Background

Snape taught Potions during Lin Du's earlier exchange year at Hogwarts. He remembered Lin as one of the few students who consistently earned Outstanding marks in the subject, while Lin remembered him as a rigorous, nearly harsh instructor who still corrected minor flaws in his work. 7

By the time Lin returned as Hogwarts' Defense Against the Dark Arts professor, Snape was established as the Potions Master and Head of Slytherin. He immediately scrutinized Lin's reasons for returning and remained wary of his reputation for defeating Aurors and researching Dark Magic. 7 12

Appearance

Snape is a pale, gaunt man whose habitual black robes and severe features give him a distinctly intimidating presence. 7 129

• Sallow or pale complexion. 7 129
• Greasy black hair and cold black eyes. 7 129
• Hooked nose and thin, tightly pursed lips. 129
• Typically wears flowing black robes, often compared by students to bat wings. 9 129

Personality

Snape is stern, private, and sharply sarcastic. He has little patience for recklessness, poor preparation, or imprecision, especially from Gryffindor students and in Potions work. 9 60 87

He is intensely proud of his expertise and reacts badly when he feels sidelined or underestimated. Dumbledore's permission for Lin to conduct controlled Dark Magic research provokes visible anger and jealousy, while the success of Lin's exam-preparation materials leaves Snape feeling isolated as Potions becomes the school's academic weak point. 12 87

Despite his hostility, Snape can act with professional responsibility and reluctant compassion. He tempers his usual response to Neville's potion accident, takes on the Defense Against the Dark Arts workload when needed, and brews a Revival Potion to awaken Lin from petrification. 35 59 62

Abilities & Skills

Potions Mastery

Snape is an exceptionally precise and knowledgeable potioneer, particularly in the control of difficult brewing processes. 7 120

• Prepared a Mandrake-based Revival Potion capable of countering Lin's petrified state. 61 62
• Was personally requested to brew Wolfsbane Potion because of its demanding requirements for heat, stirring, and ingredient timing. 120
• Sets unusually difficult Potions examinations, including questions on ingredient interactions and Wolfsbane Potion stability. 169
• Insists on personally grading assignments and critiques errors in extensive detail. 60

Dueling and Defensive Magic

Snape duels with speed, precision, and a ruthless focus on ending a fight efficiently. 36

• Uses rapid Disarming, Full Body-Bind, and Obstruction Charms, alongside darker curses. 36
• Maintains a dark, web-like defensive spell strong enough to threaten Lin during their simultaneous finishing exchange. 36
• His duel with Lin ends in a mutual stalemate after neither professor can safely secure a decisive advantage. 36
• Quickly neutralizes the Weasley twins' corridor prank with silent cleaning and ventilation magic. 60

Teaching and Discipline

Snape teaches with harsh discipline but considerable technical depth. 60

• Took over Defense Against the Dark Arts after Lockhart's removal and followed Lin's demanding practical syllabus. 59 60
• Gives clear, logically structured lessons on dangerous magic, including principles, variations, and countermeasures. 60
• Enforces consequences for misconduct immediately, including significant point deductions for the Weasley twins' prank. 60
• Struggles to sustain both Potions and Defense Against the Dark Arts duties simultaneously because of the practical classes, grading load, and lack of sleep. 60 61

Equipment / Items

• Wand — used for Potions-related magic, dueling, discipline, and defensive spellwork. 36 60
• Mandrakes — stored in his office and used as the key ingredient for a Revival Potion. 61
• Revival Potion — dark green antidote brewed to awaken Lin from petrification. 61 62
• Potions edition of Five Years of O.W.Ls, Seven Years of N.E.Ts — provided by Lin to support Potions instruction and revision. 120

Relationships

• Lin Du — Former student, later colleague, rival, and Duelling Club co-founder. Snape distrusts Lin's Dark Magic research and resents Dumbledore's approval of it, yet gradually acknowledges Lin's growth and ultimately brews a potion intended to revive him. 7 12 36 62
• Albus Dumbledore — Headmaster who entrusts Snape with major teaching responsibilities but declines to reduce his double workload, much to Snape's frustration. 60 61
• Minerva McGonagall — Fellow professor who pressures Snape into taking the vacant Defense Against the Dark Arts post, citing Hogwarts' immediate need for a capable instructor. 59
• Harry Potter — Snape regards Harry as reckless and likens him to his father. Dumbledore nevertheless identifies Snape as someone who cares deeply about Harry, though Lin finds this expression of concern difficult to recognize. 9 32
• Remus Lupin — Former schoolmate with longstanding tension between them. Snape agrees to brew Wolfsbane Potion for Lupin, though only after persistent pressure from Lin. 111 120
• Neville Longbottom — A student so frightened of Snape that his Boggart assumes Snape's form; after a classroom incident involving the Boggart, Neville becomes convinced Snape may poison him. 129 130
• Gilderoy Lockhart — Snape openly considers Lockhart incompetent and reacts with extreme displeasure to his appointment as Defense Against the Dark Arts professor. 55

Story Role / Major Arcs

Conflict with Lin Du

Snape's reunion with Lin begins as a polite but guarded exchange. His suspicion intensifies after learning that Dumbledore has authorized Lin's Dark Magic research within Hogwarts, exposing Snape's own unresolved feelings about Dark Magic and Dumbledore's trust. 7 12

Lin repeatedly teases Snape about his supposed concern for others, causing Snape visible distress and unintentionally creating a schoolwide reputation that Lin can restrain him. 34 35

Duelling Club

Snape co-founds the Duelling Club with Lin, using their opening demonstration to show students that dueling is about speed and effectiveness rather than spectacle. 36

Their duel displays Snape's aggressive, Dark Magic-tinged style against Lin's evasive defensive control. The confrontation ends without a winner, but Snape admits that Lin's growth is beyond what he expected. 36 37

Temporary Defense Against the Dark Arts Professor

After Lockhart is removed, McGonagall appoints Snape as the temporary Defense Against the Dark Arts professor—a position he had coveted for more than a decade. 59

Snape proves skilled and rigorous in the role, but inheriting Lin's intensive practical curriculum while continuing to teach Potions leaves him exhausted and increasingly irritable. 60 61

Lin's Recovery

Overwhelmed by the dual workload, Snape uses Mandrakes to brew a Revival Potion and brings it to the petrified Lin before dawn. Lin breaks free through a burst of accumulated magic before receiving the potion, knocking Snape unconscious; afterward, Lin identifies the spilled mixture as a genuine antidote. 61 62

Academic Rivalry

When Lin's Five Years of O.W.Ls, Seven Years of N.E.W.Ts revision materials improve results across most core subjects, Snape confronts him over Potions being excluded. Lin agrees to create a Potions question bank, leading Snape to reconsider how he assigns holiday work. 87 88

Notable Quotes

“Dueling is an activity defined by efficiency. When two wands face each other, only two things matter: who completes their spell first, and whose spell... is more effective.” 36

“Your growth... is unexpected.” 36

“Madman.” 50

Trivia

• Snape's long-held desire to teach Defense Against the Dark Arts is fulfilled only after Lin is petrified and Lockhart is removed. 54 59
• Neville's Boggart takes Snape's form, making Snape the class's clearest symbol of fear before the Boggart is transformed into a version wearing Neville's grandmother's clothes. 129
• Snape strongly suspects that Lin used unusual magic to explain Fred and George Weasley's sudden seriousness about studying Potions. 166
