...at batman is Bruce Wayne. The only other person that batman should have know is Jason todd. He is the only person that can fill in the blank to where all these Easter come from. Plus we can safely assume that robin was beat to death by joker but did not say that he actually die but some what survive from jokers retaliation and gave his name as the red hood. That's my theory. Hopefully I didn't miss anything but if I did please by all mean fill me in.
