MBTI Type: ESTJ
Narcissa never entirely believes in the Dark Lord’s cause and betrays him, given the chance to find her son and rescue him from almost-certain death. When he sets her son a task Draco is certain to fail, she (presumably accurately) perceives that this is his intention, to punish her and Lucius for their failures, and demands Snape make an unbreakable vow to protect him. She can be caustic and rude, refusing to spend her money at an establishment that includes the “wrong sort” of people. She shares the same biases as her husband, and intends to uphold traditions that have gone away in the Wizarding World, such as an emphasis on blood purity. Narcissa is shocked and horrified that Dobby would use his wand against his former master. She is not as eager or as blind of a follower of Voldemort as her husband, and admits to Bellatrix and Snape that he may “be wrong” about certain things. Her entire focus, in what little we see of her, is her family and her son. She trusts Snape where her sister does not, because in her eyes he has proven himself through all Draco has said about him. She hopes Snape will take on Draco’s task and finish it, if “he cannot.” Narcissa shares the insight that in her opinion, the Dark Lord has set her son a task “he cannot complete, as punishment” for his father’s mistakes. She may also suspect Voldemort’s downfall, in her choice to take her son away from the battlefield once the fighting starts. Under stress, she becomes highly emotional, refusing to listen to her sister’s insistence that they not visit Snape or trust him, and begs him to save her son and protect him at Hogwarts. When push comes to shove, she protects her son, whom she dotes on, ahead of a war she does not care anything about.
Enneagram: 6w5 so/sp
Narcissa is hard to get a fix on in Enneagram terms, since she has so few consistent appearances in the canon, but above all, she is family-focused and aware of danger. She alone suspects Voldemort intends her son ill, and begs Snape to do something about it—trusting in him, while distrusting the master she has sworn to protect and serve. When it comes down to survival, Narcissa remains skeptical of her master and trades her belief system for her loved ones. Where her husband resists turning over his wand to Lord Voldemort, she convinces him to do so, knowing a refusal is death. She can be emotionally reactive, but also detached—sizing up what they are up against at Hogwarts and choosing to walk away.
