Of course he worried. He worried about her like she worried about him. It was just that he knew what he was doing and she didn't. That's why she wanted to be taught. "I know you would.. you have. But I don't want you to have to do that." What was she supposed to do? Not only stop pissing people off, but stop talking to Frank, or Matt or Jessica or anyone else who had super powers and who dealt with violence all the time? The only person she would have left then was Foggy, and he was too busy being a big time lawyer. "Don't tempt me," she countered, squeezing his hand in return with a smile.
Karen just nodded her head and stopped along with him, having expected that bombshell to get him to stop in his tracks. She thought about saying something smartass like 'well he wears a mask so' but she didn't. "He's not like you or the others, out in the open. Telling everyone who you are. Trust me. I was.. the same, when he told me. Which I mean, if you want to hit him, you have my full permission. Him and his secrets." She sighed a bit.
She squeezed his hand again. "You just go on acting like everything is normal. Or try to. That's all you can do. I'm here. I'm not going anywhere."
