Fanfiction about Dean, Sam and Harry being brothers: What are some interesting plot ideas?

One idea could be that Bella discovers she has special powers because of her relation to Sam and Dean. Maybe she can communicate with spirits in a unique way that helps them on their hunts.

One idea could be that they go back to the time when their parents first met. They could try to prevent some dark force from interfering with their relationship, which would change the course of their family's future. Another plot could be them going back to a crucial moment in the fight against a major demon, and they use their present - day knowledge to change the outcome for the better.

One interesting plot idea could be that they discover they are brothers early on. They then have to deal with the shock of it within the context of the Hogwarts houses. Harry might try to bring Draco closer to his friends, which could lead to some really funny and awkward moments as Draco is used to his Slytherin clique. Another idea is that they work together to uncover secrets about their family, secrets that could change the wizarding world's view of their family's past.

One plot idea could be that they discover their brotherhood through a magical accident. Maybe a spell goes wrong during a Quidditch match and reveals their hidden family connection. They then have to navigate the wizarding world together, facing both admiration and envy from others.

Perhaps they start off not knowing they are brothers. Harry is at Hogwarts and Percy is at Camp Half - Blood. But then strange things start to happen. They both start having visions of the other's world. Eventually, they meet and find out they share the same father. Then they go on a journey to find out more about their family history and in the process, face challenges from both the wizarding and demigod communities who are against their union.

A plot idea could be that Dean discovers he has some sort of inherited power that could be passed on to the baby. This leads to a race against time to figure out if it's a good or bad power. Lisa, on the other hand, is trying to prepare for the baby's arrival in a normal way, like setting up the nursery. Their different focuses create some interesting tension in the fanfiction.

Well, a plot could involve them trying to keep it a secret at first. They could be worried about how the world around them, especially in their line of work, would respond to two men being pregnant. As the pregnancy progresses, they might start to prepare a nursery together, with each having different ideas about how it should look.

Maybe in the fanfiction, Rachel and Sam are in a secret relationship when they find out about the pregnancy. They then have to decide whether to go public or keep it a secret for a while longer. This could lead to a lot of drama as they try to hide it from their friends who might not approve. Another aspect could be their journey to prenatal classes, where they meet other expecting couples and learn more about pregnancy and childbirth.

In this type of fanfiction, it could be really interesting. Harry might bring his own set of skills and a different perspective into Sam and Dean's world. Maybe he'd introduce some unique magic that could help them in their hunts. For example, he could use spells to track down monsters more easily or protect them from certain types of dark magic that they haven't encountered before. It would be a cool crossover, mixing the world of Harry Potter with the Supernatural universe.

Maybe an angelic or demonic entity implants something in Dean that causes the pregnancy. Dean might initially be in denial and try to hide it from Sam. As the pregnancy progresses, he starts to experience strange powers or sensations. This could lead to a journey where they discover that the unborn entity is a key to saving the world from a great evil.
