Re: How Long Was Bruce Wayne Actually Batman in this Trilogy?
It essentially disappeared throughout the events of TDK, though. Dent did get most of the criminals off the streets for a year and a half and the top guys died one by one in the film as well. Enough time to have created the Dent Act, put it into action and send any other mobsters to prison. And while I agree that the LoS could have definitely ended in BB, there is a daughter that Ra's had in the comics which could have made her way into Nolan's universe and she did.
