While Lance has been dealing with the junkie, Queen has finished unpacking, and decorating their new home. Feeling nostalgic, Queen reminisces about his past.
As a boy, Queen idolized Howard Hill, an archer who worked on the film, Robin Hood. As an adult, Queen, by chance, met Hill, on a yacht trip, and spent an afternoon talking about archery with his idol. During the cruise, Queen drunkenly fell overboard, washing up on the shore of a remote island. Queen forced himself to learn archery to survive. After honing his survival skills, for years on the island, Queen encountered two men, who had arrived to check on their marijuana crop. Queen brought them to justice, and finally escaped the island. While under the influence of their drugs, the dealers referred to Queen as "The Green Arrow".
Queen adopted the name, becoming a masked vigilante, upon his return to Star City. Queen relished the roll of the Green Arrow, though it ultimately cost him his fortune, and very nearly his ward, Roy Harper, who had developed an addiction to heroin. Coming out of his reverie, Queen realizes that Lance has abandoned him. Lance appears in her Black Canary costume, and entices Queen to bed. A police officer, undercover as a prostitute, is murdered by the Seattle Slasher.In the aftermath of their coupling, Queen asks Lance to marry him. Lance turns down his proposal.
