One possible consequence could be that he is immediately sent to Azkaban. Since he's a known traitor, the wizarding world would want to punish him severely for his crimes, which include betraying the Potters and framing Sirius Black.
Often, Harry catches Pettigrew by using his invisibility cloak. He sneaks up on Pettigrew and then uses a stunning spell. It's a simple yet effective method that is often used in fanfictions as it plays on Harry's resourcefulness.
Definitely Hermione and Ron. Hermione would use her intelligence to analyze the situation and come up with a plan. Ron would be the more impulsive one, ready to jump into action. Sirius Black could also be involved. Since he has a history with Pettigrew, he might have some insights into Pettigrew's actions and be able to help in the search for Harry. Also, the Weasley family in general might get involved as they are close to Harry.
There might be new witches and wizards who have heard of his story. They could be either fascinated or disgusted by his past deeds. He may also run into future versions of Hogwarts professors. They would probably be very different from the ones he knew, with new teaching methods and different personalities.
Pete Enns in this context is presumably the main figure behind the act of 'telling Gods story'. He could be someone who has dedicated his life to understanding religious concepts related to God. His role might be to bridge the gap between traditional religious teachings and modern audiences. He may use his own experiences, research, and understanding to make the story of God more relatable and understandable, whether it's through writing, speaking, or other forms of communication.
One popular Christopher Pettigrew fanfic could be 'The Adventures of Christopher Pettigrew'. It might explore his character in new and exciting ways, perhaps showing his backstory or his relationships in a different light. Another could be 'Christopher Pettigrew: The Hidden Side', which could delve into aspects of his personality that were not fully explored in the original work. And there might be a fanfic titled 'Christopher Pettigrew and the Mysterious Artifact' that takes him on an adventure to discover a powerful and mysterious object.
In fanfiction, Ron Weasley is often depicted as a loyal friend. His character traits like his sense of humor and sometimes clumsy nature are explored in different ways. Peter Pettigrew, on the other hand, is a complex character. Since he was a traitor in the original story, fanfictions might delve into his motives more deeply. Some fanfictions may try to redeem him in a way, while others might show his true evil nature more vividly in new scenarios.
