I loved that both of them are trying to wind each other up, every time they're in contact, even when they're not together. Their jobs and that they're good at them. That they're both thinking and acting like adults, and that they can't stay away from each other. Also, that they're not sure of each other, or themselves, but just try, anyways, because they can't not. And I like them moving apart and together again, as they try to sort their feelings out. I found the opening bit somewhat confusing, though. Was he meant to be the one with the letter-opener/headwound?
