Batman Interrogates the Joker

At Gordon's Major Crimes Unit building, James Gordon is promoted to Commissioner by the Mayor. The Joker shares a cell with a large man who complains about his insides hurting. Commissioner Gordon, after reuniting with his family, gets a call explaining that Harvey Dent never made it home. He returns to the prison to interrogate the Joker. During the interrogation, Batman appears and starts beating on the Joker, trying to find out where Harvey is. The Joker gets under Batman's skin telling him that they are both freaks and that when the people of Gotham no longer view Batman as a necessity, they will turn on him. Batman becomes enraged and puts a chair under the door and beats the Joker savagely.
