I am quite fluent in spanish, but I have a question. A few days ago I was watching Pan's Labyrinth. When Faun would speak to the little girl, he'd talk to her using vosotros. Well, it's my understanding that vosotros is used just like ustedes, as in, when talking to two or more people. However, he was using it speaking only to her. Am I wrong? Could it possibly be something saved for extreme cases? Everyone I know speaks using tu, or usted if they're speaking respectfully to someone. But I've just never heard of vosotros being used in a singular form.
