In certain fanfictions, Harry's fall could be a part of a larger conspiracy. Maybe someone tampered with his broom on purpose. This would then lead to an investigation, with Harry and his friends trying to figure out who was behind it. Along the way, they could uncover other secrets about Hogwarts or the wizarding world in general, which would add more depth and complexity to the plot.
He could get seriously injured. In some fanfictions, he might break a bone or two. It would also likely lead to him being out of the Quidditch match if it happened during one.
In some fanfictions, his fall off the broom could be a turning point in the story. It might lead to him discovering a new magical ability. For instance, he could unconsciously use a form of magic to slow his fall or even levitate himself slightly. This newfound ability could then be explored further in the story, perhaps making him a more powerful wizard in unexpected ways.
Dumbledore could also be a savior. Given his powerful magic, he could easily appear at the scene and use a spell to stop Harry from hitting the ground too hard. Or perhaps one of the teachers at Hogwarts, like Professor McGonagall, who is strict but caring, would use her transfiguration skills to create something to break his fall.
In fanfiction, once Harry Potter falls through the veil, the plot could take many directions. One possibility is that he discovers a conspiracy that led to his fall. He might then have to team up with some unlikely characters to expose the truth. Another direction could be that he has to adapt to a world where time moves differently, and he has to race against time to get back to his own world before it's too late.
First, Harry would have to adjust to the new environment. He'd be surrounded by technology he doesn't understand. As the story progresses, he'd learn about Stark's world and how things work. Stark, on the other hand, would be curious about Harry's magic. They'd start collaborating, perhaps on a project to create a device that can detect magic. Along the way, they'd face challenges, both from those who fear magic and those who want to steal Stark's technology. Their friendship would grow as they overcome these obstacles together.
A plot twist could be that when Draco falls off his broom, instead of Hermione helping him directly, she uses a spell to make his broom catch him at the last moment. This shows her intelligence and also makes Draco question her motives. Later, he discovers that she didn't want to expose their growing friendship to others. Another twist could be that Draco's fall was actually a planned thing by someone who wanted to harm him, and Hermione has to figure out who it was while taking care of Draco. This adds a mystery element to the story.
Often, the plot develops with a sense of mystery. His friends would start to investigate what really happened to get him sent there. There would be a search for evidence to prove his innocence. Meanwhile, Harry in Azkaban might discover some dark secrets about the prison itself or about those who sent him there.
When Harry Potter refuses detention in fanfiction, the plot may develop in a way that Harry starts to question the entire Hogwarts disciplinary system. He could form a group of like - minded students who also have issues with the way detentions are given. This group might then try to change the system from within. Meanwhile, the faculty would be in an uproar, with some teachers seeing Harry as a troublemaker and others perhaps secretly admiring his courage. The story could then focus on the power struggle between the students and the teachers over the detention system.
Well, typically, the storyline begins with a shift in their relationship dynamic. Harry, who has been somewhat oblivious to Ginny's charm in the early parts, suddenly sees her in a new light. This could be triggered by an event, like Ginny performing a particularly impressive bit of magic. From there, they start to spend more time together, and their relationship blossoms. As the story unfolds, they may face external threats that test their love. These could be dark wizards or even political unrest in the wizarding world. Through these trials, their love for each other deepens, and they become an important part of each other's lives.
