In divination elegance, Professor Trelawney foresees Harry’s demise by studying tealeaves and finding the representation of a Grim, a large black dog symbolizing death. In the care of magical creatures class, Hagrid introduces the students to Hippogriffs, massive, deeply dignified crosses between horses and eagles. Malfoy insults this type of beasts, Buckbeak, and is attacked. Malfoy drags out the injury in an try to have Hagrid fired and Buckbeak positioned to sleep. In Defense Against the Dark Arts, Professor Lupin leads the class in a defeat of a Boggart, which adjustments shape to seem as the viewer’s best worry. For Lupin, it will become an orb, for Ron, a spider. Harry does not have a risk to combat it.
During a Hogwarts visit to Hogsmeade, a wizard village which Harry is unable to go to because he has no permission slip, Harry has tea with Professor Lupin. Harry discovers that the purpose he wasn’t allowed to fight the Boggart changed into that Lupin had concerned that it would take the form of Voldemort. This issue catches Harry by using wonder, due to the fact Harry had been thinking even extra fearfully approximately the awful Dementors. Snape brings Lupin a steaming potion, which Lupin liquids, much to Harry’s alarm. Later that night time, Sirius Black breaks into Hogwarts and destroys the Fat Lady portrait that guards Gryffindor Tower. The college students spend the night snoozing inside the Great Hall while the lecturers search the castle. Soon afterwards, Quidditch moves into complete swing, and Gryffindor House performs against Hufflepuff.

Later, Harry learns from Lupin that the Dementors have an effect on Harry a lot due to the fact Harry’s beyond is so terrible.
During the subsequent Hogsmeade visit, from which Harry is forbidden, Fred and George Weasley give Harry the Marauder’s map, written via the mysterious quartet of Moony, Prongs, Wormtail and Padfoot. This map leads him thru a secret passageway into Hogsmeade, where he rejoins Ron and Hermione. Inside the Hogsmeade tavern, Harry overhears Cornelius Fudge discussing Sirius Black’s duty for Harry’s mother and father’ deaths, as well as for the demise of some other Hogwarts student, Peter Pettigrew, who became blown to bits, leaving simplest a finger.

The wintry weather holidays roll around. For Christmas, Harry receives a Firebolt, the most surprising racing broomstick in the global. Much to his and Ron’s dismay, Hermione reviews the broomstick to Professor McGonagall, who takes it away out of fear that it is able to have been despatched (and cursed) by Sirius Black.
After the holidays, Harry starts operating with Professor Lupin to combat Dementors with the Patronus appeal; he is moderately a hit, however nevertheless no longer absolutely assured in his potential to ward them off. Soon before the sport in opposition to Ravenclaw, Harry’s broomstick is again to him, and as Ron takes it as much as the dormitory, he discovers evidence that Scabbers has been eaten with the aid of Crookshanks. Ron is furious at Hermione. Soon afterwards, Gryffindor performs Ravenclaw in Quidditch. Harry, on his Firebolt, triumphs, prevailing the sport. Once all of the college students have long past to mattress, Sirius Black breaks into Harry’s dormitory and slashes the curtain around Ron’s mattress. Several days later, Hagrid invitations Harry and Ron over for tea and scolds them for shunning Hermione as a result of Scabbers and the Firebolt. They experience barely guilty, however now not horrible. Soon Harry, beneath his invisibility cloak, meets Ron all through a Hogsmeade ride; whilst he returns, Snape catches him and confiscates his Marauder’s Map. Lupin saves Harry from Snape’s rage, but afterwards he reprimands him significantly for risking his protection for “a bag of magic hints.” As Harry leaves Lupin’s office, he runs into Hermione, who informs him that Buckbeak’s execution date has been set. Ron, Hermione, and Harry are reconciled of their efforts to assist Hagrid. Around this time, Hermione is noticeably confused by all of her work, and in an afternoon she slaps Malfoy for picking on Hagrid and she or he quits Divination, concluding that Professor Trelawney is a super fraud. Days later, Gryffindor beats Slytherin in a dirty game of Quidditch, winning the Cup.
Exams roll round, and for the duration of Harry’s pointless Divination exam, Professor Trelawney predicts the return of Voldemort’s servant before nighttime. Ron, Hermione, and Harry protect themselves in Harry’s invisibility cloak and head off to comfort Hagrid earlier than the execution. While at his cabin, Hermione discovers Scabbers in Hagrid’s milk jug. They depart, and Buckbeak is completed. As Ron, Harry, Harry and Hermione are leaving Hagrid’s residence and reeling from the sound of the axe, the massive black dog approaches them, pounces on Ron, and drags him beneath the Whomping Willow. Harry and Hermione and Crookshanks sprint down after them; oddly, Crookshanks knows the name of the game knob to press to still the flailing tree. They flow through an underground tunnel and arrive on the Shrieking Shack. They locate that the black dog has was Sirius Black and is in a room with Ron. Harry, Ron, and Hermione control to disarm Black, and earlier than Harry can kill Black, avenging his dad and mom’ deaths, Professor Lupin enters the room and disarms him. Harry, Ron, and Hermione are aghast as Lupin and Black change a sequence of nods and embrace.
Once the three students relax enough to pay attention, Lupin and Black explain the whole thing. Lupin is a werewolf who remains tame via a unique steaming potion made for him through Snape. While Lupin became a student at Hogwarts, his high-quality friends, James Potter, Sirius Black, and Peter Pettigrew, have become animagi (humans capable of take on animal paperwork) so that they might romp the grounds with Lupin at the total moon. They explain how Snape once observed Lupin towards his transformation site in a realistic funny story set up by Sirius, and became rescued narrowly by means of James Potter. At this second, Snape well-knownshows himself from underneath Harry’s dropped invisibility cloak, but Harry, Ron, and Hermione disarm him, rendering him subconscious. Lupin and Black then explain that the real assassin of Harry’s mother and father isn’t always Black, but Peter Pettigrew, who has been presumed lifeless but actually hidden a lot of these years disguised as Scabbers. Lupin transforms Scabbers into Pettigrew, who squeals and hedges but ultimately confesses, revealing himself to be Voldemort’s servant, and Black to be harmless. They all travel lower back to Hogwarts, but on the sight of the full moon, Lupin, who has forgotten to take his controlling tonic (the steaming liquid), becomes a werewolf. Sirius Black responds with the aid of turning into the big black canine that allows you to protect Harry, Ron, and Hermione from Lupin. As Black returns from riding the werewolf into the woods, a swarm of Dementors strategies, and Black is paralyzed with fear. One of the Dementors prepares to suck the soul out of Harry, whose patronus appeal is honestly no longer robust enough. Out of someplace comes a patronus that drives the Dementors away. Harry faints.
