She wasn't just good. Cassandra was one of the best. At least in her world. And it when it came down to fighting one on one, no tricks, no powers, she was willing to bet she was one of the best in this world too. She was at the top of the 'just human' fighters. When the door opened, she didn't stop right away. She knew Terry was there, but gave it a few seconds. She finished what she was doing, and then turned to watch the figure of Talia again, this time joined by her sister. At least it wasn't the two of them here.
"I'll be done in half an hour." she said flatly, then turned her gaze to Terry. There was a thin sheen of sweat over her body, she'd been moving none stop for a while, but her breathing was even.
She wasn't quite in the mood to deal with him. It amazed her, how he could have so much. Be given so much, have everything she'd ever really wanted, and he seemed completely ungrateful for it. Like a bratty teenager. It didn't sit well with her. All attention was on him, and she didn't understand what he did to deserve it. Still, she never voiced these opinions, and tried to keep herself as neutral as possible. Which was probably causing the tension. They just didn't get along.
It was almost like Nightwing all over again, only Dick she knew, and knew he was good. He just didn't trust her. She couldn't blame him, after what she'd done, even if it hadn't been her fault. Even if she made up for it. She had to half wonder if she'd ever get along with him. At least she could carry a conversation with Tim.
