Today I am expecting a type of answer and logic. It started with shows like X-files (where the answeres were given by Mulder or Scully in their final reports and thoughts), CSI and like Fringe. They all have their own logic. Haven has not. This episode for example, why not just record the music that makes crazy people be normal and normal people crazy?
All that happeneds in the little town and there are few cops. They never show the badges, no paper work, she is on vacation but still can run around on official police business. The show does not explain how things happeneds, just that they do. It tries not even to explain why? The woman who control weather, boy with butterflies, or music that makes all crazy.
