On the next episode of The CW's VAMPIRE DIARIES titled 'O Come All Ye Faithful,' as a Winter Wonderland-themed party fills the streets of Mystic Falls, Stefan and Caroline find themselves at odds with Tyler over his plans for Klaus and his hybrids. When Caroline proposes a solution to their problem, Hayley (guest star Phoebe Tonkin) finds a dramatic way to make it clear that she is not on board. Later, Klaus makes a discovery that leads to chaos and violence.

Meanwhile, Elena and Damon retreat to the Gilbert Lake House to help Jeremy conquer some dangerous inner demons with the help of Bonnie and Professor Shane (guest star David Alpay), who reveals a piece of ancient history that leaves them all speechless. Zach Roerig also stars. Pascal Verschooris directed the episode written by Michael J. Cinquemani & Julie Plec. The episode airs Thursday at 8 pm/ET on The CW. Get a sneak peek below!

Returning for its fourth season, THE VAMPIRE DIARIES is the story of two vampire brothers, obsessed with the same girl, in a small town where supernatural beings live in secret amongst its residents. In season one, Stefan (Paul Wesley) and Damon Salvatore (Ian Somerhalder), returned to their hometown of Mystic Falls, Virginia, for very different reasons. Stefan was determined to get to know Elena Gilbert (Nina Dobrev), who bears a striking resemblance to Katherine Pierce (also played by Dobrev), the beautiful but ruthless vampire the brothers knew and loved — in 1864.

Damon, on the other hand, was intent on releasing Katherine from the tomb where he believed she was trapped by a witch’s spell all those years ago. The explosive season finale set a plan in motion that resulted in Katherine’s return.
