First Appearance	Chapter 6

Background

Hermione was raised by Muggle parents, both dentists. Professor McGonagall’s visit and demonstration of Transfiguration overturned her understanding of the world, but also made her acutely aware that wizard-born children had years of magical exposure she lacked. She spent the summer before Hogwarts relentlessly reading and attempting self-taught spellwork to overcome that perceived disadvantage. 12

She first met Vaughan Weasley while shopping in Diagon Alley with her parents, and was impressed by his casual magic. Learning that he was younger than her intensified her determination to improve. 6 12

On the Hogwarts Express, Hermione unsuccessfully sought magical discussion partners among fellow first-years. Her bluntness and intense approach alienated Susan Bones and Ron Weasley, while a nervous encounter with Vaughan was interrupted by Draco Malfoy’s insult toward her Muggle-born status. 12

She was sorted into Gryffindor alongside Harry Potter and Ron Weasley. 14

Appearance

Hermione is described as a brown-eyed girl with initially bushy, fluffy brown hair. As she grows older, she becomes taller and begins paying more attention to her appearance. 78 132 146

• Her hair was later straightened and braided for her visit to the Weasley family. 132
• Her slightly oversized front teeth were reduced to their proper size with her father’s help and a potion. 146
• Vaughan develops a shampoo specifically for her hair, which she uses. 145
• Her hair becomes untidy again during periods of particularly intensive research and study. 348
• During the Potions exchange selection assessment, her deliberately flawed potion causes her hair to grow uncontrollably. She stops the growth with an antidote and cuts away the excess. 401 402

Personality

Hermione is intensely curious, disciplined, and competitive. Her fear of falling behind as a Muggle-born student drives her to study beyond the curriculum, complete work far in advance, and continually pursue unfamiliar fields of magic. 12 127 296

Her direct, pedantic manner initially leaves her isolated from other girls and causes friction with Harry and Ron. She eventually recognizes that her blunt advice and intimidating intensity have hurt her relationships, though she remains unwilling to compromise her standards merely for popularity. 23 24 85

Despite her sharp tongue, Hermione is compassionate and principled. She tries to rescue an injured fairy despite knowing it is temperamental, argues for werewolves’ rights, and consistently acts to protect her friends. 100 281

She matures into a more observant and pragmatic thinker through her relationship with Vaughan. She learns when to pursue an answer and when to respect another person’s secrets, while retaining her own moral concerns. 100 124 146

Her devotion to research can become excessive: while studying Vaughan’s magical-protein work, she becomes so engrossed that she neglects her own well-being. Her ambition is not merely to remain his girlfriend, but to understand his difficulties and become a genuine fellow traveler in his work. 296 348 354

Hermione’s idealism becomes increasingly evidence-based. Her campaign for house-elf freedom initially assumes that freedom is necessarily what the elves themselves should want. After Vaughan presents his observations and a hypothesis of inherited domestication, she acknowledges that she has oversimplified the issue and suspends the campaign rather than imposing her beliefs on the elves. His encouragement helps her redirect her resolve toward a longer-term research goal. 371 372

She also develops a stronger sense of public responsibility. She rejects attempts to evade Harry’s international reputation through deliberate weakness, warns against retaliating impulsively against a visiting witch, and refuses to use her relationship with Vaughan to bypass the Potions exchange’s selection process. 376 378 405

Her loyalty can nevertheless place her in morally uncomfortable situations. When asked to monitor Harry and Ron, she struggles between friendship and trust in Vaughan, ultimately concealing what she knows and using magical assistance to lie convincingly. 394 402

Her desire for independence also extends to money: she refuses a share of Ron’s earnings from selling Potions exam predictions, insisting that she can earn her own. 403

When the Daily Prophet turns against Vaughan, Hermione distinguishes reported facts from hostile commentary rather than accepting the newspaper’s interpretation. She suspects concealed circumstances without denying that he has genuinely angered many people, and encourages Ginny to trust that he has reasons for his actions. 475

Hermione remains hurt by Harry and Ron’s secrecy, but does not let resentment prevent her from helping during another threat involving Voldemort’s Diary. She recognizes that the trio needs stronger allies and later takes control when an argument leaves the boys unable to plan calmly. Her intervention also requires her to act as though she lacks the privileged knowledge she holds about Vaughan’s arrangements. 480 481 490

Abilities & Skills

Academic Aptitude

Hermione rapidly closes the gap she perceives between herself and wizard-born students through independent study.

