In some fanfiction, the pregnancy could be a catalyst for a change in the wizarding world's attitude towards Muggle - borns. Since Lily is Muggle - born and she's having a child with a pure - blood wizard, it could start a movement of acceptance. There could be scenes where they attend wizarding events and people start to see that Muggle - borns are just as important and magical as pure - bloods, especially with the new life that is about to come into the world.
Well, an interesting idea could be that Lily discovers she has some new, pregnancy - related magical powers. Maybe she can communicate with the baby in the womb through magic. It would be a really unique and heart - warming concept, seeing her and James have little magical conversations with their unborn child.
One idea could be that they face challenges from the wizarding world due to their relationship while Lily is pregnant. Maybe there are threats from dark forces who want to harm them or their unborn child.
There could also be a plotline where their pregnancy is put in danger. Maybe there are dark forces at work in the wizarding world that target them because of their unborn child. This can create a lot of tension and drama, as they have to fight to protect their family. It can also be a way to explore the darker side of the Harry Potter universe and how Lily and James would handle such threats while being pregnant.
A really interesting plot could be that James and Lily, alive, work with Dumbledore to create a new school of magic. This school would focus on teaching students how to defend against the Dark Arts in a more practical and hands - on way. Harry would be one of the first students there. They could also develop new magical artifacts that could help in the fight against evil. And the family could have adventures all over the world to find the ingredients and knowledge needed for these new creations.
One interesting plot idea could be that Lily and James, alive and well, decide to train Harry in magic from a very young age. This would make Harry an even more powerful wizard earlier on. They could also use their influence to reform the wizarding world, starting with Hogwarts. For example, they might introduce new courses that focus on both light and dark magic, teaching students how to defend against the dark arts in a more comprehensive way.
A plot could revolve around the challenges they face during the pregnancy. For example, Lily might have some difficult symptoms, and James has to learn how to take care of her while also dealing with his own insecurities about becoming a father. They could also face some threats from the wizarding world's dark forces, adding an element of danger to the story.
One plot idea could be that James and Lily are brought back to life briefly and they meet Harry at a crucial moment in his fight against Voldemort. They offer him words of wisdom and strength that he didn't have before, which gives him an edge in the final battle.
There are fanfictions where the pregnancy is a central theme in a story that looks at the family's past. For example, it could be told from the perspective of a family heirloom. The heirloom has been passed down through generations and during Lily and James' pregnancy, it starts to show strange signs. It could be a magical object that is somehow linked to the fate of their unborn child, and as Lily's pregnancy progresses, the mystery of the heirloom unfolds.
One interesting fanfiction could be about James and Lily's time at Hogwarts before they got together. It might explore how their relationship developed from initial dislike to love. For example, a story could show James maturing from a prank - loving boy to someone worthy of Lily's love.
One idea could be exploring how the wizarding community reacts to the news. Maybe there are speculations about the child's future and special powers. Another could be focusing on Lily's relationship with James during her pregnancy, like how they prepare for the baby together.
One idea could be that they return with new magical abilities. Maybe James has the power to control time briefly, which he uses to prevent some small tragedies in the wizarding world. Another could be that they return to find that Harry has changed the wizarding world in ways they never expected, and they have to adapt to this new world order.
