Princess Annabeth is often depicted as highly intelligent. She uses her wits to solve problems and strategize. For instance, when dealing with threats to the kingdom, she can quickly analyze the situation. Prince Percy is usually brave. He doesn't shy away from danger and is always ready to fight for what's right. In many fanfictions, he might be the first to charge into battle to protect the princess or the kingdom.
One common theme is love against all odds. Their different kingdoms or social statuses might create barriers, but they always find a way to be together.
Prince Percy was known for his bravery and Princess Annabeth for her wisdom. In the fanfiction, a great evil threatened their kingdoms. Percy wanted to fight it head - on with his sword, but Annabeth advised caution. They argued at first, but then realized they needed each other.

Perhaps they are from rival kingdoms that have been at war for generations. They meet by chance in a neutral territory and instead of fighting, they start to talk. They realize that the war has been caused by misunderstandings between their families. So, they decide to work together to end the war. They face opposition from their own families and kingdoms, but their love for each other gives them the strength to persevere and bring peace.
Perhaps Percy kidnaps Annabeth because he has been misinformed about her. He might believe she has done something terrible, like betrayed the demigods or the gods themselves. As the story unfolds, he discovers the truth, that she has been framed, and then they have to work together to clear her name and stop the real wrongdoers.
In a large number of Percy and Annabeth fanfictions, they are indeed presented as soulmates. Their shared adventures, the way they understand each other without many words, and the deep loyalty they have for one another all contribute to this perception. Fanfiction authors often build on their existing relationship from the original works and enhance it to the level of soulmates. They might show it through things like Percy being able to sense Annabeth's distress from afar, or Annabeth always knowing exactly what Percy needs in difficult situations. This soulmate - like relationship makes for very engaging and heart - warming stories in the fanfiction realm.
It could be that Annabeth has a misunderstanding about Percy. She might think he's a threat to her position or status at the camp, so she bullies him to try and keep him in check.
It could be Chiron, the centaur. He's always keeping an eye on the campers and would likely be concerned if he caught them up to something. He might give them a stern talking - to and some extra chores as punishment.
Percy might be a bit flustered and embarrassed. He's protective of his relationship with Annabeth, so having Magnus walk in might make him feel like their privacy has been invaded. He could quickly try to shield Annabeth or just look really shocked.
Their shared experiences play a big role. They've been through so much together, like countless battles and adventures. Percy has seen Annabeth in tough situations and he knows how strong she is, but also how vulnerable. So he feels the need to protect her. For instance, they might have had a close call in a previous adventure where Annabeth was nearly killed, and that memory makes Percy extra vigilant.
