Firstly, Fred would be worried sick because Hermione is not only a friend but also an important part of their Hogwarts community. He'd probably call for help from the teachers or other students who are good at healing. Meanwhile, Hermione herself might be in shock. She could be thinking about how this happened and if it was an accident or a malicious act. If it was the latter, it could lead to a whole mystery that Fred and others would need to solve to ensure her safety in the future.
She might be in pain and cry out. Then she would try to assess her own injuries as she is a very intelligent witch.
Well, one possibility is that Hermione might be really surprised. She's always been more of a friend to the Weasley twins in a different way. She could initially be hesitant, thinking about her studies and how going to the ball with Fred might disrupt her routine. But then, she might see it as a chance to have some fun outside of her books. After all, the Yule Ball is a special event.
In fanfiction, Fred's worry about Hermione breaking her arm can be a catalyst for character growth. His worry forces him to face his feelings for Hermione. This internal struggle can add depth to the plot. He may also become more assertive in trying to keep Hermione safe, which could lead to conflicts with other characters who have different ideas about how to handle the situation. This can create a complex web of relationships and events that drive the story forward.
Well, they could catch up on old times. Maybe Fred would share all the wild pranks he's been up to since school. And Hermione would probably talk about her latest academic achievements. They might also rekindle old friendships with other classmates who are at the reunion.
One great fanfiction with this theme could be 'Hermione's Close Call' where Fred is constantly by Hermione's side after she has a near - arm - breaking accident during a Quidditch match gone wrong. It shows his concern in a really sweet way.
Fred could use his knowledge of the Weasley family's magic tricks and inventions. He might have some secret gadget or spell that can break through the barriers or spells that are being used to torture Hermione.
Well, one thing that could happen is that Hermione would be exposed to a whole new family dynamic. Sirius has his own wild past and rebellious nature. He might encourage Hermione to be more daring in her magic, perhaps showing her some spells that are a bit on the edgy side but still within the bounds of good magic. Also, she could learn a great deal about the Marauders from him directly, which would give her a new perspective on the history of Hogwarts.
She might discover new magical abilities that are unique to elves. For instance, elves are very good at household magic. Hermione could use these new skills to improve the living conditions in the Gryffindor common room. She could make the furniture more comfortable or keep the room cleaner without using much effort.
She could accidentally change other things in the past. For example, her presence might disrupt some other events that were supposed to happen. Maybe she prevents another character from getting a crucial piece of information, which then has a ripple effect on the future.
She might be used as a hostage to bargain with Harry Potter and his friends. The Death Eaters could try to extract information from her about the Order of the Phoenix.
