Fleur could be developed to be more vulnerable. In the original, she is very much the proud and confident champion. Fanfiction could explore her insecurities, especially in relation to the tournament. And Hermione could be the one to help her through those tough times, showing a different side of Fleur.
In some fanfictions, Hermione's character might be developed with more confidence in the Goblet of Fire setting. For example, she could be more assertive in dealing with the Triwizard Tournament chaos. Instead of just following the rules as she does in the original, she might take more risks to protect Harry. This could be because the author wants to show a bolder side of her, unconstrained by the typical Hogwarts order.
Well, in fanfiction, their relationship might develop more quickly. For example, instead of constantly bickering, they could start to respect each other earlier. Maybe a shared experience in the Forbidden Forest during the Goblet of Fire events makes them see each other in a new light.
In some fanfictions, Hermione might be more assertive in her relationship with Harry. For example, she could be the one who takes the lead in most of their adventures, rather than Harry. This shows her growing confidence and leadership skills that were perhaps not as emphasized in the original book.
Well, in some fanfictions, Harry's relationship with werewolves could be explored in a much deeper way. He might develop a more empathetic side towards them, especially if he meets a werewolf who is not as bloodthirsty as the ones he has encountered before. Hermione could be developed to be more of a risk - taker. When it comes to werewolves, she might be willing to put herself in more dangerous situations to study them or help them, which is different from her usually cautious self in the original series.
Well, their relationship could become more of a rivalry. Instead of being friends, they could compete with each other to solve the mysteries around the Goblet of Fire. Each trying to outwit the other in finding out who put Harry's name in the Goblet.
One interesting plotline could be Hermione and Fleur teaming up to solve a mystery within the Triwizard Tournament. They might use their combined intelligence and skills. For example, Hermione's vast knowledge of magic and Fleur's charm and unique magical abilities could be a great combination to figure out a dark plot against the champions.
In such fanfictions, Hermione as a Time Lady could have her character development centered around her newfound abilities related to time. For example, she may struggle with the ethical implications of time travel and changing events. This is different from the original Hermione who was mainly focused on the study and practice of magic within the Hogwarts framework. Her relationships might also change. She could be more distanced from her friends at first as she tries to understand and control her new powers.
In these fanfictions, Hermione could be more fearless in the face of werewolf - related danger. In the original, she was mainly focused on academic and general wizarding world problems. But here, she might be more hands - on with werewolf matters, using her intelligence to solve problems specific to the werewolf community. For example, she could be researching new spells to help werewolves control their transformations, which shows a different side of her problem - solving skills.
Often, you'll see original characters who are students from other schools. For example, there might be a really smart and mysterious student from Durmstrang who becomes friends or rivals with Hermione. They could have their own motives for being at Hogwarts during the Goblet of Fire events.
In the original book, there's no such instance of Harry going into shock in the same way. In fanfiction, it's often an added element for drama. So, in fanfiction, it might be caused by some new and unique circumstances that the author has created, like a secret spell cast by an unknown character.
