Jack Gruber and Aaron Helzinger escape from Arkham Asylum and are on a rampage through Gotham. James Gordon promises the Commissioner he will arrest Gruber within 24 hours and he is reinstated as a detective for that time. Edward Nygma tells Gordon and Bullock that Jack Gruber is an alias of Jack Buchinsky, a former bank robber for the mafia who was betrayed by Salvatore Maroni. Fish Mooney makes her move against Falcone and "abducts" Liza. Gordon and Bullock put Maroni under protective custody to use as bait to attract Buchinsky to the police station. Falcone discovers that Mooney is behind Liza's abduction, and is offered a deal. Falcone is to sign his crime family over to Mooney's gang in exchange for the opportunity for him and Liza to leave for Italy. Buchinsky attacks the police station in search of Maroni. Gordon, protected by rubber boots provided by Nygma, is immune to the initial attack and thwarts Buchinsky's bomb. Before Falcone goes through with the deal, Cobblepot informs him that Liza was always working for Mooney. Falcone confronts Mooney and Liza at the former's club, and strangles Liza to death. Victor Zsaz and several mercenaries working for Falcone then take both Mooney and Butch Gilzean prisoner, while the Don gives Cobblepot a chance to mock his former boss, as he has inherited her nightclub as well as what is left of her gang. For living up to his end of the deal, Gordon is reinstated as a detective.
