Stanley is happy to have Oliver back and informs him, Diaz's henchman has been sent to Level 2. Stanley tells Oliver that Brick was the one who paid those men to attack him in the shower.
Oliver asks Brick about Diaz at lunch. He tells Oliver he will only help him if he gets rid of Peter.
Oliver and Stanley formulate a plan together that gets them access to a computer where they find out Peter has a wife and a kid. Later on, Brick hands Oliver a screw so he can take care of Peter. Oliver protests at first, but Brick and his associates remind Oliver that he's playing by their rules.

Meanwhile, in Star City, The Longbow Hunters infiltrate one of ARGUS's offsite facilities. They steal an ultra high-density renewable battery.

Felicity begs Diggle to let her help with the operation, but Diggle says he can't break ARGUS protocols.

Diggle reprimands Felicity for blowing ARGUS's best possible lead. Diggle reminds Felicity that getting her old life back is impossible, and taking down Diaz won't change that. Felicity fires back by saying Diggle doesn't care about the last six years and should've worn the Green Arrow hood as Oliver asked.
Diggle tells Felicity he couldn't put the hood on and ruin his family like it ruined Oliver's. Felicity asks to help but John tells her she can only help if she does it the ARGUS way.
Diggle and ARGUS on a train looking for the battery, they try and fight off The Longbow Hunters but they are too powerful. Diggle sees Diaz at the mission.
