A possible plotline is dealing with the media in the wizarding world. As Harry is a very well - known figure, their marriage would be big news. There could be tabloids writing all sorts of things about them, and they would have to handle the public scrutiny. Also, a plotline could involve them mentoring young wizards. Their unique relationship could be an example for the younger generation to learn about acceptance and different kinds of love. And they could pass on their magical skills in a new and innovative way.
There could be a plotline where they are haunted by the past. Draco's past actions during the wizarding war, and Harry's traumas from the same war. Blaise might also have his own demons. They would need to face these past issues together and heal as a group. Another interesting plotline could be them participating in a magical tournament. But not as competitors against each other, but as a team. They would use their combined magic and strategies to outwit other teams and emerge victorious.
A great plotline might involve a magical competition where Draco, Blaise, and Harry are all forced to compete. As they face various challenges, they start to understand each other better. For example, they realize that they all have the same fears about the future of the wizarding world. It could also be a plotline where they are all transported to an alternate dimension and have to rely on each other to get back home.
One common plotline is the redemption arc. The OC could be the key factor in Draco's redemption. For example, the OC might see the good in Draco that others overlook and encourage him to break away from his dark family ties. Harry could be initially skeptical but gradually come to accept Draco's change. Blaise might be caught in the middle, trying to support his friend Draco while also maintaining his own standing. Another plotline could be a mystery adventure. The four of them team up to solve a mystery that threatens Hogwarts. Each character brings their own skills to the table - Harry's courage, Draco's knowledge of the Slytherin side of things, Blaise's cunning, and the OC's unique perspective or ability.
One interesting plotline could be how Harry and Blaise's friendship develops over time. Maybe they start off as rivals in school, but as they get to know each other better, they find common interests like a love for magical creatures. This could lead to them working together on projects related to it.
One interesting interpretation could be the complex relationships between the characters. Harry, Draco, and Blaise might have unique dynamics that deviate from the original story. For example, their friendships or rivalries could be re - imagined in ways that add new layers to their personalities.
Another idea is that the OC is a Muggle - born with an amazing talent for potions. They end up in a class project with Harry, Draco, and Blaise. Their different approaches to the project (Harry's courage, Draco's ambition, Blaise's shrewdness) and the OC's out - of - the - box thinking create a really interesting dynamic as they compete and also learn from each other.
One plot idea could be a story where Blaise and Draco have to team up with Harry and Hermione for a special magical tournament. They start off as reluctant allies but gradually learn to respect each other's skills. Another could be a mystery - something strange is happening at Hogwarts and the four of them must put aside their differences to solve it. For example, students are losing their magical abilities one by one, and they suspect a dark magic artifact hidden in the castle.
One great fanfiction is 'The Unlikely Bond'. It beautifully explores the complex relationships between Harry, Draco, and Blaise. It shows how they overcome their initial differences and form an unexpected friendship. The character development in this fic is really well - done.
One interesting plotline could be that they discover their twin relationship early on and try to keep it a secret from everyone at Hogwarts. They might secretly help each other out in classes and with their rivalries against other houses.
One interesting plotline could be Harry and Draco being deaged and having to rely on each other in a world that seems new to them again. They might form an unexpected friendship as they don't have the pre - conceived notions from their older selves. For example, they could team up to solve a mystery in Hogwarts that only they, with their combined knowledge from before, can figure out.
Well, in some 'Draco Adopts Harry' fanfictions, a great plotline is how Draco overcomes his past enmity towards Harry. He starts to see Harry as a person in need rather than an enemy. There could be a plot where they work together to uncover secrets about Harry's past that Dumbledore might have hidden. And then, Draco has to protect Harry from those who don't want the truth to come out.
