Modern Family

It is four months after a tragic car accident killed the parents of 17-year-old Elena and her 15-year-old brother, Jeremy, who are still adjusting to this new reality and living with their Aunt Jenna. Elena finds some comfort with best friend Bonnie and frenemy Caroline while trying to sort out her feelings for former boyfriend Matt, but Jeremy is hard-pressed to find the same comfort, instead hanging out with a bad crowd and trying to figure out why Matt's sister, Vicki, is suddenly rejecting him to be with his rival, Tyler.

As Mystic Falls prepares for a festival to celebrate the passing of a comet, Vicki is still in the hospital, recovering from the attack she can barely remember. Stefan goes to the hospital and tries to use his abilities to make sure Vicki doesn't remember what happened, but his attempt is cut short when Vicki's brother, Matt, arrives. Jeremy continues to struggle at school and with his feelings for Vicki. At a parent/teacher conference, Mr. Tanner makes Aunt Jenna feel she is failing as a surrogate parent, especially regarding Jeremy. Elena decides to go to the Salvatore house to talk to Stefan but finds his charming brother, Damon, instead.

Elena tries to ignore Bonnie's warnings about the disturbing vibes she got from Stefan. Tyler tries to embarrass Stefan by throwing a football at him, but Stefan effortlessly catches and passes the ball back, impressing everyone with his skill. Mr. Tanner reluctantly lets Stefan join the football team. Elena invites Stefan and Bonnie to dinner, hoping that the two will bond, but the unexpected and unwelcome arrival of Damon and Caroline disrupts the evening. Plus, the town is shocked by an act of violence.

Elena asks Stefan to escort her to the town's annual Founder's Party. Vicki gets Tyler to ask her to the party, and then accuses him of trying to hide their relationship from his family. Zach reveals a useful family secret to Stefan. At the party, Damon tells Elena a story about the Salvatore family's past, leaving Elena with questions that Stefan refuses to answer. Finally, Stefan takes action to get Damon out of his life for good.

Stefan is hopeful that his plan to get rid of Damon is working, and decides to reveal parts of his past to Elena. Meanwhile, Elena and Jenna are concerned about Jeremy's relationship with Vicki. At a fundraising car wash, Bonnie is surprised by abilities she didn't know she possessed and seeks advice from her grandmother. Finally, Elena hears a disturbing story about the Salvatore family from a stranger.

Elena demands that Stefan explain the frightening events that have been happening in Mystic Falls. In flashbacks, Stefan explains how his rivalry with Damon began. Back in the present, Damon impulsively takes control of Vicki's future, and a confused and frightened Vicki runs away. Sheriff Forbes and Mayor Lockwood take steps to protect the town.

As Vicki's behavior becomes more dangerous, Stefan tries to help her. Elena, meanwhile, tries to convince Jeremy to stay away from her.
