The third installment of the Harry Potter series, The Prisoner of Azkaban, starts off with a bang. Harry, frustrated and angry, accidentally uses an Inflating charm on his Aunt Marge and storms out of the Dursley household. He is picked up by the Knight Bus, where he is informed that a dangerous prisoner named Sirius Black has escaped. Upon arriving at the Leaky Cauldron, Harry is advised by the Minister of Magic and an employee at the Ministry to act responsibly. Throughout the movie, tension builds as exciting and suspenseful scenes unfold, culminating in a shocking twist at the Shrieking Shack where old friends reunite. Additionally, the introduction of Professor R.J. Lupin on the Hogwarts Express adds an interesting dynamic to the story.
Remus Lupin's Ordeal
Lupin and Harry develop a close bond, particularly after Lupin pays homage to Harry's late mother, Lily Potter. Lupin describes her as a compassionate woman who saw the beauty in others, even when they couldn't see it in themselves. Despite his amiable demeanor, Lupin's words and body language suggest that he harbors a painful secret. In a pivotal scene at the Shrieking Shack, Hermione reveals that Lupin has been absent from classes because he is a werewolf. Lupin confirms her suspicions by transforming into a werewolf in front of her and her friends, as well as Black, who is wrongly accused of betraying the Potters to Lord Voldemort. In Chapter 20, "The Dementor's Kiss," Lupin transforms again when he and his companions are caught out in the open during a full moon and he has not taken his Wolfsbane potion. Black transforms into a dog to protect the group from Lupin's uncontrollable wrath.
Fenrir Greyback and Lyall Lupin
Upon the revelation of Lupin's condition, he makes the difficult decision to resign from his teaching position at Hogwarts and leave the school altogether. In the third book, Harry Potter and the Prisoner of Azkaban, Lupin is discovered by Severus Snape and subsequently outed to the Slytherin students. Despite the efforts of Professor Dumbledore to protect him, Lupin feels it is necessary to leave the school in order to ensure the safety of the students. With a heavy heart, he bids farewell to his beloved teaching position and departs Hogwarts for good.
