11. Trust but Verify

Complete story — includes the ending

After an armored truck is robbed, Oliver believes that one of the thieves is Marine Ted Gaynor, a target on his list. Diggle dismisses Oliver's assumption, as Gaynor was Diggle's commanding officer during his time in Afghanistan. Oliver finds Gaynor and steals encrypted data, though Diggle prevents Oliver from getting any information directly from Gaynor. The data is revealed to be plans for robbing armored trucks, which Oliver uses to track the thieves. Diggle learns that Gaynor masterminded the robberies and is forced to join Gaynor's team, but backs out of helping them. Oliver arrives in time and kills Gaynor. Meanwhile, Thea tells Oliver she believes that Moira and Malcolm have been involved since before Robert's death. Oliver asks Moira, who states Robert was unfaithful. Tommy refuses to sign off on Malcolm's wish to sell the clinic established by his mother, who died when he was eight, blaming Malcolm for leaving him for years thereafter. Thea is arrested by the police after crashing as a result of drug use. Flashbacks show Oliver being captured by the mercenaries, as Yao was apparently working for them.
