Complete story — includes the ending
Thompkins challenges Nygma to his game, the Riddle Factory, and wagers to abolish it if she wins. After she outsmarts Nygma, the two share a kiss. Jerome Valeska assembles the "Legion of Horribles" – Penguin, Mad Hatter, Scarecrow, Firefly, and Mr. Freeze – and sets out to find Wayne Enterprises associate Xander Wilde. Valeska shoots up a Wayne Enterprises building, but is unable to find Wilde and is forced to escape when the GCPD arrives. With help from Bruce, Gordon and Bullock locate Wilde, who reveals that he is Jerome's twin brother, Jeremiah, and also reveals that he has kidnapped Jerome. Mad Hatter and Scarecrow break out Jerome from Jeremiah's custody but are chased off by Gordon and Bullock. Cobblepot convinces Grundy to be hired muscle for the Legion of Horribles, just as Scarecrow concocts a laughing gas for Jerome to spread across the city.
