The floor plan was actually very useful, as it labeled rooms easily. The servants quarters and areas were simple enough, and showed evidence of a normal life--simply no...servants. Or at least nothing but vague hints of those presences they'd both sensed before.

The Basement also, however, held not only showers and a locker room, but a long corridor meant for dueling (apparently), a dojo, a swimming pool, and a simple gym. Some of it was likely primitive compared to Ahsoka's time, but modern for Trunk's own time.

The discussion of what the Force was lasted as they walked. Especially since Trunks then explained in turn what ki was. They were only just starting to get into the similarities and differences, when they found their chosen areas.