• Earns house points with Vaughan in Transfiguration and Herbology through strong textbook knowledge. 19 21
• Studies second-year material before completing her first year. 127
• Has completed the second-year curriculum and begins studying third-year subjects and advanced Potions independently. 296
• Reads Vaughan’s research even when its Muggle-science concepts exceed her current knowledge, intending to understand it later. 262
• Finishes the sixth-year Potions textbooks and proceeds to advanced Potions while still a second-year student. 345
• Independently studies Muggle molecular biology to follow Vaughan’s interdisciplinary research. 348
• Is the only second-year to earn top marks across the board in the professors’ assessments before the international delegations arrive. 376
• Learns Vaughan’s science-based spells more readily than visiting students because of her existing Muggle knowledge and continued independent study. 419
• Her continuing excellence is particularly noted in Potions and Charms. Harry explicitly recognizes that neither he nor Ron is at her level. 480

Spellcasting

Hermione is a capable practical caster whose magic is especially effective when she remains composed.

• Uses the Disillusionment Charm to conceal herself, Harry, and Ron during their attempt to reach the Philosopher’s Stone. 111
• Casts the Shield Charm quickly enough to block Quirrell’s first Disarming Charm, though the shield is overpowered. 116
• Combines defensive casting, evasive movement, and the Disarming Charm in combat against Quirrell. 118
• Uses the Impediment Jinx to slow giant wolves during the Defence Against the Dark Arts survival trial. 250
• Produces a broad, forceful stream of fire with the Fire-Making Spell to illuminate a dangerous forest path. 251
• Easily masters the Levitation Charm compared with Harry and Ron. 274
• Uses a Cleaning Charm after the practical class, impressing other students. 253
• Casts Vaughan’s Multispectral Vision Charm in infrared mode to locate people in darkness during a pursuit through the Forbidden Forest. 386
• Enchants the trio’s ears so they can overhear a distant conversation. 387
• Uses the Multispectral Vision Charm to perceive infrared waves associated with incoming magic and judge the timing of an attack. 388
• Maintains a Super-Sensory Charm during the confrontation with Hastings, sharpening her senses as she tracks the approaching spell. 388
• Times a Perfect Shield Charm to reflect Jason Hastings’s Exploding Charm back at him. The counterattack injures him, though it does not immediately end the pursuit. 388
• Casts Lumocecuren, Vaughan’s science-based spell derived from the Lumos framework. Its invisible light pulse blinds Hastings and leaves him disarmed and helpless before he can complete his next attack. 388
• Uses the unfinished Essence Charm without difficulty because she understands its principles, applying it while rapidly preparing an antidote. 401
• Restores Harry and Ron after their assessment potions transform them into girls. 402
• Has learned numerous jinxes from Vaughan, contributing to the practical advantage Harry recognizes she holds over him and Ron. 480

Deduction and Planning

Hermione applies research, conversation, and careful observation to solve problems.

