Warning: The following contains SPOILERS for Gotham Knights season 1, episode 11, "Daddy Issues."A new origin story in Gotham Knights has tied Harvey Dent's trademark coin and the Joker's Daughter together, reconciling the conflicting origins of Two-Face from the comics. Despite being one of Batman's most popular enemies, Two-Face has been portrayed in radically different ways by different writers. In some stories, he is obsessed with duality. In others, Two-Face is captivated by luck and administering his twisted idea of justice, for good or ill, with a coin flip. However, Gotham Knights has found a way to make all these interpretations fit a single character.
