The CW has released the official synopsis for The Vampire Diaries: The Rager (EP403), airing Thursday, October 25th. Highlight for spoilers:
BORN TO BE WILD — Connor (guest star Todd Williams) continues his search to uncover the secrets of Mystic Falls and tries to convince Jeremy (Steven R. McQueen) to work with him. With Dr. Fell’s (guest star Torrey DeVitto) help, Damon (Ian Somerhalder) and Klaus (Joseph Morgan) question Connor, but the confrontation takes a lethal turn. Trying to keep her new life as normal as possible, Elena (Nina Dobrev) is determined to continue her senior year at Mystic Falls High with support from Matt (Zach Roerig) and Caroline (Candice Accola). Rebekah’s (Claire Holt) arrival at school makes it difficult for Elena to control her anger, but she learns that confronting Rebekah can be extremely dangerous. Later, Rebekah realizes how alone she is, and reaches out to April (guest star Grace Phillips). Stefan (Paul Wesley) takes Elena on a thrilling motorcycle ride in an effort to show her that life can still be fun. Tyler (Michael Trevino) gets a surprise visit from Hayley (guest star Phoebe Tonkin, “The Secret Circle”), a werewolf who helped him through the ordeal of breaking his sire-bond to Klaus. Concerned about Elena, as well as his own emotions, Stefan turns to a sympathetic Caroline for advice.
The episode was written by Brian Young and directed by Lance Anderson. This also marks the first episode of guest star Phoebe Tonkin!
