My fanon: After deeping one’s understanding of water (the base ingredient of most potions) by BEING water and returning to one’s natural form, it is psychologically advisable to reestablish ones normal relationship with water by directly interacting with it in ways one often does. Hoof-washing dishes, swimming, playing in a sprinkler, or, as seen here, showering/bathing.
Flowing with.
Disolving into.
Floating on top of, but like oil, rather than a seal or human swimmer.
What would be non-normal water relationships to you?
