At first, they are enemies. Malfoy hates Harry because Harry is famous and Malfoy wants to be the top wizard at Hogwarts.
In some fanfictions, it starts with distrust. Harry sees Narcissa as part of the Malfoy family, which has been on the wrong side. But as the story progresses, they might find common ground, like protecting the wizarding world from a new threat. This makes them slowly build a reluctant partnership.
At first, Harry might be a bit annoyed by Dobby's antics. But as the story progresses in the fanfiction, he could notice Dobby's good intentions. Dobby's eagerness to serve and protect Harry could touch Harry's heart. Maybe Dobby saves Harry from a particularly dangerous situation that makes Harry see Dobby in a whole new light. Harry then starts to admire Dobby's tenacity. He may also be intrigued by Dobby's strange habits, like his obsession with odd - looking socks. This new - found admiration could lead to Harry becoming a big fan of Dobby.
His magical abilities might develop in a different way. The Malfoys could introduce him to different types of magic or magical artifacts. Maybe he'd learn more about the Dark Arts in a different context, not for evil purposes but just to understand it better. He could also become more skilled in areas like Occlumency earlier on, since the Malfoys might see it as an important skill to protect their family secrets. His relationship with his Gryffindor traits would be tested. He might still have his bravery, but it could be expressed in different ways, like standing up to the Malfoy family's wrongdoings.
Some fanfictions take a more creative approach. When they meet on the platform, there could be a magical interference that makes them see each other's memories or feelings. This would be a huge shock for both of them. Harry might see that Malfoy has his own fears and pressures, and Malfoy might understand Harry's sense of loneliness despite his popularity. This could completely change the dynamic between them, leading to a relationship full of mutual understanding and a new - found respect.
At first, it might start with curiosity. Harry is used to his wizarding world, and the Muggle is something new. They might meet by chance, like in a park or a coffee shop. Then, as they get to know each other, they start sharing their different worlds. Harry might show the Muggle some simple magic tricks, and the Muggle might introduce Harry to Muggle hobbies.
At first, it might be less hostile. Since they're in the same house, Draco might see Harry as someone he can influence or befriend. Harry, on the other hand, would be cautious but also curious. They could end up having a sort of begrudging respect for each other as they realize they both have complex personalities.
Well, the relationship could start with Harry's squinting as a sign of his initial wariness. But as the fanfiction progresses, it could lead to a more direct confrontation. Harry might corner Wormtail and force him to face his actions. This could either end in Wormtail's redemption if he decides to turn against Voldemort for real, or it could end in his complete downfall as Harry brings him to justice. In any case, Harry's squinting at the start is like the spark that sets off the development of their relationship in the fanfic.
It could start with a lot of animosity on Harry's part, but as he is trained, he might start to see Voldemort in a different light. Maybe he begins to understand Voldemort's motives, though not necessarily agreeing with them.
It could become very close and trusting. They'd know each other inside out and have a deep bond from childhood.
Well, in many such fanfictions, at first Harry might be in the dark about his relation to the master. As the story progresses, there could be moments of discovery. Maybe the master initially tries to keep it a secret, but then small clues start to surface. Harry could start to feel a strange connection, like a pull towards the master. Eventually, they might have a big confrontation or a heart - to - heart where the truth fully comes out.
