Dirk's step falters just a bit at human mating rituals, because that was really not what he was expecting from Daneel when he'd mentioned research. History, maybe, or the migratory patters of local birds, not mating.

He just manages to keep his pace, and looks over at Daneel, eyebrows raised. "Mating rituals." And then it clicks. Ned had said that he and Daneel were dating, hadn't he? Daneel must be doing some research of a more personal nature. Dirk's not sure that romance novels are the best place to look for realistic dating advice, or himself the best person to help find them, but if that's where he wants to start...

"...Anything in particular you had in mind? Specific facets of the...dating experience?"
