As the group leaves the Shrieking Shack and returns to the Whomping Willow, Black confesses that he is Harry’s godfather. He realizes that turning Pettigrew in will make him a free man, and he offers to let Harry stay with him instead of the Dursleys. Harry eagerly accepts, and Harry sees a smile in “Black’s gaunt face” (379) for the first time. However, the night is suddenly bathed in moonlight, and at the sight of the full moon, Hermione remembers that Lupin “didn’t take his potion tonight! He’s not safe!” (380).
As Lupin transforms into a werewolf, chaos breaks out. Peter Pettigrew breaks free, knocks Ron unconscious, and escapes into the night. Sirius tries to protect the others by transforming into a dog and fighting Lupin, but he is badly injured, and Lupin flees into the forest. Harry and Hermione find that Sirius has transformed back into a man, and there are over a hundred dementors closing in on him. Harry and Hermione try to use the Patronus Charm, but they aren’t strong enough, and the dementors close in on them, preparing to deliver the Dementor’s Kiss. Suddenly, “a silvery light [grows] brighter and brighter” (384), eventually driving the dementors away. Across the lake, Harry sees a Patronus and someone who looks strangely familiar before he faints.
Harry wakes up in the hospital wing with Hermione and Ron. Ron is still unconscious. Harry hears Snape and Fudge discussing what happened, and he learns that Black has been apprehended by the Ministry of Magic. The hospital wing matron, Madam Pomfrey, tells Harry that “the dementors will be performing the kiss any moment now” (389). Harry and Hermione rush to tell Fudge that Black is innocent, and they’ve got the wrong man. Snape and Fudge dismiss their claims, but Dumbledore arrives and asks to speak to Harry and Hermione in private. Dumbledore believes their story, and Black told him the same thing, but “Professor Snape’s version of events is far more convincing than [Harry and Hermione’s]” (392). Dumbledore then turns to Hermione and tells her that “three turns should do it” (393), and that they must not be seen. He locks them in the hospital wing, and Hermione shows Harry a “tiny, sparkling hourglass” (394) around her neck.
Hermione turns the hourglass, and they are transported three hours back in time. The device, called a Time-Turner, was given to Hermione at the beginning of the school year so she could attend multiple classes at once. They first rescue Buckbeak from being executed, and as they wait for the events at the Whomping Willow and the Shrieking Shack to unfold, Harry confesses to Hermione that although it’s ridiculous and impossible, he believes his father conjured the Patronus that saved them from the dementors. When the moment comes for Harry’s father to rescue him, Hermione, and Sirius from the dementors, Harry realizes that no one is coming, and he must be the one to rescue their past selves. He conjures an incredibly powerful Patronus, and the dementors retreat. Harry realizes that his Patronus has taken the form of a stag, the animal his father could transform into as an Animagus. Harry and Hermione ride Buckbeak up to the part of the castle where Sirius is being held, and they give him the hippogriff to escape with. Sirius says his goodbyes, then disappears into the night with Buckbeak.
Harry and Hermione sneak back into the hospital wing as Dumbledore is locking them in. Snape and Fudge are furious to learn that Black has mysteriously disappeared, and Snape claims “THEY HELPED HIM ESCAPE, I KNOW IT!” (419). Fudge promises that the dementors will be sent back to Azkaban because they attempted the Dementor’s Kiss on Harry, an innocent boy. Ron awakens, and Harry and Hermione explain everything that happened. Lupin tells Harry that Snape “accidentally let slip that [Lupin is] a werewolf” (423), so Lupin decided to resign before word reaches the parents of the Hogwarts students: “They will not want a werewolf teaching their children” (423). He returns the Invisibility Cloak and the Marauder’s Map to Harry and bids him goodbye. Dumbledore assures Harry that he did the right thing in showing mercy to Peter Pettigrew, and he confirms that Professor Trelawney did have a real prediction the previous day: Voldemort will likely rise again, and Pettigrew will help him. Dumbledore suggests that although Harry didn’t see his father that night at the lake, “[Harry’s] father is alive in [him]” (427).
Hermione gives the Time-Turner back to McGonagall and decides to stick to a more manageable schedule in the future. Harry is disappointed that he won’t be able to go live with Sirius now, but on the train ride back home for the summer, Sirius sends a letter with a tiny owl. Sirius assures Harry that he and Buckbeak are safe, and he confesses that he sent Happy the Firebolt. He also confirms that he was the dog Harry saw last summer. Sirius provides written permission for Harry to go into Hogsmeade next year, and he offers the owl to Ron, “as it’s [Sirius’s] fault he no longer has a rat” (434). When Uncle Vernon picks Harry up at the train station, Harry decides to let it slip that he has a godfather who is “a convicted murderer, but he’s broken out of wizard prison and he’s on the run” (435), adding that Sirius likes to check in on Harry and make sure he’s happy. Uncle Vernon is horrified, and Harry is hopeful that this summer will be better than the last one.
The final chapters of The Prisoner of Azkaban provide a few more dramatic twists in the plot. Just when it seems like Sirius is set to become a free man, disaster strikes. Lupin unexpectedly transforms into his werewolf form, and Pettigrew escapes. Everything seems to go wrong at once, and when the dementors close in at the end of Chapter 20, Harry feels more powerless than ever as his Patronus fails to form. As a child, Harry has had little control over his own life, and in this terrifying moment he is once again at the mercy of someone coming to help him. Of course, the surprising twist at the end of Chapter 21 reveals that Harry was the one who rescued himself from the dementors. Overwhelmed by the knowledge that he is capable of this level of strength empowers Harry, and his Patronus is potent enough to drive away the dementors. Harry, who never had a chance to have a relationship with his father, feels more connected to him than ever before, and Dumbledore helps Harry see that a part of his father’s spirit will always live in him.
The mystery of Hermione’s bizarre behavior is finally resolved in the final chapters. Because of Hermione’s impressive record as a model student, she is granted more responsibility with the Time-Turner and a heavier schedule. However, Hermione begins to break under the pressure of this school year. She realizes that there can be freedom in rebellion, and just like Harry is transitioning into his teenage years, Hermione, too, tests the waters of noble disobedience. She slaps Malfoy for disrespecting Hagrid, storms out of Divination when she feels disrespected, and finally she is willing to break her promise to only use the Time-Turner for academic purposes. Hermione is beginning to understand that rule-following is not always morally right, and what is morally right may not always involve following the rules.
Professor Lupin’s resignation touches on an unfortunate trend in the real world: Despite how gifted, kind, or effective a person might be, prejudice takes many forms and can often sabotage their life. Lupin has faced prejudice before, which is why he chooses to resign as soon as word gets out that he is a werewolf. Lupin’s status as a werewolf has led to countless obstacles throughout his life, and although he has never hurt anyone before, he recognizes that he has the potential to hurt his students, and he has a strong sense of personal responsibility for his own behavior. In this way, Lupin serves as a role model to Harry and demonstrates what it means to put the well-being of others above his own wants.
