Complete story — includes the ending
A new vigilante appears in Star City, one who kills criminals in cold blood. Quentin tenders his resignation as Deputy Mayor. He later tells Thea about the throwing star and his drunken blackouts, but believes he is being set up. The team intercepts the Vigilante during a bank robbery, but he gets away, as does Eric Dunn, the head of the robbers. District Attorney Chase forces one of the other robbers to reveal Dunn's location and Green Arrow saves him from the Vigilante. Thea convinces Quentin to go into rehabilitation, while Oliver and Susan start getting closer. The team poses as bank robbers to lure out the Vigilante, who again escapes even after Oliver defeats and nearly unmasks him. Thea tells Oliver about Quentin and the possibility of him being framed; they deduce that Prometheus must know Green Arrow's identity. Evelyn is revealed to be working for Prometheus. In flashbacks, Kovar introduces Oliver to his servant Galina Venediktov, Taiana's mother. He also claims that the Bratva have only been using Oliver for their own ends, including making a deal with him. Kovar then releases Oliver back to the Bratva.
