One possible plot could be that in an alternate magical universe, a spell goes wrong and causes both Bill and Charlie to experience some of the physical symptoms of pregnancy, while Hermione, being the brilliant witch she is, tries to find a way to reverse the spell. Along the way, they could have humorous exchanges about the situation and learn more about the magic behind such strange occurrences.
In a more creative fanfiction plot, there could be a magical artifact that when touched by Bill, Charlie and Hermione, gives them the ability to carry a child (even though it's not biologically possible in the normal sense). This could lead to a story where they have to navigate the new emotions and physical changes. Hermione might be more analytical about it, while Bill and Charlie are more in shock at first. As time progresses, they form a unique bond over this shared experience and the fanfiction could explore their growth as characters through this strange situation.
One plot idea could be the challenges they face in the wizarding world due to their unexpected pregnancy. Maybe there are speculations and gossips among the wizarding community. Another could be how they prepare for the arrival of the baby, like choosing a magical nursery and magical baby items. And a third idea might be how they deal with the reactions of their friends and family, some being supportive and others being skeptical.
One possible plot could be that Hermione meets Bill and Charlie during a magical creature research project. Bill's extensive knowledge of magical creatures from his work with Gringotts and Charlie's expertise from his time at the dragon reserve in Romania could complement Hermione's academic approach. They might start off a bit skeptical of each other, but as they work together, they come to respect and rely on one another, with Hermione learning a great deal from their practical experiences.
One plot idea could be them preparing for the baby. Like Bill trying to make their home more safe and Fleur decorating the nursery in a very French - inspired way.
Perhaps in the fanfiction, there is a magical tournament being organized that requires the skills of all three. Harry is known for his courage and spell - casting abilities, Bill for his worldly knowledge and dueling skills, and Charlie for his physical strength and ability to handle dangerous magical beasts. They team up to compete and face various challenges along the way.
One plot idea could be Nejire's journey through pregnancy while still trying to be a hero. She might face challenges like hiding her condition from villains who could target her. Another could be the reactions of her friends and loved ones, like how they support her and deal with the changes in their relationships.
One plot idea could be that they are forced into an unexpected union due to some magical circumstances. Maybe a dark magic spell backfires and binds them in a way that leads to Hermione becoming pregnant. Another could be a story set in an alternate universe where they are on the same side and fall in love over time, and the pregnancy is a result of their new - found relationship. It could explore how they deal with the reactions of their respective families and friends.
Perhaps it's a result of some dark magic interference. The story could focus on how Harry and Hermione struggle to find a way to reverse it at first. But as time goes on, they start to form an unexpected bond with the unborn child in a magical way. They might face discrimination or suspicion from some in the Hogwarts community who fear the unknown nature of this magical pregnancy, and they have to prove that they can handle it and that it's not a threat to the school.
One common theme is friendship. Many fanfictions focus on how Hermione can form deep and meaningful friendships with Bill and Charlie. Another theme is adventure. Given Bill's work with Gringotts and Charlie's with dragons, they often embark on exciting adventures with Hermione in these stories.
They could help Harry by teaching him new spells. Bill might teach him some advanced defensive spells he learned as a curse - breaker. Charlie could show Harry some unique ways to use magic around magical creatures. Hermione would of course be there to ensure Harry studies hard and understands the theory behind the spells.
In a fanfiction scenario, perhaps Hermione has a research project and enlists the help of Bill, Charlie, and Harry. Bill could offer insights from his travels, Charlie might contribute with his expertise on dragons as it relates to the research, and Harry would be there for moral support and to offer his unique perspective as the Boy Who Lived. It could be a story of friendship and cooperation in the magical community.
