• That evening, Luo Bin returns Snape’s office key and asks for a small piece of African Tree Snake skin. He indirectly hints that he witnessed something important during the match. Snape gives him the ingredient, then listens as Luo Bin reveals that Dobby, a house-elf, has been acting to endanger Hogwarts students.
• Snape warns Luo Bin to keep the matter secret, since publicizing a house-elf’s attempted attack could worsen house-elves’ treatment. Luo Bin leaves, understanding that Snape intends to take the matter to Dumbledore.

• Humor and practical help offer some relief amid the growing danger, though careless actions can make things worse.

• During Lockhart’s demonstration, Draco’s conjured Black Snake becomes dangerously aggressive toward Justin Finch-Fletchley. Harry speaks to it in Parseltongue, but the onlookers mistake his words for commands to attack.
• Luo Bin casts Petrificus Totalus, freezing the snake before it can bite Justin. Justin collapses in fright, and his fellow Hufflepuffs shield him from Harry.
• The crowd recoils from Harry when they learn he is a Parselmouth. Snape watches him with a calculating expression, while Lockhart is shocked.
• In the common room, Harry tells Ron, Hermione, and Luo Bin that he once spoke to a python at a reptile house. He insists he was telling the Black Snake to stop, not to attack.
• The friends explain that, because they could not understand Parseltongue, Harry’s hissing and the snake’s behavior looked threatening. They doubt Justin—or the wider school—will believe his explanation.

Character developments and interactions

• Harry is confused by the stigma attached to his ability and does not initially realize that speaking with snakes is unusual. He is sure he acted to protect Justin, but begins to understand how frightening he appeared.
• Luo Bin intervenes decisively to save Justin, then gives Harry a blunt explanation of how his actions looked to others.
• Ron and Hermione question Harry and help him understand why people may suspect him. Ron is briefly injured when Harry springs up and accidentally hits his chin.
• Justin is terrified and assumes Harry may be a threat; Hufflepuff students protect him from Harry.
• Snape remains watchful and intrigued, while Lockhart proves ineffective during the danger.

Significant themes

• Appearance versus intent: Harry tries to prevent harm, but others interpret his words and actions as menace.
• Fear and prejudice: Harry’s Parseltongue ability links him in others’ minds to Salazar Slytherin and the possibility that he is the Heir.
• The limits of communication: Because nobody else understands Parseltongue, Harry cannot make his intentions clear when it matters most.

Plot points and events

• After the snake incident, Harry insists that his Muggle-born mother means he cannot be Salazar Slytherin’s heir. Luo Bin reminds him that ancestry is difficult to establish and encourages him to speak to Justin once he has calmed down.
• News of the incident spreads through Hogwarts. Students avoid Harry, leaving him miserable as Ron takes him back to the dormitory.
• Draco is shaken by the snake’s disappearance but refuses to admit fear or apologize to Justin. Luo Bin suggests making amends with gifts instead.
• The next morning, Draco visits the Hufflepuff dormitory with expensive toys and returns with five apples, which he says are a thank-you gift for Justin. He claims Hufflepuffs are blaming Harry rather than investigating who conjured the snake.
• With Herbology canceled because of heavy snow, Luo Bin goes to the library. He finds Harry secretly listening to a group of Hufflepuffs discussing the attack.
• Ernie Macmillan and others argue that Harry is the Heir of Slytherin, citing his Parseltongue, unusual survival as a baby, and supposed conflicts with Filch and Colin. Hannah Abbott doubts the accusation, but Susan Bones urges her to believe Harry is dangerous and claims Justin may be his next target.
• Luo Bin steps out, interrupting the discussion. Ernie thanks him for saving Justin with the Full Body-Bind Curse; Luo Bin downplays the spell’s difficulty.

Character development and interactions

• Harry feels isolated and distressed as suspicion spreads. He listens in on the Hufflepuffs’ conversation, apparently trying to learn what people believe about him.
• Luo Bin acts as a calm, practical mediator: he comforts Harry, advises Draco, and defuses the Hufflepuffs’ discussion by reminding them that the curse was not exceptional.
• Draco shows guilt and fear beneath his pride. Though he refuses to apologize, he makes a conciliatory gesture by bringing gifts for Justin.
• Hannah remains reluctant to condemn Harry, recalling his kindness and past heroism. Ernie and Susan, by contrast, interpret rumors and past events as evidence against him.
• Justin, though absent from the library scene, remains central to the Hufflepuffs’ concern; their fear for his safety fuels their suspicion of Harry.

