In some of these fanfictions, a great plot twist is when Hermione's switch to Slytherin causes a rift among her old Gryffindor friends. However, this rift actually leads to a deeper understanding between the houses in the long run. She might also start to question the values she was taught in Gryffindor and find that Slytherin has some values, like ambition in a positive sense, that she can really embrace. And there could be a plot where she has to use her new - found Slytherin knowledge to save Hogwarts from a threat that Gryffindor - centered magic couldn't handle.
One interesting plot twist could be that Hermione, as a Gryffindor in the original series, starts to question the values of her own house because of her newfound admiration for Slytherin. Maybe she discovers a long - lost family connection to a Slytherin family, which makes her more empathetic towards their ways. Another could be that she uses Slytherin - like cunning to solve a problem that Gryffindor bravado couldn't handle, causing a rift between her and some of her Gryffindor friends.
Well, a really interesting plot twist could be Hermione's role in the Slytherin house. She could become a leader, using her intelligence to reform the house's more negative aspects. Or, she might be caught in the middle of a power struggle between different Slytherin factions. Also, her interactions with the Slytherin pure - blood families could be full of drama. Maybe she discovers a family secret that could change the whole wizarding world.
In these fanfictions, Hermione's character often develops a more nuanced view of the wizarding world. She no longer sees things in the simple black - and - white way of Gryffindor vs Slytherin. She realizes that Slytherin has its own merits. So she becomes more open - minded and less judgmental. She also might develop a more complex social network, befriending Slytherins who have different outlooks from her old Gryffindor friends.
A possible plot twist could be that Hermione is a half - veela. This is not related to being a Muggleborn at all. The fanfiction could show how her veela heritage affects her magic and her relationships at Hogwarts. For example, it might make her more alluring and powerful in certain types of magic, like charms. This would completely change the way her character is typically portrayed in the original stories where she was thought to be a Muggleborn.
One interesting plot twist could be that Hermione's real family is a powerful wizarding dynasty in hiding. For example, they might have been in hiding from a dark wizard who was after their unique magical abilities. Another could be that she was adopted to protect her from a prophecy related to her future powers. Maybe she discovers that she has a connection to an ancient magical artifact that only her real family knew about, and this discovery changes her whole perspective on her identity and place in the wizarding world.
Well, sometimes in these fanfictions, a plot twist is that the Prewett twins are actually under a hidden curse. Hermione, being the brilliant witch she is, has to figure out how to break it. And it turns out that the curse is related to an ancient magic that has been long forgotten. This leads to a whole adventure where they have to search for clues in the Forbidden Forest and old wizarding libraries.
One good plot twist could be that Hermione's intelligence is initially shunned in Slytherin. They value cunning more, but she uses her smarts to re - define what cunning means in the house. For example, she could outwit Draco in a series of challenges related to potions, using her book - learned knowledge in a sly way that Draco didn't expect.
One interesting plot twist could be that Harry, in joining Slytherin, discovers a long - hidden family connection to one of the prominent Slytherin families. This changes his perception of his own identity and makes him question his place in the wizarding world.
In some of these fanfictions, a great plot twist is when Hermione gets cursed and Draco has to find a way to break it. During this process, they learn more about each other's true selves. Also, it could be that Draco is under the influence of a dark spell that makes him act against Hermione, but she believes in the good in him and tries to break the spell, which deepens their bond in a very unexpected way.
One plot twist could be that there's a prophecy about a Slytherin and a Gryffindor uniting the wizarding world, which is revealed to be about Harry and Ginny. This forces them to deal with a lot of attention and expectations from the wizarding community. It also makes their relationship a focal point of a much bigger plot, with dark forces trying to stop them from fulfilling the prophecy.
