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).
