They might be horrified. The Dursleys are very set in their Muggle ways, and magic is completely foreign to them. So, seeing the Potters, who are clearly magical, could terrify them.
It's also possible that the Dursleys are intrigued despite themselves. The allure of the unknown, which magic represents to them, might make them want to learn more, even if they are initially reluctant.
In fanfiction, when the Potters meet the Dursleys, there could be a lot of tension. The Potters are magical and the Dursleys are muggles who despise anything out of the ordinary. There might be arguments as the Potters try to understand why the Dursleys have been so cruel to Harry. Or perhaps there could be a moment of redemption for the Dursleys as they see the good in the Potters and realize their mistakes in treating Harry so badly.
In fanfiction, when the Dursleys meet the Potters, there could be a lot of tension. The Dursleys are so ordinary and Muggle - centered, while the Potters are a wizarding family. The Dursleys might be initially shocked and scared by the magical elements the Potters bring. Maybe they'll see a wand for the first time and react with disbelief or even horror. It could also lead to some comical situations, like Mr. Dursley trying to rationalize the magic away as some sort of trickery.
The Potters are often depicted as kind, brave and magical - loving in fanfiction. In contrast, the Dursleys are narrow - minded, self - centered and prejudiced against magic. So when they meet, the Potters' open - mindedness clashes with the Dursleys' close - mindedness. The Dursleys might be rude and dismissive, while the Potters try to be friendly and inclusive.
For the Weasleys, they could be excited to meet Hermione's parents. Arthur Weasley might be especially interested in learning about muggle things from the Grangers. The Grangers may be a bit overwhelmed by the Weasleys' boisterous nature and the presence of magic, but they would also be glad to see the family their daughter is so close to. They might start to relax as they see how kind and inclusive the Weasleys are.
The Dursleys are a rather uptight and narrow - minded family. In this fanfiction scenario, they could be extremely judgmental of Harry's girlfriend. They might look down on her if she doesn't fit their idea of what a proper person should be like. They may also be secretly afraid that she will expose their mistreatment of Harry, so they could act very defensively during her visit.
At first, Bellamy might feel a bit of anger. Maybe he's been through some tough situations on the Ark and blames Clarke for not being there. But as they start talking, that anger could turn into understanding. Clarke could explain her side of things, and they could start to rebuild their friendship. And then, they might both feel a new sense of hope, knowing that together they are stronger and can face whatever challenges the Ark has to offer.
Well, in some fanfictions, the Dursleys might be completely bewildered when they meet Teddy. Teddy, being a wizard like Harry, could show off some magic accidentally, which would terrify the Dursleys as they are so used to the non - magical world and have always been afraid of magic.
In some fanfictions, when the Dursleys meet Sirius, there could be a lot of chaos. Sirius, being a wizard, might shock the Dursleys with his magical abilities. They would probably be terrified and try to get away from him as they are not used to magic. Maybe Sirius would try to take Harry away from them right then and there, leading to a big confrontation.
In fanfiction, when the Grangers meet the Dursleys, there could be a clash of values. The Grangers, being Hermione's intelligent and kind - hearted Muggle parents, might be appalled by the Dursleys' treatment of Harry. They could try to set things right, perhaps by confronting the Dursleys about their neglect and abuse of Harry. This might lead to a series of tense exchanges as the Dursleys are not used to being challenged, especially by Muggles.
Mr. and Mrs. Granger might be curious. They've heard so much about the wizarding world from Hermione, and Draco is a big part of that world. So they may ask him a lot of questions right away.