Significant themes

• Fear and rumor: Students turn incomplete or distorted events into a convincing case against Harry.
• Prejudice and scapegoating: Harry is judged by his ability to speak to snakes and by his unusual past, while Justin’s Muggle background makes him seem especially vulnerable.
• Guilt and making amends: Draco struggles to acknowledge responsibility, but his gift suggests a first step toward repairing harm.
• Courage and bystander behavior: The students’ panic during the attack contrasts with Luo Bin’s decisive action to protect Justin.

Plot points and events

• Hufflepuff students Hannah, Susan, and Ernie suspect Harry is the Heir of Slytherin because he speaks Parseltongue and was near the snake that attacked Justin. Luo Bin defends Harry, insisting he would never harm students.
• Harry arrives and explains that he was telling the snake to stop, but the students refuse to believe him. Luo Bin pulls him away before the argument escalates.
• Hurt by the sudden hostility, Harry says that people once praised him as a hero but now blame him. He asks Luo Bin to leave him alone and storms off.
• Later, Justin Finch-Fletchley is found petrified in a corridor, with Nearly Headless Nick transformed into a terrifying black, vaporous ghost. Harry is standing beside Justin, stunned.
• Peeves claims he saw Harry attacking Justin and stokes panic. Ernie again accuses Harry of being the Heir, and the crowd chants for Harry to be expelled. Professor McGonagall restores order, while professors carry Justin to the Hospital Wing. Nick cannot be moved because he is a ghost.

Character developments and interactions

• Harry becomes increasingly isolated and distressed as people reject his explanations. The crowd’s accusations make him feel that Hogwarts can be as hostile as the Dursleys’ home.
• Luo Bin remains Harry’s defender, challenging Ernie and Peeves and trying to get Harry to explain himself.
• Ernie grows more openly suspicious and confrontational, interpreting the attacks as evidence against Harry.
• Peeves exploits the crisis for amusement, inventing a lurid story that casts Harry as a vampire.
• McGonagall intervenes firmly to stop the panic and manage the emergency.

Significant themes

• Fear and scapegoating: The students turn suspicion into certainty, treating Harry as guilty without proof.
• Reputation and fickle public opinion: Harry’s past heroism offers little protection once fear takes hold.
• Miscommunication and prejudice: Harry’s Parseltongue explanation cannot reassure people who already distrust him.
• Isolation: Harry is surrounded by accusations yet unable to make himself heard.

Plot points

• After Nearly Headless Nick is sent to the Hospital Wing with Ernie fanning him along, Professor McGonagall escorts Luo Bin and Harry to Dumbledore’s office by a hidden route, avoiding the attention Harry would attract in the corridors.
• In the office, Harry angrily kneads the Sorting Hat, which again tells him he belongs in Slytherin. Harry insists he is not Slytherin’s heir and had nothing to do with the attacks or the Chamber of Secrets.
• Luo Bin recognizes that the Hat is teasing Harry, tells it to stop, and then puts it on himself—only to pull it off before it can read his thoughts. He tosses it back onto its shelf.
• The former headmasters’ portraits wake and bicker. Their conversation hints that Everard’s portrait may let him observe the Ministry of Magic for Dumbledore.
• Luo Bin draws attention to Fawkes, who looks nearly featherless and frail. Harry fears he may have harmed the bird; Luo Bin explains that Fawkes is a phoenix, a creature reborn in flames.

Character developments and interactions

• Harry is exhausted and distressed, and his frustration with the Sorting Hat reflects how deeply the accusations surrounding the attacks are affecting him. He also worries that Fawkes’s condition is his fault.
• Luo Bin acts as a calm mediator: he explains the Hat’s teasing, defends Harry, and reassures him about Fawkes. He also shows familiarity with Hogwarts’ unusual magic and history.
• McGonagall is brisk and protective, guiding the boys discreetly while making clear that Harry’s situation is beyond her authority.
• The portraits are lively and argumentative, offering both comic relief and a glimpse of possible information-gathering at the Ministry.
• The Sorting Hat is mischievous but ultimately agrees to stop provoking Harry after Luo Bin calls it out.

Significant themes

• Being misunderstood and judged: Harry’s distress stems from others connecting him to Slytherin and the attacks despite his denials.
• Compassion and emotional support: Luo Bin recognizes Harry’s vulnerability and intervenes rather than dismissing his anger.
• Secrecy and observation: The concealed route to Dumbledore’s office and the hint about Everard’s portrait suggest that information and privacy are important at Hogwarts.
• Death and renewal: Fawkes’s apparent decline introduces the idea of phoenix rebirth, transforming what looks like imminent death into the promise of renewal.
