Did you see BA's statement on adding it? ""The thing about this is that it's controversial, so we added more controversy," explained Azzarello. "I think she is stronger than the men in her life in this story. She controls the men in her life in this story. She comes off as a stronger character at the end of that arc."" Absolute hogwash, KJ isn't even a Batgirl story! She's collateral damage in order to break Gordon, he doesn't shoot her because he knows she's Batgirl or anything.
