Well, it could be that Gilbert's invitation to Harry out is part of a bigger plan. Maybe Gilbert wants to get closer to Harry to learn more about his magical abilities. Or it could be a genuine romantic interest. Harry, on the other hand, might be worried about how others will react, especially his friends who might not understand his relationship with Gilbert.
In the fanfic, perhaps there will be a lot of blushing and nervousness from Harry. Maybe he's initially taken aback by Gilbert's forwardness. He might need some time to think about his feelings, as he has so much else going on in his life, like dealing with Voldemort and his Hogwarts studies.
One possibility is that the outing is filled with misadventures. They could end up in a place they didn't expect, like a hidden part of the Forbidden Forest. There, they might discover something new together, which could either strengthen their bond or make Harry more hesitant. And the way they interact during this outing, whether it's stilted conversation or easy banter, will set the tone for their future relationship in the fanfic.
Gilbert might be an original character created specifically for this fanfic. He could be a student at Hogwarts from the Fire Fleur house, which is likely a fictional house made up for the story. He may have unique magical abilities or a distinct personality that draws him to Harry.
One possible reason could be that Fleur sees Harry's courage. In the 'Golbery of Fire' events, Harry shows great bravery, and Fleur might be attracted to that. She herself is a confident and somewhat proud character, and a brave partner like Harry could be appealing to her.
Harry could be flattered. Fleur is considered very beautiful, and for her to show interest in him would boost his self - esteem. He might stammer out a response, something like 'I - I'm honored, Fleur.' while blushing furiously.
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.
Ginny asking Harry out could lead to a very interesting chain of events. It could cause some jealousy among other students who have a crush on either of them. Ron, for example, might be a bit taken aback at first but then come around to support his sister and best friend. As for their date, it could be something unique like a midnight stroll in the Forbidden Forest (with proper precautions of course), where they talk about their fears, hopes and dreams, deepening their connection.
Well, it could also go wrong. Maybe Hermione has always seen Harry as just a friend, and his asking her out makes things really uncomfortable between them. She might turn him down gently but then worry about how it will affect their friendship. Their other friends, like Ron, could also get involved, perhaps causing more chaos if he has his own unexpressed feelings for Hermione.
Well, one possibility is that Fleur could be really surprised at first. Maybe she'd initially be hesitant because she might have had other plans or expectations for the Yule Ball. But then, she could see Hermione's earnestness and decide to go with her. They could end up having a great time, dancing and chatting, and maybe even become closer friends through this experience.
Perhaps Fleur is there to give Harry an invitation. It could be for a special event in the wizarding community, like a ball or a gathering of some sort. This would then lead to Harry having to make a decision about whether to attend and what it might mean for his relationships with his friends and enemies at Hogwarts.
Well, perhaps Percy plans this elaborate scheme to ask Annabeth out. He might enlist the help of their friends, like Grover. Grover could set up a picnic in a beautiful meadow. Percy then shows up with a bouquet of Annabeth's favorite flowers and asks her out. She would be touched by the effort he put in and say yes. Then they start planning all the things they want to do together on their first official date.
One possible scenario could be that Hermione finally realizes her deep - seated feelings for Harry. In the fanfic, perhaps after a particularly dangerous adventure where they almost lost each other. She might approach Harry in a quiet moment, like in the Gryffindor common room late at night when most students are asleep. She could be a bit nervous but determined as she asks him out for a walk by the lake or a trip to Hogsmeade. This would be a huge moment for their relationship as it takes a more romantic turn.
