Well, if you're stuck in a 'Game of Thrones' fanfiction, one way could be to look for any plot holes or inconsistencies. Maybe use them as a way to break free from the narrative. For example, if there's a prophecy that doesn't quite make sense, question it until it disrupts the story's hold on you.
You could also try to interact with the characters in a way that goes against the normal flow of the story. If everyone in the fanfic is always polite and formal, start being really out of character, like a modern - day person would act. This disruption might be enough to break the hold of the fanfic and let you get out.
You could also try to find the 'author' within the fanfiction. If it's a self - aware fanfic, there might be a way to communicate with the person who's writing it. Appeal to them to let you out. Think of it like being in a dream and trying to wake yourself up by realizing it's a dream.
One important thing to do is to make alliances. In the world of 'Game of Thrones', having friends and allies can be crucial. You can align yourself with noble houses or powerful individuals. This way, you have protection and also more influence in the events of the fanfiction. You could also try to gather information about any strange happenings or rumors that might be related to getting out of the fanfiction world.
They could try to find the source of the 'stuck' situation. Maybe it's a magical artifact or a powerful jutsu that's causing it. Once they find it, they can figure out how to reverse it.
One way might be to seek help from a powerful being in the Supernatural world, like a witch or an archangel. If they can convince this being to help them, they might be able to return home. Another option is to reverse whatever event brought them into the fanfiction world in the first place.
Naruto could try to communicate with the caster of the henge if possible. Maybe they made a mistake or can be convinced to release the henge. If not, he might have to wait for his friends to find a way. His friends could research in the village library about similar henges and how to counter them.
If you want to get out of being stuck in a girls sleepover story, you could first look for a natural break in the activities. For example, if they're about to start a new game or movie. Then say that you've had a great time but you really need to leave. You can offer to continue the fun some other time. You might also mention that you have an early commitment the next day, like a study session or an appointment, which requires you to go home and get some rest.
One important thing to do is to make alliances. Just like in the real 'Game of Thrones' series, having friends can be very helpful. Try to find characters who seem trustworthy and form an alliance with them. They might be able to help you figure out a way to get unstuck or at least survive in this fanfic world. Maybe you could team up with a character who has some magical abilities or a lot of political power.
Perhaps if she solves a major problem in the fanfiction world, like ending the feud between the vampires and werewolves once and for all, it could be the key to her getting out. She needs to think about what is the most crucial issue in that world and work towards resolving it. Another way could be to find a portal or a gateway that leads back to her own reality. This might involve some exploration and asking the right characters for help.
