A great Hermione stands up to Mrs Weasley fanfiction would incorporate the magical world's backdrop well. It could be set during a big family gathering at the Burrow. Hermione might stand up because of a difference in opinion about how to handle a magical creature situation. The author should also explore the emotions of both characters - Hermione's determination and Mrs Weasley's shock or disappointment, and how they resolve those feelings.
I'm not sure of the exact title, but there are some fanfictions where Hermione stands up to Mrs Weasley regarding Ron. It explores how Hermione won't let Mrs Weasley interfere too much in their relationship, showing Hermione as a confident and assertive character.
One scenario could be when Molly tries to interfere in Hermione's relationship with Ron. Hermione might stand up and say that she and Ron will figure things out on their own terms, not according to Molly's old - fashioned ideas. For example, if Molly tries to push for a quick wedding, Hermione could firmly state that they are focused on their careers and personal growth first.
Maybe Hermione made a decision regarding Ron that Mrs Weasley didn't approve of. For example, if she rejected Ron's marriage proposal in a rather harsh way, Mrs Weasley, who was very fond of Hermione as a potential daughter - in - law, could be extremely disappointed and angry.
It could also be related to a boy. If both Ginny and Hermione are interested in the same guy, say Harry Potter, Hermione might stand up to Ginny to assert her own feelings or to clarify some misunderstandings that Ginny has about her relationship with the boy. This can create a tense situation between them in the fanfiction.
Hermione could be very hurt. She respects Mrs Weasley a great deal, and to receive such an angry message from her would be a big blow. So she might cry and isolate herself for a while to think about what she did wrong and how to make it right.
She could develop better conflict - resolution skills. As she stands up to Ginny, she has to deal with the consequences and find ways to resolve the issues that arise. This may involve learning to listen to Ginny's side as well, which would make her more empathetic and better at handling disagreements in general.
A really interesting fanfic is 'Hermione Against Draco'. In this one, Hermione stands up to Draco during a Potions class. He tries to undermine her skills, but she shows him that she's just as good if not better. There's also 'Facing Draco' where Hermione faces Draco's attempts to get her in trouble with Snape. And 'Hermione's Courage' shows her standing up to Draco's group of Slytherin cronies when they try to corner her in a corridor.
A great fanfic could be where Hermione stands up for Snape when some other characters are gossiping about his past as a Death Eater. She might argue that people should be judged by their present actions and not be condemned forever for past mistakes. She could point out how Snape has risked his life countless times to protect the students at Hogwarts, like when he tried to keep the Death Eaters at bay during the school's attacks. This shows that Hermione recognizes his true worth and is not afraid to go against the popular opinion to defend him.
One great 'Harry stands up for Hermione fanfiction' is 'The Protector'. In this story, Harry defends Hermione against a group of Slytherins who are spreading false rumors about her. It shows their strong friendship and Harry's loyalty.
One key moment could be in the potions class. Snape might be unfairly criticizing Hermione's potion - making skills, and she just refuses to take it silently and stands up to him, stating her case clearly. Another moment might be when Snape is being overly harsh on one of her friends, and Hermione steps in, protecting her friend and facing Snape's wrath head - on.
