She slapped him. She had seriously slapped him in the face. He hadn't expected that. She had really been worried about him, and she didn't bother to hide how much she cared. Losing sleep over him? Torturing her? She really was guileless. He felt himself warming to her. She might have chosen Donnelly, but he was genuinely important to her. He decided to twist the knife by mentioning what happened with the Hawks - to make it clear that he had known what was going on with her personally and professionally, but that it was none of his concern. Her sneer was unexpected - like she suddenly saw him as a different, lesser person. It probably served him right that the knife ended up cutting him, too.
