The Originals: 1x15 Le Grand Guignol Stills

Rebekah and Marcel’s biggest secret was revealed in the last episode of The Originals. A former friend turned enemy of Rebekah’s had trapped Rebekah and Klaus inside of a former hospital and exposed her secret to Klaus that she and Marcel had summoned Mikael to New Orleans many years ago so that they could be free of the hybrid and be together. The pair have been keeping this secret for almost 100 years, but now Klaus has vowed to destroy them after learning about the betrayal. Fortunately for them, Elijah intervened and stabbed his brother, allowing Rebekah and Marcel to escape.

But in the next episode, the pair are on the run as Klaus recuperates and he’s still determined to hunt them down. Will they leave town? Here is what’s in store: “In a series of flashbacks to 1919, Klaus (Joseph Morgan) opens up to Cami (Leah Pipes) and reveals details of the devastating secret Rebekah (Claire Holt) and Marcel (Charles Michael Davis) were trying to keep from him. Elijah (Daniel Gillies) forms an unlikely alliance with Monique (guest star Yasmine Al Bustami) and asks for her help in locating Sabine (guest star Shannon Kane.) Elsewhere, Thierry (guest star Callard Harris) is reluctant to get involved when Marcel and Rebekah approach him with a plan to take down the witches. Meanwhile, in the bayou, Hayley (Phoebe Tonkin) is at her wits’ end and holds Sabine hostage in an attempt to get information that will reverse the curse on Phoebe’s werewolf clan.”
