Aunt Lemon might also impact Harry's life by introducing him to a different side of the Muggle world. Maybe she has a love for art or music, and through her, Harry discovers these aspects of Muggle culture that he otherwise would have been deprived of. This newfound interest could help him better understand the differences between Muggles and wizards and appreciate both worlds.
In the fanfiction, they could be forced to work together on a project related to lemons. Maybe there's a local fair that requires everyone to contribute something lemon - themed. Through this shared task, they begin to understand each other better. Harry realizes that Aunt Marge has her own insecurities and Aunt Marge sees that Harry is not the troublemaker she thought he was. For instance, Harry could show his creativity and intelligence during the project, impressing Aunt Marge.
There could also be other characters from the original Harry Potter series popping up. For instance, Dudley might be in there, and his relationship with both Harry and Aunt Petunia could be explored further in the context of this fanfiction. And of course, depending on the direction of the story, some of Harry's friends from Hogwarts like Ron or Hermione could make an appearance, especially if the story involves the wizarding world interfering with Aunt Petunia's life.
One interesting plot could be that Aunt Lemon discovers Harry's magical abilities before he goes to Hogwarts. Maybe she stumbles upon him using accidental magic to fix something broken in the house. She could then be conflicted between her Muggle views and this newfound knowledge, and start to secretly protect Harry from the Dursleys' worst behavior.
One idea could be that Aunt Marge accidentally eats a lemon - flavored magical treat that makes her temporarily nice to Harry. For example, she might start complimenting his schoolwork at Hogwarts instead of her usual mean - spirited remarks.
One possible plot line could be Aunt Petunia having a change of heart towards Harry due to some magical event in the fanfiction. Maybe she discovers a hidden side of magic that makes her see Harry in a new light.
In the plot, she could be a link to a part of the wizarding world that Harry has not yet explored. Say she is part of a secret society of witches and wizards. By introducing Harry to this group, it could open up new storylines such as learning new types of magic, getting involved in political intrigue within the wizarding world, or even finding new allies in his battle against Voldemort.
Maybe in the fanfiction, Aunt Lemon has a hidden magical past herself. So when Harry comes to live with her, she starts to teach him some ancient spells that she learned long ago. This would add an interesting layer to their relationship as they bond over magic that is different from what Harry learns at Hogwarts.
Through shared secrets. For instance, if Harry discovers something about his family that he doesn't want others to know, and he confides in Aunt Lemon. This would create a bond of trust between them.
If we consider a non - adult take on 'lemon' in fanfiction, it could be about a bright, citrus - like charm or potion that has some significance in the story. For instance, a lemon - scented potion that is used to enhance concentration during exams at Hogwarts. This kind of fanfiction can be light - hearted and family - friendly.
