Kate was not surprised by Brennan's answer. Before the Outbreak people often let their jobs define who they were so why not let being Immune define a person now. She was sure there was plenty of people who defined themselves as survivors but she could see how easy losing oneself in their immunity could be. It was a hard thankless job and if she had to do such a job without anyone to keep her grounded she was sure that she could find herself getting lost as well.
All her life people had tried to define her by the fact that she was a cancer survivor. Once they found out it was all the saw. Even her own mother had defined her by it. Kate herself had refused to fit all that she was in a little box wrapped with a bow. There was more to life and more to her than that.
All this time Kate had been keeping herself from touching Brennan but looking into his eyes now and hearing his answer she reached out and placed her hand over his heart. "But there's more to you then that. It's just a matter of find you again."
It was huge that he had admitted to not knowing. It gave her hope that he was willing to find himself again and she was determined in her promise to help. Not only that, she was curious herself to find out just who he was. She was intrigued by him.
