Asylum by Skimaskmaster reviews
Sam and Dean Winchester have only one lead that indicates trouble at Mount Massive Asylum: The Whistleblower. Legend surrounds that place and it's only natural that Sam and Dean think that it's the supernatural and not a serious case of nutcases ruling the mental asylum. All that has to be said is that Miles is sure happy to see them. Rated T for mild swearing, mild gore.
