Harry might be really angry with Ron and it could damage their friendship. They've been through a lot together, and stealing something as important as the cloak is a big betrayal.
There could also be unforeseen consequences. Maybe the cloak has some sort of protection magic on it that reacts badly to being stolen. It could cause some sort of magical backlash that affects Ron in strange ways, like making him lose his own magical abilities temporarily or causing him to have bad luck.
Maybe Ron is jealous of Harry and wants to have something that belongs to him for a change. The cloak gives Harry a certain freedom and mystery, and Ron might be longing for that kind of experience.
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.
It could be a misunderstanding. For example, Ron might think Harry did something really bad to Hermione or their other friends. Without proper communication, his anger could lead him to punch Harry. Also, if there was some sort of magical influence or dark magic at play that affected Ron's judgment, that could be a reason too.
Well, it could be really awkward for him. He might feel a bit strange knowing that people are writing fictional stories about his two best friends. He could also be a bit protective and might not like the way some fanfictions portray Ron and Hermione. Maybe he'll be amused too, depending on the content of the fanfiction.
Yes, there are some out there. Some fanfictions explore this alternative relationship dynamic in interesting ways. They might rewrite the story's events and character interactions to make it seem more plausible for Harry to be with Hermione instead of Ron.
The plot could start with Harry realizing he has deeper feelings for Hermione than just friendship. He might start spending more time with her, which causes tension between him and Ron. Eventually, he could confess his feelings to Hermione, and she might be conflicted because of her relationship with Ron.
However, from a fandom perspective, it could mean that he missed out on some creative interpretations of his character. Fanfiction often gives new and interesting takes on characters, and by ignoring it, he didn't get to see how fans saw him in different scenarios.
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.
The consequences could be significant. Ron's jealousy and shock could lead to arguments between them. However, if they communicate well, their friendship could survive and even become stronger as Ron learns to accept Harry's relationship.
Well, it might also lead to a split in the wizarding community. Some might side with Ron and Hermione, believing they had a good reason to abandon Harry. Others would be outraged and try to find Harry and bring him back. This could create chaos and internal conflict within the wizarding world, making it vulnerable to outside threats as well.
