I must say, while there's no particular reason for Black Canary to fill the role, there are worse origins for a female vigilante than finally snapping after a long period of being groped and slobbered over by every blue-collar redneck lowlife in Gotham - which means, basically, every man in Gotham, pretty much. Miller, you're slipping; that almost made sense. And why is the blond guy called 'Dorothy'? What kind of nickname is that, unless, of course, Miller's trying to imply that the two of them are gay, and if they are, then why are they drooling over the hot new barmaid?
