One scenario could be that Harry Potter accidentally breaks a family heirloom of the Weasley family while at the Burrow. Molly, who treasures her family's possessions, would be very angry with him. Another possibility is that Harry gets into a fight with one of her sons, like Ron, and Molly takes her son's side, getting mad at Harry for starting the argument.
It could be that Harry uses his fame in a way that Molly finds inappropriate. For example, if he uses it to get special treatment at Hogwarts and it affects other students negatively. Molly, who believes in fairness, would not like this behavior from Harry. Or if Harry refuses to listen to Molly's advice regarding a magical problem he is facing, thinking he knows better, she would be angry as she is trying to help him.
It could be that Harry made a decision that went against Molly's values. Suppose Harry started using dark magic or got involved with some unsavory characters, Molly, being a morally upright witch, would be furious with him. She might feel that he is setting a bad example for her kids or bringing danger to their world.
One possible reason could be that she might think Harry is putting himself in unnecessary danger, like when he goes off on his own to face Voldemort without a proper plan. Molly is very protective, and she may feel frustrated with Harry's recklessness.
One possible storyline could be that in an alternate universe, Harry Potter and Molly Weasley develop a relationship over time. Maybe Harry is in need of a motherly figure after all he has been through, and Molly's nurturing nature draws them closer. They might face opposition from the wizarding community as it goes against the norms.
One possible reason could be a misunderstanding. Maybe Molly does something that Harry misinterprets as a threat to his friends or his mission. For example, if Molly tries to keep Harry from a dangerous but necessary task, Harry might see it as her overstepping and feel the need to 'punish' in the context of the fanfiction, which could just be a strong rebuke or some form of isolation within the story's plot.
In some fanfictions, Ginny might be under the influence of a powerful and dangerous spell. Harry, with his knowledge of magic and his strong will, might search for a counter - spell all over the wizarding world. He could enlist the help of his friends, like Hermione and Ron, to finally break the spell and save Ginny. It could also be that Ginny is kidnapped by a group of Death Eaters, and Harry embarks on a dangerous mission to find their hideout and rescue her.
One great Molly Weasley fanfiction is 'Molly's Moments'. It shows her behind - the - scenes efforts in taking care of the Order of the Phoenix members at the Burrow. Another is 'Molly's Motherly Love' which delves deep into her relationship with each of her children, especially during the tough times of the wizarding war. There's also 'Molly's Magic' that focuses on her underrated magical abilities.
It could be due to jealousy. Perhaps Ginny has been spending a lot of time with another character, and Harry misinterprets their relationship, leading to his anger. In fanfiction, the writers often play with such emotions to create drama.
In fanfiction, Molly Weasley is often depicted as a strong - willed and loving mother figure. She is shown as someone who is extremely protective of her family, just like in the original books. For example, she might be portrayed as being very strict when it comes to the safety of her children, especially during dangerous times in the wizarding world.
The relationship could start with mutual respect. Harry has always respected Molly as a mother figure in the Weasley family. This could gradually turn into something more romantic as they share more personal experiences. For example, Harry might confide in Molly about his post - war traumas, and Molly's understanding and care could lead to deeper feelings.
Well, there could be a plotline where Molly discovers a long - lost relative of Harry's and they go on a journey together to find out more about his family history. This would involve them exploring different parts of the wizarding world, meeting new characters, and learning secrets about Harry's past. It would also give Molly a chance to be more of an adventurer rather than just a mother figure, and it would strengthen her bond with Harry as they share in this discovery.
