The awareness of what a sprite was was a welcome one. Good. Bill had variously either identified with, or been forcibly identified as, a demon, a god, a muse, a being of ill repute... Sprite or fairy was somewhat new and hopefully would be less threatening, at least for people who didn't know their fairy lore too well. "I only have a few rules!
