Maybe Percy feels worthless because he constantly compares himself to others. In the fanfiction world, there could be characters who seem to have more power or popularity, making Percy feel inferior.
It could be due to past failures that haunt him. If he had some big setbacks in the story, like losing a battle or failing to protect someone, those memories might make him think he is not good enough. For instance, if he let down a friend in a crucial moment, he might question his entire worth.
Percy is very brave. He doesn't hesitate to jump into dangerous situations, and Annabeth knows that he'll protect her. So his courage makes her feel safe.
He probably feels a bit scared. Hogwarts is a big and strange place, and without his family, it can be intimidating.
Percy might feel a deep sense of contentment. He and Annabeth have a special bond, and having her trust him enough to sleep in his lap could make him feel warm and happy inside. He may also feel a bit nervous, not wanting to move and disturb her peaceful slumber.
One reason might be related to his sense of responsibility. Naruto feels a huge obligation to protect the village and his friends. In fanfiction, when things go wrong or he fails in some small way, he could start to feel undeserving of all the good things in his life. He might think that if he can't fulfill his duties perfectly, he doesn't deserve the love, the power, or the status he has. Also, his own high standards for himself, which he has developed over the years of trying to prove himself, can make him feel unworthy when he falls short in any way.
One reason might be his relationships. If Percy has deep and complex relationships with other characters, whether it's friendship, rivalry, or love, it gives a lot of room for fanfiction writers to explore different scenarios. For example, if he has a love - hate relationship with a character, writers can create all kinds of stories around that dynamic. Also, his abilities or powers could play a role. If he has unique powers, writers can come up with creative ways to use those powers in new storylines, which makes him a popular choice in fanfiction.
Maybe it's because of something he did that had unexpected consequences.
One reason could be that Triton realizes Percy is a key figure in the grand scheme of things. Percy's actions have far - reaching consequences for the balance of power in the mythological world. Triton, as a figure in this world, is affected by these changes. He might cry for Percy because he sees Percy as a symbol of hope or a potential savior. And yet, he also knows the great burden that Percy has to carry, which makes him sad.
One reason could be its complex web of characters and plotlines. Fanfiction often features a large number of characters with their own stories intertwined, just like in Game of Thrones. There are so many different houses, characters, and sub - plots that it gives a sense of being a creation by a passionate fan rather than a more streamlined traditional narrative.
Well, it could be that the fanfiction author has created a unique backstory. For example, Snape could have saved Hermione's life at some point in the past, and she now has this deep - seated sense of security around him. Also, he might be a source of knowledge for her, and his presence, while initially intimidating, becomes reassuring as she realizes he won't let harm come to her in matters related to magic and the school.
In some fanfictions, Naruto might feel left out because he has a unique background. He was an outcast in the village at first. Maybe the other characters in the fanfic are forming groups or having relationships that don't include him. For example, if there are new teams being formed and he's not part of them, it could make him feel left out.
