Joker 2: Folie a Deaux was released in theaters worldwide to provide a continuation of Arthur Fleck’s story. However, the film leaves viewers with many unanswered questions at the end. One question that has arisen after the ending of Joker 2 is who carried out the attack and planned the explosion in the courtroom during Arthur Fleck’s trial. Although, the film doesn’t seem to give much explanation about the explosion in the courtroom.

Here are a few possibilities that could reveal the identity of the mysterious attacker.

In Joker 2: Folie a Deaux, fans will see Arthur Fleck go on trial for the cold-blooded murders he committed in the first film. The film will also shed some light on the identity of Joker and whether he was a different character altogether.

In the courtroom, as his lawyers try to prove that it was not Fleck but his alternate personality, the Joker, who committed the murders, Fleck feels the guilt building upon him. So, in the defining moments of the trial, Arthur Fleck abandons his Joker persona and confesses that he is solely responsible for the murders. Shortly after Fleck's confession, Lee Quinzel, aka Lady Gaga's Harley Quinn, abandons him and leaves the courtroom as a car bomb explodes.
