I think Diana's response is probable the writers' tongue in cheek way of showing Diana is no different from actual kids who "know it all" because they have stopped believing in people like Santa and the Easter Bunny etc so they can come across as grown up. In this universe I find it impossible that fairies don't actually exist. There must be a wesen equivalent of one since this show was based on fairytales. Had they continued with this original premise, I'm sure we would have seen one.
