There was absolutely no change in Bruce's invesigation. He saw on the news about all the villains, and couldn't stop thinking about it. He had to do something to save his city.
He couldn't stop thinking about what Galavan kept calling him, The Son of Gotham. Maybe Galavan knew something about Bruce, that he didn't. Maybe he was meant to save his city. He thought about it alot, maybe if he had a way to fight all the villains in the city.
Bruce also thought about what was in the letter his dad left for him, You can't have both happiness and the truth. Bruce wanted the truth more than anything. Who had his parents killed, and why? Maybe someone wanted to keep them quiet. Maybe his parents stumbled upon something they weren't suppose to. All he wanted was answers.
