With his nightclub set to open and a new romance brewing with McKenna (guest star Janina Gavankar), Oliver is as happy as he’s been since returning to Starling City. But when Oliver’s ex, The Huntress (guest star Jessica De Gouw), suddenly returns to town, she threatens to destroy everything and everyone he cares about. Meanwhile, Laurel and her father struggle with the return of Dinah Lance (guest star Alex Kingston) who claims she has proof Sara is still alive. Thea gets Roy Harper (guest star Colton Haynes) a job at Oliver’s club, but he’s not too inclined to stop his life of crime. Oliver and Tommy are thrilled they were able to get Steve Aoki to play at the opening of their new nightclub, Verdant. David Ramsey and Susanna Thompson also star. Guy Bee directed the episode written by Jake Coburn & Lana Cho.
