Perhaps she discovers a hidden power within herself that neither of her parents had. This power could put her in a unique position in the wizarding world. She might have to decide whether to use it for good or be influenced by her mother's dark side. For example, if she has a special gift for mind - reading, she could use it to help people or manipulate them like Bellatrix would.
Another plot could revolve around her relationships at Hogwarts. She might form unexpected friendships with students from different houses. Her family background would make her an outcast initially, but as her true nature is revealed, she could gain the respect and loyalty of those around her. This could lead to her having to protect her friends from dark wizards who want to use her as a pawn because of her parents.
One possible plotline could be the daughter's struggle with her father's complex reputation at Hogwarts. She might face prejudice from students who remember Snape's dark past. Another could be her discovery of her father's true love for her mother, which was hidden for so long. And she could also have a special talent in potions, just like her father, and use it to outshine others in her classes.
One possible plotline could be Hermione's discovery of her true parentage. Maybe she finds a hidden letter or a magic - bound memory that reveals the truth. This would send her into a state of shock and confusion as she tries to reconcile her own values with the fact that her mother is Bellatrix, a known Death Eater.
Well, a plot might involve Bellatrix being involved in some sort of forbidden magic experiment at Hogwarts. She could be trying to impress the Dark Lord even as a student. Or it could be about her trying to undermine Dumbledore's authority at Hogwarts. For example, she might spread rumors or cause small acts of chaos around the school to show her disdain for the more light - hearted and inclusive Hogwarts environment.
Another plotline could be Hermione exploring her dark magic heritage. She might be tempted to learn some of the spells that Bellatrix was known for, but then struggle with the moral implications. This internal conflict could be a major part of the story, as she tries to balance her Gryffindor values with her new - found connection to a dark past.
One possible plotline could be Snape finding drunk Harry in the Hogwarts corridors. Snape, being the strict teacher, might initially be angry but then realizes Harry is in a vulnerable state. He could take Harry to his office to sober him up and in the process, they have a conversation that reveals some hidden feelings or understanding between them.
Perhaps the marriage law is part of a new wizarding world order to promote unity between different factions. Snape, being from Slytherin and Harry from Gryffindor, their union is seen as a symbol. They might face a lot of opposition from various groups. Some of Snape's old Death Eater associates might try to undermine the relationship, while some of Harry's friends might be very skeptical. However, through facing these challenges together, they gradually develop a bond that surprises everyone, including themselves.
Well, there could be a plotline where Snape's father was an inventor in the wizarding world. He might have created some powerful magic items or spells that were lost or forgotten. Snape, in the fanfiction, could be on a quest to find and revive his father's work. Another idea is that Snape's father was a key figure in a war long before Voldemort's rise, and his actions had consequences that Snape has to deal with in the present day of the fanfiction. There could also be a plotline where Snape's father was a mentor to some other important character, and this connection has implications for Snape's life and the overall story.
One possible plotline could be the baby daughter inheriting Loki's mischievous nature. She might play little tricks on the Asgardians, like changing the color of Thor's hammer for a day. Another could be her growing up in a world that is sometimes hostile to her because of her father's reputation, and she has to prove herself to be different. And perhaps she discovers a unique power within her that no one in Asgard has ever seen before.
A plotline might involve a dark magic situation where Snape has been cursed and Harry, as his donor, is the only hope to break the curse. As Harry gets involved, he uncovers secrets about Snape's past that change his perception of him. Meanwhile, Snape has to deal with his pride and accept help from someone he has long disliked, leading to a complex emotional journey for both characters.
Perhaps Snape, in a moment of weakness or out of some deep - seated sense of responsibility, decides to protect Harry in an extreme way. He treats Harry like a pet in that he provides for all of Harry's needs but also restricts his freedom. This could lead to a lot of internal conflict for Harry, who is used to being independent. Meanwhile, Snape has to deal with the other characters in the wizarding world who might not understand his motives for treating Harry this way.
