Not nearly enough âSirius Black makes himself at home in Privet Drive because thereâs nothing the Dursleys can do to get him to leaveâ fic out there, and itâs a crying shame.
Harry just rolling up like WHADDUP THIS IS MY EMOTIONAL SUPPORT FAMILAR HE EMOTIONALLY SUPPORTS ME BY MAULING PEOPLE WHO THREATEN ME. And Sirus dog-charades AND THIS IS MY EMOTIONAL SUPPORT COUCH YOU CAN SIT ON THE FLOOR FUCKERS. You know what else is good âDudley gets on top of how fucked up his parents are fasterâ fic, and i feel like âSirius Lives at Privet Driveâ dovetails nicely into this:
Dudley, age 14 and realizing his motherâs Loving-but-Ill-advised cooking is setting him up for some serious health problems, and that heâs tall enough to look his dad in the eye now, so his previous rationale of âIf heâs hitting Harry heâs not Hitting Meâ doesnât hold up now, and goes full Eye of The Tiger to cope.
This means Sirus gets dragged along on a lot of Parent-avoiding âWalkiesâ
So many that one evening after a fight Dudley is trying to round up Harry and Sirius for a cooldown run and Sirius groans âOh youâre big lads you can jog to the tesco on your own.â from the couch Thereâs a hot moment of silence.
âHeâs a Magic Dog.â Says Harry.
âWhat do you mean your dog is a 40-year-old man?â âWhat do you mean your Dadâs BFF?â âWhat do you mean convicted criminal?â What do you mean WIZARD HITLER WANTS YOUR HIDE??â â..Shit I gotta up my workout routine.â âYouâre not gonna punch Voldermort out Dudley.â âNot with these wimpy biceps I wonât.â
Shitâs getting increasingly tense in the house so when Ron announces they have tickets to the Quidditch World Cup Harry has to ask âHey, can Dudley come too?â
Dudley might be short on wizarding skills but one thing heâs learned at Fancy rich boy School is the art of Schmooze. They meet Corneilus Fudge and Dudley charms the hell out of him. Fudge doesnât even realize heâs not a Wizard.  Harry tries to impress upon him the âVOLDERMORTâS ALIVE WITH A CULT DIPSHITâ upon him and nearly ends up in tears before Dudley takes his arm and whispers âLet me Handle This.â
Thirty minutes later Corneilus is organizing a Task Force of Aurors.Â
âWhat the fuck do they teach you there?â asks Harry. âOh, buttering egos, Trigonometry, grift, the usual.â âWhatâs Trigonometry?â Asks Ron, walking with them on a field trip through Muggle London for Nandos. Dudleyâs Uncle âGerald Whiteâ is supervising them itâs fine. Dudley stares for a moment. âYou guys⌠are learning math, along with your Divination and Transmorfigication and whatsits, right?â There is an awkward silence. Even Sirius considers morphing back into a dog to avoid this conversation. âOh for fucks sake.â Sighs Dudley, texting Hermionie to see if she brought her Muggle textbooks along.
(She Did)
IDK what happens when the school year starts but I love the idea of âWell some snitch (Snape) might notice if Sirus is hanging around, so instead he goes with Dudley to Fancy Rich Boy School. Maybe theyâre short a teacher there and he can reccomend his friend Remus, currently out of work for reasons that arenât his faultâŚ
Yassss!
âWhatâs trigonometry?â some pureblood at the World Cup asks him. âItâs a variant of arithmancy,â says Harry, whoâs become somewhat adept at bullshitting translations between magical and muggle things when the incentive was avoiding Aunt Margeâs wrath.
Nobodyâs ever heard of trigonometry except for one elderly pureblood witch, who had heard it mentioned once back in school by a classmate who went on to become a famous name in advanced and extremely theoretical arithmancy.
Everybody loses no time in agreeing that trigonometry must be this tremendously advanced arithmancy specialization and Dudley Dursley must be an absolute arithmancy prodigy to the point where even the arithmancy buffs donât want to risk making themselves look stupid by asking him about his research.
OBVIOUSLY Dudley goes to some extremely foreign wizarding school with an advanced research program available. There canât be many of them with an advanced âtrigonometryâ program like that, so nobody asks which school it is because what if thereâs only one of them and they look stupid for not knowing about it?
Besides, Harry Potter, the Boy Who Lived, is giving him the time of day like heâs someone really important, so, yeah.
Oh, yeah, heâs definitely the type of absent-minded brilliance that forgets his wand regularly, head in the clouds with all those theorems.
Dudley actually takes up computer programming at Smeltings. He tried it out because he likes video games, and then sort of fell in love with the process, the building something up out of lines of code, the thrill of success when it works. The awestruck reactions of wizards who see a couple of his notebooks when he sits there scribbling out code on a spiralbound notebook with a ballpoint pen is almost tangible.
The ballpoints and the notebooks take some suspicion for their muggleness until Harry points out that you donât need to pay attention to how much ink is left and when you need to dip it, so itâs perfect for somebody who might want to scribble out whole pages of that stuff without noticing whether theyâve run out of ink, and the notebooks have pages so you could remember where something is. Pretty soon quill-tipped ballpoints are all the rage and spiralbound parchment stacks are being sold in all the stores.
Somebody asks Dudley about his family history. âOh, theyâve all been like me,â he says, âas far back as anybody remembersâ and he means not-a-wizard, but everybody thinks the opposite.
His father is blustery and yells and prone to explosive bursts of anger, he says, and his mother is obsessed with cleanliness and etiquette, and everyone is perfectly happy to never suggest theyâd like to meet them.
Once Dudley figures out that everyone thinks heâs a wizard, he and Harry have a solid laugh over it and Harry teaches Dudley what heâd need to know to continue the deception. Fred and George are brought into the equation and provide him with lots of cool tricks and such so that he can appear to do some small bits of magic now and again.
He eventually marries Daphne Greengrass, who knows about his muggleness at that point and loves the idea of getting one over on her overly bloodpurist parents without them ever knowing about it. Harry and Sirius quietly gift them Number Twelve, Grimmauld Place, and the assumption that Dudley has the sort of money that buys a historic Pureblood property as a starter home goes round and round.
Dudley ends up on the Board of Governors, and later Minister for Magic, and in their old age Petunia and Vernon suffer the mingled pride and fury that their son is a Government Minister and they canât brag about it.
Two other AUs this goes well with:
âall the pureblood dipshits tithed thier land and holdings to Voldemort so when Harry kills him, all the assets go to him and now he owns half of wizarding UK.â
âearly on his career as a wizard, Dudley goes to Wales to meet another Famed Arithmancer and becomes close friends with fellow videogame and rugby enthusiast Howell Jenkins.â
