Caroline Forbes is a vampire and one of the main female characters on The Vampire Diaries. Caroline is the daughter ofWilliam Forbes II and Sheriff Elizabeth Forbes. She is also the surrogate mother of Alaric and Jo's twin daughters Lizzie Saltzman and Josie Saltzman. Prior to her transition into a vampire, she was known for her insecurities, which caused her to be excessively competitive, mainly with Elena.
She has always had a strong bond with her childhood friends,Elena Gilbert and Bonnie Bennett. She became best friends withStefan Salvatore after she became a vampire and he became her mentor. She is also close friends with her ex Matt Donovan whom she has known since childhood, and also with Niklaus Mikaelson.
Earlier in the series, Caroline begins dating Elena's ex-boyfriend, Matt, who encourages her to become more caring, kind, and selfless. In the Season One finale, Caroline was severely injured in a car wreck and suffered from internal bleeding.
Because Caroline's situation was looking pretty bleak, Bonnie and Elena agreed that Damon Salvatore should heal Caroline by feeding her his blood. Later, after Caroline's health had improved, Caroline was smothered to death in the hospital by Katherine Pierce, who was aware that Damon had healed Caroline, therefore knowingly turned her into a vampire. Katherine planned to use Caroline to her own advantage by manipulating her and eventually giving her to Klaus to kill in the sacrifice. Damon rescues her and Tyler Lockwood, however, and the deal made by Katherine is forfeited.
She attended Mystic Falls High School, where she was the captain of the cheerleading squad, honor student, head of the dance committees, Mystic Falls beautification committee, head of the recycling program, "Go Green" campaign, Miss Mystic Falls, and one of the most popular girls in the school. She later attendedWhitmore College with Elena and Bonnie.
