A frequent plotline is the cultural clash between Hermione and the people of Salazar's time. Hermione is a modern - day witch with different values, and she has to navigate the more traditional and sometimes more prejudiced society of the past. There could also be a romantic plotline where Salazar initially doesn't trust Hermione but gradually falls in love with her as she shows her strength and intelligence. And of course, there could be a plot where they face some external threat together and their relationship grows stronger through that shared experience.
Often, there's a plotline about Hermione uncovering some long - lost secrets of Salazar. Maybe she finds a hidden chamber or a magical artifact that only she can access because of her connection to him. This discovery could lead to her having to prove herself worthy to the Hogwarts community as Salazar's wife. There might also be a plot about Hermione using her knowledge from the future to help Salazar in his time, like preventing some sort of dark magic from spreading in the early days of Hogwarts.
One common plotline could be Hermione trying to modernize the Hogwarts traditions that Salazar Slytherin started. Since she has a different perspective from the present time, she might want to make changes. Another could be Hermione facing opposition from the other founders' descendants or even the Hogwarts ghosts who are used to the old ways.
A common plotline could be them facing prejudice together. Since Lupin is a werewolf, they might have to deal with people's narrow - minded views.

It could also involve them going on adventures to protect the wizarding world and in the process, their relationship deepens.
One common plotline is them trying to change the Slytherin house's negative image. They bring their Gryffindor values like bravery and loyalty into Slytherin and try to reform it from within. Another is their relationship with the other Slytherins. They might have to deal with the pure - blood supremacist ideas that some Slytherins hold. Some fanfictions also explore how they adapt to the Slytherin common room and its more secretive atmosphere.
One common plotline could be that Hermione is betrayed by her friends in Hogwarts. For example, they might believe false rumors about her and turn their backs on her. Another could be a romantic betrayal, like if Ron, in a different take on the story, cheats on her or breaks her heart in some way. Sometimes, she could be betrayed by the wizarding community as a whole, perhaps being wrongly accused of dark magic and no one believing in her innocence.
A common plotline involves Hermione unlocking some sort of hidden power or knowledge that was left behind by Salazar Slytherin. For example, she might discover a long - lost spellbook of his and learn some powerful magic from it. Another plotline could be that she is chosen by some ancient Slytherin - related magic to carry out a task that has been long forgotten, which could put her at odds with some of the Hogwarts faculty or her friends initially as they misunderstand her intentions.
One common plotline could be Hermione forming a closer friendship with Fleur. Since she hates Ron, she might turn to Fleur for support and they could end up having adventures together, perhaps in the wizarding world outside of Hogwarts.

And sometimes, there could be a plot where she believes she can change Voldemort's evil ways through their relationship.
In some fanfictions, the focus could be on Hermione's child's unique abilities or challenges. Since Hermione is very intelligent, her child might inherit her smarts but also have some special magical gift that she has to figure out how to handle on her own. Maybe the child has an uncontrollable power and Hermione has to search for ways to help the child manage it without a partner to support her. It could also involve her reconnecting with old friends from Hogwarts who either support or question her decisions as a single mother.
Often, there are plotlines centered around protecting Hermione. Since werewolves are sometimes seen as dangerous, the werewolf mate has to prove that he can keep Hermione safe, not only from the outside world but also from his own werewolf side during full moons. And there could be a plot where they work together to change the perception of werewolves in the wizarding society.
Often, there are plotlines where Hermione as a pureblood princess has special powers or abilities that come with her status. For example, she might have an innate magical ability that is unique to pureblood princesses in the fanfiction world. This could then be used to save the day in various situations, like fighting against dark wizards or solving complex magical mysteries.
