How unfortunate, that kick would have knocked out the majority of people. But the costumed ones were never as easy, she knew that, but she could always hope. Batgirl watched her, she was hurt, and she was confused. Either the blow had messed with her memory, or she didn't know who Batgirl was. In her case, Batgirl didn't care either way, it meant she had the advantage in a way.
When she got to her feet, Batgirl readied herself, fully positioned to spring again if she moved, or tried anything.
"Yep." she said answered, not really in the mood for chatter. She was new in this city, but she wasn't new to the gig. And she wasn't new to a fight.
She didn't think it needed to be said that she wanted the stolen items back, chances are Catwoman just wasn't that stupid, because why else would Batgirl be hunting her down? She doubted the Cat was in the the Joker, some people were just too insane for other bad guys.
The woman was confused, or she sounded it. All movement said she was confused, so if this was just an act, it was a really good one. Make the move, assume it was real. Best time to attack was when she was still hurting.
Darting forward again, Cassandra made another shot, palm flying up to aim for the woman's jaw. Not as harsh as the first blow, not as harsh, she was already hurt. If anything, she was gentle, just enough to complete the purpose. She wanted Catwoman out cold, and enough time to grab what was stolen.
She didn't expect it to be this easy though, Catwoman was supposed to have a reputation, she'd fight back, and Bitgirl was in the mood for it. A type of challenge, someone other than the lowly thugs she'd been beating to try and find information on Terry. The sooner they got the kid back, the sooner Batman would stop worrying as much, and things would get back to normal. She didn't like it when her father figure was this worried, this distracted. The city needed them all to focus. The Joker was keeping them from doing that, this was obvious to her. But there was no point in arguing, Terry needed to be found.
