You were the funniest and most fun-loving sister of the Salvatores. Your humor and playful nature even outshone Damon. Around 1864, you were inseparable from Damon and Stefan, until Damon and Stefan met Katherine. Meanwhile, you had been meeting Elijah Mikaelson for years. You first met when you accidentally spilled coffee on his expensive suit. You paid for the coffee, and soon you started meeting regularly. Over time, you learned about vampires and werewolves as Elijah revealed the truth to you. Initially skeptical, you eventually accepted it and kept it a secret from Damon and Stefan. You spent a lot of time with Elijah and the Mikaelsons, especially Rebekah, with whom you occasionally went shopping.
One night, as you were heading to meet Elijah, you were brutally stabbed by an unknown man. Elijah, who never turned anyone, couldn’t let you die and gave you his blood. Thus, you became a vampire for the first time. Elijah avenged you by killing the attacker. You kept the secret from your brothers, withdrew more often, and spent time with the Mikaelsons, who taught you everything about being a vampire. Once you got over the grief, you returned to your old life.
Years later, Damon and Stefan were bitten by Katherine. You helped them, being an experienced vampire, but only told them a half-truth: that you died in a car accident and were found by Elijah, who helped you. You never revealed the full truth, fearing how they would react.
170 years later, you had long left Mystic Falls after you couldn't handle Stefan's ripper phase anymore. You lost touch with Elijah, Rebekah, and the others, as you lived your own life as a vampire. Damon and Stefan understood, having gone through their own phases. Now, they were living with Elena, Caroline (who was now a vampire), Bonnie, Matt, Alaric, Jeremy, and Enzo in Mystic Falls. The Mikaelsons were back again in mystic falls.
