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.
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.
One reason could be that they played a particularly mischievous prank on her that went too far. For example, if they made her late for an important exam or meeting with a professor by using one of their wild magical inventions. Hermione, being a stickler for rules and academic achievement, might lose her temper and hex them in retaliation.

Well, it's a wild fanfiction concept. Fanfic writers might play with the idea by having some sort of magical mix - up or a different relationship path for Hermione. Maybe there's a spell gone wrong that leads to this unexpected pregnancy. But it would surely be a huge departure from the original story's themes and relationships.
I'm not sure if there is a specific fanfiction exactly with that title. However, in the vast world of fanfiction, there could be many stories exploring different relationships and scenarios. You can try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own using relevant keywords to see if such a story exists.
