@Cessika exactly, stop treating them like just some characters on a page. They are flesh and blood, they get hungry, they need sleep, they breathe, they bleed when hurt, so they have emotions and they feel things.
But to her they are only characters that she created and the story should flow as per what she wrote, then why does she want to change Fiona's character arc and story? Just because she is possessing her? Isn't that selfish? If you want the story to be exactly as it was written then let Fiona suffer her fate. But did she do that? No, of course not! Then why does she want the other characters to behave and live only the way she wrote the story? Isn't that contradictory?
