Yes, there might be some fanfictions exploring such a dark theme in a more psychological and less graphic way. However, this goes against the general positive relationship depicted in the original 'Harry Potter' series. Writers may use it to explore complex character dynamics under extreme circumstances, but it's not a common or pleasant take on the characters.
In the fanfiction, if Ron finds out Harry is abused, it's a complex situation. Ron's reaction would be multi - faceted. Emotionally, he'd be a mess. He loves Harry like a brother. He might feel guilty for not noticing earlier. Ron would also start to view Harry in a new light, with more compassion and understanding. He would use his Weasley family connections to find resources or help for Harry. Maybe he'd ask his mother for advice or even get his older brothers involved if the abuse was from a powerful source within the wizarding world.
You really shouldn't be looking for this kind of fanfiction. It distorts the essence of the 'Harry Potter' story. But if you were to look, you might try some of the more niche and less - moderated fanfiction platforms. Keep in mind that these are often full of all kinds of content, and this particular theme is not in the spirit of the original work.
Ron might be shocked at first. He could become very protective of Harry, standing up for him against any potential threats. Maybe he would also be a bit angry that he hadn't noticed earlier.
Their friendship would become deeper. Ron would be more protective and more attuned to Harry's emotions. There would be a new level of trust as Harry has shared such a difficult and personal experience with Ron.
Most of the fanfiction in the Harry Potter universe focuses on positive relationships and adventures. The idea of Ron abusing Harry in a romantic context is quite disturbing. There may be some very niche and perhaps disturbing fanfictions out there that might touch on this, but I would not recommend seeking them out. Fanfiction should generally enhance the positive aspects of the original story, not introduce such negative and out - of - character concepts.
Some people might create this kind of fanfiction out of a desire for a very different and edgy take on the characters. They want to explore the darker side of relationships, even if it's completely against the original portrayal of Ron and Harry's friendship.
There are many possibilities. It could be a character from Slytherin who has a long - standing grudge against Harry. They might be using abuse as a means to undermine Harry's confidence and disrupt his relationship in the romance aspect of the fanfiction. Another option could be a dark wizard in hiding who has a personal vendetta against Harry and sees abuse as a way to torment him without attracting too much attention from the wizarding community.
One common theme is the healing process. Ron helps Harry deal with his emotional and psychological trauma. It often shows how their friendship deepens through this difficult time.
Another option is to check out Harry Potter - related fan communities on social media platforms. There might be fans who can recommend or share such fanfictions. For example, on Reddit, there are specific Harry Potter fanfic subreddits where you can ask for this kind of story.
