"Hey, have you guys heard? That Sirius Black, the one who originally betrayed the Potter family, was actually Peter Pettigrew. Sirius Black is a free man now."
"Your news is old. Not only do I know Black is free, but I also heard that after getting out, he acquired some kind of miraculous magical item and his strength skyrocketed. They say even Dumbledore from Hogwarts can't beat him anymore."
"Is that really true? That's unbelievable! What kind of miraculous thing could let someone locked up in Azkaban for over a decade come out and instantly become stronger than Dumbledore?"
