- —Edward Nygma to Oswald Cobblepot[src]
A military task force, led by Eduardo Dorrance is called in to provide relief to Gotham. Meanwhile, Nygma looks for answers from Penguin, who leads him back to Hugo Strange. Then, Bruce is concerned about Selina's recent behavior.
Eduardo Dorrance, a soldier who once worked with Gordon, arrives in Gotham with the military. Nygma goes on the run after Gordon discovers that he blew up Haven, leading to a citywide manhunt. After regaining his memory of the same night the bridges blew, Nygma confronts Cobblepot and learns that Hugo Strange revived him. Strange reveals he implanted a chip in Nygma's brain to mind-control him; Gordon arrives and discovers Nygma's innocence. However, Dorrance reveals that he is the one controlling Nygma and activates the chip, forcing the latter to pursue Gordon. Simultaneously, Selina is declared a hero by the underworld for killing Jeremiah and turns away from Bruce, but Jeremiah awakens elsewhere, having fully recovered from his injuries.
