Unpleasantville (2010)

As Stefan and Damon try to figure out the identity of the new vampire in town, Stefan gives Elena more vervain-filled jewelry to protect her family and friends. Strapped for money, Matt takes a job as a busboy at the Mystic Grill, where former high school football-star Ben works as a bartender. Ben comes to Bonnie’s aid when he notices Damon is bothering her. Damon and Stefan accompany Elena to a school dance with a 1950s theme, where Alaric introduces himself to Damon. The vampire that has been stalking Elena is killed by Stefan and Damon. Before dying, he reveals that the way to get into the tomb lies in the Gilbert journal. While Jenna and Alaric are walking home from the party, Alaric tells Jenna that his wife was named Isobel, the same name as Elena's birth mother. Meanwhile, Anna keeps on trying to get close to Jeremy, because she wants to get her hands on his ancestor's journal. At the end, it is revealed that both Anna and Ben are vampires and appear to be romantically involved with each other.
