One possible plot development could be that Daphne constantly tries to keep Harry away from other potential romantic interests. For example, she might interfere when Harry is talking to Hermione or Ginny, creating some tense and awkward situations.
One way to make it more interesting is through the use of different settings. Instead of just the usual Hogwarts setting, take the characters on an adventure outside, like to a magical forest or an ancient wizarding ruin. Daphne's possessiveness could play out differently in these new and dangerous environments. For example, she might be more overprotective because of the unknown threats, or her possessiveness could lead to her making a mistake that endangers them both. This would add excitement and novelty to 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.
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.
One possible reason could be that Fleur sees Harry as a powerful and important figure. In the wizarding world, Harry is the famous Boy Who Lived. Fleur might be possessive because she wants to be associated with his fame and power. Also, his bravery and skills could be attractive to her, making her want to have him all to herself in the fanfiction world.
One reason could be that in the original series, they are very close friends. Hermione might be possessive in fanfiction because she's protective of Harry. She's seen all he's been through and wants to keep him safe from harm, both physical and emotional, and this overprotectiveness can come across as possessiveness.
In fanfiction, Snape's possessiveness of Harry can stem from multiple factors. Snape has a deep - seated emotional turmoil within him. His feelings towards Harry might be a mixture of his unrequited love for Lily, Harry's mother, and his own self - imposed mission to safeguard Harry. He may also be possessive because Harry is constantly in danger, and Snape feels that only he can truly protect Harry, which in the world of fanfiction is often exaggerated and translated into possessive behavior.
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.
