Upon meeting Remus Lupin in the third Harry Potter movie, The Prisoner of Azkaban, the Trio initially perceives him as a shabby-looking, ill, and exhausted person. However, Hermione soon realizes that he is to take on the vacant Defense Against the Dark Arts post at Hogwarts, while Ron doubts his strength. Despite this, Remus proves to be a brilliant professor loved by his students, as demonstrated in his first lesson where he teaches them how to repel a Boggart using the Riddikulus charm. Although he still appears "as shabby as ever" in chapter 7 of the book, Harry Potter and the Prisoner of Azkaban, he is described as being healthier than he was on the Hogwarts Express.
Severus Snape Fills In For Remus Lupin
In the third Harry Potter movie, Professor Severus Snape replaced Remus Lupin as the Potions master, which disappointed Harry's class. When Harry asked about Lupin's absence, Snape rebuked him, saying it was not his concern. In the book chapter "Grim Defeat," Snape informed the students that Lupin was too ill to teach and proceeded to teach Werewolves instead of Hinkypunks. In the movie, Snape asked the class about the difference between a Werewolf and an Animagus, and Hermione was the only one who knew the answer. However, Snape insulted her for speaking out of turn and called her an insufferable know-all. In the end, Hermione revealed the truth about Lupin during the confrontation at the Shrieking Shack.
Animagi And Werewolves
Animagus transformation is a skill that can be learned, unlike the hereditary ability of a Metamorphmagus or the curse of Lycanthropy. However, it is a time-consuming and risky process that requires dedication and patience. In the world of Harry Potter, Animagi play a crucial role in providing comfort and safety to werewolves during their monthly transformations. The Marauders, including James Potter and Sirius Black, went through great lengths to become Animagi in order to help their friend Remus Lupin, who suffered from Lycanthropy.
After betraying Lily and James Potter to Voldemort, Peter Pettigrew sought James and Sirius' help to become an Animagus. James transformed into a stag, while Peter became a rat, and the three Marauders decided to keep Remus company during the full moon by transforming into different animals. Following his treachery, Peter transformed into his rat Animagus and lived as the Weasley family's pet, Scabbers, for twelve years until Sirius Black's escape from Azkaban exposed his true form at the Shrieking Shack, as depicted in the third Harry Potter movie.
