A new vigilante appears in Star City, known as "Vigilante", 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. D.A. 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 the bank robbers to lure in the Vigilante, who again escapes even after Oliver defeats and nearly unmasks him. Thea tells Oliver about Quentin and the possibility of his 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, Taiana's mother. He also claims that the Bratva has only been using Oliver for their own ends, including making a deal with him. Kovar then releases Oliver back to the Bratva.
