#but all the sisters kept narcissa's quidditch playing a secret bc andy was taking muggle studies

[otrtbs]

okay, here are some of my headcanons for narcissa and regulus as the black family members who know what it's like to be left behind.

narcissa is 3 years younger than bellatrix and 2 years younger than andromeda so she has to watch her sisters go off to hogwarts and is left alone for 2 years by herself.

so when regulus is sorted into slytherin and sirius has new friends in a new house and is 'leaving him behind' narcissa takes him under her wing

narcissa is a seventh year and head girl and regulus is a first year and very tiny so it's very easy for her to sneak him into hogsmeade with her

narcissa used to play quidditch and loved it with everything she had (she was a keeper if u care) until her family (and lucius) made her quit in year six so now she spends her free time coaching baby regulus and helping him with his flying since she doesn't get too

narcissa employs regulus to help her study for her N.E.W.T.S (potions is her best class) and that's how regulus discovers his love and talent for potions (she teaches him all the upper class information so he's ahead of his classmates)

regulus and narcissa are both the observant ones of their families (it's why they're both so good at quidditch and why they're seekers and keepers respectively) and that's why narcissa is the only one who notices how regulus flinches whenever sirius "acts up" at family events

narcissa uses her age and slughorn's admiration to get permission to check out books from the restricted section for regulus (under her name ofc) not at all caring that he's a first year and shouldn't be reading them. (if regulus asked for it, she would get it for him)

regulus and narcissa are both early january capricorns, their birthdays are mere days apart (in my heart this is true!!)

when narcissa graduates she gives all of her potions notes and her special lucky caldron to regulus along with her old broom (regulus uses it even though orion bought him the best broom on the market)

narcissa opens up her house to regulus summer before his fourth year and she takes him to hogsmeade and buys his school supplies (bc things are BRUTAL between sirius and walburga and regulus has to Get Away) and they talk about surviving is a balance of complying in public and rebelling in private

regulus asks how narcissa rebels in private and she tells him about alice

they both wonder if andromeda and sirius are simply surviving like they are or actually living.

voldemort gives lucius and narcissa the diary horcrux to hide, but narcissa doesn't know what it is really and winds up telling regulus about it which is what tips him off the horcruxes

regulus making a plan to tell narcissa about the horcruxes so they can figure out how many have been made and take voldemort down in secret whilst complying in public--together. but he just has to destroy the locket he found out about first.
