There could be many authors. It might be a new writer in the fanfiction community who wants to explore this rather dark and emotional side of their relationship.
In a fanfiction, it could be that Percy gets influenced by some sort of magic or external force that makes him act coldly towards Annabeth. He starts ignoring her and when she tries to confront him, he says some mean things. Annabeth, who is used to Percy being her support, would be heartbroken and cry.
One way could be that Percy realizes his mistake right away. He quickly apologizes to Annabeth, explaining that he was just having a bad day or was influenced by something he didn't understand. Annabeth, being in love with him, would probably forgive him after some time.
Annabeth could also try to solve the problem that's making Percy cry. If it's related to a quest or a danger, she'll start thinking of ways to fix it. In some fanfictions, she might say 'Don't worry, we'll figure this out together.' and then start making a plan.
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.
In fanfics, Percy might cry for Annabeth because he loves her deeply. Their relationship is complex and full of shared adventures and near - death experiences. If Annabeth is in danger, like facing a powerful monster or trapped in a deadly maze, Percy's fear for her safety can lead to tears. It shows his vulnerability and how much she means to him.
For a Percy and Annabeth fanfiction to be considered the best, it should have an engaging plot. Maybe it takes them on a new adventure that still feels like it could be part of the Percy Jackson universe. It should also explore their relationship in a meaningful way. Like showing how they support each other during tough times or how their relationship grows. Additionally, unique takes on their powers or the world they live in can make a fanfiction stand out. For instance, if the author gives a new spin on Percy's water powers or Annabeth's strategic thinking, it can add a whole new layer of interest to the story. And of course, the chemistry between Percy and Annabeth needs to be palpable, just like in the books.
In fanfiction, their shared experiences play a big role in making them soulmates. They've been through so many life - threatening situations together. These experiences have created a deep emotional connection that can be seen as a soulmate connection. Also, their mutual respect for each other's abilities is important. Percy respects Annabeth's wisdom and Annabeth respects Percy's strength. This mutual admiration is often a characteristic of soulmates in fanfiction.
One aspect that makes Percy and Annabeth fanfiction beautiful is the way it can expand on their backstories. Authors might write about their early days at Camp Half - Blood, the challenges they faced, and how they grew closer. It's also beautiful when fanfictions show their growth as individuals within the relationship. For instance, Percy becoming more confident in his leadership skills with Annabeth by his side, and Annabeth learning to be more open - hearted. Moreover, the love and loyalty they have for each other are often portrayed in a very touching way in fanfiction.
