Promise me something, both of you. Write it all down, everything that you accomplish in your lives, every crush, when you fall in love, when you start a family, every time you fantasize about wanting to kill Damon. Write it down so that one day when I wake up I can read all about my best friends' lives and feel like I was there.
Elena to Caroline and Bonnie in I'm Thinking Of You All The While

This is the sister-like relationship between the cured vampire/human doppelgänger Elena Gilbert, the vampire Caroline Forbes, and the witch Bonnie Bennett.

Elena and Bonnie were originally best friends, while Caroline was closer to Bonnie, mainly due to being jealous of Elena. After Caroline's transformation into a vampire, her friendship with Bonnie deteriorated for a short time, but Elena was there for her, strengthening their friendship. Bonnie later accepted Caroline the way she was, and they quickly rekindled their close friendship. Unfortunately, on the night before graduation, Bonnie desperately attempted to bring Elena's brother Jeremy back to life using spirit magic, dark magic, and Expression magic all at the same time, and ultimately died from overuse of magic. Not wanting to hurt Caroline and Elena, Bonnie, as a ghost, forced Jeremy to keep her death a secret for the entire summer. Because the veil was down when Bonnie died, Bonnie was able to graduate with her friends with no one else the wiser. Once Caroline and Elena learned of Bonnie's death, they worked tirelessly to find a way to bring her back, eventually convincing a witch to give Bonnie the power to be the Anchor to the Other Side, allowing her to be a corporeal ghost so she could continue to live as a normal human would, though she also acted as a tollbooth to the Other Side, which brought complications.

After Markos tore his way out of The Other Side, it began falling apart, which not only threatened the residents of the supernatural purgatory with permanent extinction, but also Bonnie, as the Anchor. Once again, Bonnie attempted to keep Elena and Caroline from knowing about her imminent demise, though they eventually did find out and tried their best to stop her. In the end, they failed, as the Other Side completely collapsed and destroyed itself, taking Bonnie and Damon into 1994 Prison World.

After the events in Season Five, Elena and Caroline struggled to move on without Bonnie and Damon, however, Damon came back during Season Six, thanks to Bonnie. This motivated Elena, Caroline, and the rest of their friends to help bring Bonnie back from the Prison World Bonnie was stuck in. Eventually, Bonnie got out of the Prison World and reunited herself with Elena and Caroline shortly after reuniting herself with Damon first. Bonnie was surprised to find Caroline with her humanity off due to the death of her mother, but this barely effected their friendship and it more so effected and strained Elena and Caroline's friendship. Caroline finally turned her humanity back on after some help from Stefan, Elena, and Damon. Things were starting to look up, until Kai Parker came back with the new group of Heretics, witch-vampire hybrids that were brutal killers sent to another Prison World nearly a century ago. Due to Kai Parker wanting revenge on Bonnie for leaving him in another Prison World with the Heretics earlier in Season Six, Kai spelled Elena into a lifelong slumber and linked her life to Bonnie. When Bonnie dies a natural death, Elena would awaken. However, any spell or loophole Bonnie or the others tried to wake Elena up, it would kill both Bonnie and Elena. This forced Bonnie, Caroline, and the others to say goodbye to Elena. Caroline and Bonnie were forced to carry on without their best friend, Elena, during Season Seven.

Throughout The Vampire Diaries Series




  • Before and after Elena's second death as a human, all three of them were different kind of supernatural creature.
  • Elena, Bonnie, and Caroline have all died at least once at some point in the series. Elena has died three times, Bonnie has died four times, and Caroline has died once.
    • Caroline died in The Return when Katherine smothered her with a pillow. She returned in Brave New World as a vampire.
    • Bonnie died in The Last Dance when Klaus seeming forced her to use too much magic trying to kill him. However, she had really cast a spell to mimic death, allowing her to appear dead to Klaus, and magically return to life later in the same episode.
    • Elena died in The Sun Also Rises when Klaus drank her blood. She returned in the same episode thanks to a spell Bonnie had cast that allowed John Gilbert's life force to resurrect her, at the cost of his own life.
    • Elena died in The Departed when Rebekah caused Matt's truck to crash into the river, leading her to drown. She returned in the same episode as a vampire.
    • Bonnie died in Growing Pains from using dark magic to temporarily stop her own heart so she could travel to the Other Side and return Elena's soul back into her body. Unfortunately, she was stopped from completing the spell by the ghost of her Grams, and she returned to life through the spell in the same episode.
    • Bonnie died in The Walking Dead when she used too much magic at once to resurrect Jeremy. She was later brought back to life, in a sense, when she was made a corporeal ghost as the Anchor to the Other Side in Death and the Maiden.
    • Elena died again in Home, when she and Damon were blown up in an explosion as part of their plan to sacrifice dozens of Travelers to bring their friends back to life from the Other Side. She returned to life as a vampire after passing through Bonnie, just as they planned.
    • Bonnie died for the fourth time in Home when the Other Side finally imploded. She was surrounded by a white light as she and Damon were presumably sucked into another dimension.

  • Matt told Katherine (while she was possessing Elena's body using a Passenger spell) that Elena likes both Caroline and Bonnie equally.
  • Out of the three, Bonnie has died the most and Caroline has died the least.
  • Elena and Bonnie have been victims of possession by Katherine Pierce and Emily Bennett, while Caroline hasn't
    • Ironically both girls were possessed by an ancestor from their own bloodline.
  • At Bonnie's memorial, both Elena and Caroline comfort one another.
