More interestingly is that Bruce's tryst with Miranda/Talia is the first time in the Nolan films Bruce gets any "action," as it were. Apart from some smooching at the end of Batman Begins
, we never see him romancing anyone (which led to my theory that the whole reason he's such a good "angry" Batman is because he just really
needs to get laid. Sure enough, once he does, he gets the shit kicked out of him by Bane.
