The third episode of The Vampire Diaries season 4, “The Rager,” introduces Secret Circle‘s Phoebe Tonkin, and Stefan tries to cheer up Elena.

The Vampire Diaries‘ fourth season premieres in exactly one week, but you can now read the description of episode three, “The Rager.”

The CW has released the official synopsis, which gives us a lot of clues about what’s to come:

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.

A lot is revealed in this description: first of all, it seems Klaus has already got his body back by this episode! He is working with Damon against their common enemy, new character Connor, but for some reason Rebekah still feels isolated and alone. It is interesting that she should turn to April, a rumoured love interest for Jeremy.

And of course Phoebe Tonkin, best known for her role as Faye on The Secret Circle, arrives in town to stir up more problems for Tyler and Caroline. With their werewolf bond, will Faye be the Veruca to Tyler’s Oz (there’s a vague Buffy reference for you), or will Tyler and Caroline’s already tried and tested love survive yet another complication?
