Whose Plan of Escape is it Really?

Robin is dead. A year later, the Light has a Talon on their board. His name is Gray. He's full of tricks. But how does he know so much about the team and Batman? Who is he? What does Robin have to do with this? Is Gray really a bad guy? Beware... Who really owns the playing field? "You've got two options, Dick-" "That's cute. I'm whelmed."
