When Harry asks Daphne to the Yule Ball in fanfiction, it really depends on the writer's take. Some might write that Daphne turns him down flat because she has her own ideas about who she should go with or she doesn't like the idea of being in the spotlight with Harry. Others may have her accept and they end up having a magical time at the ball, dancing and chatting, and this could even lead to a new friendship or something more between them in the subsequent chapters of the fanfiction.
Well, in some fanfictions, Daphne might be really surprised. She could initially be hesitant because of the house differences (Harry being a Gryffindor and she being a Slytherin). But then she might accept because Harry is a Triwizard champion and it would be quite an honor.
In the fanfiction, Susan might be really surprised and happy. She could say yes right away. They might then start planning what to wear and how to make their time at the Yule Ball special.
Well, in some fanfictions, Pansy might initially be shocked. After all, Harry and Pansy are from different 'cliques' in Hogwarts. But she could accept. They might have an awkward but interesting time at the Yule Ball. Harry could learn more about the Slytherin side of things from Pansy, and Pansy could see a different side of Harry than she expected.
Well, perhaps Katie would be really surprised and excited. She might say yes right away. Then they could start planning what to wear. Harry might be a bit nervous about the whole thing, but also looking forward to having a great time at the Yule Ball with Katie.
In the 'Harry asks Ginny to the Yule Ball' fanfiction, it could be that Ginny is initially shocked when Harry asks her. She might have thought he would ask someone else. But after a moment of hesitation, she accepts. And later they have a great time at the ball, dancing and chatting with their friends, and this could be the start of a deeper relationship between them.
She could say yes. Maybe she's always secretly liked Harry and this is her chance to get to know him better.
One possibility is that Harry would be really flustered. He's not used to such direct attention from someone as beautiful as Fleur. He might initially be in shock and not know how to respond. Then he would probably think about how this would affect his relationship with his friends, especially Hermione and Ron. Maybe he'd worry about Ron getting jealous since Ron has a bit of a crush on Fleur.
Well, one possibility is that Harry would be completely shocked. He might initially think Draco is playing some sort of cruel joke on him. After all, they've been rivals for so long. But then, he could start to consider it seriously. Maybe he realizes that this could be a chance to bridge the gap between them. He might accept, which would cause a huge stir among their friends and classmates.
They could become friends. Harry, being the hero he is, might reach out to Daphne, who is a Slytherin. At the Yule Ball, they could share a dance and discover they have a mutual interest in magical history. This could lead to them spending more time together, studying in the library and sharing their different perspectives on various magical topics.
Well, perhaps in this fanfiction, Daphne has a secret mission at the Yule Ball. She's supposed to spy on Harry for some Slytherin plot. But as she gets closer to Harry during the ball, she starts to have second thoughts. Harry, on the other hand, is just looking for a nice evening after all the Triwizard Tournament stress. They end up having a long conversation during a slow dance and start to develop a friendship that could potentially turn into something more.
In fanfiction, they might share a magical dance. Viktor could introduce Harry to some of his Bulgarian traditions during the ball. Maybe they become good friends and have deep conversations about their different magical cultures.
