Warning: The following contains SPOILERS for Gotham Knights season 1, episode 5, "More Money, More Problems."An aspect of Harvey Dent's character that was ignored in the movies The Dark Knight and Batman Forever plays a major role in the origin story of Two-Face in the Gotham Knights show. Played by Supernatural's Misha Collins, the Gotham Knights version of Harvey Dent has played a minor but pivotal role in the series to date, acting as the lead investigator into the murder of Bruce Wayne. This was in keeping with the character's original heroic nature, with no hints that he might become the villain that he is in the mainstream DC Universe.
