To make it quick, my main character dressed up in a silly costume, armed herself with a sword and killed two people. She tried explaining her act by telling a rather crazy story about another world, demons, an evil in the city and so on. Naturally, she was thrown into a mental institution. But a few years later, someone discovered that she was telling the truth and needs to get her out. How would this work? There is a doctor in charge, so I assume he will have to sign her release papers. But can she be set back on the streets, or will she be transfered to a prison instead? She did kill two people, after all. I'm not sure what country the story is set in, but that's not really relevant. Is it enough that the doctor believes her, or does he have to convince someone else too? She has been there for years, so releasing her out of the blue because "she is healthy now" might sound suspicious. But at the same time, the doctor can't reveal the proof to anyone. He could perhaps help her escape, but if so, how?
