Darhk begins taking control over the world's nuclear missles. The team seeks out Felicity's father, Noah, to help disable the "Rubicon" program. Darhk sends Danny Brickwell and Michael Amar to find and kill Noah, but Oliver and his team are able to rescue him from Darhk's men. Noah agrees to help, but requires a high-powered processor from Palmer Tech. Felicity learns she has been fired as CEO and is unable to get the processor, forcing the team to break in and steal it. H.I.V.E. locates the team when Noah hacks into "Rubicon". As H.I.V.E. attacks, Felicity and her father shut down "Rubicon" and stop all missiles but one, which launches and heads to Monument Point. Felicity can only redirect it to a less populated town, where it detonates. Oliver and Diggle find Darhk in a nexus chamber, gathering more power from all the deaths caused by the explosion. In flashbacks, Reiter escapes the caves, but Oliver and Taiana steal the idol again. The idol soon begins to affect Taiana.
