Gordon: 'There's been a series of jewel robberies....'
Batman: 'Stop right there, Jim. The Joker has killed the Mayor, Commisioner Loeb, Rachel Dawes, blown up a hospital and two barges, and while we now have him locked up, the DA has been scarred and gone nuts, killing all the gangsters around, and is still missing. And with all that going on, you want me to track down a jewel thief? Shove it up your a$$, Jim.'
Gordon:'... I was only asking.'
Batman: 'And you never will again.'
Seriously, though, I feel that Two-Face is obviously going to be the bad guy in part III, so it doesn't have to be a subtle allusion. IMO.
