Complete story — includes the ending
In the aftermath of the Tetch virus incident, Penguin has regained control of Gotham 's underworld and begun issuing "Licenses of Misconduct", allowing criminals to commit "legal crimes," though not approved by Gordon and Bruce. Selina and a reluctant Tabitha agree to a license. A group of unlicensed criminals led by Merton and Grady Harris decide to defeat Penguin, releasing Jonathan Crane from Arkham to help them produce his father's fear toxin. Knowing that Gordon cannot help, Bruce decides to fight the licenses himself. The night Penguin opens the Iceberg Lounge, the Harrises are captured before they can attack the party but, when Penguin decides to execute them, Ivy turns on him and cuts the power. Merton uses the fear toxin on Penguin before Gordon shows up and takes him into custody. The toxin makes Penguin see an escaped Nygma. Bruce steals the list of licensed criminals, but is then found on the scene of a robbery by the GCPD, bank robbers. Grady, who escaped from the party, returns to Crane's house, but discovers Jonathan has adopted a new persona, calling himself "Scarecrow" and spraying Grady with fear gas.
