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.
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.
One possible scenario could be that Harry realizes he misjudged Draco all along. Maybe he discovers that Draco was acting out of fear or family pressure rather than pure malice. For example, Draco might have been forced to take on certain tasks by his Death Eater father, and Harry finally understands this and apologizes for always being so hostile towards him.
The relationship between Harry and Draco in this fanfiction would be greatly affected. Since Harry has a connection to Draco's mom, Harry could become more empathetic towards Draco. He may realize that Draco is not just the bully he once thought. Draco might struggle with the idea that Harry has this special connection to his mom. However, as the story unfolds, they could learn to communicate better. Harry could share insights about Draco's mom that Draco never knew, and this could bridge the gap between them, leading to a less hostile and more nuanced relationship.
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 lead to a complete transformation of their relationship. They might become allies, working together against common enemies. The act of giving the wand could be the catalyst for them to let go of past grudges and form a bond based on shared values and goals. This could involve them sharing secrets, protecting each other, and even becoming friends outside of the immediate conflict situation.
In these fanfictions, Harry may develop a more diplomatic side to his personality. Since Draco is from Slytherin and has a different way of thinking, Harry has to learn to negotiate and find middle ground. For Draco, his friendship with Harry can make him more empathetic. He might start to care about the well - being of others outside of his Slytherin clique, like the Gryffindors and other Hogwarts students, which is a big change from his initial self - centered attitude.
In this type of fanfiction, Harry can transform from a somewhat impulsive hero into a more calculating and thoughtful person. This is because he has to deal with Draco's Slytherin - like thinking. Draco, who was once a self - centered and sometimes cruel character, may grow into a more selfless individual. The marriage law forces them to be in close proximity, and they start to influence each other in positive ways. For instance, Harry might influence Draco to be more open - minded about Muggle - borns, and Draco might teach Harry how to better protect himself using Slytherin - inspired strategies.
