But the Joker has a plan as he forces Batman to make a decision, stop him or rescue innocent people the Joker has dangling from an adjacent building. There are too many people as Batman can not save them all but he manages to take the Joker down. Lorna is going to recover but Bruce breaks off their relationship in an effort to save her from any more attacks, though she does not know this is the real reason for the break up.
