I want the hero to gut the princess so badly and rip out her organs without anaesthesia. And then cut out her nerves like that controversial fish dish in east Asia.
Also, she killed a pregnant woman, so her uterus must be ripped out and be used as a container to breed flesh eating bacteria so that they go to the princess and spit out her flesh since it's not worth consuming. Excuse me for the gorey rant.
This should have an incest tag
