>In court the following day, in his closing argument, a devastated Arthur renounces the Joker persona, taking full responsibility for his actions. Furious, Lee storms out, and the jury finds Arthur guilty of first-degree murder. As the judge reads the verdict, a car bomb explodes outside the courthouse, killing and injuring numerous attendees. In the chaos, two followers help Arthur escape, but he soon flees from them.
>Arthur wanders through Gotham and encounters Lee outside his old apartment, but she rejects him for renouncing his Joker persona and admits that her pregnancy was another lie before she leaves. The police apprehend Arthur and return him to Arkham. The next day, a patient approaches Arthur and begins to tell him a joke before repeatedly stabbing Arthur in the stomach. As Arthur bleeds to death, the young patient carves a smile into his own face while laughing.
Yeah, that's as blatant a Fuck You to fans of the first movie as you get.
