Typically, it starts with the revelation of the unexpected relationship. Then, Hermione often has to deal with the stigma of being related to a Death Eater. She might struggle with her own identity, wondering if she has any of Rodolphus' traits. Some storylines have her trying to redeem the family name or break away from the dark past associated with it.
Well, in many of these fanfictions, the plot develops around Hermione's internal conflict. Since Rodolphus is a known Death Eater, she has to face the prejudice from the wizarding world. The story could also involve her learning dark magic secrets from her supposed father's past, either to use them for good or to keep them from falling into the wrong hands. And there are often sub - plots about her friends' reactions, like Harry and Ron being shocked and having to adjust to this new reality about Hermione.
Typically, in these fanfictions, Hermione's identity as Voldemort's daughter shakes up the whole wizarding world. It usually starts with her being the only one aware of this fact. As she tries to come to terms with it, she may start to have strange dreams or visions related to Voldemort's past. These could provide her with clues about his motives and the secrets of his dark magic. Her relationship with other characters changes drastically. Her friends might be initially distrustful, but as the story progresses, they come to see that Hermione is still the same person they knew. Meanwhile, Hermione might be on a quest to find out if there are any other family members she has on her father's side, which could lead to more adventures and revelations.
One way the storyline could develop is that Hermione would struggle with her identity. She might initially be in denial about her father's Death Eater past. For example, she could discover it accidentally and then have to face the prejudice from her friends at Hogwarts. This would create a lot of internal conflict for her as she has always been a defender of justice and against the Dark Arts.
It could start with animosity. Rodolphus has been a Death Eater and Hermione is a Muggle - born, so there would be initial hatred. But if they were forced to work together, say in a dangerous mission to save the wizarding world, they might slowly gain respect for each other. Hermione's knowledge and Rodolphus' experience could be complementary.
As the pregnancy progresses, Bella often experiences changes that are both physical and mental. Physically, she might have a much tougher time than a normal human pregnancy because of the vampire - human mix. Mentally, she has to deal with the fear of the unknown. The story might also focus on how Edward and Bella's relationship is affected. They could grow closer as they face this new challenge together, or there could be some strains due to their different views on the pregnancy.
Well, often it begins with Sarada seeking Naruto's advice on something important, like her future as a ninja or her family issues. Naruto, being the Hokage, has a lot of wisdom to offer. From there, they get involved in a series of events in the village, like dealing with a new threat or helping a group of villagers. Their relationship develops as they face these challenges together, and Sarada gradually grows under Naruto's influence, both as a ninja and as a person.
Often, it starts with the discovery of the pregnancy. There's shock and then joy. Then they start planning. Maybe they tell their closest friends first. As the pregnancy progresses, there could be some drama like a threat to Regina or the baby. Robin Hood would then step up to protect them. Towards the end, there's the anticipation of the birth and all the final preparations.
Often, it starts with the slapping incident which creates immediate conflict. Then, Hermione might be outraged and seek justice or revenge, which drives the plot forward. For example, she could go to Dumbledore about it.
Often, it starts with the introduction of the marriage law. Then, Hermione's reaction to it is shown. It might be shock, defiance, or immediate acceptance depending on the writer's take. For example, if she's against it, she may try to find loopholes in the law.
In these fanfictions, writers first need to bridge the gap between their very different personalities and backgrounds. Since Hermione is intelligent and values justice, and Rodolphus was a Death Eater, there's a huge divide. The pregnancy could be the result of an unexpected event that then forces them to communicate. As they deal with the reality of the pregnancy, they might gradually learn to respect each other. Hermione could teach Rodolphus about redemption and he could show her a different side of the wizarding world she hadn't seen before. This way, their relationship grows from a forced coexistence due to the pregnancy to a more complex and nuanced bond.
The orphan status in these fanfictions usually deepens her sense of determination. Since she doesn't have the safety net of her parents, she has a stronger drive to succeed. This can be seen in how she approaches challenges at Hogwarts. She might be more tenacious in her pursuit of knowledge or in standing up to bullies like Draco. Also, it can make her more empathetic towards other characters who have faced hardships, leading to new relationships and storylines.
