I don't think a hatred of Magic would override their love of their son.
Out of everything in their lives - that love is genuine.
Their ability to bullshit through cognitive dissonance second-to-none. They will apply any logic they please to explain anything.
Dudley is overweight due to intentional negligence to his health?
He is big-boned and strong.
Dudley is behind on his studies and doing poorly?
It's the schools fault.
Dudley bullies other kids?
They must be bad - Dudley is defending himself.
ā¦Dudley is a Wizard?
Then he is a special wizard. He is perhaps the only good one of the whole useless lot of them.
Chosen one. Their son, so talentedā¦!
Not like that troublemaker Harry, and his unemployed father, and all that silly nonsense.
Dudley had a PROPER upbringing and is the BEST.
I actually think Vernon would have a much easier time accepting it than Petunia. Vernon is annoyed by magical people via his wife, mainly - other than worrying Harry being weird will fuck up his socialization and career prospects.
Dudley won't fuck anything up.
Dudley is a good upstanding young man and the pride of his life.
Petunia has trauma.
Basic difficult childhood emotions of jealousy, her sister going away and being more special, whatever - petty shit⦠But then she died.
Murdered in a secret war of magic people she has no defense against - accepting her magic son might be the only way to keep her own family safe from those who might seek them out by relation - terrifying!!!
Terrifying enough that when something magic DOES attack Dudley and she almost kicks Harry out - she has a breakdown and changes her mind, because he is their only defense.
Vernon doesn't even know about that. She lies to him, keeps it simple for him - she carries that weight on her shoulders all alone.
Dudley being magic isn't enough to make her turn against her own son⦠but I do think it would be deeply upsetting for her.
To send him into the same world that killed Lily.
A world she can't follow him into.
It would certainly give Dudley even more conflicted feelings about being a Wizard.
He was already terrified of Magic... is he capable of understanding why his mother seems so⦠sad? Scared?
Would he think he is scary to his own mother?
Would he think he is about to go somewhere awful -where he will have to be exceptionally strong?
Hufflepuff might hit the nail on the head, actually.
(imo Hufflepuff is often misunderstood tho lol maybe my views on it are different)
I don't think morality or 'niceness' has any leaning on Hogwarts Houses.
Slytherin:
Slytherin isn't 'bad people house' - it's just that people with dreams they are aiming for can end up being self-serving or greedy.
Severus wasn't in Slytherin because he liked dark things - he was in Slytherin because he aimed for the stars. He would use brains and cunning to pull himself out of the hole he was born into.
Griffindor:
Griffindor values the brave - but being noble or chivalrous, even in intent� eh⦠I mean, look at Peter:
He made exceptionally brave decisions because he was a self-serving coward. He has no ambition except security in life, he has no loyalty, he has no drive for knowledge or improvement (though he is evidently quite talented at things) - but he DOES have the balls to do daring, impossible things. To seat himself amongst those who will carry him.
Hufflepuff:
Hufflepuffs are known for hard work, loyalty, justice⦠but sometimes this gets treated like 'the friendly house where people are nice and play fair and welcome everyone', when I don't think is true.
Hufflepuffs are those, but in an 'in-group' 'out-group' structure.
What they base their 'group' on is something that might be entirely unique to the individual - but they stubbornly stick by it.
Badgers aren't soft and nice. They are fierce, grumpy, strong, violent, stubborn and deeply protective of their burrows.
Ernie quickly shunned Harry in second year. He was defending someone in his 'in' group from someone 'out' of it.
The Hufflepuffs eagerly engaged with 'Potter Stinks' shenanigans in fourth year - dying down when he earned Cedric's respect.
If Hufflepuff has a clear weakness, I'd say its Tribalism.
Being able to face Harry, in the end, and tell him he is worthwhileā¦
To go against his own family and upbringingā¦
That does seem very brave. Griffindor-esque.
But the thing about loyalty is that it can seem a lot like bravery.
Choosing to act for the people you are dedicated to.
Dudley isn't an overly brave boy. He was terrified of magic, he was scared of Harry, he was a wimp when he didn't get his own way. Butā¦
He is loyal. To his family, the way of life he is raised to believe, his burrow in a world of freaks and weakness he isn't a part of.He is dedicated and hard working. He trained to be a boxer, spends all day roaming and making sure nobody can give him any cheek - dedicated to his image of someone strong, growing up in a 'might makes right' family.He takes shortcuts in things he doesn't care about⦠but when he cares about something, whether its being spoiled or boxing, he fights HARD. Bro was making himself vomit to get his own way.He has a close gang of friends with similar values.
I think he shows a lot of Hufflepuff traits, even as a young little asshole.
I'm a big believer in Alastor Moody being the most Hufflepuff to ever Huff or Puff. Hiding in his burrow, only to come out and slam people who threaten those he cares for⦠maybe his Patronus is a Badger.
Was it brave of Moody to retire and hide away in a booby-trapped Muggle house with severe paranoia for over a decade? No.
But it was loyalty. Knowing so many vengeful eyes are on him and separating himself so others weren't caught in the crossfire.
The moment he bravely stepped out of that was also due to loyalty.
(Honestly, as far as nobility comes into things - I think a Hufflepuff is more likely to do something brave for a noble cause, because a Hufflepuff is more likely to be brave for the sake of others than a Griffindor.)
So if I'm saying Hufflepuffs are brave in relation to their chosen 'in group' - who was Dudley brave for�
His family was having to flee because of a magical war they know nothing about. Harry going to be pushed out on his own.
Dudley was brave for Harry. Himself too, sure - he might have wanted to get that off of his chest.
But I think it was for Harry. Now in Dudley's 'in' group, after saving his life. Earn a Hufflepuffs loyalty - and it'll be difficult to lose.
