It could be Audrey, as she is Percy's wife in the original series. In fanfiction, they could have a more in - depth relationship story leading up to the birth of their son.
One possible plot could be that Percy's son is starting at Hogwarts and is having a hard time living up to his father's reputation. He might struggle with the expectations placed on him due to his family name. Maybe he doesn't have the same academic prowess as Percy did at his age and has to find his own way to shine in the wizarding world.
It could be one of the Weasleys from the Harry Potter series. Maybe Ron Weasley, who is known for his love of reading (although not specifically mentioned as reading fanfiction in the original books). It could also be a fan - created Weasley character in a fanfiction world who has this rather odd reading habit.
One challenge is getting their personalities right. Arthur is very curious about Muggle things and has a warm, fatherly nature. Ginny is strong - willed and brave. It can be difficult to make sure these traits are consistent throughout the story. Another challenge is creating a believable relationship dynamic between them. Since they are father and daughter, it has to be a relationship that feels true to the original series.
There could be some really interesting fanfiction ideas around this combination. The Weasley family is known for their unique and often humorous take on magic. Maybe in such a fanfic, Arthur Weasley could be passing on some old family wisdom about a lemon - like it has some special property in magic that Rose Weasley discovers. It could be a story of discovery and family bonds, with the lemon as an unexpected element that ties the plot together. But again, it would take some digging to find such a specific fanfic.
One interesting aspect is their family dynamic. In fanfiction, we might see how their relationship changes as they grow older. For instance, Ron becoming more protective of Ginny as she starts dating. Another aspect could be their individual growth. Ginny might be shown becoming a more powerful witch, and Ron could be seen maturing in his understanding of magic and the wizarding world.
One possible plot could be that Rose Weasley is doing some experimental magic in the Weasley family home. Arthur Weasley, being the curious and experienced wizard he is, comes across a strange lemon - like object that Rose has. It turns out this 'lemon' is actually a magical artifact from another time. They then embark on a journey to figure out its origins and how to use it safely.
There's also a chance that she'll be hurt. Mrs. Weasley has a big heart and Harry ignoring her could really wound her. She might then become more withdrawn herself, focusing on taking care of her own family and leaving Harry to his own devices, while still secretly hoping he'll come around.
Adventure themes are quite common too. Given the magical world they live in, Acio Weasley might be on a quest, solving mysteries, or fighting against dark forces. This could involve exploring new parts of the wizarding world, using magic in creative ways, and facing dangerous challenges along the way.
