Ron would probably be horrified. He loves Hermione deeply, and his mother has always been an important figure in his life. He would be caught in a really difficult situation. He'd likely try to stop his mother immediately and protect Hermione.
One possible motive could be jealousy. Maybe Molly is jealous of Hermione's close relationship with her son Ron. Another could be that she feels Hermione is a bad influence on the family in some way, perhaps her non - pure - blood status makes Molly, who has some traditional views, act out. Or it could be a misunderstanding, like Hermione being wrongly accused of something that makes Molly think she's a threat to the family.
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.
One possible reason could be jealousy. Maybe Molly is jealous of Hermione's intelligence and the special bond she has with Harry and Ron. Another reason might be that she feels Hermione is a bad influence on her sons in some way. For example, she might think Hermione's Muggle - born status could bring trouble to the family in the wizarding world which is full of pure - blood supremacist ideas.
Well, in some fanfictions, it might be because of a misunderstanding. Maybe Hermione's actions are misinterpreted by Molly. For example, if Hermione is too focused on her studies or magic research and seems to neglect the family values that Molly holds dear, Molly could start to dislike her. Another reason could be that Molly is overprotective of her son Ron, and she might think Hermione is too pushy or controlling in their relationship.
In some fanfictions, Hermione might please Molly Weasley by showing great respect for the Weasley family traditions. For example, she could participate wholeheartedly in the preparation of family feasts, using her intelligence to follow Molly's recipes precisely. She might also use her magic skills to help around the Burrow, mending things or cleaning in a way that Molly appreciates.
I'm not sure if there is a specific fanfiction with that exact title. However, fanfiction websites like FanFiction.net and Archive of Our Own have a vast collection of Harry Potter fanfictions. You could try searching for key words related to Molly Weasley, Hermione, and any relevant themes there.
She may also use her quick thinking and intelligence. For instance, she could try to reason with Tonks, appealing to their shared values or common friends in the wizarding community. If Tonks is acting out of a misunderstanding, Hermione could talk her out of it by presenting facts and explanations. Hermione is known for her logical thinking, and this could be a powerful defense tool.
In some fanfiction, this can be a rather unique theme. However, it's not overly common as Hermione is often paired with other characters in more traditional fanfic scenarios. But there are always out - of - the - box ideas in fanfiction. Writers might explore this concept to add a new twist to the story, showing a different side of Hermione's character or creating an unexpected relationship dynamic.
Hermione might run away crying. This would be a common reaction as she is a sensitive person. She could then go to Harry for support, and they might come up with a plan to resolve the issue with Molly.
