What could be the possible reasons in a 'ron punched harry fanfic' for Ron to punch Harry?

Another possibility is that in the fanfic's unique plot, there could be some sort of magical influence or dark magic at play. Perhaps a spell was cast on Ron that made him act out of character and punch Harry. It could also be part of a complex plot where Ron is being controlled by an outside force to create drama between him and Harry in the context of the Drarry relationship.

It could also lead to a divide within their group of friends. Hermione, for instance, might be caught in the middle, not knowing who to side with. This could create a lot of tension and conflict among the characters, adding more drama to the fanfic. If the punch was public, it could also damage Ron's reputation among their peers, as punching a friend is not an acceptable behavior in most cases.

Maybe in the fanfic, there could be a misunderstanding between them. For example, Ron might have accidentally broken Harry's trust in some way, like revealing a secret of Harry's that he wasn't supposed to.

The fanfic might be set in an alternate universe where Ron has a different personality. If this new personality clashes with Harry's values or his own personality, then Harry may not like Ron. For example, if Ron is made to be more self - centered in this fanfic, Harry might find it hard to get along with him.

It could be that they lied to Harry about something really significant. In the wizarding world, trust is built on truth - telling. If they told a big lie, like about the true nature of a magical object that was putting Harry in danger, he would be very angry. And if their actions led to the death of someone Harry cared about. For instance, if they made a wrong move during a fight that caused an ally to die, Harry would find it very hard to forgive them.

Perhaps there were some secrets that Ron was keeping from Harry. In the wizarding world, secrets can be a big deal. If Ron had a secret related to his family or some other important matter and Harry found out about it in a way that made it seem like Ron was hiding something bad, it could lead to Harry not trusting him. Also, Ron's friendship with other characters might make Harry jealous or suspicious. If Ron was getting closer to someone Harry didn't trust, it could spill over and make Harry question Ron's loyalty to him.

I'm not sure about a specific 'ron punched harry fanfic' off the top of my head. You could try searching on fanfic websites like Archive of Our Own. They have a large collection of Harry Potter fanfictions and you might be able to find one with that plot there.

In the fanfic, Hermione might regret choosing Ron over Harry because Harry has a different level of understanding when it comes to her academic pursuits. Harry, having faced the challenges of fighting Voldemort from a young age, might have a deeper respect for Hermione's thirst for knowledge and her need to constantly learn and improve. Ron, on the other hand, sometimes showed impatience with Hermione's studious nature.

One possible reason could be a divergence in their goals. Maybe in the fanfiction, Harry has a different approach to fighting Voldemort and Ron doesn't agree with it, leading to a rift. For example, Harry might want to take a more aggressive and risky approach while Ron prefers a more cautious one. This difference in ideology can drive them apart.

It could be due to a misunderstanding. Suppose Ron overhears a conversation between Harry and Hermione that he misinterprets completely. He might think they are plotting against him or don't really consider him a true friend. So in a fit of anger and hurt, he decides to betray them.
