What are the most interesting plotlines in Hermione and Fleur Triwizard Tournament fanfiction?

There are fanfictions where Hermione and Fleur become friends during the Triwizard Tournament. In some stories, they start to see past their initial rivalries. Fleur might initially see Hermione as just a book - smart girl, but as they face the challenges of the tournament together, they develop a mutual respect. Maybe they work together on the Yule Ball preparations within the context of the tournament, which helps to strengthen their bond.

One common plotline is that Hermione participates in the Triwizard Tournament instead of Cedric. This gives her and Harry a whole new dynamic as they face the challenges together. Another plotline could be that there's some sort of magical interference during the Tournament that makes Harry and Hermione realize their deeper feelings for each other. For example, a spell gone wrong that makes them share their innermost thoughts.

One possible scenario in this fanfiction could be that Harry and Fleur form an unexpected alliance during the Triwizard Tournament tasks. They might discover they have complementary skills, like Harry's courage and Fleur's elegance and magic related to water (since she's from Beauxbatons). This alliance could lead to them facing the challenges in a new and interesting way, perhaps with Fleur using her Veela charm in a creative manner to distract the obstacles while Harry uses his Gryffindor bravery to take on the more physical parts of the tasks.

A really cool plotline could be that the Triwizard Tournament tasks are all connected to an ancient prophecy that only Harry and Susan can figure out. They start to notice strange symbols during the tasks that lead them on a hunt through Hogwarts' secret passages to uncover the truth behind the prophecy.

Maybe in the fanfiction, there's a plot twist where Hermione discovers a hidden rule in the Triwizard Tournament that allows her to form an alliance with all the champions instead of competing against them. This would change the whole dynamic of the tournament and lead to a completely different kind of story.

There could be a plot point where Fleur's Veela heritage causes problems during the tournament. For example, it might attract unwanted attention from some of the creatures in the tasks, like the dragons in the first task. Harry has to use his quick thinking to protect Fleur and keep her focused on the task at hand. This could lead to some comical as well as intense situations as they try to deal with the chaos caused by her Veela charm.

Perhaps in the fanfiction, Fleur could be in danger during one of the Triwizard Tournament tasks. Harry, being the heroic type, decides to risk everything to save her. This act of heroism not only changes their relationship but also how the other champions and the judges view Harry. It could also lead to some changes in the overall dynamic of the tournament, like new rules being implemented to prevent such dangerous situations in the future.

One possible fanfiction could be about Harry and Hermione teaming up secretly during the Triwizard Tournament tasks. They might use their combined knowledge and skills to outwit the other competitors. For example, in the maze task, they could have a special code to communicate and find their way to the Triwizard Cup faster than anyone else.

One interesting plotline could be Hermione facing unique challenges as a champion that are different from what Harry faced in the original Triwizard Tournament. For example, she might use her extensive knowledge in unexpected ways to overcome tasks. Another could be how her relationships with Ron and Harry are affected. Ron might initially be jealous but then come to support her wholeheartedly. And she could also form new alliances with students from other schools in the process of the tournament.

A plot twist could be that the Triwizard Cup is actually a portal to a different dimension, and Harry and Hermione accidentally get transported there during the final task. They then have to find a way back while dealing with strange creatures and magic in this new dimension.
