God, he was a lucky bastard (who may have had more than that cop of joe). He'd won the Partner Jackpot, for sure. She was smart as hell, gorgeous as hell, and apparently had more of a sense of humanity than he'd iniatially expected, judging by how quick she agreed to do him a favor. He didn't really get that. Well, he did, because of the whole quest for truth, but he didn't get why she was so willing to do a favor for him, he didn't think they were at that point in their partner-ship.
And to add to that their conversation in the dinner, and her not thinking it was a waste of time. He was luckier than he should be.
