Yes, but the only thing we knew about her history before that was (a) she was from Beverly Hills (b) her grandmother gave her a locket, (c) she may have been a gymnast back in Beverly Hills (can never remember if that's stated or just me trying to explain away her skills). Compare that to Cyclone's introduction: she's going to college, she's a drama major, she's a fan of Stargirl, she was abducted as a kid and injected with nanites, Wicked is her favorite play, etc.
