Perhaps it's a story about a potion experiment gone wrong. Hermione was working on a new potion with the Weasleys in the Weasley's family bathroom (for some reason), and there was an explosion that filled the shower area with a strange goo. So they are all in there trying to clean up the mess and reverse the effects of the potion while also having some family - like squabbles and Hermione trying to keep them all in line.
Well, it could be a completely innocent and humorous story. Maybe they all got accidentally locked in a magically malfunctioning shower room at Hogwarts. And they have to work together to get out, with Hermione using her intelligence and the Weasleys' unique skills and prank - like ideas. It could be full of banter and light - hearted moments as they figure out a solution.
It might be a story set during a camping trip. They find a hidden waterfall with a natural - made - like shower area. Hermione is a bit hesitant at first to join the Weasleys in this impromptu shower, but then they start sharing stories and having a great time. It could be about their friendship growing stronger in this unexpected and somewhat unorthodox setting.
In this fanfiction, perhaps Hermione uses her vast knowledge of magic. She might save the Weasleys from a dark wizard's attack. Maybe she discovers a powerful spell to counter a curse aimed at the Weasley family.
Obviously Hermione is one of the main characters. She's the one who might have an adventure or a problem - solving task in the shower with the Weasleys. Arthur Weasley could also be involved. His fascination with Muggle things could lead to some interesting plot points. For example, he might mistake a Muggle - style showerhead for some kind of magical artifact and accidentally cause some chaos in the shower. The Weasley kids, with their different ages and personalities, would all play different roles in the story, making it a colorful and dynamic group of characters.
One possible plot could be that the Weasleys might betray Hermione over a powerful magical artifact. Maybe they believe she has become too power - hungry in her pursuit of knowledge about it and they side with those who want to keep it away from her.
In the fanfiction, it could start with Hermione having a falling - out with her own family due to her magic. The Weasleys, seeing her distress, offer to adopt her. As a part of the Weasley family, Hermione would be involved in all their family traditions. She could bring her intelligence to help with family matters, like helping with George's business by using her logical thinking. And her relationship with Ginny would become even closer, like true sisters, sharing secrets and having girl - talk that they didn't have much opportunity for before.
One possible reason could be a misunderstanding. Maybe there was a miscommunication about something important, like a plan to fight against the Dark Arts. For example, if the Weasleys accidentally left Hermione out of a crucial part of the plan, she might be very angry.
Rather than focusing on such improper fanfiction, it's better to explore the positive and official stories in the 'Harry Potter' universe, like Hermione's friendship with the Weasleys in the proper context.
Well, in many such fanfictions, the Weasleys might protect Hermione by using their magic skills. For example, they could create protective spells around her when she's in danger. They might also physically stand in her way when she's facing threats, like some dark wizards. And they would use their family influence in the wizarding world to keep her safe from any kind of harm or discrimination.
It could be a situation where Hermione accidentally discovers a secret passage in Hogwarts that leads to a hidden room with a strange magical shower. Snape also stumbles upon it while investigating something. They start arguing about who should use it first or who has more right to be there, and through their argument, they start to understand each other better.
Well, perhaps it could be a fanfic where they are on a secret mission together. After getting dirty during the mission, they find a single shower area in an old, abandoned building. They have to take turns, but there are some magical artifacts in the shower that start causing strange things to happen. Harry might be the first to notice something odd, Hermione would try to analyze it, and Draco would be reluctantly involved.
Well, perhaps the plot could involve Harry wanting to show his gratitude to the Weasleys. He might decide to cook their favorite dishes, leading to some comical moments in the kitchen as he tries to figure out the recipes. Maybe he gets some help from the Weasley matriarch or one of the younger Weasleys.
