One possibility is that Harry's presence as a kitten would soften Snape's heart. Snape, who has always had a tough exterior, might find himself more vulnerable around this small and helpless creature. Harry, on the other hand, might be able to sense Snape's true nature better in this form and start to trust him more. This could create a bond that is different from their usual relationship in the original story.
Well, one possibility is that Snape could start to see Harry in a new light. Maybe he discovers Harry's hidden talents or interests during the summer. For example, Harry might show an aptitude for potions that Snape had previously overlooked.
If Snape stays at the Dursleys in fanfiction, it could lead to some interesting character interactions. Snape might have a complex relationship with Dudley. He could try to teach Dudley a lesson about bullying, using his Slytherin - like cunning. Or perhaps he'd end up having some sort of begrudging respect for Vernon Dursley's determination to keep the wizarding world out of his family's life, while at the same time finding it completely absurd. And with Petunia, there could be a whole range of emotions, from her fear of him as a wizard to a possible shared understanding of their complex feelings towards Lily Potter.
Well, one possibility is that Draco would be completely out of his element at the Dursleys'. He's used to luxury and magic, while the Dursleys' house is a non - magical and rather dull place. He might start to understand Harry's pre - Hogwarts life better. For example, he could see how Harry was treated like an outcast, which might change his view of Harry. Maybe they'd bond over their shared dislike of the Dursleys' rules and behavior towards them.
In the fanfiction, Snape might take Harry because he discovers a connection between Harry and an ancient magic that could be dangerous if misused. So, he takes Harry to a place where he can keep an eye on him and make sure the magic is not exploited by the wrong people.
In a Harry and Snape detention fanfiction, Harry might finally have a chance to understand Snape better. He could see that Snape's strictness is not just pure malice but perhaps a result of his complex past. Snape, on the other hand, could start to see Harry not just as James Potter's son, but as an individual with his own struggles. They might end up having a conversation about magic that neither expected, leading to a newfound respect for each other.
Well, one possibility is that Draco starts to see the value in the Dursleys' family structure, despite its flaws. He could form an unlikely bond with Dudley, and they might teach each other things. Draco could show Dudley some magic tricks in secret, while Dudley could introduce Draco to Muggle games like football. It could be a really interesting exploration of two different worlds colliding within the Dursleys' household.
She might drive the Dursleys crazy with her intelligence and magic knowledge. For example, she could accidentally use magic in front of them while trying to solve some household problems, which would surely shock them as they are so against magic.
In this fanfiction, Loki might start to learn about teamwork. He could form unexpected friendships with the Avengers. For example, he might bond with Thor over their shared past in a new way, now that they are both part of the Avengers group. He could also use his trickery skills to help the Avengers in their battles against other villains.
Well, in some fanfictions, Snape might start to see Harry in a different light. Maybe he begins to teach Harry some advanced potions techniques secretly during the summer. He could also grudgingly share some of his knowledge about the Dark Arts in a more controlled way, just to make sure Harry is well - equipped to face future threats.
Well, it could be that in the 'Harry and Draco apprentice with Snape' fanfiction, they end up learning a lot about the Dark Arts from Snape, not in an evil way but in a way to defend against them. Harry would be skeptical at first but then realize the importance. Draco might be more eager as he has some knowledge of the Dark Arts from his family. Snape could also teach them how to brew complex potions that are useful in both dueling and healing. There could be some rivalry between Harry and Draco in terms of who can master the skills faster, but also moments of cooperation when they face difficult tasks.