• Identifies Quirrell as the professor whose movements matched the Gringotts robbery. 101
• Deduces that Quirrell intends to act during lunch by using a plausible historical question to arrange separate follow-up conversations with him and Professor Flitwick. 112
• Organizes Harry and Ron’s search for Dumbledore, assigning each person according to their strengths. 111
• Recognizes Harry’s sentient diary as a likely Dark Magic object and challenges his assumption that it could be an ancient benign artifact. 260
• Realizes during the Philosopher’s Stone crisis that Vaughan and Dumbledore may be deliberately luring Quirrell into action, but chooses not to share her suspicions with Harry. 112 114
• Develops an understanding of media bias after handling Vaughan’s correspondence and discovering Rita Skeeter’s connection to him. She recognizes that apparently independent reporting may reflect political loyalties or patrons. 302
• Explains why pretending to be a Squib or deliberately performing poorly would worsen Harry’s predicament before the visiting schools, urging honest assessment and training instead. 376
• Directs the trio’s pursuit of Lucius Malfoy and his companions, recruiting Fruit Tea as a guide and combining concealment, secret passages, infrared vision, and enhanced hearing. 386 387
• Recognizes that Hogwarts’ Anti-Apparition protection prevents an immediate escape when the trio is discovered in the Forbidden Forest. 387
• Recognizes that Ron’s exam predictions draw on potions discussed in Vaughan’s published papers. 403
• Responds critically to the Daily Prophet’s hostile coverage of Vaughan, separating factual information from opinion and planning to seek his explanation directly. 475
• Recruits Fruit Tea and helps bring Fred and George into the renewed Diary investigation, recognizing that three young students are insufficient against Death Eaters. 480 481
• Knows how to immobilize the Whomping Willow and open the hidden passage beneath it, which she uses to reach the twins’ secret base with Ron. 480
• Proposes searching for both Colin Creevey and Peeves, reasoning that locating those believed to know the Diary’s whereabouts could prevent Snape and Voldemort from obtaining it. 481
• Notices Hagrid’s apparent reservation about the accusation against Snape and redirects the conversation instead of confronting him. 481
• Takes over planning when Harry and Ron’s argument prevents them from remaining calm, reasoning from Harry’s perspective while concealing her own knowledge of Vaughan’s plan. 490

Research Assistance

Hermione becomes Vaughan’s research assistant after demonstrating that she can follow his attempts to merge magical theory with Muggle science. 348

• Understands that his proposed universal functional group will use Fluxweed’s transformation properties after only a small hint. 345
• Learns the principles behind using Felix Felicis, Fluxweed, and Acromantula-derived material in the proposed creation of magical proteins. 348
• Assists Vaughan’s work by bringing meals, studying advanced Potions, and recording material she cannot yet fully understand. 345 348
• Her ability to connect scientific and magical concepts makes her Vaughan’s first identified “fellow traveler” in his pursuit of magical truth. 348
• Handles correspondence and medicinal ingredients before taking on a more substantial research role. Vaughan initially instructs her to observe and think more, while doing less practical work. 302 345
• Helps Harry investigate the magical-protein proposal when public criticism prompts him to seek an independent understanding of the research. 354
• Records Remus Lupin’s trial of Wolfsbane Potion version 2.1 in the preserved portion of Vaughan’s suitcase world containing a “Magical Moon.” The trial prevents Lupin’s transformation, though it remains painful and requires further refinement. 398
• Continues assisting in Vaughan’s laboratory after losing her opportunity to participate in the formal Potions exchange. 405
• Spends a night reading with Vaughan in the laboratory, subsequently concealing the visit from Harry and Ron. 407
• Accompanies Vaughan to a late-night supper with Dumbledore and Li Nanyu, identifying herself as his research assistant and witnessing his explanation of the broader social risks of his inventions. 422

Independent Research Goals

Vaughan encourages Hermione to pursue work of her own while remaining his assistant, hoping that her future discoveries will earn recognition under her own name. He sees particular promise in her capacity to synthesize information, solve problems, and develop methods that could make difficult research accessible to more ordinary wizards. 371 372

Her proposed long-term research direction concerns reversing the effects of artificial selection on house-elves. This develops from Vaughan’s hypothesis that centuries of selective breeding have shaped their physiology and inherited behavior, making a simple emancipation campaign or temporary potion inadequate to address the underlying issue. This remains a research goal rather than an achieved treatment. 371

Magical Equipment

• Enchanted shoulder bag — A gift from Vaughan, concealed inside an Easter egg, which she uses to carry her notebook and later potion ingredients. 100 401
• Wish-Granting Paintbrush — A limited-use reward obtained in Fairy Tale Town that draws desired items within worlds inside paintings when used with devout faith. The trio uses it to create broomsticks during the Philosopher’s Stone trials. 117
• “The Deceiver” Personality Armament — Helps Hermione lie without revealing her deception while she conceals her knowledge of Vaughan and Dumbledore’s plans from Harry and Ron. 402

