At first, there would be a lot of confusion. Harry would be trying to figure out Draco's motives for saving him. Draco would be dealing with the fact that he actually saved Harry Potter. Over time, they could develop a sort of friendship. They might start sharing secrets, like Draco telling Harry about some of the things that go on in Slytherin house, and Harry sharing his own fears and hopes about the future of the wizarding world. This new - found relationship would be a big shock to their friends on both sides.
The relationship change could be quite complex. Harry might feel indebted to Draco, which could make Draco feel a bit superior at first. But as they interact more, they realize they have more in common than they thought. They could start working together on some small projects in Hogwarts, like helping to improve the school's security against dark magic. Their relationship could go from one of enmity to a partnership of sorts, where they each use their strengths (Harry's courage and Draco's cunning) to achieve common goals.
Their relationship could become more of a grudging respect. Harry would be grateful to Draco for saving his life, but still a bit wary because of their past. Draco, on the other hand, might start to see Harry in a new light, not just as the 'Chosen One' he used to envy and dislike. They might start to interact more civilly, like nodding to each other in the corridors instead of glaring.
It often changes for the better. After Harry apologizes, Draco might be initially skeptical. But as they start to interact more, they could become friends or at least develop a mutual respect. For instance, they might start sharing their experiences during the war, which helps them understand each other better.
At first, it would become more strained. Harry would likely be angry and hurt by Draco's actions that made him cry, so he might avoid Draco even more than before. He might also be more on guard around Draco, not trusting him at all.
Their relationship would likely become more collaborative. They would have to communicate regularly about Teddy's needs, like his schoolwork, his magical training, and his emotional well - being. This would force them to put aside their past grudges and start seeing each other in a new light.
When Voldemort attacked Hogwarts, Harry, Ron, and Hermione went to the Room of Requirement to find Ravenclaw's diadem. Crabbe tried to kill Harry and set the entire Room of Requirement on fire with Dark Magic Fire. Before Harry escaped, he saw Draco struggling in the fire and rescued him because he could not bear to see him die here. Later, in the Forbidden Forest, Draco's mother, Narcissa, deceived Voldemort to save Draco and secretly saved Harry. This also indirectly resolved the contradiction between Harry and Draco. Harry Potter and the Order of the Phoenix is not enough. Please click to read the novel!
Well, it would likely make their relationship much more complex. Instead of the typical rivalry, there could be a sense of family obligation. Draco might feel protective of 'her' in a different way than he would a male Harry. He might be torn between his family's views and this new connection to Harry.
They would probably become like brothers. With Snape as their common father figure, they would have to learn to get along. Harry might be more forgiving of Draco's past actions, and Draco would have to let go of his animosity towards Harry.
Their relationship can become one of mutual respect. Harry's niceness shows Draco that there is more to life than pure - blood supremacy. Draco, in turn, might start to respect Harry for his open - mindedness. This can be seen in fanfictions where Draco begins to support Harry's causes, like improving relations between different houses at Hogwarts. Their relationship evolves from one of enmity to one of respect and cooperation, all because of Harry's initial niceness.
It could change in a more positive way. In detention, they might have to rely on each other to get through Snape's tasks. If they are made to work on a complex magical experiment, they would need to communicate. This communication could break down some of the barriers between them. Maybe they start to exchange a few friendly words outside of detention, slowly building a more amicable relationship.
Well, in these fanfictions, their relationship undergoes a significant transformation. It begins with confusion and resistance. Harry is used to seeing Draco as an adversary, and Draco has his own pride as a Slytherin. But as they explore their newfound brotherhood, they learn to respect each other's differences. Draco's refined knowledge of magic and wizarding traditions can be an asset to Harry, and Harry's ability to inspire loyalty in others can be beneficial to Draco. They start to collaborate, whether it's in their studies at Hogwarts or in facing bigger threats outside the school. Their relationship becomes one of mutual growth and understanding, evolving from hatred or at least strong dislike to a deep, brotherly bond.
Their relationship would likely become more collaborative. They would have to put aside their past differences for the sake of their son. Instead of being rivals, they would become partners in parenting. They would need to communicate more often about their son's upbringing, which would force them to get to know each other better on a personal level.
