The Joker is trying to prolong his inevitable fate by seeing a string of doctors. The latest doctor explains that Joker has been poisoned by a mutated form of the Titan formula, and presents him with a weaponized form of the Titan toxin. Hours following Batman's discovery of Hugo Strange's identity Batman gathers all available, and rather incriminating, information on him. However, Strange is one step ahead and has Sharp announce his involvement in the Arkham City Project in order to prep an alibi against Batman/Bruce Wayne's accusations. He further boosts his popularity by secretly releasing Zsasz and having his forces recapture him, proving that The Gotham Police Force are weak and obsolete and giving TYGER a defining reputation.
