Storylines The season begins after the deaths of Elena and Jeremy Gilbert's parents. Both are put in their Aunt Jenna's custody. Jeremy has become a loner and Elena starts dating a boy named Stefan Salvatore. It is soon revealed that Stefan is a vampire and his brother Damon shows up in Mystic Falls and kills people at random. Another supernatural revelation occurs when Elena's friend Bonnie Bennett discovers she is born into a line of witches and is a witch herself. She gets help from her grandmother to use her powers.
