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.
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.
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.
One possibility is that Draco, being from a pure - blood wizarding family, could try to 'educate' the Dursleys on the wizarding world. He might brag about his family's wealth and status, which could lead to some comical situations. The Dursleys, on the other hand, might be completely unimpressed and tell Draco off, which would be a new experience for him as he's used to being fawned over in the wizarding world.
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, in such a fanfiction, Draco might be completely out of his element when he meets the Dursleys. He could be shocked by their rudeness and lack of magic knowledge. Maybe he'd initially look down on them but then gradually realize there's more to them than meets the eye.
It's possible that Draco would initially not believe what he hears about the Dursleys. But as he digs deeper, he realizes the truth. He might then face a moral dilemma. On one hand, he has been taught to look down on Muggles like the Dursleys. But on the other hand, their behavior towards Harry is clearly wrong. This internal struggle could be a major part of the fanfiction, and it could lead to his character development in unexpected ways.
Draco would surely interact with the Dursleys. Vernon would probably be very suspicious and hostile towards Draco at first, seeing him as another strange and magical being. Petunia might be a bit more reserved but also curious in her own way. Dudley could range from being intimidated by Draco's wizarding background to being fascinated. And don't forget about Hedwig! If she's still around, Draco might have some sort of interaction with the owl, which could be really funny or interesting as he tries to figure out how to deal with this magical creature in the Muggle - dominated Dursleys' household.
It could be part of a plot where Draco is given an assignment by someone in the wizarding world to save Harry from the Dursleys. He initially does it for self - serving reasons like getting in good with certain powerful wizards who are concerned about Harry's well - being. But during the process, he actually starts to care about Harry.
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.
Perhaps Snape would initially mistake the Dursleys for some sort of Muggles with a bit of dark magic in them due to their cruel nature. He could start investigating them, which would cause chaos in the Dursley household as they try to hide their secrets from a wizard like Snape.
