An outlaw whom Mattie, LaBoeuf, and Rooster find in a dugout in Indian Territory. Along with his companion Moon, Quincy is waiting for Lucky Ned Pepper and his gang, planning to give them a group of stolen horses to make their getaway easier in the aftermath of their mail-train heist. To get Quincy and Moon to come out of the hut, Rooster tells LaBoeuf to put a jacket over the chimney, which forces them to open the door, at which point Rooster shoots into the smoke, ultimately hitting Moon in the leg. Eventually, Quincy tells them they won’t fight back, and the trio enters the dugout, where they question the men about what they’re doing. When Moon starts to give them information about Ned Pepper, though, Quincy chops of his friend’s fingers to silence him. Seeing this, LaBoeuf shoots Quincy in the neck.
