Perhaps their pre - Hogwarts meeting was so strange or significant that it makes them curious about each other during their Hogwarts years. They might keep an eye on one another, trying to figure out if the other person remembers the encounter in the same way. This could lead to a slow - burning relationship where they gradually get to know each other better through these small, curious interactions at Hogwarts.
If there was a rivalry before Hogwarts, it could carry over and make their interactions at Hogwarts more tense. However, this could also lead to them pushing each other to be better. For example, in Quidditch, if Fleur is also a good flyer, Harry might strive to outperform her, which could improve his skills as a Seeker. And over time, this rivalry might turn into mutual respect.
If they meet before Hogwarts, they might already have a sense of loyalty towards each other. So when they get to Hogwarts, they could look out for one another. For example, in a dangerous situation like a run - in with a rogue magical creature, they would be more likely to help each other compared to if they were just acquaintances. This pre - Hogwarts meeting could also mean they have inside jokes or shared memories that make their Hogwarts years more enjoyable.
Their meeting could also mean that Fleur might be more protective of Harry at Hogwarts. Since she knew him before, she might feel a sense of responsibility. So, during the Tournament, she could offer him some tips or help in a more discreet way, which could change the dynamics of how the Tournament unfolds for Harry.
Well, one possibility is that they could form an early friendship. Maybe Fleur, with her Veela charm, would initially intimidate Harry, but then they find common ground in their magical abilities. For example, they might discover they both have an affinity for certain types of magic that are not common among their peers. This could lead to them sharing magical secrets and techniques before even reaching Hogwarts.
One possible plot could be that they meet during a wizarding event in France. Fleur, being from a French wizarding family, might be at a magical fair. Harry could be there with the Dursleys on a 'family' trip (forced by the Dursleys to go to France). They accidentally cross paths and Fleur, sensing Harry's unique magical aura, strikes up a conversation. This could be the start of an interesting pre - Hogwarts friendship.
It would cause great shock. Harry was seen as a symbol of hope even before he started at Hogwarts. His death could lead to increased fear among the wizarding community as they might think Voldemort or other dark forces are getting stronger. It could also lead to a decline in the morale of those fighting against the dark side.
If they were friends before Hogwarts, it could create a lot of internal conflict at Hogwarts. Draco might be torn between his new Slytherin friends who dislike Harry and his long - standing friendship with Harry. He might try to keep their friendship a secret, which could lead to misunderstandings between them.
One possible plot could be that they meet in a muggle library. Hermione is there researching magic in the guise of general knowledge books, and Harry stumbles upon her while looking for a quiet place to escape from the Dursleys. They start chatting about books, and Hermione is intrigued by Harry's strange yet endearing manner. They then realize they both have a connection to the magical world.
One possible plot could be that they meet in Diagon Alley. Maybe Harry is lost while shopping for his school supplies and Daphne helps him find his way. This could start a friendship where they exchange stories about their expectations for Hogwarts. It might also be a chance for Daphne to see Harry as more than just the famous Boy - Who - Lived, and for Harry to make a friend outside of the Weasleys and Hermione.
The discovery of the abuse might make Harry more empathetic towards other students who have had difficult pasts at Hogwarts. He could become a sort of advocate for those who are bullied or mistreated. Also, it could affect his relationship with his teachers. Some teachers, when they learn of his past abuse, might be more lenient or offer more support, which in turn helps him grow and develop at Hogwarts.
The story would be drastically different. Without Harry, there's no Boy - Who - Lived to be the main antagonist to Voldemort. Hogwarts might not be the safe haven it was in the original series. Voldemort could target the school more directly, and the students would live in constant fear.
