Quentin Larry Lance is a police detective, formerly a sergeant and officer, of the Starling City Police Department. He was partners with the late Lucas Hilton before being demoted, as well a good friend. He was finally reinstated as detective when Slade Wilson launched an assault on Starling City. Quentin is the ex-husband of Dinah Lance, and the father of Laurel Lance, and Sara Lance. Quentin had originally sworn to take down The Hood by any means necessary, even using his daughter once as bait. This changed after The Hood told him about Malcolm Merlyn's plan to level The Glades and everyone in it. He finally came to see The Arrow as a good person, not as a menace to the city, and frequently helped the vigilante, along with his daughter, The Canary, on their missions.
