Nice to finally see some acknowledgement that yes, the people that the Dark Knight has fought repeatedly for the past ten years or so might NOTICE when the post is filled by someone else. (True, they didn't notice when Dick donned the cape the first time during the 'Prodigal' storyline, but that was only for about a month, and Dick wasn't doing the 'smile for the camera' thing, either.) It'll be interesting to see how the Joker reacts when he finally goes up against the new Bats.
