The actress joins Joseph Morgan as Klaus and Daniel Gillies as Elijah, all of whom have been recurring on The Vampire Diaries since Season 2. These siblings are the last surviving members of the first vampire clan ever to walk the Earth. Phoebe Tonkin will also appear as Hayley, along with Daniella Pineda and Danielle Campbell as the witches Sophie and Davina. Leah Pipes has also joined the cast as a human psychology student.
Julie Plec wrote the pilot script, which will air as an episode of The Vampire Diaries on April 25. The story will follow Klaus back to his old stomping grounds in the French Quarter of New Orleans, which he helped build centuries prior. He meets up with his former protege Marcel (Charles Michael Davis), while Elijah realizes he must side with Marcel's enemies to keep Klaus under control.
