How would the friendship between Harry and Draco in 'Harry and Draco friends before Hogwarts' fanfiction affect their relationship at Hogwarts?

One possible plot could be that they meet at a wizarding event in their early childhood. Maybe their families are both attending a magical fair, and the two boys, not yet influenced by the future rivalries at Hogwarts, strike up a friendship over their shared love for magical creatures. They might spend the day together looking at baby unicorns and discussing their favorite magical beasts.

At first, they would avoid each other as much as possible. But when they are forced to collaborate on something important, like planning a big event at Hogwarts, they begin to communicate. They argue a lot in the beginning, but then they realize that they have more in common than they thought. They both care about Hogwarts and its future, and this common ground could be the foundation for a better relationship.

At first, their relationship might be full of confusion. They've been brought up with different values - Harry with his Gryffindor courage and sense of justice, and Draco with Slytherin pride and ambition. But as they discover they're twins, they'd start to see the similarities in themselves. They might begin by being a bit hostile towards each other, but gradually, as they face challenges together, like dealing with a particularly tough teacher or a dangerous creature on the grounds, they'd form a bond.

If Harry were Draco's older brother in this fanfiction, their relationship at Hogwarts would be a total mess - up of the original dynamic. Harry would be constantly torn between the Gryffindor values he adheres to and his family bond with Draco. Draco might start to question his Slytherin - only ideology because of his connection to Harry. For example, they might find themselves in situations where they have to choose between their house loyalties and their new - found brotherly bond, like during the Quidditch matches or the Triwizard Tournament.

It could make Draco feel exposed and vulnerable at first. But if Hogwarts uses the knowledge from his memories to help him, Draco might develop a newfound respect and loyalty towards Hogwarts. He could see it as an entity that truly cares about him rather than just a place of learning.

Well, their friendship could start with a common goal. Maybe they find out about a hidden danger in Hogwarts that the teachers are unaware of. Harry's bravery, Hermione's intelligence and Draco's knowledge of the Slytherin side of things could combine to solve the mystery. They might initially be reluctant to work together, but as they face challenges, they start to respect each other more and form a real friendship.

They could form a sort of alliance. Harry, being the hero figure, could bring Draco into his circle of friends more often. Draco, with his Slytherin knowledge and connections, could help Harry in understanding some of the more mysterious aspects of Hogwarts, like the secrets of the Slytherin common room. Their relationship could bridge the gap between Gryffindor and Slytherin, changing the whole dynamic of the houses at Hogwarts.

Their relationship could change Hogwarts in many ways. For one, they might form an alliance against common enemies within the school, like bullies or those who promote pure - blood supremacy too aggressively. This could lead to a more united front among the students. Also, their friendship (if it develops) could influence house rivalries. Gryffindor and Slytherin might not be as divided as before. Students might start to see that there are good people in both houses and that family bonds can transcend house differences.

In Hogwarts, it would be a wild change. Draco would be super conflicted. He's been taught to look down on Gryffindors and half - bloods like Harry. But with Harry as his brother, he'd have this internal struggle. Harry would probably be more open to Draco than Draco is to him. Harry would hope to convert Draco to a more accepting way of thinking. There would be times when Draco would be mean to Harry in public to keep up appearances, but in private, he might start to question his own beliefs because of their relationship.

When Draco turns Harry into a vampire, it throws his friendships into chaos. His friends are used to the regular Harry, the one who battles Voldemort and plays Quidditch. Now, he has different needs and behaviors. Some friends may distance themselves out of fear. But others, like Neville, might be curious and try to help him adjust. His relationship with Ginny would also be tested as he has to deal with his new vampire nature and how it affects their relationship.
