In a fanfiction plot, they could decide to have an engagement party where all their Hogwarts friends reunite. But then, an old enemy from Hogwarts days resurfaces and tries to disrupt the party. This forces Harry and Ginny to work together with their friends to stop the chaos. They might also use this time to plan their wedding in a way that reflects their values and the lessons they've learned at Hogwarts. Their engagement could also be a time when they start to think about how to make the wizarding world a better place for future generations.
One plot idea could be that they plan a magical wedding that combines both their families' traditions. Another could be that they face some sort of dark magic threat right after getting engaged which tests their relationship. Maybe they discover a long - lost magical artifact during their engagement that has a connection to their future together.
Well, a really interesting plot could involve Ginny and Harry having to keep their engagement a secret at first because of some political unrest in the wizarding world. As they try to keep it under wraps, they have all sorts of close calls and comical moments. Also, perhaps they take a magical journey to find the perfect place for their future home as part of their engagement celebration, and along the way, they encounter strange and wonderful magical creatures.
One great fanfiction could be where they have a magical wedding at Hogwarts. All their friends from different houses come together to celebrate. The ceremony might include spells that create beautiful flower arrangements in mid - air and a Patronus choir. Ginny would look stunning in a traditional white wizarding dress with lace made of unicorn hair, and Harry would be in his best robes.
A possible plot could be that the child is sent back in time accidentally. In the past, they have to use their knowledge of modern magic (which is different from the magic of that time) to survive and also make sure not to change history too much. Along the way, they learn more about their family's history and the roots of the wizarding world that their parents might not even be aware of.
Well, a plot could be that Ginny is a Slytherin spy within Gryffindor. She's secretly feeding information to Slytherin about Gryffindor's plans in Quidditch or other competitions. But as she does this, she starts to feel conflicted because she really likes her Gryffindor friends.
A possible plot is that Ginny discovers she has some special magical ability related to the pregnancy. Maybe she can communicate with the unborn baby through magic, and they have to figure out what it means. Also, Harry could be super protective, and there could be some comical moments where he overreacts to small things, like Ginny reaching for a high shelf.
Another idea is that their marriage is part of a prophecy. It could be that their union is crucial for the long - term peace and stability of the wizarding world. This would add a lot of weight and significance to their relationship. There could be different factions in the wizarding world who either support or oppose their marriage based on this prophecy.
Imagine Ginny and Harry having a quiet moment together, looking at the Hogwarts castle from afar during their engagement. They remember all the good and bad times they had there. Ginny might hold Harry's hand tightly and say how she's so glad they found each other in the end. And when they receive well - wishes from their friends all over the wizarding world, it makes them feel so loved and supported. There could also be a moment when Ginny's brothers give Harry a hard time in a fun way, but also show their acceptance and love for him as Ginny's future husband, which would be both emotional and heartwarming.
A third plot could be a story set during a big wizarding festival. Ginny and Bill are both involved in the preparations, but things start to go wrong. They must work together to fix the problems and save the festival. During this time, they might also have to deal with family drama as other Weasleys get involved, and through it all, their bond as siblings - in - law (or just as Weasleys) becomes stronger.
One plot idea could be that Arthur discovers Ginny has a special magical talent that she's been hiding out of fear. He then helps her gain confidence in using it. For example, it could be a unique form of wandless magic. Another idea is that they go on a magical adventure together, like exploring an ancient, forgotten wizarding site. There, they encounter strange magical creatures and have to use their combined knowledge and skills to get out safely.
One plot idea could be that Ginny and Lily Luna Potter discover a hidden magical ability within the family that has been long forgotten. They embark on a journey to uncover the secrets behind it, facing various magical creatures and ancient spells along the way.
One idea could be the twins inventing a new type of magical prank product that has unexpected effects on Hogwarts. For example, it might make the staircases act even more erratically than normal, causing chaos throughout the school.
