Fanfiction often takes liberties with the established canon. Regarding Hermione being Pansy's sister, it could be due to a hidden blood relation. There might have been a secret affair or a long - lost family member that links them. This new relationship would completely change how they interact with each other and with other characters in the Harry Potter world. It could lead to some really unique scenarios, like Hermione having to deal with Pansy's Slytherin friends or Pansy being influenced by Hermione's Gryffindor values.
Well, in fanfiction, anything can happen. It could be that a spell or some magical accident in the past led to Hermione and Pansy being sisters. Maybe a time - traveling wizard messed with the past, causing their family trees to merge in a way that made them related. It's a really interesting concept that allows for a whole new set of character dynamics and storylines to be explored.
Well, in fanfiction, anything can be made possible. Maybe a long - lost family connection was revealed. It could be that there was some sort of secret adoption or a hidden family tree branch that ties them together. Writers of fanfiction often take creative liberties to explore such unique relationships that were not part of the original story.
Well, in fanfiction authors often take creative liberties. It could be part of an alternate universe scenario. For example, if there was a different timeline where the wizarding families were arranged differently. Hermione might have been adopted into the Black family (Narcissa's family) through some complex set of circumstances, like a deal between two powerful wizards to protect her from some dark force.
It could be due to a time - travel related plot. Perhaps Hermione goes back in time and through some unforeseen circumstances, her family line gets intertwined with Sirius' family, making her his sister in an alternate timeline. This could involve her interfering with past events that change family structures.
Well, in fanfiction, the author has the liberty to play with the lore. There could be a scenario where a powerful dark magic spell in the past had some unforeseen consequences. This spell could have somehow intertwined the bloodlines of Voldemort and Hermione's family. Maybe a curse was placed on a family that later branched out to both Voldemort and Hermione's ancestors, creating this strange connection.
Well, in fanfiction, some authors might come up with the idea that there was some hidden connection or a secret affair in the past. Perhaps Voldemort had a relationship with Hermione's mother before he fully embraced the dark side. This would completely change the dynamics of Hermione's character and her place in the wizarding world. It could lead to her having to deal with the stigma of being related to the most evil wizard ever while still trying to uphold her values.
In fanfiction, the idea of Hermione being Draco's mother can be made possible through alternate timelines or magical interventions. For example, a powerful spell could have altered their family relationships. It allows writers to explore different character dynamics and how it would change the story.
Well, in fanfiction, the idea of Hermione being Voldemort's niece might stem from some sort of magical tampering with family lines in the past. It could be that a powerful spell was cast long ago that altered the relationships in a way that made Hermione related to Voldemort. Or it could be a completely different take on the lore where the wizarding world has a whole other layer of hidden family connections that JK Rowling didn't explore in the original series.
Well, in fanfiction, the author has the freedom to twist the original story. For McGonagall to be Hermione's mother, perhaps there was a powerful charm placed on Hermione as a baby to hide her true parentage. And McGonagall, being a powerful witch, had reasons to keep this a secret, like protecting Hermione from some dark forces that were after her because of her heritage.
In fanfiction, anything can be possible. Writers often bend the rules of the original universe. Maybe it could be through some sort of time - travel magic that Hermione goes back in time and meets Salazar. Or perhaps there's a magical spell that binds their fates together in an alternate reality created by the fanfic writer.
One possibility could be through a powerful and misfired spell. Maybe a spell that was intended for something else, like a transfiguration gone wrong during a complex magic experiment in Hogwarts. For example, if a spell was being tested to enhance learning abilities by temporarily taking on the mental characteristics of a top student, it could have accidentally caused a full physical and mental transformation into Hermione.
