The plot could start with Draco trying to humiliate Hermione in front of other students. He might try to steal her books or sabotage her potions. Snape saves her when he witnesses Draco going too far. Snape might be aware that Hermione is crucial to the balance in Hogwarts. He doesn't want Draco's actions to lead to chaos. So, he steps in and stops Draco, warning him about the consequences of his actions. And this event could be a turning point in the fanfiction, making Hermione more cautious around Draco and more curious about Snape's motives.
In the fanfiction, Draco's abuse of Hermione could be a result of his jealousy. Hermione is always top of the class, and Draco can't stand it. He starts with small pranks like jinxing her quill during exams. Snape, on the other hand, saves her because he realizes that Hermione is a valuable asset to Hogwarts. He might also have a soft spot for her because she reminds him of Lily in some ways. After Snape saves her, Hermione might start to view Snape in a new light, and Draco might face some sort of punishment or come to realize the error of his ways.
Well, it could be that Draco, in his pure - blood pride and influenced by his family's views, targets Hermione. Maybe he uses some dark magic or just plain bullying. Snape, despite his often cold exterior, might save her because he secretly admires Hermione's intelligence or perhaps he has a deeper reason related to his own past with the Gryffindors or his hidden loyalties. For example, he could see a bit of himself in Hermione's determination to succeed in a world that is often against her.
Snape would probably be very stern with Draco. He might give him a severe scolding and deduct points from Slytherin. Snape is a strict teacher and he won't tolerate such behavior from his own house students.
One reason could be Snape's sense of justice. Despite his often - cold exterior, he might not tolerate Draco's bullying behavior towards Hermione.
Well, perhaps Snape uses his position as a teacher to step in. He could have been observing the situation secretly and when Draco was about to do something harmful to Hermione, Snape intervened with a firm command or some magic spell to stop Draco in his tracks.
Some fanfiction writers might do it for shock value. They want to create a very different and extreme situation compared to the original story to attract readers' attention.
One possible reason could be that Snape sees Hermione's value as a brilliant student. He might recognize her potential and not want it to be wasted just because of her dad's actions or situation. Maybe he has a sense of justice deep down, despite his often cold exterior.
Perhaps Draco saves Hermione in a very public and unexpected way. This could lead to a huge scandal in the wizarding world. Lucius might be shamed and lose a lot of his influence among the Death Eaters. Draco, on the other hand, might find himself an outcast among his own family and former friends. Hermione, feeling indebted to Draco, might try to protect him from the backlash, which could further develop their relationship in an interesting way. It could also be that Draco's act of saving Hermione is part of a prophecy that neither of them knew about. This could add a layer of mystery and destiny to their story.
Draco might be motivated by jealousy. He could be jealous of Ron and Hermione's friendship or a possible romantic relationship between them. So he tries to harm Hermione out of spite.
The plot could start with Hermione being in a dangerous situation near water, like she might be attacked by a water - based dark creature while near a lake at Hogwarts. Draco, who might be nearby for some reason, overcomes his initial hesitations (due to their past enmity) and jumps in to save her. After that, they could start to see each other in a new light, leading to a slow - burn relationship as they deal with the aftermath of the incident and the reactions of their friends and the Hogwarts community.
In fanfiction, such a plot is often a deviation from the original spirit of the 'Harry Potter' series. J.K. Rowling's original works do not have such a relationship. Fanfiction sometimes creates extreme or untrue scenarios for the sake of creating drama or exploring different relationships. So, in the context of the official story, it's not true.
Well, in some versions, Snape might use his magic skills and authority within Hogwarts. He could place protective spells around Hermione or keep a watchful eye on her movements, ensuring Draco can't get close to her without his knowledge.
