Oliver, Diggle and Felicity privately track Prometheus, who starts killing seemingly random civilians with throwing stars. A news report on the killings causes tension in the city and angers the recruits, since they were not informed. Felicity steals one of the stars from Billy to examine. A pattern between the victims relates to Oliver's list from when he started out. This further angers the recruits, Evelyn most of all, as they did not know about Oliver's "kill list" from when he first returned. Felicity uses the pattern to predict future victims, and the team splits up. Evelyn encounters Prometheus and engages him, managing to cut his arm before being overpowered. Oliver then arrives, but Prometheus escapes. Meanwhile, Thea discovers that Quentin never quit drinking. Evelyn reconciles with Oliver, and Felicity tells Billy that she works with the Green Arrow, which intrigues him. She later tells Oliver that evidence she has discovered suggests that Prometheus could be an SCPD officer; Quentin is shown awakening from an alcohol-induced sleep with a slash across his arm and a throwing star in his possession. In flashbacks, during a Bratva operation, Oliver is abducted by Kovar's men and taken to him.
