Regulus Black: Headcanons
the night Sirius left the house, the house had been wrecked
trails of Unforgiveable Curse could be seen in the hallway
Mother had gone somewhere, but Regulus knew she would be back soon to continue the punishment
and this time, it would be much more painful than before
Regulus watched Sirius shoving all his belonging into two large trunks
Regulus, pale and terrified, dreading the time Mother would be back, begged his brother to stay
Sirius shook his head, hugged Regulus, and dragged his feet away
when Mother finds out that Sirius ran away, she was in rage
Mother burnt his brother’s name off the tapestry and calling Sirius names he never heard
Regulus spent the rest of the night in the library, looking for a spell to repair the burnt place in the tapestry
and cursing whenever a spell failed to save his brother’s name
the next morning he woke up to a too familiar owl
he opened the letter and recognized his brother’s scribble
the letter told him that Sirius had arrived safely at the Potters, and was hoping he would come and ‘get out of that damned house’
Regulus smiled when he read it, his eyes trailed the sentence 'your brother always, Siri’
when Regulus met Sirius next September at Hogwarts, laughing and fooling around with James and Remus and Peter, he felt betrayed
he wanted to be there too
he wanted to be brave enough like his brother
he wanted to be the one laughing next to James
to be the fifth Marauder
Regulus had to listen to hours long about how Sirius is no longer a member of Black family
but out there Sirius was having the time of his life, finally free to be what he is
right before Sirius could call him over to join them, Regulus turned and stormed away
Regulus Black felt envious, anger, jealousy, and much more
but never hatred towards his brother
even after Mother engrained the state of Sirius as a disgrace of family, a blood traitor
even after his fellow Slytherin mocked him for having a Gryffindor as a brother
even after he pledged loyalty to the Dark Lord
Regulus never have a single hatred for his brother
and he was glad he did
he thought of Remus, uttering a warm ‘thank you’ when he stopped Severus from coming to the Whomping Willow
he thought of Lily, assuring him that it’s fine if you like James, I’m dating someone else, calm down
he thought of Peter, handing him a cupcake he sneaked from the kitchen one night near full moon
he thought of James, smirking when the Gryffindor managed to corner him in the library
finally, he thought of his lovely brother Sirius, who always covered him from Mother’s wrath
his last thought was about Sirius’ last letter, stating his disappointment towards him joining the Death Eater
the signature your brother always, Siri was gone, replaced by a formal Sirius Potter
