How do Holly's choices show her to be an independent creature?

Holly can't resist flying over the Alps, even though the rules said that fairies should travel over water as much as possible. Holly loves flying, which is not a surprise since the Book says that fairies once had their own wings. She toys with the idea of going to Disneyland Paris, one of the few places where the People could pass unnoticed. Crossing the Channel, Holly skims over the water, calling to the dolphins. Finally, the coast of the old country appears.
