Quote: the G-man said: The current retcon is going to have to be retconned soon.
If we accept Dinah is about thirty, then she was born in 1977 (or thereabouts).
At the same time, if we accept her mother was the Golden Age Black Canary, the we have to assume that her mother was in her late twenties or thirties when she was operating during the G(olden) A(ge).
This means that, when Dinah was born, her mother would have been in her late fifties ...or early sixties.
At some point, we lose the suspension of disbelief that the GA BC could be the mother of the current BC, if we haven't already lost it.
this is why I hate the sliding scale timelines that DC and Marvel use.
