Perhaps Harry overhears a very private and heartfelt conversation between Ron and Hermione. He might realize that their relationship has deepened in a way he hadn't noticed before. This could make Harry feel a bit left out at first, but then he would probably be happy for them. He could also use this new knowledge to be more understanding of their actions and decisions in the future.
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.
If Ron and Hermione leave Harry in the fanfiction, it would change the entire fabric of the story. Harry would have to reevaluate his relationships with other characters. For example, he might turn to Neville for support more often. Also, the power dynamic within the wizarding world could shift. Since Ron and Hermione were important figures in the fight against Voldemort, their absence could give the Death Eaters an advantage, or it could inspire others to step up in unexpected ways. Harry would be forced to grow in ways he hadn't before, and it would be a journey full of self - discovery and new challenges.
Harry might react with shock. If he overhears something unexpected like Ron and Hermione confessing their love for each other, it would be a big surprise. He might stand there frozen for a moment, not knowing how to process it.
One possibility is that Snape would be extremely strict with them at first. Given his past relationship with Harry especially, he might struggle to show affection openly. But over time, he could come to understand the trio better. Harry would likely be the most resistant to Snape's parenting at the start, but as Snape showed his genuine care, Harry might warm up. Hermione would probably be eager to learn from Snape, seeing his vast knowledge. Ron, on the other hand, might find Snape's gloomy demeanor a bit off - putting, but with Hermione and Harry's influence, he'd also adapt.
Well, Harry might become very bitter. He could turn to other allies like Neville or Luna for support. He might also start to question all of his relationships and become more withdrawn.
Harry's reaction would depend on the nature of the fanfiction. If it's a cute, romantic fanfiction about Ron and Hermione, he might smile to himself and think it's kind of sweet. However, if it's something that distorts their characters or has a negative slant, he could get defensive. He might even try to find out who wrote it and why they would write such a thing about his friends.
One possibility is that Ron would be heartbroken and might become a bit of a loner for a while. He could focus more on his career at the Ministry or with the Weasley's Wizard Wheezes. As for Hermione and Remus, they might face a lot of backlash from the wizarding community who are used to the Ron - Hermione relationship.
In fanfiction, the possibilities are endless. It could be that they go on an adventure to a previously unknown magical land or face a powerful dark wizard who was thought to be defeated.
Well, it could go in many directions. They might travel to a previously unknown magical realm or encounter creatures that were only hinted at in the original series.
Well, in certain fanfiction scenarios, Ron's jealousy could be a factor. He might feel overshadowed by Harry for so long that it finally drives a wedge between them, and Hermione, being in a relationship with Ron, gets caught up in it. Another possibility is that a prophecy or some ancient magic forces them to make choices that seem like a betrayal to Harry, but they believe they are doing it for the greater good.
