How does Percy's change after Tartarus affect the plot in fanfiction?

He could be more cautious. The perils of Tartarus might have made him less reckless. For example, he might think twice before getting into a fight or taking risks that he used to take without hesitation.

Well, they would probably communicate better. In Tartarus, they had to rely on clear communication to survive. So, back in the normal world, this would carry over. They'd be more open about their feelings, fears, and plans, which would strengthen their relationship in a more emotional way.

On the other hand, his experience in Tartarus could also make him more empathetic. He has endured so much pain that he might be more in tune with the suffering of others. He could be more likely to reach out to those who are in difficult situations, knowing what it's like to be in a seemingly hopeless place like Tartarus.

It makes him more hardened. The harsh conditions force him to become tougher both physically and mentally. He has to constantly be on guard and ready to fight, which sharpens his reflexes and his ability to think quickly in dangerous situations.

In some fanfictions, their relationship could become more complex. They might have seen sides of each other in Tartarus that they didn't expect, and it could cause some friction. But at the same time, they also have this unbreakable connection because of what they've been through. They might argue more about how to deal with the after - effects of Tartarus, like Percy wanting to just forget and move on while Annabeth wants to analyze and learn from it. However, in the end, they still love each other deeply.

His relationships with his friends could become stronger. When he eventually gets out, his friends might see him as even more of a hero for surviving Tartarus alone. They could respect him more and he might be more confident in his relationships.

In some fanfictions, Percy might be more withdrawn. He has seen the horrors of Tartarus and it could make him less trusting of the world around him. He may also have new powers or a deeper understanding of his abilities that he gained from the experiences there.

Often, their relationship is shown as deeper and more unbreakable. They've been through Tartarus together, which is like the ultimate test. So in fanfiction, they trust each other completely and are always there for one another.

Luke's possessiveness can change the alliances in the fanfiction. Other characters might side with Percy against Luke, or some might be influenced by Luke's possessive behavior and turn against Percy. This reshapes the power dynamics in the story.

It could also drive Reyna to focus more on her own development. Maybe she decides to prove herself even more without Percy's affection. This can lead to her taking on new challenges and growing as a character in the fanfiction. She might become more independent and self - reliant.
