Maybe it's a situation where Harry and Ron are having an argument. In the heat of the moment, Harry loses control of his magic a bit and something happens to Ron's leg. For example, they might be arguing about Hermione, and Harry tries to use a non - harmful spell to prove his point but it misfires and breaks Ron's leg. Another possibility is that it's part of a more complex plot where an evil force is influencing Harry's actions without him realizing it at first, leading to Ron getting hurt.
Well, perhaps it could be an accident during a Quidditch match. Harry might accidentally hit Ron with his broomstick while chasing the Snitch, causing Ron's leg to break. It could also be due to a spell gone wrong in a chaotic situation at Hogwarts, like when they're being chased by some dark creatures and Harry's hasty spell rebounds and hits Ron's leg.
In the fanfiction, it could be that Harry is under the influence of a cursed object. This object makes him act out of character and during a training session in the Room of Requirement, he performs a dangerous move that ends up breaking Ron's leg. Or, it could be a plot where Harry is trying to protect Ron from a Death Eater attack but in the process, his hasty actions cause Ron to get injured with a broken leg.
The antagonist could be a cursed object. This object, which has some dark magic in it, might be found by Harry. And when he interacts with it, it starts to control his actions, leading to him breaking Ron's leg. So, in this case, the cursed object is the source of the trouble and can be considered as the antagonist in the fanfiction.
One possibility could be that Percy's friends rally around him. They might take turns helping him with daily tasks like getting to class or bringing him food. His accident could also lead to some self - discovery, as he has to deal with being immobile for a while.
Well, one possibility could be that it was an accident. Maybe Hermione was in a rush during a spell - casting practice session and accidentally knocked Harry's wand out of his hand and it broke on a hard surface. Another could be that she was under the influence of some dark magic or a spell that made her lose control and break it in a fit of rage or confusion.
Perhaps Tonks starts dating someone else, like Remus Lupin. Harry has some unspoken feelings for Tonks, and seeing her with Lupin makes him feel heartbroken. In the fanfiction, it could show Harry's internal struggle to accept the situation and his pain at seeing the woman he cares about with another man.
One possible plot could be that Snape reveals some long - held secret about Harry's parents in a very cruel way. For example, he might tell Harry that his father was not as heroic as he thought, and this shatters Harry's idealized view of his family, thus breaking his heart.
Well, it could be that Edward, perhaps jealous of Harry's popularity or a girl he likes, spreads false rumors about Harry. This causes Harry to be ostracized and his heart to break as he loses friends and respect.
Well, one possibility is that it could be about Harry's struggle to adapt to his new disability. Maybe he has to learn new magic or spells to help him move around. For example, he might discover a spell that creates a temporary prosthetic leg. Another idea could be that his friends rally around him, with Hermione researching ways to heal his leg completely and Ron being his emotional support. It could also show how he overcomes the challenges in his daily life at Hogwarts, like climbing the stairs or participating in Quidditch in a different way.
One possible plot could be that they have a major disagreement over a Quidditch match. Maybe Ron blames Harry for losing the match because Harry made a risky move that didn't pay off. This causes a rift between them, and they start to see each other as rivals rather than friends. They compete in everything from academics to getting the attention of a certain teacher.
Well, perhaps he uses some powerful magic he's learned secretly. Maybe he has help from unexpected allies, like a magical creature that can bypass the prison's defenses.
It could be that Ron and Hermione abandon Harry due to a prophecy that they misinterpret. They believe that by being with Harry, they will bring doom to the wizarding world. So they go into hiding. Harry, on the other hand, is determined to change the course of the prophecy. He embarks on a journey to find the truth behind it, all while feeling the pain of his friends' desertion. He has to fight against dark forces that are taking advantage of the situation.
