In this fanfiction, Harry's character development could be quite complex. He may initially struggle with his identity, being part of the Malfoy family yet having his own heroic nature. Draco, on the other hand, might experience growth as he has to deal with having a 'different' kind of brother. He could become more empathetic or more resentful. The other Hogwarts students would also be affected. For instance, Neville might see Harry in a new light and the Gryffindors might be more suspicious of Harry's connection to the Slytherin - associated Malfoy family. This would all create a very different character - driven story compared to the original Harry Potter series.
Draco could also change. Having Harry as his brother might make him more protective or more competitive. He might also start to see the flaws in his family's beliefs. As for other characters, Ron and Hermione might view Harry differently and their friendship could be strained or strengthened in new ways.
For Bellatrix, she could start to question her loyalty to Voldemort. Her interactions with Harry might make her realize that there's more to the world than just blindly following the Dark Lord. As for Harry, he could become more aware of the true nature of the Death Eaters at a very young age, which would shape his future battles. He might also develop a sense of pity for Bellatrix in a way, understanding that she's a victim of Voldemort's ideology too.
For Harry, he might become more protective. Since Bella is his sister, he'd feel responsible for her safety. He could also become more in tune with the non - magical world, as he has a family connection there. For Bella, she could gain more confidence. With Harry's magical abilities at her disposal, she might not feel as vulnerable. Also, she might develop an interest in the wizarding world and learn some magic herself.
Harry could also grow in his understanding of the wizarding education system. He realizes that there are many flaws in it. This understanding might lead him to want to make changes in the future, perhaps by influencing how magic is taught at Hogwarts or even in the wider wizarding world. He could start advocating for more inclusive and practical classes after seeing the limitations during his auditing experience.
For Harry, he could become more in - depth in his understanding of Hogwarts' history and magic. Interacting with Helena Ravenclaw might make him more reflective and less impulsive. As for Helena, through her connection with Harry, she could gain a new perspective on the modern wizarding world and the changes that have occurred since her time.
Well, it could have some interesting plots. Maybe Harry being Draco's little brother would lead to a whole new dynamic in the Hogwarts hierarchy. It might change the way the houses interact and the relationships between characters like the Weasleys and Harry.
He might become more of a loner. Since his connection to Bobby Singer is not something the average wizard would understand, he could feel isolated. He may also become more secretive, hiding his knowledge from Bobby's world.
One possible plot development could be the initial shock and confusion from both Draco and Harry. They would have to deal with the reactions of their friends and the wizarding community. Another could be the struggle to find a way to handle the pregnancy in a world where male pregnancy is unheard of, perhaps seeking out rare magic or potions. Maybe there would be a plot where they have to keep it a secret from their enemies who could use this strange situation against them.
One possible plot development is that they form an alliance against a common enemy. Maybe there's a new dark force emerging in the wizarding world, and their combined skills and knowledge are needed. Another is that they start to explore their feelings for each other, which could be more than just friendship. It could be the start of a romantic relationship, which would be a huge change from their traditional enmity.
In this fanfiction scenario, Harry would likely become more cunning in a positive way. He would have to use the Slytherin traits to his advantage while still maintaining his Gryffindor values. The Slytherin students would experience character growth as well. They might start to question their long - held beliefs about blood purity and house superiority. With Harry as their leader, they could become more collaborative with students from other houses, which would broaden their perspectives and make them more well - rounded individuals.
For Harry, he could become more confident in his teaching abilities. He has always been a learner, but now he has to be the one imparting knowledge. The Marauders might develop a new respect for the importance of DADA. For instance, Sirius might see it as more than just a subject to goof around in. Remus could gain new insights into teaching methods that he can later use when he becomes a teacher himself at Hogwarts.
