Highlights
Hagrid's return to Hogwarts is celebrated by everyone except Draco and a few Slytherins, highlighting his importance to the school community.
Draco's insult towards Hermione exposes his adherence to pure-blood supremacy, whereas Hagrid confronts these biases and commends Hermione for her exceptional abilities.
Hagrid fell victim to false accusations and was framed by Tom Riddle for releasing the horrors of the Chamber of Secrets, resulting in his expulsion from Hogwarts and subsequent incarceration in Azkaban.
In the ending of Harry Potter and the Chamber of Secrets, Dumbledore requests Azkaban to release Rubeus Hagrid, the gamekeeper of Hogwarts. Upon his return, Ron, Hermione, Dumbledore, and Harry, along with most of the students, express their joy, while Draco Malfoy and a few Slytherins remain unimpressed. Hagrid enters the Great Hall to applause and cheers from the students, who have just received the news that all exams have been canceled. Apologizing for his lateness, Hagrid makes his way towards the Golden Trio and expresses his gratitude for their help in securing his freedom. Ron and Hermione smile at him, and Harry embraces him, acknowledging Hagrid's crucial role in Hogwarts. Despite the warm welcome upon his return, questions still remain about why Hagrid was initially imprisoned in Azkaban.
Draco Insults Hermione
Draco, influenced by his father Lucius, fully embraces the ideology of pure-blood supremacy, as depicted in The Chamber of Secrets. At the start of the film, he reveals himself as the new Seeker for Slytherin and, when Hermione mocks his way of obtaining the position, he retaliates by labeling her a "filthy little Mudblood." As the intellectual powerhouse of the Trio, Hermione is well aware that the term "Mudblood" is a highly offensive insult directed towards witches or wizards who are born to non-magical parents. In essence, it signifies having impure or "dirty" blood—a derogatory term specifically used to demean individuals like herself.
Hagrid also sheds light on the growing polarization that has caused divisions among young minds. He points out that certain families, such as the Malfoys, possess a superiority complex, believing themselves to be superior due to their "pure-blood" status. However, Hagrid reveals to Harry that there are no witches or wizards who are not of mixed blood. He dismisses the idea of pure-blood supremacy as nonsense. Ultimately, Hagrid commends Hermione's abilities and advises her not to waste her time thinking about Draco Malfoy.
"Don't dwell on it, Hermione. Not even for a moment. Got it?"
Thus, in The Chamber of Secrets, Hagrid proves that he is the exact kind of mentor that Dumbledore would want around students of Hogwarts.
The Re-opening Of The Chamber Of Secrets
In The Chamber of Secrets, Harry is startled by an eerie, malevolent voice. He first encounters it while serving detention in Gilderoy Lockhart's office and later in the presence of Ron and Hermione. Although Lockhart, Ron, and Hermione are unable to perceive it, Harry, upon hearing the voice again, bolts down the corridor in pursuit. Before long, the Trio stumbles upon a blood-curdling message scrawled on the wall ahead:
The Chamber of Secrets has been unlocked. Beware, enemies of the heir...
They also witness the cursed and lifeless body of Argus Filch's cat, Mrs. Norris. In the ensuing moments, Dumbledore reveals that Mrs. Norris has been petrified and advises everyone to exercise caution.
Tom Riddle Framed Hagrid
Professor Minerva McGonagall in Harry Potter and the Chamber of Secrets explains that Salazar Slytherin, one of the four founders of Hogwarts, disagreed with the school's views on magical learning and decided to leave. However, before his departure, Slytherin constructed a hidden chamber called the Chamber of Secrets in Hogwarts Castle. This chamber was home to a Basilisk, and Slytherin sealed it so that only his true heir could open it. The heir would have the power to control and unleash the Basilisk. While Minerva considers the chamber and the beast to be mere legends, the truth is that Slytherin's heir, Tom Riddle, opened the Chamber 50 years ago.
Under Riddle's control, the Basilisk attacked numerous students and killed Myrtle Warren. Riddle cunningly framed Rubeus Hagrid, a third-year student at the time, for the attacks and blamed Hagrid's pet Acromantula, Aragog. This tactic led to Hagrid's expulsion from Hogwarts and the destruction of his wand. However, Headmaster Albus Dumbledore, the Transfiguration teacher at the time, believed in Hagrid's innocence and convinced Headmaster Armando Dippet to allow Hagrid to stay at Hogwarts and train as the gamekeeper. While the rest of the school accused Hagrid, Dumbledore saw through Riddle's deception.
Hagrid Is Released From Azkaban
Despite lacking any evidence that implicated Hagrid in the opening of the Chamber of Secrets, Minister for Magic Cornelius Fudge had him imprisoned in Azkaban, citing his record as grounds for arrest. However, Fudge promised to release Hagrid if another suspect was apprehended. In "The Chamber of Secrets," Harry took it upon himself to venture into the chamber, defeat the Basilisk, and destroy Tom Riddle's enchanted diary. Prior to this, the ghostly memory of Tom Riddle, trapped within the diary, confessed to framing Hagrid and manipulating Ginny to open the Chamber. By the end of the second Harry Potter film, Dumbledore returned as Hogwarts' Headmaster and entrusted Ron with delivering Hagrid's release papers to Azkaban via owl. Though Hagrid arrived at the end-of-year feast a bit late, his return was met with great joy from everyone in attendance. Harry's heartfelt words, "There's no Hogwarts without you, Hagrid," exemplify the gamekeeper's importance to the school. Not only did Hagrid diligently carry out his responsibilities, but he had also formed meaningful connections with the students. The entire High Table erupted in cheers and applause for him, and Hagrid made sure to express his gratitude to the Trio at the Gryffindor table.
