Background / History

Snape was already Hogwarts' Potions Professor and Slytherin Head when Dumbledore tasked him with receiving Cyberlina Sekerei and escorting her to the school. Though openly reluctant, he completed the assignment and later accompanied her to recover research notes and her wand from her former residence. 1 2

Dumbledore subsequently showed Snape a memory concerning Cyberlina's past and warned him that her kindness and popularity could conceal manipulation. Snape recognized her deliberate testing of his reactions after instinctively using Occlumency to hide his emotions. 3

Lucius Malfoy's memories later reveal that Voldemort had ordered Snape to serve as a spy beside Dumbledore. Dumbledore is aware of this history, while Snape continues to keep much of it concealed. 40

Snape's longstanding hatred of James Potter and desire for revenge remain a major emotional burden. Cyberlina confronts him over this hatred and urges him to consider what purpose his life might have after Voldemort's defeat. 34

• Wears black robes. 1
• Often has a grim, blank, or dark expression. 14 20
• Uses a cold, intimidating gaze when suspicious or angry. 11

Personality

Snape is sarcastic, guarded, and easily irritated by what he considers foolishness. He is especially blunt toward Harry Potter, Cyberlina, and Dumbledore, frequently responding to them with cutting remarks rather than open agreement. 11 20 43

Despite his harsh manner, he is responsible and protective when students are in danger. He shields Harry from a snake-statue trap, reprimands Cyberlina for making Harry cast the Cruciatus Curse, and acts quickly to prevent Fred and George Weasley from falling onto enchanted armor. 14 15 35

He is highly vigilant about manipulation. Snape recognizes Cyberlina's attempts to influence him, remains suspicious of Dumbledore's motives, and relies on Occlumency to suppress strong emotions. 3 11 25
