She knew her course of action before it could even begin. She tilted her body to the side, her arm flying up beside her face to take the impact of the kick. Pain was felt, but it didn't really register. She'd felt worse pain, and Catwoman wasn't at her best. A bruise, maybe, on her arm, at the very most, but the protection in the suit would probably help at that. It wasn't often Batgirl came home with a bruise, she wasn't about to start now.
Her eyes narrowed, not really in the mood to play games. End this, grab the bag, get back to work. When Catwoman's leg hit her arm, Batgirl's other arm reached around grabbing a hold of the leg, before holding on with the other arm. She yanked back, trying to throw Catwoman off balance, before using the lack of anything secure to stand on to slam her back into the ground.
Every move Batgirl counted the many possible ways to kill her, and the many ways she wouldn't. She would always hold back, and while sometimes unleashing felt...amazing, this wasn't the time.
"The bag." she demanded. Batgirl would not have any trouble beating Catwoman to the point she couldn't move, and then just taking the bag. Actually, that would be the more fun way to do things, but she was always willing to play nice once.
