Sirius and John made their way to the bank, in order to get something from the vault 713. Sirius knew that it was the philosopher’s stone, whereas John was clueless, but he wanted to pick on his curiosity. Minerva and Albus had planned that John needed to prove himself as a hero and Sirius wanted John to be seen as a heroic marauder like him, James and Remus during their Hogwarts years. He had excluded Pettigrew, because Sirius had seen, when he had reviewed his memories that Pettigrew did nothing during their school time, but hid like a filthy coward behind them, in order to protect himself from the other students, who were stronger than that bastard and wanted to make him pay for his pranks. The worst was that James, Remus and Sirius protected that filthy traitor, instead of leaving him to his faith. Sirius was furious that Pettigrew used them like that, in order to be in the top hierarchy.
