"Hush, Chapter 9 of 12: The Assassins"
*Batman has picked up a hint that Ra's al Ghul may be behind the recent events in Gotham and Metropolis, so he kidnaps Talia and heads out to Arabia to confront his old archenemy. Meanwhile, Harvey Dent approaches James Gordon, telling him that Batman needs their help as they've all been played for fools. When he confronts al Ghul, Batman learns that his opponent has also been used by his mysterious adversary - one of the Lazarus Pits has recently been used. Back in Gotham, Catwoman fights Lady Shiva to protect Talia; she loses the fight but is saved from death by Talia. Talia warns Batman that his enemy will use his love for Catwoman against him, but Batman believes this danger is worth it. *Source: DCUGuide.com
