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

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

• 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. 237 249
