Kara squeaks quietly in surprise when he bumps into her. She was lost in thought, worrying about things she couldn't possibly do anything about. When she wasn't paying attention it was as easy to catch her by surprise as anyone else. She spun to make sure he was okay.

"Oh, I'm sorry! Are you alright?" It had never been a problem before, but she was far stronger than she looked. She didn't want to take the chance that he had bumped into her because he was injured or that she had made it worse.
