"Platforms have cisterns? I couldn't make out anything but the gate," he admits, worried in that sense of letting go of the worry, since... what can he do? Stockpile water in the garden carriage? There's no really sensible thought to any of it.

Instead, he turns his head to the dials (what's a dial) and knobs (interesting word, but he gets it intuitively in looking), running his fingers over them. "Something like how the sink works, isn't it."

Tapping on the small door to the shower, he didn't move to exit it or actually turn the water on. "What about drying cloths then? Where do you find those? Actually, while I have you, who does laundry? How does laundry work. There's no way the streams in the stone garden room are all we have to work with? Do people use the showers for that?"