Relationships

• Vaughn Weasley — Initially an intimidating magical prodigy and rival in Hermione’s eyes; he later becomes her tutor, confidant, boyfriend, and research partner. Their relationship is publicly acknowledged during the Grangers’ visit to The Burrow. He encourages her to develop independent research ambitions, entrusts her with monitoring Harry and Ron during the exchange, and shares the secret of his Thousand Transformations Charm with her. She later witnesses him disclose the spell and his regulatory ambitions to Dumbledore and Li Nanyu, supports him during hostile newspaper coverage, and continues cooperating with his plans while helping her friends. 12 43 100 133 348 372 394 421 422 475 490
• Harry Potter — Close friend and frequent investigative partner. Hermione provides planning, research, and practical support during the Philosopher’s Stone crisis and the diary investigation. She later helps him confront the gap between his public reputation and actual skills, protects him during the encounter with Hastings, and conceals her involvement in Vaughan’s monitoring of his actions. His continued secrecy damages her trust, but she joins the renewed search for the Diary after learning that he has deliberately lowered his Occlumency defenses to investigate Voldemort. She initially intends to let him lead, as Vaughan wishes, before circumstances force her to take over planning. 111 112 260 376 388 402 475 480 481 490
• Ron Weasley — Close friend with a frequently argumentative dynamic. Ron resents Hermione’s attachment to Vaughan at times, but they continue to work together and reconcile after disagreements. His jealousy causes another rupture during the Potions exchange, though his later wish for her help and their shared laughter show that the friendship remains important to both of them. He eventually seeks her help with Harry’s dangerous investigation and accompanies her through the Whomping Willow passage. During the expanded search, he assigns her to work with the twins because he considers her best able to keep them under control. 21 260 266 392 395 402 480 481
• Ginny Weasley — Develops a warm friendship after Hermione joins the Weasley family during summer; Ginny welcomes her as someone with whom she can discuss matters her brothers cannot understand. Hermione later gently teases Ginny about watching Harry and listens as she distinguishes her childhood admiration for the legendary hero from her feelings toward the ordinary boy. During the Daily Prophet’s campaign against Vaughan, Hermione reassures the upset Ginny that he likely has reasons for his actions and deserves their trust. 133 373 475
• Nymphadora Tonks — Hermione is fascinated by Tonks’s Metamorphmagus ability and later befriends her through shared curiosity and eagerness to learn. 136 137
• Rubeus Hagrid — A friend and guide during her early trips into the Forbidden Forest; he introduces her to magical creatures and supports her relationship with Vaughan. He joins the renewed Diary investigation, during which Hermione notices his apparent reservations about the group’s suspicions of Snape. 25 100 481
• Isabella Rosier — Hermione initially feels jealous and threatened by Rosier’s closeness with Vaughan, but later engages actively with Rosier’s Defence Against the Dark Arts practical lessons. Rosier praises Hermione’s composure and adaptability. By a later meeting during the exchange, Hermione’s concern about Rosier relates to Karkaroff’s targeting of her rather than jealousy over Vaughan. 237 249 250 253 435
• Cho Chang — Develops a friendly connection with Hermione during the international exchange. Hermione learns about Chinese culture from her, helping inspire Vaughan’s suggestion that Hermione serve as Hogwarts’ liaison to the Central Refining Academy. Cho also supports and comforts Hermione after Fleur’s provocative request to approach Vaughan upsets her. 392 394 397
• Hokey — Her delighted response to Hermione’s request for a meal helps Hermione reconsider her discomfort with accepting house-elf service. Vaughan encourages Hermione to treat the elves as friends while seeking a workable solution to their broader circumstances. 372
• Cheng Quandao — Hermione initially finds him unsettling and later feels mildly jealous of his access to Vaughan as a new assistant. Vaughan’s reassurance improves her mood, while her advice about the Spectral Vision Charm proves relevant to the hazards of his laboratory work. 394 398 402
• Remus Lupin — Hermione participates in documenting his Wolfsbane Potion version 2.1 trial, connecting her support for werewolves with practical research assistance. 398
• Dolores Umbridge — Hermione strongly dislikes Umbridge’s patronizing treatment of her as Vaughan’s fortunate girlfriend. She is angered by Umbridge’s attempt to exploit Harry and Ron’s misconduct for political leverage. 394 402
• Fruit Tea — A recurring companion and capable investigative ally. Vaughan deliberately leaves the magically resistant cat near Hermione for protection, and Hermione can ask her to lead the way to him. She later recruits Fruit Tea’s guidance and animal network for investigations; the cat readily assists with the renewed Diary search. Fruit Tea’s jealousy toward Hermione varies with Vaughan’s presence. 290 386 480 481
• Fred and George Weasley — Their teasing repeatedly embarrasses or irritates Hermione, including jokes about Rosier and the later nickname “the boss’s lady.” Nevertheless, she helps recruit them for the renewed Diary investigation and is assigned to search for Peeves with them. 133 234 480 481
• Fleur Delacour — Fleur’s attempt to have Hermione relay a request for access to Vaughan provokes Hermione’s anger during the international exchange. The encounter reinforces Hermione’s protectiveness toward her relationship, while Cho supports her. 397

