Complete story — includes the ending
Selina is hospitalized with severe spinal damage. Ra's al Ghul kidnaps Bruce, breaks Jeremiah out of custody, and steals his bombs back from the GCPD. Nygma tries to kill Gordon and free Lee from her old self, but Lee falsely convinces Nygma that she no longer loves Gordon. Cobblepot, Alfred, and the Sirens briefly ally against Jeremiah and the League of Shadows. Barbara kills Ra's with his knife (gripping it in Bruce's hands), while Jeremiah's bombs kill the mayor and destroy every bridge out of Gotham, reducing the city to lawlessness. Cobblepot hires Hugo Strange, who successfully turns Grundy back into Butch; however, Cobblepot then kills Butch in front of Tabitha as retribution for his mother. Lee decides to help the civilians and breaks up with Nygma, but the confrontation ends with the two stabbing each other; Cobblepot finds their bodies and orders Strange to "fix" them. With Gotham largely evacuated and overrun by criminals, Bruce accepts his destiny as the city's protector and begins hunting Jeremiah. Gordon, supported by Bullock, Fox, and a dozen other cops, also stays to fight for the city and operates a searchlight atop GCPD Headquarters as a symbol against the darkness.
