Extroverted Sensing (Se): Whatever she is doing, Bellatrix likes to be in the center of the action. This especially involves actual fights; Bellatrix revels in dueling her enemies, especially when she fights two or three at once. She has extremely quick reflexes, and she will continue fighting with any other weapon she has after losing her wand. Bellatrix is charming enough to talk the authorities out of imprisoning her after Voldemort’s first downfall, but she is so impulsive in trying to bring him back to power that she ends up in jail anyway with no hope of legal acquittal or social rehabilitation. Bellatrix savors every moment, and always likes eyes on herself, even during her trial, when it was clear that it would be a long time before she would be out of prison. She is always quick to think of something to say, especially when voicing her willingness to further Voldemort’s cause.
Introverted Feeling (Fi): The only feelings that matter to Bellatrix are her own, Voldemort’s, and possibly those expressed by members of her family. She could care less about anyone else, and she will torture people purely for her own enjoyment. In fact, her explanation for why Harry can’t use an Unforgivable Curse properly is that he doesn’t take enough pleasure in using one. Bellatrix distances herself from her own sister when she falls into disrepute (among Voldemort and the Death Eaters), and takes it so personally when Harry says Voldemort’s name that she is willing to jeopardize her assigned task to lash out at him. Bellatrix’s loyalty to Voldemort is highly personal, and it is ironically humanizing for her master; for all the “greatness” that she sees in him, she still sees him as a fallible human being, and she is one of the few Death Eaters who will try to point out his mistakes.
Extroverted Thinking (Te): Bellatrix is extremely loyal to Voldemort, but it usually comes out in her actions (offering her help, fighting for him, etc.) rather than in her words. Her personal feelings are expressed likewise; to express anger or frustration, she will jinx (often random) people. Bellatrix has doubts about Snape’s loyalty to Voldemort, and she attempts to resolve her doubts by asking Snape direct questions about specific things: his actions around the time of Voldemort’s first downfall, why he never searched for the fallen Voldemort, and why he didn’t respond immediately to Voldemort’s summons when he came back.
Introverted Intuition (Ni): Bellatrix’s doubts about Snape’s loyalty, as it turns out, are not unfounded, no matter how many people don’t believe them. Bellatrix is so obsessed with bringing Voldemort back to power and so sure that he will come back that she is willing to wait a long time in prison for it to happen. When she sees Harry and his friends with the Sword of Gryffindor, Bellatrix has a paranoid meltdown, as she is supposed to have the sword in her bank vault, and she thinks that they somehow broke in and stole it.
