Batman (1940) 619-B

"Hush, Chapter 12 of 12: The End"

*Batman battles "Hush", the man in a trenchcoat with a badaged face who has been behind his recent troubles. In time, Hush reveals who he really is - Tommy Elliot, Bruce's childhood friend, who harbored a great hatred for Bruce because Thomas Wayne saved the life of Tommy's mother when he wanted her to die. Help arrives in the form of James Gordon and Harvey Dent, the latter healed by Tommy Elliot but breaking his agreement with him. Elliot is defeated and plunges into Gotham harbor, most likely to his death.

Two weeks later, Catwoman and Huntress compare notes, while Batman and Superman do the same, Batman showing Superman what is was that had caused him to think of Tommy Elliot for his surgery - subliminal messages implanted in the computer by Harold - and Superman removing some sort of homing device from the base of Batman's skull. Batman also confronts the Riddler, who was working with Dr Elliot, and knows the secret of Batman's secret identity. Batman shows him how he can never reveal this to anyone, because a riddle everyone knows the answer to is essentially worthless. And his relationship with Catwoman fizzles out, due to a lack of trust on Batman's part, though Catwoman would be more than happy for things to continue. *Source: DCUGuide.com
