The story would progress with a lot of drama. There would be the initial shock and then they'd have to tell their friends. Some might be supportive, like Ginny perhaps, but others might be disappointed, like Dumbledore who might have had different plans for them. Harry and Hermione would then have to make decisions about their future, whether to continue their studies or focus on the baby.
If Harry accidentally got Hermione pregnant in fanfiction, the story would take a very different turn. Their focus would shift from their normal adventures and studies to more practical matters. Hermione would likely research all she could about magical pregnancies and how to take care of a baby in the wizarding world. Harry, on the other hand, would be thinking about how to provide for his new family. Their relationship with other characters would also change. For instance, they might become more distant from some of their schoolmates who are more focused on the typical Hogwarts life. But they could also form new alliances with those who are more understanding and empathetic towards their situation. As the pregnancy progresses, they would face various challenges, both internal and external, which would shape their characters and the overall direction of the story.
The story could progress with Hermione constantly plotting her escape. She is a resourceful witch, after all. She might use her magic in clever ways to outwit Draco and his allies. Draco, realizing she's not an easy target, might start to respect her in a strange way.
The story could progress with the group taking on a more defensive stance. They might avoid battles that are too risky to protect Annabeth and the unborn child.
If Hermione got pregnant, their relationship would be full of conflict. Tom has his dark past and tendencies. Hermione would be constantly worried about the influence he could have on the child. She would try to bring out the good in him, while he might struggle between his old ways and his newfound family. Their relationship would have to evolve as they face the challenges of raising a child in a world full of magic and danger. Tom might have to face his own demons more seriously to be a part of their family.
It would deepen on an emotional level. They would have to communicate more about their future and the responsibilities of raising a child. Hermione might rely on Harry more for emotional support during her pregnancy, and Harry would grow to be more nurturing towards Hermione.
There could be a whole new plotline involving the werewolf packs. Maybe Fenrir Greyback had a specific reason for biting Hermione, and his pack might be involved in some grander scheme. Hermione could be caught in the middle of a werewolf power struggle, having to decide which side to take or how to use her new position within the werewolf community to bring about peace or change.
In fanfiction, if such a situation were to occur, it would likely cause a great deal of chaos. Harry and Hermione would have to face the unexpected pregnancy at a young age while also dealing with their duties and the expectations of their friends. Their relationship would be put under extreme stress, and they'd need to figure out how to balance their magical lives with impending parenthood.
The story could progress with Harry trying to find a way to turn back. He might search for ancient spells or magical artifacts that could reverse his condition. His friends would be desperate to help him, and they'd start their own investigations. Maybe Hermione would scour the library for any information on wraiths and how to reverse the transformation.
The story could progress with Harry exploring his new powers. He might start by accidently using them in the wizarding world and causing a stir. Then, he would have to figure out how to control them.
In the beginning, Batman would instill in Harry a sense of vigilance and a desire to protect the innocent. As Harry enters the wizarding world, he'd be an outlier. He might face some resistance from the more traditional wizards. But he'd also introduce new ideas. For example, he could suggest a more organized approach to fighting the dark forces, similar to Batman's methods. His relationships with the teachers would also be unique. Some might admire his different perspective, while others might be skeptical. As the story unfolds, Harry would likely be at the center of a clash between the old ways of the wizarding world and his new - age ideas influenced by Batman.
The story would likely progress in a very different direction. Harry would no longer be just a wizard. His new vampire nature would make him an outcast in many ways. He might be hunted by some in the wizarding community who see vampires as a threat. At the same time, he could meet other vampires who have different motives. Some might want to use him for his connection to the wizarding world, while others might want to help him. His journey would be one of self - discovery, trying to balance his two natures and figure out where he belongs in this new and complex situation. He would also have to deal with the fact that his lifespan might be greatly extended, which would change his perspective on life and his future plans.
