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, in some versions, Fred might use his quick-witted magic skills. He could cast a distraction spell to draw Bellatrix's attention away from Hermione. Maybe a spell that creates multiple illusions of himself, confusing Bellatrix long enough for him to grab Hermione and disapparate them to safety.
Perhaps by having strong friendships come into play. If the story shows that Fred or other friends are desperately trying to save Hermione, it gives the reader hope. Like, Fred could be rallying the other Weasleys and Hogwarts students to find a way to rescue her from the torturous situation.
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.
Another theme is bravery. Fred and George have to be brave to face whatever is threatening Hermione. In some fanfics, they might have to go against powerful dark forces, and their courage is what enables them to succeed in the rescue.
One popular fanfiction with this plot is 'Time's Redemption'. In it, Hermione uses a powerful time - turning device to go back. She faces many challenges in the past, like avoiding detection by other characters while trying to figure out how to prevent Fred's death. It's a great read for those who love emotional and action - packed stories.
One possible fanfiction could be where Fred and Hermione discover their Animagus forms together. Maybe they transform in the Forbidden Forest and have to rely on each other to get back to Hogwarts safely. Their forms could be something that represents their personalities, like Fred could be a fox, known for its cleverness and playfulness, and Hermione could be an owl, symbolizing wisdom.
She might be in pain and cry out. Then she would try to assess her own injuries as she is a very intelligent witch.
One popular 'Fred and George Save Hermione' fanfiction is 'The Twin's Rescue'. In this story, Fred and George use their unique magical inventions to rescue Hermione from a dangerous situation in the Forbidden Forest. It's full of action and their signature Weasley humor.
Fred's reaction could be a complex mix of emotions. On one hand, he might be overjoyed at the thought of having a child with Hermione. He may immediately start making plans for their future as a family. However, he could also be a bit worried. After all, having a baby is a big responsibility. But his natural optimism would likely shine through, and he'd assure Hermione that they can handle it together. He might also crack a few jokes to lighten the mood, saying something like 'Our baby will be the most mischievous one in Hogwarts before we know it!'
Hermione, on the other hand, could become more daring. She is already brave, but this situation could push her to take risks she normally wouldn't. She might be the one to suggest trying untested spells or taking paths that are less known in order to escape. As they run, she could learn to trust her instincts more and not just rely on book knowledge.
