Then let me say it. I've been so selfish because I love you so much and I know how much you love me. But it's over. Stefan, it has to be. [...] It doesn't matter, Damon. She won. Katherine won.
Elena to Stefan and then to Damon

Bonnie accidentally discovers new information about Mason and shares it with Stefan, leading Damon to take matters into his own hands.



Main Cast

Recurring Cast



  • Antagonist: Katherine Pierce.
  • This is the first episode this season to feature all the main characters in it.
  • This episode marks the death of Mason, whose story-arc was wrapped up in six episodes, much like Vicki from last season, who also appeared in the first seven episodes, only to wind up dead as well. The difference is that Vicki was a main character, whereas Mason was a recurring character.
  • This is the third episode this season to end on a cliffhanger that features Katherine using a character for her future plans: Caroline (Bad Moon Rising), Mason (Kill or Be Killed) and Matt.
  • Though Matt is under Katherine's control she doesn't have sex with him as revealed in Gone Girl.
    • Katherine tells Matt in Gone Girl that he's the best night she never had unless this was said for her daughter Nadia's benefit who may have been watching from the Other Side.
  • This episode includes a reference to the novels with the well and Mrs. Flowers.
  • This episode marks the temporary end of Stefan and Elena's romance, as Elena breaks up with Stefan after Katherine nearly kills Jenna in retaliation, not wanting anyone else to get hurt because she wanted to stay with him.
  • Mason meets Bonnie in this episode.
  • Damon tortures and kills Mason. Mason's death marks the first werewolf to be killed by a vampire.
    • This also marks the second time heart extraction has been used as a method to kill supernatural species. The first time this was used was in Season One's Bloodlines, when Damon ripped out Bree's heart for betraying him.
    • The manner of Mason's death will later be referenced in Season Three's Ghost World, when a spell gone wrong allows ghosts with unfinished business to gain a physical foothold in the living world from the Other Side. Mason then tortures Damon by binding him to a chair with chains and running a fireplace poker through his chest, similar to how Damon killed Mason in this episode.
  • Only two promotional pictures were released for this episode.
  • When Caroline compels Liz to forget about vampires, she only mentions herself, not Damon and Stefan.
    • However, it can be assumed that Caroline included the necessary details off-screen, as Liz did not appear to know about Caroline, Damon, or Stefan's true identities as vampires again until the episode Know Thy Enemy, when Matt admitted to Liz that he had learned Caroline was a vampire.



  • Bonnie and Matt were last seen in Bad Moon Rising.
  • Liz is compelled by Caroline to forget that Stefan, Damon, and herself are vampires. This compulsion will held until Know Thy Enemy, when Matt learns that Caroline is a vampire and tells Liz before he can be compelled as well.

Cultural References

  • Indiana Jones: is a fictional professor, archaeologist and adventurer. He was first seen in the 1981 movie, Raiders of the Lost Ark.
  • Kill or be Killed is a common catch phrase in many genre movies and series, including Buffy the Vampire Slayer.
    • The common usage today is often credited to Jack London's The Call of the Wild: “He had learned well the law of club and fang, and he never forewent an advantage or drew back from a foe he had started on the way to Death. He had lessoned from Spitz, and from the chief fighting dogs of the police and mail, and knew there was no middle course. He must master or be mastered; while to show mercy was a weakness. Mercy did not exist in the primordial life. It was misunderstood for fear, and such misunderstandings made for death. Kill or be killed, eat or be eaten, was the law; and this mandate, down out of the depths of Time, he obeyed.

Behind the Scenes

Katherine: "Mason? You should've been here an hour ago."
Damon: "Wrong boy toy."

Damon: "Mason? Oh, he's right next to me, if you want us to send him over... Except his heart's on the other side of the room."
Katherine: (furiously) "You shouldn't have."

Jeremy: "It's gonna be okay."
Elena: "No, it's not."
Jeremy: "She's gonna pay, Elena. I don't know how, but she's gonna pay."

Jeremy: "Damon..."
Damon: "You wanted to be a part of this? Well, here it is. Kill or be killed. The guy’s a werewolf. He’d kill me the first chance he got! So you suck it up, or leave. He wants me to kill him, anyway. Don’t you, Mason? It really is a curse, isn’t it? You know, I look at you and I see myself. A less dashing, less intelligent version."
Mason: "I love her."
Damon: "Oh, I know! I’ve been where you are. But Katherine will only rip your heart out. Let me do it for her."

Stefan: "You’re staring."
Elena: "I’m gazing."
Stefan: "It’s creepy."
Elena: "It’s romantic."

Damon: (to Jeremy) "Kill or be killed. You either suck it up, or leave."
