Another possibility is that it could focus on their adventures together. They might go on some sort of mission or exploration within the wizarding world. It could be related to a new threat that has emerged, and they have to use their combined skills and knowledge to deal with it.
Well, they could have a baby, and the story could focus on how they adjust to being new parents. Hermione might be super - organized about the baby's schedule, while Ron would be more laid - back and make the baby laugh a lot. It would be a sweet story of family growth.
One possibility could be a very sweet and romantic evening. They might have a private dinner together, reminiscing about their journey from friends to lovers. Then, they could slow - dance in their room, just enjoying each other's company and the fact that they are finally married.
Well, perhaps they would get involved in the rebuilding of Hogwarts. Ron could use his strategic skills and Hermione her vast knowledge to help make Hogwarts better than ever. They might also start teaching there, passing on their knowledge and experiences to the younger students.
In this fanfiction scenario, Ron could draw on his knowledge of the wizarding world. He might remember some ancient spells or potions that could safeguard Hermione. He'd be really determined to protect her. He could also call on his friends like Harry for help if the situation got really tough.
Perhaps they are there to rescue someone. Hermione might come up with a clever plan involving potions and charms to get past the manor's defenses. Ron, with his loyalty and determination, would be right by her side, ready to take on any danger that comes their way.
In some fanfictions, Ron and Hermione could be at Malfoy Manor for a diplomatic mission of sorts. The wizarding world is in chaos, and they are sent to try and convince the Malfoys to switch sides. This would be a very difficult task as the Malfoys have long been associated with the dark side. But Ron's loyalty and Hermione's persuasion skills could potentially make a difference.
One common theme is family. Since it's 19 years later, they likely have a family of their own, so stories could revolve around family values, sibling relationships among their children, and how they pass on the traditions of the wizarding world to the next generation.
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.
In fanfiction, it could be a very awkward encounter. Ron might be shocked by the Dursleys' rudeness towards magic. He could be quite outspoken about it, which would make the situation tense. Hermione, on the other hand, would probably try to be more diplomatic. She might attempt to explain magic to the Dursleys in a calm and rational way, but they likely wouldn't listen.
In some fanfictions, Ron and Hermione might go on adventures together. They could use their combined skills, Hermione's intelligence and Ron's loyalty and strategic thinking, to explore new magical places and solve mysteries that were overlooked during the main battle.
