Alexia "Lexi" Branson was a vampire and Stefan Salvatore's best friend and companion. She had known Stefan and his brother Damon for over a century. Damon killed her to make the Town Council think that she was the vampire terrorizing Mystic Falls. Lexi returned as a ghost to help save Stefan. She returned as a ghost again however this time Stefan was delighted to see her. She later choked Damon for killing her but let him go. She and Stefan stayed together for the most part drinking and later parting on good terms. Through flashbacks we learn years ago when Damon was in New York killing people and gaining a reputation as "Son of Sam", Stefan sent Lexi to "help" Damon. For about 6 months they hung out and got wasted then every night Lexi would ask Damon about Katherine, trying to help him remember love. One night Damon "confessed" that he didn't love Katherine anymore and that he had flipped his switch and had fallen for Lexi and they had a night of wild sex, "On the bar, the stage and eventually the roof". The next morning the sun came up and Lexi tried to run inside but the door was bolted and Damon woke up and said he had to be really quiet so she wouldn't hear him revealing that he set her up and didn't care about her and instead was punishing her for the last 6 months.
