Under the shower i thought about the life of Vernon Dursley.

The guy is just some normal British bloke. We don't know much about his background, but given his sister is breeding bull-terriers, he's probably from some lower middle class countryside family.

He falls in love with a women who is heavily traumatized because a freak genetic mutation or something gave her sister "special powers" and made her sister her parents favorite.

He doesn't get any of it, but he rolls with it, because he loves his wife. He works hard, gets in the corporate ladder and sucks it up so his wife can stay at home and raise their recently born son.

Then some freaks show up and drop his nephew on the doorstep. Turns out his sister in law and her husband have been engaged in some vigilante paramilitary group that was fighting in a secret war against a very potent terrorist. The terrorist murdered his sister in law and her husband. Somehow their little baby survived and apparently killed the terrorist. Or the head terrorist isn't really killed because of how this freak genetic stuff works, but Vernon doesn't get any of it.

The freaks who left the child only left a letter with it, saying the child will be safe at their house, but is otherwise in mortal danger as the terrorists are still out there and also the head terrorist some day somehow might return.

Despite this bringing danger to his family, Vernon takes in the child. He figures that the best thing to protect his family and the child is for the child not to be engaged in all of this freak stuff, so he tries to get it out of that cursed child. Again he doesn't really understand any of it, but weird stuff keeps happening around that child.

Because of that he develops anger issues and kind of locks the child in, which of course isn't okay, but he doesn't know what else to do. There is no government resources to help him. He doesn't know how to reach the people who dropped the child off, however they seem to keep tabs on him and his family. Again from all he understands they are involved in some paramilitary actions.

Despite all of this he remains loyal to his wife who he understands must suffer a lot from this, but they cannot seek counseling or other help as any psychiatrist would just lock them up for psychosis.

Then the boy starts going to the school for the freak kids like his parents. He starts getting involved in fights with that terrorist, who apparently is still alive, people show up at their house through the chimney, blowing half of it away, the godfather of his nephew is a wanted murderer he knew as an armed prison escapee from the news, his own son almost gets killed in an assassination attempt on his nephew involving some sort of invisible monsters and finally the leader of that paramilitary group shows up and demands them to leave their house for a while into the unknown.

The Dursley's are left alone to deal with all of these things that are way beyond their comprehension or ability. They try to do the right thing, but often fail the task. Instead of getting understanding they are considered the evil ones by everyone who seemingly understands whats going on.
