The next day, Thea is preparing for her 18th birthday and wants to get a car. Moira tells her that she won't be getting one and Oliver agrees. Thea leaves with Moira to meet with the party planner while Tommy arrives. They discuss how Moira has been acting erratically and turn on the news. The armored truck robbery is playing on the news.
Later, Oliver is exercising when Diggle comes in. He tells him about the armored robbery and plays back the video, and Diggle realizes that the robbers used military swarming techniques. Oliver explains that he was checking into people with that kind of experience and the trail led to Black Hawk Security and one of its employees, Ted Gaynor. Surprised, Diggle says that Ted was his commanding officer in Afghanistan. He's surprised when Oliver says that Ted is on Robert's list and explains that Ted offered him a job six months ago. Diggle points out that the book was written by the man who hired the Dark Archer, but Oliver insists that he can trust the book and tells Diggle that he's going to talk to Ted.
Oliver puts on the dead mercenary's clothing and mask, and then advances through the jungle to the camp. One mercenary comments on the food to Oliver and figures that he's new, and Oliver asks about Yao Fei. He says that he's there to transfer a prisoner and the other mercenary offers him a ride to the east camp where they took Yao Fei. Before they can go, Fyers limps over and gets in with them.
Tommy is overseeing the construction of the club when he gets a call from his father. Malcolm claims that he was trying to jolt Tommy into adulthood and figures that Tommy getting a job proves he was right. He suggests that they have dinner tonight, and asks Tommy to bring Laurel along. Before he hangs up, Malcolm apologizes for what he said and insists that he still wants the two of them to be close. Tommy says that he'll check with Laurel.
That night, Oliver goes to Black Hawk Security and takes out the security guards. He makes his way to Ted's office, knocks him to the floor, and warns him that things will go badly if he goes for his gun. Before Ted can respond, Diggle arrives, draws his gun, and tells Oliver to put the bow down. Before Diggle can do anything, Oliver shoots out the light and flees. Diggle checks with Ted, who assures him that he's as good as hired. When the bodyguard wonders why the Hood came after him, Ted asks what he thinks and Diggle says that he figures the Hood came after the wrong guy.
Back at the warehouse, Diggle complains that he could have shot Oliver. Oliver explains that his father told him that the names on the list are legitimate, after he left the island. When Diggle is still suspicious, Oliver says that he is sure enough of the list to lie to all of his friends and family. Diggle tells Oliver that Ted got him into Black Hawk and he plans to prove Ted is innocent. When Oliver wonders he'll do if Ted isn't innocent, Diggle says that Oliver owes him at least that much.
Fyers asks for a report from Oliver, unaware of who he really is. Oliver hesitantly stumbles through an answer and Fyers tests him, asking if he came in on the sub. Remembering what he's heard, Oliver says that he came on the plane and Fyers sits back, satisfied.
The next day, Moira and Thea go on a shopping trip and they talk about Robert. Malcolm calls Moira, who says that she's with her daughter, but she reluctantly agrees to meet with him. Thea complains that Moira said she'd be there but Moira says that it's business that can't wait.

Ted and Diggle meet at Carly's diner and they talk about bodyguarding jobs. Carly gets Ted a piece of cake and leaves, and Ted points out that Carly likes Diggle. When Diggle points out that Carly is his sister-in-law, Ted reminds him that his brother is dead. Ted's co-worker Paul Knox comes in and reminds him that they have a job. After shaking Diggle's hand, Paul waits outside and Ted explains that Black Hawk recruited Paul. Diggle is clearly suspicious of Paul based on past experience but Ted insists that everyone deserves a chance to prove that they've changed.
Oliver is at home accessing Black Hawk's computer system via a security fob he stole from Gaynor earlier when Thea comes in and says that they have to talk. She says that Moira is hooking up with Malcolm and says that it's happening all over again. When Oliver wonders what she's talking about, Thea explains that Moira and Robert were arguing a few months before the yacht went down. At the time she had a lot of lunch meetings with Malcolm, and Thea figures that she's doing the same thing again. Oliver doesn't believe it and Thea warns him that their mother isn't as perfect as Oliver thinks she is.
Oliver goes to Moira with Thea's suspicions and Moira finally admits that Robert cheated on her repeatedly.

Laurel thanks Malcolm for dinner and he asks Tommy for his signature on some papers. Tommy checks them and discovers that Malcolm is shutting down his mother's free clinic.

Digger goes to the motor pool and finds blood in one of the vans. It has a fake logo on it and Diggle confirms it was the van at the robbery. Paul comes in with a gun, aware that someone hacked their security system, and admits their boss figured Diggle wouldn't be cooperative. Ted comes in and explains that the whole thing is his mission. He's disgusted that he's reduced to bodyguarding rich spoiled brats and plans to convince Diggle to join him. Ted explains that they're down a man and Diggle is qualified to fill in. When Diggle refuses, Ted has his man Cavanaugh bring in Carly. Meanwhile, Oliver is listening in on the bug he put on Diggle and leaves the party.
Later that night, Diggle puts on a gas mask and fires a grenade launcher at an oncoming armored car. Ted and the others are in the van with Carly, watching.
