By the way, one thing the New52 definitely got right when it came to changing Batgirl was once again making Barbara Jim Gordon's biological daughter from his own marriage.
(In the post-CoIE revisions, they originally had Barbara as Jim's niece who was adopted by Jim and his wife when Jim's brother and sister-in-law were killed.
I believe there was a later possibility of Jim actually being Barbara's biological father, but as a result of an affair Jim had with his sister-in-law?)
