This Prisoner of Azkaban Detail Will Make You Feel for Peter Pettigrew

However, there is a sad detail in the Harry Potter and the Prisoner of Azkaban book that might make you feel for Pettigrew... just a little.

If you read carefully into the moment when Sirius and Lupin explained to Harry how Sirius was never, in fact, the one who betrayed Harry's parents, you'll notice it.

The book reads that Pettigrew is heard murmuring the words "fat-fetched" and "lunacy". What initially sounds like pure gibberish actually has a meaning, because Sirius can turn into a dog (and dogs play fetch), and Remus is a werewolf who is painfully dependent on the moon phase.

Some fans even suggested that there is a reason Pettigrew was saying these words exactly.

"Makes me think that's probably how they teased each other when they were friends and Peter now unthinkingly said the same words out of familiarity," Redditor Nixiesto said.

Yes, we did just make you feel sad for Peter Pettigrew. For those who are unaware of the drama, Pettigrew was part of the Hogwarts quadrumvirate named the Marauders, which included James Potter, Remus Lupin, Sirius Black, and himself.

However, Peter turned out to be not a very good friend after all. He sold James and Lily to Voldemort, but made it seem like that was something Sirius did. Pettigrew, meanwhile, turned himself into a rat and pretended to be dead for 12 years.
