That sort of death wish was so utterly alien to everything that Jack Sparrow believed in. He had recognized it in Norrington when that man chased him through the hurricane and was found wanting. He had seen it in some who went to the gallows, tired of running from the powers that be and looking for rest; had seen it in the eyes of a young widow in Spain when she took him into her bed that night, hoping he was that kind of pirate. Disappointed in the morning, when he left her alive---alive and thus unsatisfied.

He didn't suspect it or anything like it in Buffy, now. Instead, he was enjoying that feeling of helplessness and trust that her touches tended to inspire. Moments like this, Jack Sparrow would be or do or say anything she wanted of him---persuasion.
