Hermione agrees, but Luo Bin cautions that they have no evidence and the professors are unlikely to believe them. He remains convinced that Quirrell is the real threat.
• Harry and Hermione prepare to leave the Astronomy Tower, nearly forgetting the Invisibility Cloak. Luo Bin retrieves it in time to hide them from Filch.

• Promises and secrecy: Luo Bin refuses to disclose what he promised to keep private, even when Hermione asks.

• Key events: After Norbert is safely sent away, Luo Bin tells Draco that Crabbe has caused serious trouble. Crabbe’s false Fire Dragon story lured Neville into the halls at night, costing Gryffindor and Slytherin fifty House Points each. Though students gossip about both boys, Harry, Ron, Hermione, and Luo Bin privately support Neville and help him during his punishment. Crabbe is scolded by Draco and made to clean the broom shed for a month with a gleaming bald head; Goyle’s idea of keeping him company by eating cake only makes him angrier.
• Exams begin: Once the punishments end, students turn their attention to studying. Hermione drills Harry, Ron, and Neville on exam topics, while Luo Bin balances revision with Snape’s assignments, Quidditch practice, caring for Xiao Ying, avoiding Draco, and nightly meditation to build his magical reserves. Hermione and Luo Bin compare written-exam answers after each paper, frustrating Ron, who gets struck with a book after complaining about her.
• Practical exams: Hermione and Luo Bin review before the practical exams, while Harry and Ron choose to study or rest. In Flitwick’s exam, students must make a pineapple dance across a desk. Harry performs well, Ron’s pineapple repeatedly falls, and Neville’s grows limbs, tumbles off the desk, and becomes pineapple pie; he is gently told he cannot retake the exam. In McGonagall’s Transfiguration exam, students must turn mice into Snuffboxes. The chapter ends as Luo Bin studies the mouse and wonders how to make the transformation.

Crabbe faces consequences, while Goyle’s teasing companionship deepens his irritation. Hermione’s diligence and confidence dominate the group’s studying, and she and Luo Bin work smoothly together; Ron resents her bossiness, while Harry tries to prevent their arguments. The exam results also highlight contrasting abilities: Harry’s natural knack for practical magic, Ron’s uneven performance, and Neville’s continuing struggles.
  Themes: The chapter emphasizes loyalty and kindness toward someone who has been unfairly blamed, accountability for mischief, and the pressure of exams. It also contrasts different approaches to learning—Hermione’s intensive preparation, Harry and Ron’s choices to study differently, and Luo Bin’s disciplined effort to balance academics with broader magical development.

Plot points and events

• Luo Bin overcomes his difficulty in the Transfiguration practical by noticing that a mouse’s bright eyes resemble the jewels on a Snuffbox. He transforms the mouse into an ornate, crackle-glazed porcelain box, impressing Professor McGonagall.
• Afterward, Hermione asks him to transform a toy mouse as well. Ron, embarrassed because his own Snuffbox still has a mouse tail, dismisses Luo Bin’s work, but Harry and Hermione explain that valuable porcelain can be worth more than gold.
• The group heads to the Potions practical, where students must brew a Forgetfulness Potion using easily confused ingredients. Luo Bin, experienced from studying with Snape, finishes the assigned potion first.
• Snape criticizes the textbook-perfect result as lacking originality and gives Luo Bin an extra task: invent a potion from the remaining ingredients. Professor Sprout objects that Luo Bin is only a first-year, but Luo Bin chooses to accept the challenge.
• While Snape unsettles Harry and Neville during his rounds, Sprout gives Luo Bin clues about two unfamiliar ingredients: Bubotuber juice can reduce toxicity and side effects, while Fanged Geranium can relieve pain when fresh.
• Luo Bin uses the ingredients to create a faint-pink Swelling Potion. Its preparation produces a loud burst that startles the room. Snape clears the other students’ attention away, then tests Luo Bin’s claim by placing a mouse on the desk and warning that failure will cost him his practical grade.

Character developments

• Luo Bin shows ingenuity in both exams: he finds an unexpected visual connection for Transfiguration and applies ingredient clues creatively in Potions. He is also willing to take on a difficult extra challenge.
• Hermione remains curious and enthusiastic, asking Luo Bin to demonstrate his Transfiguration again and sharing practical knowledge about valuable porcelain.
• Ron is still stung by his imperfect transformation and responds with jealousy and defensiveness.
• Snape remains severe and provocative, pressuring students while demanding more than rote textbook work. His final test puts Luo Bin’s invented potion—and exam score—on the line.

• Observation and connection: Luo Bin succeeds by noticing shared traits and interpreting ingredient properties.

• Plot and events: During his Potions practical, Luo Bin tests a Swelling Potion on a mouse. After a grotesque but apparently painless spell of contortions, the mouse grows to basketball size. Snape contains it and judges Luo Bin’s work a bare pass. Luo Bin then gives Harry, Ron, and Hermione one bottle each, explaining that the potion’s swelling lasts thirty minutes—possibly less because of his added ingredients. The friends joke about using it on Vernon or Scabbers, while Hermione warns against using magic on Muggles.
  The next day, Luo Bin finishes the History of Magic exam early. Professor Binns praises his concise answers but criticizes his handwriting. After the exam, Hermione vents her frustration about the questions by throwing dirt into the lake, drawing George’s protest. Luo Bin becomes distracted by the Giant Squid and imagines cooking it. Harry then tells the group that he has repeatedly dreamed of a red-haired woman warning him he is in danger, and that his scar’s pain wakes him. He fears Voldemort is nearing the Philosopher’s Stone. Luo Bin tries to reassure him, and Hermione points to Dumbledore’s protection, but Harry remains anxious.
• Character developments: Luo Bin demonstrates practical ingenuity by successfully producing a potion despite his uncertainty, but receives only a marginal pass. He is also shown as homesick for familiar food and increasingly preoccupied with cooking. Harry’s recurring dreams and painful scar deepen his sense of impending danger. Hermione remains studious and cautious, while Ron responds with humor and impatience.
• Character interactions: Hermione cautions Harry and Luo Bin about the risks of giving potions to Muggles; Ron mocks her lecture, then jokes about dosing Scabbers. Binns gives Luo Bin unexpected feedback on his handwriting. George calls across the lake when Hermione’s thrown clod disturbs the squid. Finally, Harry shares his fears with his friends, who try to calm him, though their reassurances do not dispel his foreboding.
• Significant themes: The chapter mixes comic school-life details with growing suspense. Its playful potion experiment, exam frustrations, and food fantasies contrast with Harry’s ominous dreams and fear that Voldemort is approaching the Stone. Hermione’s warning also highlights the boundaries and consequences of using magic.

• Luo Bin opens his Black Obsidian bracelet and releases Xiao Ying, a Flower Fairy. She agrees to help in exchange for twenty boxes of honey.
