This is a question on older comics: when, in post-COIE continuity, did Dinah learn Batman's identity? Did she learn it - I assumed so, but I haven't read much post-90s Batman for himself (only read other Batfam and saw him when there).
I know that she did not know Batman’s identity (or rather didn’t know Nightwing’s) in Nightwing #58 (August 2001). I just don’t know when she did learn or if she retconned into not knowing (having previously known in post-crisis). I figure more likely she didn't know before that, since post-COIE Batman (and even later bronze age) was more secretive about his identity than he was in earlier versions.
Anyway, I just like lists and am trying to figure out when each hero found out other's identities in the different eras.
