The end of the book would have you believe as much!
Goatboy gets into a confrontation with Batman while trying to snipe Robin from across town, and things seem to go slightly upside down. He recounts the story to Leviathan, coming to them about a task that so many other assassins sought to accomplish, but one that he did.
His fight with Batman ended with a shot to Batman’s bullet proof helmet. This left him distracted long enough for Goatboy to get the kill he wanted.
Robin is dead?
Is it just me or does this story not fully add up? Like, where’s the battle damage to Batman’s mask?
