Caroline remember a time she had ever seen Klaus nervous. This was certainly new for her. There seemed to be this whole other side to him when it came to his daughter. It was still so weird for her that he actually had a daughter, and to be honest she was kind of nervous too. This would be her first time meeting Hope after all. However, she wasn't going to let that show. She needed to be strong and reassuring, for Klaus.
"It will be okay," Caroline commented softly reaching out to give his hand a reassuring squeeze. "Hope belongs with you." As for the guy they sold out, yeah Caroline felt a little guilty about it. But he had been freed and it was for a greater good. Niklaus deserved to have his daughter with him.
