|Outbreak of Arkham Asylum|
|Location:||The Narrows, Gotham City|
|Result:||The following occur:|
At a party held at his mansion, Bruce is confronted by a group of ninjas from the League of Shawdows and his old mentor Ducard, who then reveals himself to be the real Ra's al Ghul, the former who died being a decoy. Ra's, who had been conspiring with Crane the entire time, plans to destroy Gotham by distributing the toxin (which was extracted from his blue flowers) undetected via Gotham's water supply, and then vaporize it with a microwave emitter stolen from Wayne Enterprises. Bruce, tricking his guests into leaving, fights briefly with Ra's while the League of Shadows set fire to Wayne Manor. Bruce escapes the inferno with Alfred's help just as the manor is destroyed.
The League, disguised as SWAT members quickly dispatch the rest of the staff and set a bomb at near the wall leading into The Narrows. Batman arrives at the "Narrows" section of Gotham to aid the police, who are engaged in battle with psychotic criminals set free from Arkham Asylum by the League. After saving Rachel, and intimating his identity to her, he leaves Gordon in control of the Batmobile to stop the elevated train that is being used to transport the vaporizer to the city's central water hub. Batman battles Ra's, then escapes just as Gordon topples the elevated line using the Batmobile's missiles, leaving Ra's to crash with the train to the ground.
Following the battle, Batman becomes a public hero. Bruce gains control of Wayne Enterprises and installs Fox as CEO, firing Earle. However, he is unable to hold onto Rachel, who cannot reconcile her love for Bruce Wayne with his dual life as Batman. Gordon, newly promoted to lieutenant, unveils a Bat-Signal for Batman and mentions a new criminal that, like Batman, has "a taste for the theatrical", leaving a Joker playing card at his crime scenes. Batman promises to investigate and takes off into the night.
