THE GIRL IN BLACK — After a series of strange encounters, Rebekah (guest star Maisie Richardson-Sellers) becomes intrigued by a mysterious girl who has recently arrived to the insane asylum. At the bayou, Hayley (Phoebe Tonkin) struggles with coming clean to Jackson (guest star Nathan Parsons) about the secrets she’s keeping and is surprised when he shares his own secret involving Hayley’s parents. Meanwhile, after learning the details of a particular marriage ritual that Hayley and Jackson must complete, Klaus (Joseph Morgan) heads to the bayou to put an end to it, but not before running into Jackson’s grandmother Mary (guest star Debra Mooney). Elsewhere, Vincent (guest star Yusuf Gatewood) remains determined to uncover the secret he knows Klaus is hiding and sets his eyes on Marcel (Charles Michael Davis) for answers. Lastly, when Davina (Danielle Campbell) discovers that Josh (guest star Steven Kruger) and Marcel are in danger, she enlists the help of Kaleb (guest star Daniel Sharman) and Aiden (guest star Colin Woodell) to rescue them.
