I went back and reread from the start of the new 52 in each of the Batman lines the last few weeks, and It seems like they have dropped a few women in and then they've just vanished. In the Dark Knight there was Jaina Hudson (white rabbit), then she was gone. Followed by a Ukranian Pianist named Nataysha, in Detective theres Charlotte Rivers. I'm sure I'm forgetting someone, but I'm wondering were any of these people present pre 52? I am not current on pre 52 for a few years so maybe they existed before and I just don't know it.
