IT'S MY PARTY - On the morning of Elena's 18th birthday, Caroline is busy planning a party, but Elena is focused on searching for any clues that might help her discover where Stefan is. Damon is also searching for Stefan, while trying to protect Elena and keep her from doing anything that would draw Klaus' attention. Meanwhile, Klaus and Stefan are busy trailing a werewolf named Ray Sutton (guest star David Gallagher, "Super 8"). Now working at the Mystic Grill along with Matt , Jeremy is struggling to understand why he keeps seeing the ghosts of Vicki (guest star Kayla Ewell) and Anna (guest star Malese Jow) since he was brought back to life by Bonnie's magic. Meanwhile, Alaric does his best to watch over Elena and Jeremy, while dealing with his grief over Jenna's death. Finally, Caroline and Tyler face a new and unexpected challenge. John Behring directed the episode written by Kevin Williamson & Julie Plec. Klaus and Stefan hunt for werewolves so that Klaus can turn them into vampires in order to continue the breed of hybrids. Stefan and Klaus find out that Damon has been tracking them, so Stefan returns home and gives Damon a warning to back off by killing Andie, Damon's semi-compelled girlfriend. Meanwhile, Elena's 18th birthday arrives and Caroline holds a party for her. During the party, Jeremy sees the ghosts of "me and only me". Alaric, who has settled in as Elena and Jeremy's guardian after Jenna's death, decides to move out of their house, as he considers himself a bad role model. Caroline becomes jealous of Tyler's date Sophie at Elena's birthday party and compels her to leave. When Tyler confronts her about their issues, they kiss and go to Tyler's house. In the morning, Caroline attempts to leave the house quietly but is caught by Mrs. Lockwood, who shoots Caroline with vervain darts.
