CONTROLLING THE DEMON — When Eva Sinclair’s (guest star Maisie Richardson-Sellers) reemergence leaves Rebekah trapped and helpless, Klaus (Joseph Morgan) is forced to put aside his mistrust for Freya (guest star Riley Voelkel) in order to save Rebekah’s life. Meanwhile, Hayley (Phoebe Tonkin) and Elijah (Daniel Gillies) learn more about Eva’s violent past from Josephine (guest star Meg Foster), who then makes a startling revelation about Hayley’s future. With time running out to save Rebekah, Marcel (Charles Michael Davis) turns to a reluctant Vincent (Yusuf Gatewood) for his help to take down Eva, but his plan takes an unexpected turn, as Eva will not go down without a fight. Danielle Campbell also stars. Dermott Downs directed the episode written by Declan de Barra & Diane Ademu-John.
