And then, of course, she had a reason to work with him, and he with her. It really wasn't fair, the way they kept getting thrown together. She knew there was more to the FBI story, and that was dangerous. He'd really like to confide in her, and it looked like he might have to. If she got on the FBI's radar independently, there was only so much he could do, and it looked like her patient knew something important.
For the first time, he realized that if she found out about the FBI sting, it would probably destroy what remained of their friendship, and it would definitely obliterate any trust he had rebuilt. The worst thing was, it was starting to seem like it was not a question of if she found out, it was a question of when she found out.
When they found out the patient had killed himself, they were all stunned. He knew she'd taken it hard, and wondered what that night had been like for her. The next day during a meeting in Connor's office, he saw for himself how sad and guilty she felt. She left for her office, and as soon as he could make his escape, he took off after her. He tried to console her, but he froze when he saw her in tears. He didn't know how to respond because what felt natural - to give her a big hug, like she would have given him - seemed too intimate.
There was so much going on that he was only slightly aware that he had seen Sam flirting with several women in the office the next day. Maybe those two were over.
