Water obviously had important uses for organic life, and so finding a way to move on and through it was actually pretty clever - or maybe it was just such a necessity, she thought, that even humans could come up with it. "Well, I'm sure if there were bodies of water on Homeworld, there would be waterships there, too," she decided, her tone haughty - though in the back of her mind, she couldn't help thinking that she was already lousy at being a Crystal Gem. Still... Just because she could see the value of Earth, and liked a handful of its inhabitants... She didn't have to turn into Rose Quartz or anything.
