Uh where so you get that from? She was falling all over herself in the beginning of the movie, she portrayed herself as a klutzy waitress with glasses and little self-confidence. She didn't have a mental breakdown,
she DIED. The cats
brought her back to life, heck, they even touched on this in the god-awful Catwoman movie. But lets say I'm wrong and you're correct, that she had some sort of physical prowess you say... enough to fight Batman?
Are you kidding me? No secretary can beat up Batman, not even that broad from the Drew Carey Show, Mimi...

no, have to disagree with ya on this one, it's one of those things that made Returns more fantasy to me....
