The final scene of “The Dark Knight” takes place in a hospital where Harvey Dent, who has become the villain Two-Face, has been taken after being injured in a fight with Batman. Batman visits him, and as Two-Face prepares to kill the people responsible for his scars, Batman intervenes and they engage in a struggle. During the fight, Two-Face is killed when he falls onto his own coin, which had been scarred on both sides and decided his fate.
Meanwhile, Commissioner Gordon is in the process of building a case against the corrupt police officers who helped the Joker. He plans to reveal the truth about Harvey Dent’s fall from grace to preserve his image as a hero in the city, but Batman intervenes and offers to take the blame for Dent’s crimes instead. Batman departs from the scene as Gordon watches, setting up the events for the next film in the series.
The final scene ends with Batman being branded as a fugitive by the police, with Gordon secretly knowing the truth about the hero’s actions but keeping silent in order to protect both Batman’s identity and Dent’s legacy. In this way, the ending of “The Dark Knight” highlights the moral ambiguity of the world of Gotham City and the lengths that Batman is willing to go to in order to protect the people he cares about.
