Catwoman took a step back when he spoke, bringing a clawed hand up to her face as if to prove she had moxie even if the Batman caught her off guard. She had heard tales about his methods and though she would never admit it out loud, he managed to scare the living hell out of her in one swoop. After a moment to regain her courage, Catwoman straightened up and smiled at him. "I guess I should have expected bad manners from a flying rodent."
In most cases, she would have started to run before he could get in a reply, but Selina was intrigued. She made a stance like she was about to book it the hell out of there, but didn't move. Catwoman wanted to know what he was all about, even if she had to fight him for it.
