With Angel Lupo dead and presumed innocent, Batman no longer has a suspect for the murder of a young boy's parents. Only the Joker, locked in his cell, is able to give Batman the key to the mystery. He learns that Angel Lupo is killed by the Ventriloquist, his sister's lover, for the murder committed by Killer Croc under Margo Farr's authorization. All concerned are taken into custody, and Batman learns that the other murder of a boy's parents was committed by the boy himself. He also recalls his parents' last day, a day when he had an argument and told them he hated them.
