[Going by the vague information she knew about Wonder Woman and the Amazonians.]

No, sorry. With the exception of Speedy or Red Arrow or whatever he was going by at the time, the only other superheroes my age I knew were the ones on the Team.

Even then, Robin's the only one who's actually my age. [Give or take half a year] The rest were all older.
