At some point, John lost his father and his brother to cancer.
About a month later, while sitting in his apartment one night, Diggle was paid a visit by the new vigilante Green Arrow, who was bleeding out and needed help. Diggle patched him up, and Oliver, believing Diggle was an honest man, asked him to join in his crusade against crime. Diggle accepted, and the two worked together for a time.
After some time, Diggle would put the vigilante life behind him, having had a falling out with Oliver due John impersonating him to kill Richard Dragon's father.
Years later, Diggle returned to Seattle to seek the help of crime boss William Tockman to take down Richard Dragon, who still believed that the Green Arrow had killed his father years ago. He also recruited the help of Naomi Singh and Henry Fyff. Tockman eventually turned on Diggle, stating that Dragon offered him a better deal. The villains let Fyff and Singh go, but kept Diggle as leverage against the Green Arrow.
While captured and tortured by Richard Dragon, Diggle admitted the truth that he was the one who killed Dragon's father and that his crusade against the Green Arrow was in vain.
Oliver returned to Seattle and learned of Diggle's captivity. At the last second, the Green Arrow saved Diggle from being murdered by Richard Dragon, and the two men teamed up to finally stop Dragon once and for all.
Later, Diggle was working as a soldier for hire when he received an anonymous message about Oliver Queen's death. After he learned that Queen was not actually dead, the two men got in a fight, with Diggle blaming Oliver for killing the woman he loved a year prior. However, this was resolved, and they joined forces yet again to take down the Ninth Circle.
During a climactic battle with the Dark Archer, as Green Arrow prepared to kill the villain, Diggle betrayed Oliver and saved Merlyn's life. Diggle claimed that Merlyn had saved his life years earlier and wanted to repay him, though Merlyn foreboded that Diggle would not be able to play both sides for very long and would eventually have to choose who he really aligned with.
