Although Sirius was not skilled at using Mental Magic, he could still sense from Vizet's words how much insight Vizet had into Mental Magic.
No wonder Dumbledore had been sitting there the whole time, not acting himself, but letting Vizet do it for him.
"In other words, I just need to relax and try not to resist your magic..." Sirius asked. "That should do it... right?"
"Yes, Mr. Black." Vizet nodded and raised the Wand in his hand.
"Or... you could just call me Sirius?" Sirius suggested. "That's what Harry and the others call me. Being addressed so formally actually makes me a little uncomfortable."
"All right, Sirius," Vizet replied, pressing the Wand against Sirius's temple.
"Based on past experience, you shouldn't feel anything... If you think there's no problem, then we'll begin!"
"Oh! Of course!" Sirius nodded, let out a long breath, and half-closed his eyes as if adjusting himself. "Go ahead!"
Relying on the keyword "Peter Pettigrew," Vizet pried open the memory with ease;
However, the memories related to "Peter Pettigrew" could be traced all the way back to the beginning of school;
Vizet merely gave them a quick glance to make sure they did not contain the information he needed, then quickly moved on, continuing to search for memories related to Azkaban...
Starting from the time Voldemort fell ten years ago, Sirius, because of his special circumstances, had been caught red-handed by Cornelius Fudge, and should have been among the first people imprisoned in Azkaban;
He remained silent in Azkaban. No matter who requested to visit him, he refused with a firm shake of his head, giving Vizet the feeling that he was exiling himself.
Time passed in the memory, and more and more prisoners entered Azkaban, until a young man was also escorted into Azkaban.
