Summary
In the aftermath of the prank, Remus decides to get revenge by pretending to be friends with Regulus while James pretends to date him. Regulus on the other hand goes with it for his own selfish purposes.
Sirius however is left to suffer the consequences of not just his friends befriending his little brother but the knowledge that Regulus did it solely because Sirius refuses to bow down to their mother's wishes.
He isn't content to suffer for much longer however and let's face it. Sirius was always better at revenge.

Summary
Sirius Black dies falling through the Veil… and wakes up in his childhood bed.
He's five years old again, trapped inside the cold, ancestral prison of Grimmauld Place, surrounded by ghosts who haven't died yet—his cruel parents, a brother too young to betray him, and a bloodline that expects obedience. But Sirius remembers everything.
The war. Azkaban. James and Lily's deaths. Harry’s screams.
Now, with nothing but memory and fury, Sirius must survive pureblood society all over again—and dismantle it from the inside. As Walburga prepares her sons to carry the Black legacy, Sirius quietly lays traps beneath it. At Hogwarts, he forges old friendships anew, carefully watching for the first cracks in the future’s foundation.
But fate doesn’t yield easily. Time resists change. And some stars are meant to burn out.
This time, Sirius won’t go quietly.
This time, the House of Black will learn what happens when a star refuses to fall. -

Summary
As he reached the Tower, he looked at the clear night, he could see all of his family there. He could see Bellatrix, Andromeda, Sirius, Orion and Regulus. In the sky, Sirius and Andy wouldn't be fighting the rest of the Family, Bella wouldn't be a fanatic and Orion wouldn't be indifferent. In the skies his family would be together.
He took out his knife and exhaled heavily. This was it. This was what he had been waiting for, for weeks. He put the tip of the knife near his wrist, and dragged it upwards.