Story Role / Major Arcs

First Year

Hermione arrives at Hogwarts determined to compensate for her Muggle-born background through study. Her early isolation and conflict with Harry and Ron gradually give way to friendship, while Vaughan’s support and attention become increasingly important to her. 12 24 43

During the Philosopher’s Stone crisis, Hermione becomes a central planner for Harry and Ron. She deduces Quirrell’s likely timing, coordinates their search for Dumbledore, enters the trial space with them, and fights Quirrell directly. 101 111 112 116 118

She also begins to perceive the adults’ concealed planning. Recognizing that Vaughan and Dumbledore may have intentionally created an opportunity for Quirrell, she withholds her suspicions from Harry. The trials force her to confront the possible costs of Harry’s growth and the cruelty of his connection to Voldemort. 112 114 117

Afterward, she stays with Vaughan in the headmaster’s office and helps him recover from his Snake Kiss injuries. The portraits welcome her warmly, calling her “the studious Granger.” 121 123

She subsequently helps Harry and Ron revise after their poor quiz results encourage them to take their studies more seriously. The screening of Harry Potter and the World Within the Painting also makes the trio more widely known among Hogwarts students. 126 129

Relationship with Vaughan

Hermione’s bond with Vaughan develops from awkward gratitude into romance. She seeks his help with Transfiguration, supports him through political pressure, accepts his invitation for her family to visit the Weasleys, and receives a Valentine’s gift intended to help her form friendships with other girls. 43 77 78 85

She officially becomes Vaughan’s girlfriend during the summer after first year and is welcomed into the Weasley household, particularly by Ginny. 132 133

During the summer, she observes the proceedings exposing Gilderoy Lockhart’s fraud and supports Vaughan when he stays at the Grangers’ London home to handle business matters. Their private conversations frequently concern magic, philosophy, and Muggle science rather than romance alone. 134 135 146

Their relationship increasingly combines affection with intellectual partnership. Vaughan encourages her to remain his assistant without surrendering ambitions of her own, and Hermione accepts more responsibility in his research and the exchange’s affairs. Despite this access, she refuses to exploit their relationship to regain a place in the formal Potions exchange after failing its selection assessment. 372 394 405

When Vaughan demonstrates his Thousand Transformations Charm, Hermione quickly grasps the dangers posed by a spell capable of producing numerous disguises. She warns that widespread knowledge could destabilize wizarding society, and he assures her that he has no immediate plans to release it. Her concern then shifts toward the unfairness of keeping such a major achievement unrecognized. 421

The two then join Dumbledore and Li Nanyu for a late-night hot pot in the headmaster’s office. Hermione presents herself as Vaughan’s research assistant, participates in the rule-breaking visit, and is surprised when he shows the transformation spell to the older wizards. She witnesses his argument that magical proteins and new transformation techniques may require new rules, including contractual or oath magic to regulate their use. 422

Second Year and the Diary Crisis

Hermione returns to Hogwarts focused on broadening her knowledge, but her friendships with Harry and Ron become strained when Harry conceals his sentient diary and distrusts Vaughan’s warnings. She ultimately helps them assess the diary as Dark Magic and investigate its danger. 236 260

