Well, in some fanfictions, it could be that they're under the influence of some dark magic or a spell that makes them turn against Hermione. Or perhaps they're misinformed about her actions at Hogwarts and think she's a bad influence. Also, some writers might use it as a plot device to create a rift and then build a story around Hermione trying to fix things with her parents.
Well, it could be possible in some really out - there fanfictions. Maybe some writers want to create a lot of drama. They might think that if Hermione's parents suddenly turn against her, it can add some really intense emotional turmoil to the story. But in the original books, Hermione's parents are really supportive.
One interesting aspect of Hermione Granger and her parents in fanfiction could be exploring how their Muggle background affects Hermione's Hogwarts experience. In some fanfictions, her parents might be more involved in the wizarding world than in the original series, which adds a new dimension to Hermione's story.
There could be some underlying mental health issues within the family. Perhaps her parents have some undiagnosed conditions that make them more prone to lashing out. In the fanfiction world, this could be explored further, like how Hermione tries to understand and deal with this aspect of her family situation while also dealing with the abuse.
One great Hermione and her parents fanfiction is 'The Granger Family Reunion'. It beautifully explores the relationship between Hermione and her parents in a post - war scenario. The story delves deep into how they cope with the changes in Hermione's life due to her experiences at Hogwarts. Another interesting one is 'Hermione's Muggle Roots', which focuses on how Hermione's parents influenced her values and her journey in the wizarding world.
In such a fanfiction, it would have a huge impact. Hermione would likely feel a great sense of loss and isolation. She might become more withdrawn and self - reliant. Her relationships with her friends at Hogwarts could also change. For example, she might be more hesitant to open up or more desperate for their acceptance and support as she has lost the most important people in her life in her muggle family.
Her parents might be in danger. Since Voldemort was after her, now that they remember her, they could become targets. The Death Eaters could use them to get to Hermione.
One popular theme is family reconciliation. Since Hermione is often so involved in the wizarding world, fanfictions might explore how she reconnects with her Muggle parents after a long time. Another theme is the discovery of Hermione's family's hidden magical heritage. It could be that there are some secrets about the Granger family that are revealed in the fanfiction.
One possible reason could be social class differences. Hermione's parents are Muggles and might view Ron's large, wizarding family with some prejudice. They may see the Weasleys as a bit chaotic and irresponsible because of their financial situation.
Hermione's friends would likely be very excited. They might plan some special activities for her parents. For instance, they could arrange a little tour of the Forbidden Forest (from a safe distance, of course). They would also share stories about Hermione at Hogwarts, how smart she is and all the adventures they've had together. And they would be happy to answer any questions Hermione's parents had about the wizarding world.
