hogwarts au!

send me an au and i’ll give you 5+ headcanons about it

it has been so long since i have read a harry potter….

cosima is a ravenclaw.  she likes knowledge for the sake of knowledge.  why does she need to know about the history of the eye of newt in potions?  just because.  she can be a little tunnel vision, laser focus on things if they interest her.  she has a lot of friends across the houses, though.  her wit and charm win people over and she’s pretty well liked.

shay is a….. hufflepuff?  no.. gryffindor… no…. i ……… see. the problem with shay is that she is really brave and strong.  she values courage and nerve.  but then she’s hardworking and loyal.  she’ll throw down and fight but only it’s for her loved ones or it’s the right thing.  actually, i think i just convinced myself that shay is a hufflepuff.  she’s less of a ‘hold my beer kind of brave’ she’s a ‘needs to do the right thing’ kind of brave.  she’s on the quidditch team, on track to become a prefect and head girl. everybody loves her.

delphine is a slytherin.  but she’s french, so a transfer student?  she went to beauxbatons for a while and they wouldn’t let her skip grades or anything so her dad transferred her.  she read up on hogwarts houses meticulously to see which would be the best to slide into unnoticed and wanted more than anything to get into ravenclaw. she then tried to lie to the hat, which was a very slytherin thing to do.  she’s miserable.  she’s homesick.  the other kids tease her.  she spends most of her time in the library.

this got really long so the rest is under this cut.

enter cosima.  they’re studying near each other for weeks before cosima looks up and, like, notices her.  then she notices that she gets picked on a lot and tries to make friends (she hears her crying in one of the furthest back stacks and pretends to believe delphine’s ‘it’s the dust’ before shaking hands and introducing herself).  and it’s hard.  delphine is a tough nut to crack, she’s shy and self-conscious and wary.  but eventually she gets her talking about potions or wand motions or the evolution of spell names and she’s just… smitten.  delphine is as well, she’s never had someone want to talk to her about this nerdy stuff.  she’s never met anyone who likes to talk geeky and enjoys delphine as a person.  she might have a little bit of a crush.

but.. the other, awful slytherins find out.  you know the ones.. the stereotypical, xenophobic, bully slytherins.  and that’s the last straw for them.  they know that she’s lethal with a wand, even though she’d never use a deadly curse.  so they ambush her in the hallway when her wand is tucked in her bag.  she ends up toppling down the stairs trying to get away from them and cracks her head open.  in a daze, she watches as shay steps around the corner and gets the other kids to leave her alone.  she’s just as scary with a wand and she’s a beater for the quidditch team.  she all but carries delphine to the hospital wing.

she gets delphine to open up about what happened even though mrs. s (who is madam pomfrey.  or wait. is she mcgonagall.  :/ ) couldn’t.  shay reassures her that being gay is a-okay, that she herself is gay.  she comforts delphine as well as a 14-15 year old can comfort someone in that situation.  she leaves with a, ‘if you ever need anything, you can come and find me.  you know where the hufflepuff dorm is, right?’

the next time she’s in the library, cosima is all over her.  ‘i heard what happened, are you okay, do you want me to beat anyone up, cuz i will.’  she doesn’t know that they were beating her up for being in bi love with cosima, which is a relief but also a disappointment.  they fall back into their routine, but cosima spends a lot more time in the library.  she starts to invite delphine to things, little outings to hogsmeade or to hang out in the ravenclaw dorm.  most of the time she says no.  but when she says yes they have a great time.

shay starts to hang out in the library, for exam purposes.  she’s falling behind in history of magic, that’s the only reason why do you ask?  it’s not that she feels really protective of this gangly nerd she saved the other day, why would you think that?  she hovers near delphine and cosima until cosima, who knows her from class and bc she’s the equivalent of a celebrity at the school, invites her over.  they become really, really close friends.  just. gals being pals.  who are also highkey in love with each other.  they’re just confused about what it is because they have two equally as powerful crushes?  and don’t know what to do with that?  because?  you can’t date two people?

the summer before sixth year cosima writes them both extremely excited letters.  she was reading some muggle queer books and there’s this concept of polyamory!! and she’s so excited and asks if they could maybe try it?  cuz she likes them both.  shay writes back with an enthusiastic yes.  delphine as well.  the first thing they do when they see each other and they’re alone is pounce on each other and try to figure out kissing, like in general but also when there’s three people.

cosima sends them both howlers that scream “I LOVE YOU” on a regular basis, delphine is Mortified and shay stands on the table to scream it back.

some little first year is In Love with delphine.  she feels bad but like, wants to be rid of him.  so shay walks up to her, plants a big ol kiss on her, and pulls her away by her tie.  he still follows her around, but it’s more of an academic venture than anything.

cosima is really into the Look of the tie and the button up shirts, but has to accessorize her own to be unique.  delphine pulls it off really well, just wearing the uniform like she’s supposed to.  shay is not thrilled about wearing them, but she likes how it looks on other people.  she wears her regular clothes at every possible opportunity.

delphine loves the great lake.  something about it is just so soothing to her.  it is not advisable to swim in it, bc of the temperature and the creatures, but she wades in at every opportunity.  cosima goes in with her and promises that if she ever gets to san francisco she’ll teach her how to surf.  but right now her toes are numb, so she’s going to get out for a minute.

cosima and delphine sit in the hufflepuff stands for quidditch games, much to the other hufflepuffs surprise.  delphine will wear yellow, she does not give a single fuck about slytherin.  cosima can’t get herself to do it, but she doesn’t wear blue which is something.  shay becomes a little bit of a showboat when she knows where they’re sitting.

oh wait fuck… shay and cosima are both american… exchange program??  the american school got shut down bc of like.. the appropriation??

this was way more than five but…
