Here is the official episode description from the CW:
Episode Title: The Night of the Comet
As Mystic Falls prepares for a festival to celebrate the passing of a comet, Vicki (Kayla Ewell) is in the hospital recovering from the attack she can barely remember. Stefan (Paul Wesley) goes to the hospital and tries to use his abilities to make sure Vicki doesn’t remember what really happened, but his attempt is cut short when Vicki’s brother Matt (Zach Roerig) arrives. Jeremy (Steven R. McQueen) continues to struggle at school and with his feelings for Vicki. At a parent/teacher conference, Mr. Tanner (guest star Benjamin Ayres) makes Aunt Jenna (Sara Canning) feel that she is failing as a surrogate parent, especially when it comes to Jeremy. Elena (Nina Dobrev) decides to go to the Salvatore house to talk to Stefan, but finds his charming brother Damon (Ian Somerhalder) instead. Damon reveals surprising information about Stefan’s past, and when Stefan arrives home, Elena is confused and embarrassed to realize that he isn’t happy to see her there. Meanwhile, Vicki’s memory of the attack begins to come back to her.
