Background / History

Cassandra first encountered Wentworth in Diagon Alley before beginning at Hogwarts. A rejected dream-communication Paper Crane landed in Wentworth’s hands; when he bought it, the crane’s activation bound them to share dreams based on what was written upon it. She introduced herself as the “future pride of Slytherin,” displaying an early fixation on being sorted into that house 7.

She entered Hogwarts as a Slytherin and was already notable for her confidence, aristocratic bearing, and magical talent. During the first-year inter-house duels, she represented Slytherin and fought second-year Cedric Diggory to mutual exhaustion, earning recognition as the strongest first-year Slytherin 15 40 45 48.

Cassandra’s family became entangled in a crisis surrounding her father, Thomas Levo. After receiving secretive correspondence, she used a concealed passage from Hogwarts to reach him; she found him captive and later witnessed Christine’s associates torture him with the Cruciatus Curse to coerce her cooperation 98 129 135. Under pressure to save her father, Cassandra attempted to lure Wentworth out of Hogwarts, but her guilt and growing feelings for him repeatedly undermined the scheme 133 134 137 155.

After Wentworth protected her family despite suspecting her involvement in the plot against him, Cassandra openly sought to become his follower and join the Acolytes. Wentworth refused because of the attention a Slytherin openly following him would attract, but Cassandra vowed to follow in his footsteps regardless 143 157.

Appearance

Cassandra is a young witch with golden curls and striking emerald-green eyes. She is presented as elegant and carefully composed, though emotional strain has at times left her visibly pale or exhausted 144 171 227.

• Golden curly hair 144 455
• Emerald-green eyes 144
• Later seen wearing dark-green glasses 455
• Usually wears light makeup and is conscious of her appearance 133 171
• Used a broomstick marked with a pink bow during her first flying lesson 49

Personality

Cassandra is proud, ambitious, and intensely competitive. She values Slytherin dignity, dislikes sycophancy, and reacts sharply to humiliation or perceived disrespect. Her confidence is supported by genuine ability; she does not hesitate to challenge stronger opponents, including Cedric and Wentworth 26 40 45.

Behind her haughty manner, Cassandra is emotionally vulnerable and deeply devoted to those she accepts as her own. Her father’s captivity left her frightened, guilty, and susceptible to manipulation, yet she continued trying to protect him. Wentworth’s kindness—particularly his Paper Crane message and Firebolt gift—gradually broke through her guarded exterior 135 137 144 155.

She is also highly proactive and politically minded. Cassandra repeatedly interprets Wentworth’s intentions, builds structures around his goals, and takes responsibility for expanding his influence at Hogwarts. However, her determination can become overbearing; she initially tried to bear the Secret Society’s burdens alone and was reminded by Green that leadership required trust in her partners 172 179 209 213.

Family coercion

Following the attack on her father, Cassandra is pressured into luring Wentworth into danger. She tries to conceal her situation and manipulate him, but her distress, attachment to him, and refusal to directly harm him complicate the mission 98 129 133 135 155.
