Complete story — includes the ending
Laurel tells Oliver about Emiko killing Diaz. Oliver finds Emiko and Dante stealing drones and confronts Emiko, who states that she owes Dante and the Ninth Circle for helping her when she was abandoned by her father. Using Archer, Team Arrow locates Dante and, when he seemingly believes Emiko has betrayed him, Oliver saves her and takes her back to the Arrow bunker. However, she escapes after being caught planting a jammer, which takes down Archer and allows the Ninth Circle to steal Sarin gas. Team Arrow tracks the Sarin drones to an airfield, where Oliver disables all but one of them, which gets away thanks to Emiko and releases the gas over an abandoned building. Emiko is revealed as the leader of the Ninth Circle and tells Dante about Archer. She also frames Laurel for killing an SCPD witness while releasing photos of her with Diaz to the press. Meanwhile, Felicity founds Smoak Technologies and hires Alena Whitlock as her CTO. Flashbacks show Emiko being abandoned by her father and meeting Dante. As an adult, she goes to her father for business help, but gets turned down, which leads to her staying silent about the explosives on board the Queen's Gambit.