She also learns from Vaughan that the diary is a Horcrux and receives confidential information about Voldemort’s prophecy and the Savior Protection Plan. 290

Defence Against the Dark Arts Practical Classes

Hermione questions the risks of Professor Rosier’s wilderness-survival practical class before participating. During the trial, she remains calm under pressure, identifies danger quickly, protects Ron with the Impediment Jinx, and helps Harry’s team become the only group to clear the first stage. 249 250 253

During a later practical lesson, she works with Harry and Ron to investigate an angry Occamy, suspecting that a student has stolen its baby. 280

Magical-Protein Research

Hermione pushes herself through advanced Potions, Alchemy, and Muggle scientific material to understand Vaughan’s work. Her ability to follow his logic earns her a formal place as his research assistant in the development of magical proteins and the universal functional group. 296 345 348

The controversy surrounding magical proteins draws Harry into her studies as he seeks to understand the proposal independently rather than simply accepting newspaper criticism. Hermione’s own immersion in the work becomes intense enough to affect her well-being. 354

She later records the trial of Wolfsbane Potion version 2.1 with Lupin and Cheng present. The potion prevents Lupin from transforming under the “Magical Moon,” but its painful symptoms and incomplete protection show that further research is necessary. Hermione remains involved in laboratory work throughout the exchange even without a place among its selected student participants. 398 405

Her close access to Vaughan’s work includes an all-night reading session in the laboratory. At breakfast afterward, she denies Harry’s suspicion that she has been with Vaughan, concealing the session from her friends. 407

House-Elf Advocacy and S.P.E.W.

Hermione proposes a campaign for house-elf freedom, arguing that centuries of enslavement have normalized their treatment. Seeking Vaughan’s support, she is unsettled when he asks her to consider the elves’ frequent resistance to emancipation and presents observational records suggesting that long-term selective breeding has affected their bodies and behavior. 371

She asks whether a potion could reverse these changes. Vaughan explains that a temporary physiological intervention would not necessarily change inherited traits, and encourages her to treat reversal of artificial selection as a long-term research problem. Although initially discouraged, Hermione regains hope when he promises to support her work. 371

After Hokey warmly welcomes her request for food, Hermione begins adopting a less coercive practical approach. She tells Harry and Ron that she oversimplified the issue, thanks Harry for supporting her, and suspends S.P.E.W.’s activities while retaining her underlying concern for the elves. 372

International Exchange Preparations

Hermione joins the intensive etiquette training arranged before Hogwarts receives its foreign delegations. McGonagall corrects her overly forceful recitation, illustrating that academic knowledge alone does not cover every aspect of representing the school. 373

When Harry learns that foreign wizards may challenge him because of his reputation for defeating a Legendary Wizard, Hermione rejects Ron’s proposed evasions and urges serious training. She subsequently earns top marks across the professors’ assessments. At the delegations’ arrival, she again acts as the practical voice of restraint, warning that hexing the Beauxbatons witch who insults Harry would worsen the public confrontation. 376 378

Her growing friendship with Cho introduces her to Chinese culture. Vaughan suggests that she become Hogwarts’ liaison to the Central Refining Academy, a possibility that excites her; the suggestion is not yet established as a completed appointment. 392 394

Forbidden Forest Investigation and Battle

Hermione leads Harry and Ron out of the Great Hall under Harry’s Invisibility Cloak to follow Lucius Malfoy, Snape, and their companions. She recruits Fruit Tea, whose animal network and knowledge of secret routes guide them toward the Forbidden Forest, then uses infrared vision to locate the adults. 386

By enhancing the trio’s hearing, she helps them overhear a meeting between English pure-blood representatives and North American wizards. The conversation exposes an effort to resurrect Voldemort, but the negotiations collapse into a violent battle. Harry’s reaction to a Killing Curse exposes the trio, and Hermione realizes that the castle’s Anti-Apparition protection prevents an immediate escape. 387

As Jason Hastings pursues them, Hermione turns her studies into practical combat. She reads the incoming attack through the Multispectral Vision Charm, reflects his Exploding Charm with a precisely timed Perfect Shield Charm, and then blinds and incapacitates him with Lumocecuren. Her success protects the injured Harry and frightened Ron, while Vaughan and Dumbledore observe from a concealed flying carpet. 388

