Although Peter was an insignificant little character in the original text, he changed the fate of many people. His betrayal killed the Potter family, causing the werewolf and the Big Dog Godfather to part ways. Snape completely bore the cross that killed Lily. Voldemort's resurrection and Harry's narrow escape from death among the Death Eaters were also inseparable from his shadow. So small people change big destiny.
What kind of butterfly effect would it have if a person who had no idea about the plot dressed up as Peter Pedro in HP? Where will the destiny trajectory that has been changed unknowingly go?
The cp has not yet been determined, but it will never be allocated to professors.
