1 thing about Nightwing the last few years is at least he has been consistant.
He has consistantly been bad at keeping his identity secret, bad at fighting, and bad at interpersonal skills.
I just read NW 120, and...while as Dick Grayson modeling as NW (what a concept, never been used before! lol) he gets into a fight in front of a crowd using his abilities?
And later on, YET ANOTHER person finds out his secret identity.
Not to mention he just drops Jason Todd's name to Clancy, so she should probably go on the list of people who probably know his identity.
