Natsu might need to prove through his actions that he has changed. For example, he could start being more respectful, listening to his girlfriend's feelings, and giving her space when she needs it. It would take time and effort to rebuild the relationship, but it could be possible if both are willing.
One way to resolve it could be through communication. If Alice is a person, she should be made aware of the harm she has caused to the fanfiction. Then, she could apologize and take steps to correct her actions, like removing any unauthorized use of the fanfiction.
The abuse might also lead to a cycle of revenge or retaliation in the story. The girlfriend could seek to expose Natsu or take actions that would harm his reputation. It could also potentially lead to a path of redemption for Natsu if he realizes his mistakes and tries to make amends.
Another solution could be a direct rescue. The heroes could use their powers or skills to overpower the kidnappers. Barry could speed in and disarm them before they even realize what's happening. Or perhaps Cisco could use his tech to create a distraction and free Sam.
They could each write their own version of the fanfiction based on their ideas and then combine the best parts. This way, they both get to have their say in how Harry is presented and what happens in the story, and it could lead to a more interesting and inclusive fanfiction in the end.
One way is to rework the Pokemon's abilities. If it was disqualified due to overpowered abilities, tone them down to fit within the story's framework. For example, if a Pokemon had the ability to instantly defeat all opponents, limit it to only being able to do that in certain rare circumstances.
They could start by having an honest conversation. Just sit down and talk about what made them glare at each other in the first place. By communicating openly, they can clear up any misunderstandings.
If it was consensual, they might consider counseling to deal with the complex situation. They need to think about the future, whether it's about raising the child together or other options like adoption. And of course, the doctor may face professional consequences and need to go through proper channels in the medical community to address those.
Perhaps a bigger threat or a common enemy could emerge. This would force the three of them to work together more effectively. Sakura would then realize that hitting Naruto is counter - productive and Sasuke would be glad that the situation has changed. For example, if a powerful new enemy attacks the village, they would need to focus on defending it together rather than internal squabbles.
The first step would be for the dad to realize his mistake as soon as possible and apologize sincerely to his daughter. Clear communication is key. He should explain that it was a genuine error and not intentional.
She could also talk to the author of the fanfiction. Maybe there was a misunderstanding or the author could clarify some things that are scaring her. For instance, if it's about Percy's character, the author could explain their creative choices.
