The Black Siblings

Regulus always feared the day that Sirius would go too far, the day that Walburga and Orion would finally have enough of his rebellion and disown Sirius and pass the title of heir onto Regulus.

Because while Sirius was loud and brash about his disregards for the family traditions, Regulus was as quiet and observant as always. But that didn’t mean that Regulus was in accordance to the Black’s family values, not at all.

Because Regulus - aromantic, asexual, agender Regulus - wasn’t in favour of those stupid values that bred so much insanity, homophobia and transphobia. No. They rather wanted nothing to do with it, but they weren’t as brave as their brother in showing it. Too afraid of the repercussions to act out for nothing.

The day Sirius got disowned - for dating a half-bloodman(Regulus had figured out that Remus Lupin was far more than just a man in their second year, but never told Remus’ secret to anyone) - was the day Regulus knew their life was about to drastically change.

All the expectations their parents had previously placed on Sirius (marrying a pureblood girl, providing an heir, going into politics) were now placed on them and THEY DIDN’T WANT ANY OF IT.

At 17, the constant misgendering and the marriage contract negotiations finally pushed them over the edge and they left Grimmauld Place in the middle of the night. With no plan where to go, no possession other than the clothes on their body and the wand in their pocket, and no hope in their heart.

Rumours of Regulus’ disappearance traveled fast and by noon the next day there were people out looking for them.

Luckily, Sirius found them first, sitting in a muggle park near one of the houses they had spent a few weeks in, when they were kids. Regulus wasn’t surprised when the black dog transformed into their brother. They simply nodded and continued staring blankly onto the small lake.

The siblings stayed on the rusty bench for nearly 4 hours before Regulus admitted to Sirius why they had left. Sirius simply hugged them, telling them that he still loved them no matter what and asked whether they would want to come live with him?

Regulus was super grateful and accepted their brother’s help, although they promised to be gone as soon as they had found a job. When Sirius carefully mentioned that Remus was also living with him, Regulus managed to shock him profusely, when they only answered that “as long as he isn’t in the house during the transformations” they would be fine with it.

Regulus lived with wolfstar for almost a year before they moved into a dorm closer to their campus. The former Black siblings still met up every friday night for pizza and games, years after Regulus had finished university.