Divided Loyalties During the Potions Exchange

Following the forest incident, Hermione’s relationship with Harry and Ron remains strained. A conversation at the Ravenclaw table briefly offers a chance to reconcile, but Ron’s resentment of Vaughan provokes another argument. 392

During a meeting break, Vaughan lets Hermione overhear Umbridge threatening the boys after their involvement in the Abraxan incident. Hermione is shocked by their actions and agrees to keep watch over them while Vaughan is occupied. He also reveals that he and Dumbledore had anticipated and monitored the developments. 394

Fleur’s attempt to approach Vaughan through Hermione produces another personal conflict. At dinner, Fleur presents her request as an opportunity to strengthen relations between Beauxbatons and Hogwarts, but Hermione reacts angrily and leaves upset. Cho stands with her and offers comfort, while Harry and Ron misunderstand the exchange as a romantic contest. 397

Hermione deliberately makes mistakes in the transformation-potion selection assessment, sacrificing her opportunity to join the formal exchange in an effort to keep Harry and Ron away from Vaughan and Dumbledore. She quickly remedies her own potion’s uncontrolled hair growth with an antidote. 401 402

When the boys explain their plans, Hermione pretends ignorance, concealing her recent contact with Vaughan and her knowledge of the adults’ arrangements. “The Deceiver” Personality Armament helps her maintain the lie. Despite this deception, their teasing and shared laughter briefly ease the trio’s tension, and Hermione restores their transformed bodies. 402

She remains disappointed about missing the exchange but accepts the selection outcome rather than requesting special treatment. Her role as Vaughan’s assistant nevertheless continues to give her access to his work and considerable freedom during the event. 405 435

The boys later exclude her from their attempt to enter the headmaster’s office. Ron would prefer to involve her, but Harry expects that she would try to stop them, even though he does not believe she would expose their actions. 455

Hostile Press Coverage of Vaughan

As the Daily Prophet’s coverage turns overwhelmingly hostile toward Vaughan, Hermione and Ginny attract attention from other students. Hermione reads the reporting critically, suspects that important circumstances remain hidden, and nevertheless acknowledges that Vaughan has angered many people. She plans to seek him out at the laboratory that evening rather than relying on the newspaper alone. 475

Hermione supports Ginny, who is distressed by the attacks and resolves to become a reporter or editor to challenge future slander. She reassures Ginny that Vaughan likely has reasons for his actions and deserves their trust. At the same time, Hermione remains somewhat distant from Harry and Ron after discovering that they have been acting behind her back. 475

Renewed Diary Search and Expanded Investigation Team

After Harry discovers that Voldemort intends to recover the Diary and use it to return, Ron finds Hermione in the library and asks for help. He reveals Harry’s deliberate lowering of his Occlumency defenses to look into Voldemort’s mind, the soul fragment inside Harry, and their belief that Snape is guarding the Diary. Hermione is angry at having been excluded from such a dangerous plan, but recognizes that the emergency requires more capable allies than the trio alone. 480

She recruits Fruit Tea, then accompanies Ron through the hidden passage beneath the Whomping Willow. Her knowledge of how to immobilize the tree and open the entrance reveals that she has kept secrets of her own. They reach Fred and George’s secret base, where the twins tease her as “the boss’s lady” before agreeing to help. 480 481

When the expanded group meets Harry and Hagrid, Hermione defends the decision to bring additional help. After Harry explains the search for the Diary and the uncertain leads involving Colin Creevey and Peeves, she proposes looking for both suspects. Ron divides the work, assigning Hermione and the twins to search for Peeves while he, Harry, and Hagrid look for Creevey. Fruit Tea leaves to mobilize the school’s pets and owls as an information network. 481

Hermione initially intends to let Harry lead, in accordance with Vaughan’s wishes and the larger plan she knows about. When Harry and Ron’s argument leaves both unable to remain calm, however, she takes control. Unable to rely on the twins for a useful plan, she puts herself in Harry’s position and determines their next move as though she knows nothing of Vaughan’s arrangements. 490
