Fans of "The Originals" will have to wait until the end of the month to find out what will happen to Rebekah and Klaus, who were captured by the evil witches.

In the last episode, the witches wreaked havoc on the Crescent werewolves and the vampires in New Orleans. Klaus was also lured into a trap and stabbed by Sophie with Papa Tunde's powerful bone knife, before she was killed by her niece Monique, reports The Vampire Dairies.

The next episode, "Long Way Back from Hell," won't air until Feb. 25, but from the looks of the promo video, it seems to be intense.

In the video, Klaus and Rebekah are seen being tortured by Celeste and the witches in what appears to be an abandon mental institution. Rebekah suffers from terrifying hallucinations and Klaus finds himself chained by the neck and forced to endure horrible psychological and physical torment. While there, Rebekah also gets a blast from the past from Genevieve who returns to threaten her and potentially expose some of her big secrets, reports WetPaint.

In the meantime, Elijah intuitively realizes that he needs to rally his forces to save his siblings from their horrible predicament. The clip then ends with Genevieve saying, "Just because we can't kill them doesn't mean they can't be destroyed."

Executive producer Julie Plec revealed to TVLine that the next episode "is actually really crazy." She continued saying, "We go outside of the Quarter, and we put Rebekah and Klaus into a trapped situation in a creepy, horrible, messed-up sanatorium back in the day. Genevieve, working between the two of them, enacts her revenge, and we'll learn why Genevieve's revenge is so specifically targeted towards Rebekah and what exactly she's going to do to make Rebekah suffer as much as possible." She added that "the outcome of what the witches do to our Original family will have eternal repercussions for their dynamic."

The EP also teased that we have not seen the last of Thierry. According to Plec, the vamp will resurface later this season and could possibly "come in handy to one of our characters," reports TVLine.

The CW released a full synopsis for the Feb. 25 episode which reads: "When Rebekah (Claire Holt) finds herself locked up in the sanatorium where she worked in 1919, she realizes a witch named Genevieve (guest star Elyse Levesque) is back to seek revenge and to reveal dark secrets that would destroy Rebekah if exposed. A distraught Elijah (Daniel Gillies) turns to Marcel (Charles Michael Davis) and Hayley (Phoebe Tonkin) for help when one of his decisions puts Klaus (Joseph Morgan) and Rebekah's lives in danger. With time working against them, Marcel realizes he may hold valuable information that could lead them to Rebekah and Klaus, but revealing it will almost certainly result in deadly consequences."

"The Originals" S1E14, "Long Walk Back to Hell," airs Tuesday, Feb. 25 at 8 p.m. on the CW.
