I struggle with the idea that any parents would say "yes, we should absolutely bring her home rather than leave her in a hospital, ideally one with armed guards and maybe an exorcist on staff."
I know that you're joking, but it's also absolutely what a Health Care Insurance company would DEFINITELY try to pull.It makes since that a US HMO would deny payment though. "I'm sorry, you would need to be Platinum Plus level to receive coverage for any curses over 500 years old."
