At the same time, Batman, wearing a different emblem on his chest, apparently resurfaces and is quickly noticed by Robin and Katherine Kane. Both of them intercept Batman and quickly deduce that it is Grayson wearing an old version of the Batsuit. They begin their own investigations into the Heretic, unconvinced that Bruce is truly dead. Soon the Heretic and his henchmen attack Wayne Enterprises, forcing Lucius Fox to open the way into the vault by threatening his son Luke Fox, a soldier recently returned from Afghanistan. Though Grayson and Damian quickly arrive, they are unable to prevent the Heretic from escaping with Wayne technology, and Lucius Fox is non-fatally stabbed. Before they leave, Heretic kills Electrocutioner when he is about to kill Robin.
