Read the official synopsis for The Vampire Diaries‘ first episode back in January 2013, titled “After School Special.”

The CW has released the following information about the episode:

REBEKAH IS BACK WITH A VENGEANCE — Appearing unexpectedly at Mystic Falls High, Rebekah (Claire Holt) wastes no time trying to force Stefan (Paul Wesley), Elena (Nina Dobrev) and Caroline (Candice Accola) to answer her questions about the search for a cure, leading to a bombshell piece of information from Elena.

When Bonnie’s (Kat Graham) father, Rudy Owens (guest star Rick Worthy, ‘Supernatural’), accepts the role of Interim Mayor, he makes it a priority to protect his daughter, who isn’t at all comfortable with the role he suddenly wants to play in her life. Professor Shane (guest star David Alpay) continues to encourage Bonnie to believe in her powers, but he soon finds himself in danger when he reveals too much to the wrong person. Later, Caroline does her best to comfort Tyler (Michael Trevino) after a violent confrontation.

Meanwhile, at the lake house, Damon and Matt (Zach Roerig) train Jeremy (Steven R. McQueen), trying to raise his game as a hunter, but Klaus (Joseph Morgan) is impatient with their progress and intervenes to speed up the process.

David Von Ancken directed the episode written by Brett Matthews (#410).

Further, Joseph Morgan has spoken to TV Guide about what we can expect to see from Klaus in the second half of season 4, and also reveals that Kol (the other Original brother) will be back in Mystic Falls.

He also hints that even though Klaus is at something like his most evil right now, “Our heroes are at odds with each other. If they could unite themselves like they did at the end of season 3, maybe they would have a chance [at killing Klaus], but as long as he can keep manipulating and planting doubt in their minds, they won’t be able to come together and defeat him.” Good news for Klaus fans!

The Vampire Diaries returns on January 17 at 8/7c on The CW.

Are you as excited for Rebekah to come back as we are?!
