Yes, there might be. Fanfiction websites like FanFiction.net or Archive of Our Own could potentially have such stories. However, the availability can vary depending on the creativity of the fanfiction writers in the Harry Potter fandom.
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.
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.
Hermione could be involved. She might suspect Daphne of having ulterior motives regarding Harry and try to warn him, which could play into the betrayal storyline in some way, either as a catalyst or as someone who helps Harry deal with the betrayal later.
The 'Harry and Daphne Obliviate' fanfiction concept is really cool. When Obliviate is involved, it can explore themes of power and responsibility. Harry, having experienced the misuse of powerful magic, should be more cautious. But if he uses Obliviate on Daphne, it might be out of good intentions like protecting her from a dark secret. However, Daphne might feel violated when she realizes her memories have been tampered with, which can lead to conflict between them and drive the plot forward in many different ways.
Yes, in some fanfictions Daphne can be Harry's mate. Writers often create alternative pairings in fanfiction, and Daphne is a character that some authors choose to pair with Harry for various reasons, like creating new storylines or exploring different character dynamics.
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.
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 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.
