Bruce Wayne disappears... imagine that someone new puts on the make-up and becomes the new Joker, and the Joker masks himself and becomes a crime-fighting detective, Oberon Sexton "The Gravedigger," to counteract his replacement. As he was the Yin to Batman's Yang, he is now the Batman to the new Joker. I think that is what's happening in Batman and Robin right now, but it's so mysterious with the current Batman (**** Grayson) uncovering information about the Wayne heritage and secret places in Wayne Manor that only Bruce would have known about, Alfred discovering more and more of the Wayne heritage, and Red Robin (Timothy Drake) searching the globe for more signs of Bruce while he also gets in a tangled tussle with Ras al Ghul's secret society of assassins. And Damian Wayne is being controlled by his mother, Talia al Ghul, and the assassin Deathstroke in an attempt to have the boy kill **** so that nothing stands in the way of his mother's plan to make him the Alexander the Great-esque conquerer she wants him to be. And the poor kid just wants to be Robin and wants his dead father's approval. But his father isn't dead, and is traveling through time having to relive all of history and its agonies to get back to his current state... but when they discover him, he might be completely insane... he might even not think or act like Bruce Wayne anymore. He might take on the mantle of someone else, and Damian currently thinks that Oberon Sexton is Bruce Wayne, while the reader thinks it is the Joker.
You should get into Batman comics, is what I'm trying to say. It's awesome.
