Quick recap
Batman benches Jason Todd as Robin after the boy disobeys orders. Jason learns the woman who raised him wasn't his birth mother and heads to the Middle East to find her. Batman goes too, chasing the Joker, who has escaped Arkham with a nuclear weapon, and the two end up together. The search leads to Ethiopia, where Jason finds his mother, Sheila, an aid doctor. But the Joker is blackmailing her, and Jason falls into the villain's hands. The Joker beats Jason with a crowbar and leaves them both locked in with a bomb. Jason shields his mother, and both die. Later, the Joker becomes Iran's ambassador to the UN; Batman and Superman foil his attack, and the villain vanishes into the sea.
