[The bath here mightn't be entirely without fresh water circulating, but it did seem more likely to have the water stick around more than in a river or a bathtub. She looks back to Rei and tries to follow her lead in case she misses out on any other etiquette, starting by reaching for a sponge herself -- something she's also not used for cleaning herself before, but it seems easy enough to figure out.]

I guess that's another good reason to come with you before I tried to come as a surprise.
