Meanwhile Gordon discovers that there are 3 traces of DNA on the Joker card, from Commissioner Loeb, Harvey Dent, and Judge Surrillo, the Judge that is trying all of the mob members and found the card among the paperwork. Gordon takes this as a threat on their lives, and begins preparations to protect them. In the case of the Judge and Commissioner Loeb, however, this fails. The Judge's car blows up when the police arrive to take her into protective custody and Commissioner Loeb dies of severe poisoning from his liquor bottle before Gordon can stop him from drinking.Dent takes Rachel aside to ask her to marry him, but she is torn and cannot give him an answer. Bruce subdues Dent and locks him in a closet while Rachel watches in shock. Bruce tells Rachel that they (the Joker and his goons) have come for Harvey and to stay hidden from sight.

As Harvey Dent's fund-raiser at Wayne's penthouse gets underway, Rachel and a nervous Dent arrive and mingle. Wayne arrives with three models via helicopter and seeks out Harvey, whom he applauds and throws his full support behind claiming, "I believe in Harvey Dent." Minutes later, Rachel meets with Bruce on the balcony upset that Bruce is making fun at Dent but Bruce tells her that he truly believes in Harvey and that he could be the White Knight that will allow him to hang up his mantle as Batman so they can be together. Dent joins them to thank Bruce and retrieve Rachel.

Dent, Gordon, and Commissioner Loeb meet with the mayor to tell him that Dent's rash indictment of the mob members will give the mayor clean streets for 18 months. The mayor informs Dent that his brash actions will bring down the full might of Gotham's underworld and corrupt citizens solely upon him. When the mayor asks if Dent is ready to be the city's target the dead body of a Batman wanna-be hanging by a noose slams against the mayor's window dressed up in a Batman suit, with makeup on his face like the Joker's - complete with the sides of the mouth sliced into a grin - and with a Joker card pinned to him reading 'Will the real Batman please stand up?'. Bruce and Alfred watch on as a video tape is played on the news of the Joker tormenting the wanna-be before killing him. He then promises that until Batman takes off his mask and shows everyone who he really is, people will die every day.

Gordon appears at Maroni's restaurant as the police rush in to arrest all of the mob members in attendance. As all of the mob members that Lau informed the police are rounded up for arraignment, Judge Janet Surrillo finds a Joker card in the middle of the stack of conviction papers. Dent gives a televised impromptu interview denying Batman's involvement while expressing gratitude for the police work in bringing the mob members to justice.

Back in Gotham, Lau is interrogated by Rachel with Dent and Gordon looking on. Rachel presses him to give them the money Lau has taken, but Lau will not give in. After she threatens to have him moved to the County lock-up, Lau tells her that he can give them the names of the mobsters and their pooled investments. Dent then realizes that they will have the leverage they need in a RICO case of conspiracy to link all of the mob members together. Gordon decides to keep Lau in his holding cell at the Major Case Unit building and Lau agrees to cooperate with the police, and give the names of the mob members.

Meanwhile, Fox arrives in Hong Kong to meet with Lau. He checks in his mobile phone at the front desk at Lau's building, as there are no cell phones allowed on the premises. Fox meets with Lau, and informs him of Wayne Enterprises' plans to cancel negotiations with his company. However, he secretly keeps one cell phone in his pocket, which has been adapted to produce a sonar map of the surrounding area. Upon leaving the building, he does not pick up the phone he dropped off, and he produces the map of the building to Bruce Wayne. That night, the phone that Fox left at the front desk emits a high frequency that shuts down all power in the building. Batman crashes in through a window in Lau's office, and after disabling some guards, grabs Lau and escapes by sending a balloon attached to a cable to a plane he has chartered flying over Lau's building.

Gambol is playing pool with some of his associates until one of them informs him that a group of hoodlums havd killed the Joker, and has the body. The body is brought in covered in a bag, and as Gambol is about to pay, the Joker rises up and holds a knife to his face while his men hold guns to his associates' heads. The Joker tells a story about how he got his scars from his father, and then kills Gambol. He offers the three surviving associates an opportunity to join his team, but he has only one opening. He leave the three with the halves of a broken, sharp pool stick and no choice but to fight each other for their lives.
