A story could be about Rose getting involved in a mystery at Hogwarts that involves an ancient magical artifact. She teams up with new friends, using her intelligence and courage, much like her parents, to solve the mystery and protect the school.
Perhaps a plot where Rose discovers a hidden magical ability that neither Ron nor Hermione have. This could lead her on a journey to find out more about this unique gift and its origin in her family's history.
Well, perhaps in the fanfiction, Ron and Hermione discover that Rose has some unique magical abilities even before she is born. This causes a stir in the wizarding world, and they have to deal with unwanted attention from the Ministry of Magic. At the same time, they are also trying to balance their normal lives, like Ron still working at Weasley's Wizard Wheezes and Hermione doing research at the Ministry. They have to find a way to protect their family while also living their lives.
A really interesting plot could be that right before the wedding, a dark wizard from Ron's past tries to disrupt it. Hermione and Ron, along with their friends, have to fight off the threat while still making sure the wedding goes on as planned. It would add a lot of action and adventure to the fanfiction.
A really fun plot could be them going on an adventure during their engagement. They discover an old, forgotten magic related to love and engagement, and they have to solve some puzzles to understand it better. This adventure could strengthen their bond and also give them some unique wedding ideas.
By showing her relationship with her family. For example, her interactions with Ron and Hermione could show how their parenting styles shape her. If Hermione is strict about studies, Rose might rebel or strive hard to please her.
One plot idea could be Hermione's discovery of her true heritage. She could start having strange dreams or visions that lead her to Middle - earth. Once there, she has to learn about Elrond and his world while also dealing with the fact that she is now part of a completely different family and culture. Another idea is that her knowledge from the wizarding world helps Elrond's people in some way, like solving a long - standing magical problem or defending against a new threat.
One plot idea could be that Ron and Hermione accidentally discover a hidden passage in the Chamber of Secrets that leads to an ancient wizarding library. In this library, they find a spell book that has the power to reverse dark magic spells, which becomes crucial in fighting the basilisk's venom. Another idea is that they get trapped in a part of the Chamber that has a time - warp effect, and they have to figure out how to get back to their own time while also dealing with the threats within the Chamber. And a third idea could be that Hermione gets cursed by a relic in the Chamber, and Ron has to go on a solo quest to find the antidote while also protecting Hermione from the lurking danger of the Chamber's secrets.
One idea could be exploring how they handle their kids' magical education. Maybe one of their children has a special ability that requires unique teaching methods. Another could be a story about a family vacation where they visit a new and mysterious magical place and encounter various adventures. Or perhaps a plot where they have to deal with an old enemy from their Hogwarts days who resurfaces and targets their family.
One idea could be that Ron and Hermione accidentally stumble upon a secret passage in Hogwarts while investigating the mystery of the Prisoner of Azkaban. This passage could lead them to a hidden chamber where they find clues about Sirius Black that no one else has discovered yet.
One plot idea could be that Hugo has a unique connection to time - turners. Since Hermione was so involved with time - turners in the past, Hugo might inherit some strange ability related to them. Maybe he accidentally sends himself back in time and Ron and Hermione have to figure out how to get him back.
A possible plot is that they are in bed and start arguing about a minor thing like who left their wand on the wrong side of the bedside table. But then it turns into a playful banter and then a passionate moment as they realize how silly the argument was. Another idea is that they are in bed getting ready to go to sleep and they start talking about their families. Hermione tells Ron about her Muggle parents and how she misses them sometimes, and Ron shares stories about his large family at the Burrow. This conversation deepens their bond as they fall asleep in each other's arms.
