The robbers kill the guards, then unload the cargo and flee.

Oliver notices something familiar about it.
At the "Arrow Cave", Oliver is doing push-ups when John Diggle arrives.

Later that night, Oliver shows up at Black Hawk Protection where he knocks out a few guards and heads directly for Ted Gaynor. First he knocks him down and tells them that they need to talk when Diggle arrives with a gun pointed at Oliver. Oliver shoots a computer causing sparks to blind Ted and John as he grabs a flash drive from the desk and bolts out of the building. Impressed with Diggle's timing, Gaynor offers him a job. John comments that the vigilante normally only targets the rich, so he must have made a mistake.
When Diggle returns to the lair later, Oliver and him get into an argument over the situation. Oliver tells him that he knows that all the names are criminals because of what his father told him and what he learnt after he left the island. John still tells him he doesn't believe it and that he has accepted the job at Black Hawk to prove his innocence. Oliver asks him what he will do if he finds that he isn't, but Diggle avoid the question.

She explains that just before Robert disappeared, she was spending a lot of time with then too. Oliver tries to convince her that it isn't happening, but she tells him that Moira isn't the good person he believes she is.
Later, Oliver confronts Moira over Thea's accusations. Moira tells Oliver that Malcolm helped her when she found out that Robert was cheating on her, but she never told them since she didn't want to ruin their memory of their father, and asks Oliver not to tell Thea. He asks her why Thea would suspect such a thing, so Moira tells him that they meet frequently since she needs help running the company.

Ted is giving John a tour around their vehicles when the conversation returns to Knox again. Ted tells him that jobs are hard for people like them and that he Knox would probably be robbing liquor stores if he didn't hire him.
Felicity has finished decrypting the drive and tells Oliver that the information is only about security routes of the cities armoured car companies.

Oliver asks Diggle about his ventures that night at the lair. John tells him that he revealed a watered down version of the truth and they know he was coerced into it, then admits he was wrong. Oliver tells him that he is wrong about many things too since he doesn't trust his friends after the island and tells Diggle that he he appreciates him as a partner.
