plans to sell it to terrorists, and tracks him to war-torn Lebanon. Walking through his old neighborhood, Jason meets a friend of his late parents, who gives him his father's old documents. Jason discovers that his mother's name on his birth certificate is blotted out, and that her first initial is "S", not "C" as in Catherine Todd, the woman he knew as his mother. Jason concludes that Catherine was his stepmother and decides to search for his biological mother. He uses the Batcomputer to track three possible individuals to the Middle East and Africa. Jason travels to Lebanon, where he and Batman reunite. The two foil an attempt by terrorists to destroy Tel Aviv using the nuclear missile purchased from the Joker. Batman agrees to help Jason find his mother, and Jason interrogates his first suspect, Mossad agent Sharmin Rosen. His next suspect, Batman's old acquaintance Lady Shiva, says she is not Jason's mother after she is administered a truth serum by the duo. Batman and Jason travel to Ethiopia and confirm that Jason's mother is Sheila Haywood, an aid worker; Jason has an emotional reunion with her. However, the Joker discovers that Haywood had performed illegal surgeries on teenagers in Gotham and has been blacklisted as a medical practitioner. The Joker uses this information to blackmail her into giving him the medical supplies her agency has stockpiled in a warehouse. He sells them on the black market and stocks the warehouse with Joker venom, which will kill thousands of people. Haywood has also been embezzling from the aid agency and, as part of a cover-up, hands Jason, in his Robin costume, over to the Joker. The Joker beats Jason with a crowbar and restrains him and Haywood in the warehouse with a time bomb. Jason throws himself on the bomb to shield Haywood as the warehouse explodes. Batman arrives too late to save them, and Jason and Haywood die from their injuries. Traumatized, Batman takes Jason and Haywood's remains to Gotham and holds a burial with Alfred Pennyworth, Commissioner James Gordon, and Barbara Gordon. Batman blames himself for Jason's death and resolves to carry on alone, rejecting Pennyworth's suggestion to involve Dick Grayson, the first Robin. The Joker meets with Ayatollah Khomeini, who offers him a role in the Iranian government. The Joker leaves a warehouse containing the corpses of his henchmen and the address of the UN
