Hermione is threatened with expulsion fanfiction: How might Hermione react to this threat?

Perhaps it's because she was involved in a secret society that the school authorities disapproved of. In many fanfictions, there are underground groups that Hermione might join in an attempt to fight against some emerging evil. But the school, not fully understanding the situation, could see this as a threat to the order of the school and thus threaten her with expulsion. Or, she might have been experimenting with new and untested magic that the school deemed too dangerous. This is not uncommon in the wizarding world where innovation can sometimes be seen as a threat.

Another reaction could be that Hermione becomes a bit rebellious. If she feels the punishment is too harsh or unfair, she might start to secretly oppose the headmaster's rule. This could lead to a series of events where she tries to find loopholes in the school rules or even starts a small movement among the students to question the headmaster's decision - making.

She might be initially confused. After all, Draco is usually her adversary. She could be very suspicious and start to investigate what exactly in the potion is causing this strange phenomenon.

Hermione may first try to use magic to defend herself or escape right when the kidnapping is taking place. But if that fails, she will start to analyze the situation. She would think about what she knows of Dolohov from her studies and any previous encounters. Then, she would form a plan. She might even try to find allies within Dolohov's ranks if there are any who could be swayed, by appealing to their sense of self - preservation or better nature.

She would probably be very angry. Hermione is known for her strong will and intelligence. Being restrained against her will would likely make her furious and she'd start shouting at Fleur, demanding an explanation.

She would probably be very indignant. Hermione is known for her strong sense of justice, so she would likely demand an explanation and try to prove her innocence.

Hermione could react by using her intelligence to expose Fleur's betrayal. She might start gathering evidence of what Fleur has done wrong and present it to their mutual friends or to an authority figure in the wizarding world.

Often, Hermione reacts with a mix of shock and anger. She's a strong - willed character, so she doesn't just take it lying down. In some fanfictions, she immediately confronts the cheater and gives them a piece of her mind.

Hermione would probably be defiant at first. She's not one to take injustice lying down.

Hermione could become withdrawn. She might isolate herself from her friends for a while, spending her time in the library trying to make sense of it all. She might also feel a sense of betrayal, especially if they had some sort of understanding or relationship developing.
