Perhaps Molly catches the sadness in Harry's eyes or hears the tone of his voice when he thinks no one is listening, which makes her realize how much he's really hurting.
Well, it could be that she broke some important rule or did something that really angered another character, and they decided to send a howler to give her a piece of their mind. Or perhaps it was a misunderstanding that led to the howler being sent to her.
Harry would also be very protective of Hermione. He would likely step in between Molly and Hermione, using his status as the Boy Who Lived if necessary to defuse the situation. He might try to reason with Molly, reminding her of all the good things Hermione has done for them and for the wizarding world.
If Molly blames Harry, it could lead to a rift. Harry respects Molly a great deal, so her blame might make him question his place in the Weasley family. On the other hand, Molly might start to see Harry in a more negative light and be less warm towards him. This could also affect how the other Weasley family members interact with Harry. They might be caught in the middle between Molly's feelings and their own friendship with Harry.
Some fans might be put off by it. If they are fans of both Harry and Molly as characters, seeing Harry hating Molly in a fanfiction could be jarring and make them less likely to engage with that particular piece of fan work.
Well, 'Molly's Game' is based on the true story. It takes the real - life events and dramatizes them. In the movie, some events might be tweaked a bit for cinematic effect, but overall it captures the essence of Molly Bloom's experiences running high - stakes poker games.
In some fanfictions, Harry's scar might hurt because of dark magic remnants. Maybe there are leftover spells from Voldemort that still linger and cause pain. It could also be a sign of a new threat emerging, like a hidden follower of Voldemort trying to use dark magic in a new way that affects Harry through his scar.
Maybe she's trying to scold him for something he did wrong or to give him a stern warning.
It could be that Molly crossed a line with Harry, and he felt that a howler was the only way to get his point across and make her understand his perspective. Maybe it was a big misunderstanding or a serious rule violation on Molly's part that triggered Harry's reaction.
The relationship could develop through communication. If Molly tries to control Harry, they could have some heart - to - heart talks. Harry could express his feelings about being controlled, and Molly could explain her motives.
The next generation often sees fanfiction as an extension of the books they love. They view it as a way to explore different 'what - if' scenarios with the characters and settings from the original books.
