Making his way to Wayne Manor, Man-Bat strikes and Bruce goes into action as Batman. The struggle is taken back to the Batcave and Jason follows them, hoping to help in any way. When Man-Bat gets the upper hand on the fight, Jason attacks the monster, saying something about his "father". Man-Bat realizes that there is a connection between Batman and the kid, and he kidnaps the boy to make Batman suffer in the same way as he had suffered after the loss of his daughter.
