Quick recap
With Bruce Wayne busy with Batman Incorporated, Dick Grayson patrols Gotham as Batman. A case about a boy turned into a monster leads him to the Mirror House, a black-market auction of supervillain gear, where he's nearly poisoned. Meanwhile, James Gordon Jr., the commissioner's son, returns to town claiming he wants to make amends. Gordon and his daughter Barbara suspect him, and rightly so: James made a version of a drug that turns people into psychopaths, and he mutilated his mother. The jailed Joker helps bring out the truth. In the end, James kidnaps Barbara and cuts an artery, but Dick saves her thanks to a tracker. Gordon arrests his own son and talks with Dick about what they can still hope for.
