Actually, Grayson began in a very dark, or at least adult, direction, with the first three issues featuring manipulation, cannibal scientists, tragedy, sexual games, and much else. Then, in the fourth issue, you could almost hear the cries of “pull up, pull up, Mayday, Mayday!” We have a sharp turn toward the skull girls as carnival figures, Helena as a sympathetic friend, Tiger as an honorable warrior, the cannibal doctor as a recurring joke (leading to eventually writing her out in Robin War with a twist that made no sense at all) and chasing each other over the rooftops. I remember King saying there was talk of ending Grayson with issue five or six. I wonder if these changes relate to that?
