They would likely become closer. Having a baby is a big responsibility, and they would need to rely on each other more. Their relationship might shift from a more romantic and carefree one to a more mature and partnership - based one, focused on the well - being of their child.
Well, at first, they might face some stress - related changes. But as time goes on, they would grow stronger together. Harry, who has always been a bit of a loner at times, would now have a family to truly belong to. Daphne, on the other hand, might become more nurturing and less of the aloof Slytherin she was before. Their love for the baby would bind them even more tightly.
Well, before the pregnancy, they might have had a more carefree relationship. But once Daphne gets pregnant, it would be a turning point. Harry would become more protective of Daphne, and Daphne would start to see Harry in a new light, as a potential father. There would be a deeper level of intimacy as they share the experience of bringing new life into the world. They would also have to communicate more openly about their fears, hopes, and plans for the future.
It could develop into a strong friendship. Since they meet as babies, they grow up with a sense of familiarity. They might trust each other more than others and always be there for one another.
The relationship could develop through shared interests. Say they both have a passion for ancient magic. They start discussing it in the library, and as they do, they find themselves drawn to each other more and more. Their conversations grow deeper, and before long, they realize they're in love. Harry might share his experiences with Voldemort with Daphne, and Daphne could open up about her family's expectations. This mutual sharing of personal and difficult things would strengthen their bond.
In some fanfictions, their relationship develops through shared secrets. Daphne might share some Slytherin secrets with Harry, and in return, Harry tells her about his experiences with Voldemort. This sharing of personal and important information brings them closer together. They start to rely on each other more and more, and eventually, their relationship can range from a deep friendship to a romantic one, depending on the direction of the fanfiction.
The relationship could also develop through cultural exchange. Daphne, being from a pure - blood Slytherin family, has different values and traditions compared to Harry. As they get to know each other, they introduce their respective cultures to one another. This leads to a deeper understanding and a more profound emotional connection between them.
Their relationship could be one of mutual protection. Harry, with his heroic nature, would always be ready to defend Daphne. And Daphne, being intelligent and resourceful, could offer her own kind of support to Harry, like helping him with his studies or providing advice in tricky situations.
In the fanfiction, their relationship could develop in a rather unexpected way. Since they live together, they are constantly in each other's presence. Harry might start to teach Daphne some of his Quidditch moves in the backyard, and Daphne could introduce Harry to some of the more sophisticated Slytherin social etiquette. As they engage in these activities together, they start to respect and admire each other more. Eventually, this could lead to a romantic relationship or a very deep friendship depending on how the author wants to take the story.
The dynamic would change in several ways. First, in the classrooms, they might work together on projects more often, which could lead to better grades for both of them. Their friendship could also influence the Quidditch matches. Maybe Daphne would convince some of the Slytherin students to not be as rough during the matches against Gryffindor. Also, in social events, their combined presence could break the ice between Slytherins and Gryffindors, creating a more inclusive and friendly environment at Hogwarts.
Their relationship could lead to more unity in the wizarding world. Since Harry is a well - known figure and Daphne is from a Slytherin family, their friendship might break down some of the traditional barriers between Gryffindor and Slytherin. It could inspire other students to look beyond house rivalries and work together for the greater good.
They could become study partners. Since they meet on the train, they might realize they can help each other out in different subjects at Hogwarts.
