It's possible that there are new family members or situations that have shifted the family's focus. For instance, a new baby in the family might draw all the attention, or a family financial crisis could make his parents more concerned about other aspects, causing them to neglect Edward.
There could be a misunderstanding within the family. For example, they might misinterpret Edward's needs or assume he is more self - sufficient than he actually is. This could lead to them not providing the care and attention he requires.
His parents could be too busy with their own lives. Maybe they have demanding jobs or are preoccupied with their own personal matters, leaving little time to attend to Edward.
He might withdraw into himself. Edward could focus more on his own internal thoughts and interests, like spending time reading or exploring his own talents that have been overlooked at home.
Sally could be in a new relationship or have new friends that are demanding a lot of her time. As a result, she may not have as much time or energy to devote to Percy, which unfortunately comes across as neglect in the fanfiction.
Well, Percy is often neglected in fanfiction because he doesn't have the same kind of popularity as the main characters. In the books, he's not part of the core group that goes on the big adventures. He's more into the rules and regulations of the wizarding world. Fanfic writers usually prefer to write about characters who are more involved in the action - like Harry facing Voldemort. Percy's role in the official story is more of a background one in terms of the main plot, so it's easier for him to be overlooked in fan - created stories.
One possible reason could be his own missions and responsibilities. Jiraiya is often away on important spy missions or gathering information for the Hidden Leaf. He might be so caught up in these tasks that he unintentionally neglects Naruto.
It could also be due to misunderstandings. Fanfiction often plays with the idea of miscommunication between them. Maybe Bella misinterprets Edward's over - protectiveness as a lack of trust in her ability to handle vampire - related situations. Or Edward might misunderstand Bella's need for independence as a sign that she doesn't love him as much as he thought. These misunderstandings can escalate into arguments.
One reason could be a misunderstanding about their family's future. Maybe Edward has a vision of how the family should evolve that Carlisle disagrees with. For example, Edward might want to expand the family in a different way than Carlisle.
It could also be that the Potters are under some sort of magical influence or curse. In the fan fiction world, there could be a dark force at play that makes them see the twins as more important. This force might be manipulating their emotions and perception, leading to the neglect of Harry.
Another possibility could be a new character created specifically for the fanfiction. This new character might have unique abilities or a personality that attracts Edward in ways Bella didn't. For example, she could be a vampire from a different coven with a very different view on life and love, which makes Edward question his feelings for Bella and consider this new character as a potential mate.
Another possibility is that he underestimates the importance of family. Tony has always been focused on his own achievements and the big - picture stuff. He might not realize how much his daughter needs him until it's too late.
Maybe he's too caught up in his work. Tony Stark is often depicted as a workaholic, so he could be so focused on his inventions and saving the world that he simply doesn't have time for his son.
