salvatore house after Damon called her and she is happy seeing that Silas is gone. The reason though Damon called her was to use her and bring Silas back so he feeds her to Silas. Silas starts waking up and while Katherine should be dead after this, she also wakes up with Elena and Damon not knowing why.
- Antagonists: Silas and Wes.
- This episode marks the first appearance of Aaron.
- It is mentioned that three days have passed since the previous episode.
- Elena meets Aaron in this episode and uses compulsion to ask him if he killed his friend Megan. After Aaron confesses that everyone he knows has died, Elena starts to feel a kinship with him as a result of their shared survivor's guilt.
- Wes tells Aaron to stay away from Elena, but doesn't clarify as to why he should do this.
- Wes is also revealed to be Aaron's legal guardian.
- The Whitmore Historical Ball takes place in this episode, and the attendees all dressed in historical-themed costumes.
- Elena and Damon dressed as Anne Boleyn and Henry VIII.
- Caroline and Tyler dressed as Bonnie and Clyde.
- Qetsiyah/Tessa dressed as Cleopatra.
- Stefan dressed as James Dean (though, as Caroline pointed out, his costume was really only jeans, a white tshirt, and a black leather jacket.) Silas purposely dressed like Stefan to better impersonate him.
- Elena is told by Wes to drop out of school at Whitmore College and move back to Mystic Falls before cryptically warning her that she and her friends are being watched by the higher-ups on campus. He then alludes that if she isn't careful, they may start "asking the right questions" about her.
- Tyler and Caroline break up in this episode after Tyler confesses to Caroline that he can't stay at Whitmore because he needs to seek vengeance against Klaus for his mother Carol's murder.
- Jesse awakens in transition to find he is tied to a gurney by Wes in his laboratory. Wes also states in his audio notes that Jesse's test subject number is 62547.
- Nadia finally reveals to Katherine that she is the daughter she had out of wedlock and was forced to give away in 1490.
- Afterward, Katherine asks Nadia where she was in 1498 and reveals that after being on the run from Klaus for six years, she returned to Bulgaria and searched every village to try to find her.
- Silas and Damon make a deal to ensure that each of them get what they needed—Damon promises to help him obtain the cure (which is in Katherine's blood) if Silas promises to use his eventual death to resurrect Bonnie before he destroys the Other Side.
- Though Stefan still has no memories of his life or relationships as a result of Tessa's linking spell, he still managed to bond with her at the ball, and ultimately goes home with her so the two can continue partying together.
- When Stefan awakens after having his neck snapped by Damon and informs Tessa of Silas and Damon's plans, Tessa becomes so angry that she uses her recently-found talisman to desiccate Silas once again.
- At the end of the episode, Damon force-feeds Katherine's blood to Silas, both to reawaken him from his desiccated state and to fulfill his end of their deal by curing him of his immortality and returning him to his original witch status. Elena was aware of Damon's plan to feed Katherine to Silas, and though it was clear she did not necessarily approve of his methods, she still did nothing to stop him because she was also desperate to bring Bonnie back.
- Despite Katherine being almost completely exsanguinated, she still manages to keep her heart beating long enough to survive curing Silas with her blood.
- Only two promotional images were released prior this episode. The last time this was the case was Plan B.
- Elena has a new diary and has once again started writing again in order to help her process Bonnie's death. While she wrote the day's entry in it, Bonnie stood behind her in her ghost form and watched her cry.
- Matt doesn't appear in this episode. However, he does appear in a deleted scene from this episode, where he spends most of it being controlled by Gregor, the Traveler possessing him, before briefly regaining consciousness.
- In the same deleted scene, Nadia reveals that she was once a Traveler, but she lost her magic when she voluntarily turned herself into a vampire to make it easier for her to track Katherine down.
- In another deleted scene, after Katherine successfully calls Matt forth from inside his mind to take back control of his body, she explains that she knew the "codewords" to the Passenger spell because Nadia's father was also a Traveler and taught it to her.
- However, in Dead Man on Campus, Katherine tells Nadia that her father (Mr. Petrova) was a Traveler, which is why she knew what Gregor's blade could do. While it could be that the writers decided to change Nadia's history by having her inherit her Traveler witch status from her maternal grandfather instead of her biological father, it is also just as likely that Nadia gained her Traveler heritage from both sides of her family tree—in Fifty Shades of Grayson, Katherine told Nadia that her father referred to Traveler magic as "the devil's work" and that he purposely made it sound terrifying so she and her sister wouldn't be tempted to practice it. This would explain why Katherine stated in the deleted scene that she learned the "codewords" from Nadia's father, since it is unlikely that her own father would want to teach her anything related to Traveler magic.

- Damon: (tries to lighten the mood) "Guilt. Don't know it, but I've heard it can be a real bitch."
- Elena: "I know that it's not my fault that Bonnie died, but it is my fault for not figuring it out sooner."
- Damon: "Elena, you are allowed to be happy once in a blue moon. Besides, Jeremy has been lying to us all summer."
- Elena: "I should have figured It out, Damon! I know that It's not the same, but I'm not 'gonna let Megan's death fall through the cracks too..."
- Caroline: "Oh, before I forget. I talked to the register and your major is... drum roll... geosociology."
- Tyler: "How about... we don't talk about the major right now."
- Caroline: "And I compelled you a single."
- Tyler: "Definitely don't wanna talk about my dorm room."
- Caroline: "Or we could talk about the hybrid-sized jerk that you've been for not calling me back. Ever."
- Tyler: "How many times do you want me to tell you. I've been helping a werewolf pack in the land of no cell phone reception."
- Caroline: "Well, lucky for you, I figured out a way for you to make up for it."
- Tyler: "I thought I did make up for it. A couple of dozen times."

- Nadia: "It's not a game, Katherine. You did kill my mother, but it wasn't in Paris. It was in a little cottage in England, and it wasn't 1645. It was April 6, 1492, and she was all alone, exiled by her family two years earlier. You stuck her head in a noose, pushed her off the chair, and snapped her neck."
- Katherine: (stunned) "Who are you?"
- Nadia: "My name... is Nadia Petrova... And you are my mother."
- Silas: "You love me. You know you love me."
- Tessa: "I did love you. And then you broke my heart, and now I'm gonna break yours. Or at least stop it from working, so your blood can't flow and your veins dry up and you rot from the inside out. Sp the world can see you exactly as you are-- a cold, gray, hideous monster."
