There could also be a situation where they are competing with Harry for something, like a powerful magical item or a position in a wizarding organization. In their eagerness to win, they might use underhanded tactics that cause harm to Harry. For instance, they could steal his research notes related to the item, causing him to waste a lot of time and energy, and also feeling betrayed by his friends.
There's 'Ron's Pain'. In this fanfic, Ron gets cursed during a mission. The description of his pain and his fight to overcome it is really well - written. It also shows how his relationship with Harry and Hermione is tested in such a difficult situation.
Another possibility is that the fanfiction writer wants to explore a different side of their relationships. By having Hermione and Ron hurt Harry, it shows the complexity of human (or in this case, wizard) emotions. It could be a way to show that even the strongest friendships can have cracks and that mistakes can be made. It also allows for character development as Harry has to deal with this new situation, and Hermione and Ron may later realize their mistakes and try to make amends.
Writers might create Ron Weasley hurt fanfictions to add more drama to the existing Harry Potter universe. Ron is a beloved character, and seeing him in a hurt state can create intense emotions among readers, which makes for an engaging read. It also allows for exploring relationships, like how Hermione and Harry would react to his injury.
Often, Ron might get hurt while exploring a dangerous place like an old wizarding ruin. His friends then have to find a way to get him out safely and also deal with any curses or traps that are activated by his injury. Sometimes, Ron can be hurt by a magical creature too, like a basilisk or a werewolf. This would lead to a race against time to find a cure and also deal with the threat of the creature.
There's also 'When Ron Fell'. In this fanfic, Ron has a bad fall during a Quidditch match. It shows how the other players react, especially Harry and Hermione. They are by his side throughout his recovery, and the story is filled with a lot of touching moments that highlight their bond.
Another theme is emotional hurt. Such as Ron feeling left out or betrayed. This often leads to stories about his journey of self - discovery and how he heals his emotional wounds. For instance, if he feels betrayed by a friend, the story might be about how he learns to trust again.
One common theme is redemption. Draco, who was a bully in the original series, often goes through a journey of self - redemption in these fanfictions. And Hermione is usually the one who either challenges or helps him in this process.
Forbidden love is also a big theme. Given their different backgrounds and the history between Gryffindor and Slytherin, their relationship is often seen as something that goes against the norms of the wizarding world. Stories explore how they deal with the secrecy and the challenges that come with it.
