The reconciliation could happen simply with an apology. Percy might be the first to say he's sorry for being so stubborn during the fight. Annabeth, seeing his sincerity, would forgive him and they would hug it out, realizing their relationship is more important than whatever they were arguing about.
Maybe they are both at a loss after the fight. But then they are given a task that requires their combined skills. As they start working together, they begin to remember why they are good partners. Small exchanges of glances and smiles lead to a conversation where they both admit their faults and make up, with a new understanding of each other.
They could start by talking it out. Percy could apologize for his part in the fight, like if he was too hasty or inconsiderate. Annabeth, in turn, could admit if she overreacted. Simple communication is often the key to resolving disputes.
Perhaps jealousy plays a part. If Percy got a bit too friendly with another character, Annabeth might get jealous and they fight. However, they soon remember their strong bond and how much they mean to each other, so they make up. It's a common trope in fanfiction as it shows the depth of their relationship.
In a fanfiction scenario, Percy and Annabeth are in a new magical realm. Percy wants to immediately explore a mysterious, dangerous-looking cave because he senses there might be something important inside for their quest. Annabeth, being the more cautious one, opposes it, saying they need to gather more information first. They have a heated argument. But when Percy accidentally triggers a trap near the cave entrance, Annabeth saves him without hesitation. This makes Percy realize that he should listen to her more, and they make up.
In fanfiction, they might break up because of outside pressure. For example, if the gods or some powerful force tries to keep them apart for some reason. However, their strong bond and shared memories would eventually lead to their make - up. Their adventures together, like the time they spent in Tartarus, are so significant that they can't stay apart for long.
Another reason might be the stress of their quests. They are constantly under pressure to save the world or their friends. This stress can build up and cause them to lash out at each other. For instance, if a quest isn't going well and they keep hitting dead ends, they might start blaming each other for mistakes made along the way.
Another reason could be jealousy. Suppose Percy was getting a lot of attention and praise for his recent achievements, and Annabeth felt overshadowed. Her jealousy could fester and turn into a desire to undermine Percy, leading to her betrayal. However, this would be a more complex and less noble reason compared to the others.
If their fight is really bad, it could create a rift between them for a while. They might avoid each other, which would be hard since they are usually so close. This could make it difficult for them to work together on future quests.
One possibility is that it could lead to Percy's downfall. If Annabeth, who has been his close ally and friend, betrays him, it might shatter his trust not only in her but also in others. He could become more isolated and vulnerable, making it easier for his enemies to target him.
Well, it could be that Annabeth and Percy meet in a different setting than in the original stories. For example, they could meet in a modern city but still have to deal with their demigod issues. They might discover new powers or abilities within themselves as they interact. And there could be some romantic moments as their relationship often has that element in fanfictions.
A Percy and Nico fight in fanfiction might be a complex affair. Their respective loyalties could come into play. Percy is loyal to Camp Half - Blood and Nico has his own complex allegiances. They could be fighting because of different ideas about how to deal with a new threat to the demigod world. Percy might think of a more upfront approach using his powers, while Nico could be more inclined towards using his knowledge of the Underworld and the dead to outwit the threat. This difference in approach could lead to a fight between them as they try to impose their methods on each other.
