Spoiler :
when Harry finally reveals his plan to overtake Millenion to Brandon on a glass elevator, who knew all along what Harry was doing behind the scenes. Brandon draws his gun to stop Harry and protect Maria, Big Daddy, and uphold the syndicate's iron law, but cannot bring himself to kill his best friend despite having lived as an assassin up to that point in order to help him. Brandon drops his gun, and Harry draws his own, puts several bullets into Brandon's chest, and then presses the gun up to his left eye, breaking Brandon's glasses and pushing him against the already cracked glass elevator wall, shouting "BRAAAANDOOOOOON" and firing the final bullet straight through his head, knocking him out into the open sky and plummeting to his death.
