It could be that Fleur has been brainwashed by a powerful wizard who wants to use Harry for some evil purpose. Fleur kidnaps Harry and takes him to a magically sealed cave. As Harry is trapped there, he tries to use his magic to communicate with his friends outside. Meanwhile, Fleur starts to regain her senses little by little and realizes the wrong she has done. She then has to decide whether to help Harry escape or continue to follow the orders of the wizard who brainwashed her.
One possible plot could be that Fleur has been influenced by some dark magic or a powerful enemy. Maybe she's being blackmailed to kidnap Harry. She might take him to a hidden location, perhaps an old, abandoned castle. Then, the story could revolve around Harry trying to figure out why Fleur did this and how to escape while also dealing with Fleur's internal struggle about what she's done.
Maybe Fleur has some ulterior motive. She could be under the influence of a dark wizard who forces her to kidnap Harry. Or perhaps she believes Harry has something she needs desperately, like a powerful magical item that she thinks can save her family or something.
At first, Harry would likely be shocked and angry. He's used to being in dangerous situations, but being kidnapped by Fleur, someone he thought was an ally, would be a big betrayal. He'd probably try to fight back immediately, using his magic if he could.
It could be that they leave to attend a special magical training that is only available in a very secluded place. They might have received an invitation from a very powerful and reclusive wizard. This training could enhance their magical abilities in ways that Hogwarts or Beauxbatons couldn't. They see this as an opportunity to become stronger and more self - reliant, so they leave together, excited for the new challenges and knowledge that awaits them.
It could be that Lucius is under the orders of Voldemort. Voldemort wants Harry alive but in his control, so he sends Lucius to kidnap Harry. Lucius might then keep Harry in some secret location, perhaps an old Malfoy manor cellar, guarded by dark magic spells. Harry would then have to find a way to escape, maybe by using his own unique magic abilities or with the help of his friends who eventually figure out where he is.
Yes, there might be such fanfics out there. Fanfic writers often come up with all sorts of creative and sometimes out - of - the - box scenarios. You can try searching on popular fanfic websites like Fanfiction.net or Archive of Our Own. Just type in the title keywords and see what pops up.
One possible plot could be that they meet secretly in the Forbidden Forest. Fleur might be drawn to Harry's courage and Harry could be intrigued by Fleur's beauty and unique charm. They start sharing their secrets, like Harry telling Fleur about his struggles with Voldemort that he doesn't share with others. Their relationship grows as they find solace in each other's company away from the prying eyes of Hogwarts and the wizarding world.
Perhaps in the fanfiction, there is some sort of magic gone wrong. Harry and Fleur are caught in a magical spell that makes them act out of character. This leads to their relationship becoming more intimate than expected and Fleur getting pregnant. The rest of the story might be about them trying to reverse the spell while also coming to terms with the pregnancy.
One possible plot could be that Harry and Fleur's pregnancy is a result of a magical accident during a joint mission. They initially struggle with the news, as they have different worlds and cultures. Harry is from the wizarding world of Britain and Fleur is from France. But as the pregnancy progresses, they start to discover new things about each other and their respective heritages, and they come together to prepare for the arrival of their child. They might face opposition from some quarters who think their union is strange, but they overcome all odds with their love for each other and the future of their family.
Well, perhaps they run away because of a misunderstanding within the wizarding community. Harry and Fleur might have been wrongly accused of something, like stealing a powerful magical artifact. So they decide to flee and clear their names on their own terms. They journey through different magical lands, encountering various magical creatures along the way that either help or hinder them.
Well, it could be a really strange and magical plot. Maybe Harry has some sort of time - travel or magical transformation that makes him Fleur's mother in an alternate reality. It could involve a lot of confusion as characters try to understand this new relationship dynamic.
