Complete story — includes the ending
Carrie Cutter returns to Star City and begins targeting high profile couples. While the team works to track her whereabouts and prevent any more killings, Laurel works on Darhk's prosecution. After several failed attempts to find a suitable witness, Quentin testifies to his involvement. The team discovers that Carrie is targeting couples that have recently been married. In order to draw her out, Oliver convinces Felicity to stage a "secret" wedding with him to set themselves up as targets, intentionally leaking the information to the media. The plan works and Carrie attacks Oliver and Felicity at the ceremony. Felicity distracts her long enough for Diggle and Thea to apprehend her. Darhk's bail is denied and is remanded into custody. Quentin is suspended pending an investigation, while Felicity quits the team for good. In custody, Darhk is shown wearing a mystical ring he secretly carried inside. In flashbacks, Oliver leads Reiter to a mystical idol, but steals it and runs off into the tunnels with Taiana. The pair incapacitate two mercenaries and acquire their guns.
