storyline [1] Aaron Langstrom, mutated son of Dr. Kirk (Man-Bat) and Francine, was kidnapped. His mother took the serum and found her child. Batman warned her to not cross the line or he'd take her down.
[2] Batman and Oracle were able to get a local access type NML broadcast out to the entire country showing what really was happening there.
[3] While fighting Killer Croc, Batman's mask came undone. An old associate now living on the streets, Dr. Kryder, saw him and realized he was Bruce Wayne. He tried to sell the information to Two-Face (he'd once tried to cure Dent), but the coin came up bad-heads and Two-Face killed him.
