Lucy Carlyle’s MBTI type is one of the most debated aspects of Lockwood & Co. In the Netflix adaptation, portrayed by Ruby Stokes, Lucy shows strong traits of an ISFJ personality type and aligns closely with Enneagram 6w7. Her emotional sensitivity, loyalty to others, and deep connection to past experiences make her a compelling example of an ISFJ 6w7 navigating a dangerous, unpredictable world.

Introverted Sensing

When Lucy Carlyle first arrives at Anthony Lockwood’s home, she is surprised he is doing things differently from what she expected. She expects him to have parental supervision because that’s how she grew up inside DEPRAC-authorized training systems. She expects him to have the right credentials, and lies about her own, because she never finished her level four exams and believes that because every other agency turned her down, he will as well. These expectations come from being aware of how the DEPRAC system works, what expectations are required from youthful recruits, and from her own personal experiences. It irritates her that Lockwood forgets things, like iron chains, when going into dangerous situations. She is very attentive to their safety and monitors things like the iron filling circle (“Careful, you broke the line!”).
Throughout her experiences working with him, Lucy is haunted by what happened to her and her friends in the situation where her best friend became ghost-touched (and is now in a coma). She replays these incidents in a memory-driven way. When she connects to the ghosts, she also replays their experiences through a combination of what she sees in a vision state and by drawing what happened from their emotional-memories. Her attentiveness to detail is also minute; she notices a ring on a skeleton’s finger and takes it with her out of the room, even if she doesn’t fully understand her need to do so.
Unlike Lockwood, Lucy wants to know what to expect going into unfamiliar situations. In the books in particular, when they are pitched the idea of going to Comb Carey Hall and dealing with a ghost, she thinks they will need time to discuss it and decide, and is shocked when Lockwood says yes on the spot, because it won’t give them much time to prepare or research details. Lucy eventually quits working with Lockwood for a short time because she doubts he can keep them safe, given her negative experiences working with him and George Karim. But she also rejoins his agency later, when she changes her mind.
Extraverted Feeling
Lucy is highly receptive to other people’s emotional states; in the first episode’s opening case, she instantly starts feeling what the ghost was feeling, just from being around her. In the book, it goes into more detail about how she can feel and sense the anger, confusion, and rage swirling inside of the spectral being. Lucy easily connects to and sometimes gets sucked into the ghosts’ feelings, including becoming so immersed in holding the ring and focusing on it she acts out what happened to the murdered girl with Lockwood (becoming romantically affectionate toward him, then feeling intense pain and anger as she “dies”). Lockwood warns her many times that she has to stop automatically being pulled into these emotions, since it could compromise her judgment, but it’s hard for her to shut them off. She unthinkingly stole the ghost-ring and took it to her room because she wanted to know more about these feelings. Later, she connects to the ghost jar.
As soon as the spirits in Combe Carey Hall become active, she becomes disturbed by the victims and their emotional weight. Lucy also becomes emotional in court when her former supervisor is telling lies to conceal his cowardice, and lashes out at him in public. She quickly voices her true feelings to Lockwood and George, asserting that she is angry at them and inviting George to get up off his armchair and “take this outside.” She does not like to be made to feel invalidated, unsafe, or made fun of, and she leaves Lockwood & Co. because she does not feel emotionally supported and safe.
She often seeks reassurance and understanding from Lockwood, who is more emotionally available than George, whose detachment irritates her. Lucy also has a slight problem with the idea of “experimenting on” the head in the jar, since she frames that in moral terms (can it feel pain?).
Introverted Thinking

The few times she argues with Lockwood, Lucy winds up pointing out where he is being reckless and needs to be more careful. She understands she cannot allow her own feelings to compromise her logic or her safety, but cannot prevent herself from being drawn into other people’s problems. Lucy also wants to find out what happened to the ghost; how she was murdered, who did it, and for her to find peace and not just be destroyed. She asks questions like, what kind of ghost this is, what its source might be, what the rules of engaging with it are, and interacts with it based on what she learns.
She notices in the books how quickly Lockwood changes his mind about things, such as wanting the locket (a ring in the series) destroyed, until he realizes it could be their ticket to fame and fortune if they use it to solve a decades-old murder. Lucy also slows him down by asking if they actually know what happened and if they are wrong about the source. She is checking to find out if what they know makes sense and is holding out in reality, or if they need to think in a different direction. Lucy also defaults to wanting to withdraw and decide what the safe move would be when things go wrong.
Toward the end of the first season, Lucy becomes increasingly focused on finding out what the Bone Glass is doing, what its purpose is, and how it works. She wants to understand it, rather than simply destroy it, and she pieces together its effects and risks through analysis.
Extraverted Intuition
Lucy starts talking to the ghost head in the jar, but she does not have strong enough intuition to know when he is intentionally misleading her; he almost tricks her into freeing his previous master from the spells that bind him to the basement.
She feels “something” is attached to the possessions she removes from haunted houses, but does not realize they are cursed or will bring the ghosts home with her. She takes the ring with her away from the house, encased in a locket around her neck, and prevents it from being stolen; she didn’t know why she felt she needed to have it with her, or why she feels so connected to it.
Lucy is anxious and fearful about the unknown, wanting to be prepared rather than to go into dangerous situations without proper planning.
As she gets more and more entangled with her first ghost and in solving the murder, Lucy theorizes on who killed her, what his reasons might have been, and how they can bring him to justice.
The Enneagram 6

In the first flashback, when her fellow students enter a haunted mansion, Lucy tells them not to push forward, that they need to fall back and regroup, because she feels that the presence in the house is evil. They ignore her and go to their deaths; she runs outside to beg their supervisor to come with them and “give his opinion.” This is outsourcing to an authority, something 6s do when stressed. (I need you to come with me and tell me it’s safe or not safe or what we should do!) He tells her to solve her own problem, so when he enters the mansion and then turns tail and runs, leaving his students to die or be ghost-locked, she angrily confronts him in court and winds up being fired. She hates it he got away with it and was not held accountable. 6s resent incompetent authority figures and respect people who seem to know what they are doing; Lockwood earns this respect until she feels unsafe, and then she pulls away from him and looks for a different job.
Even though Lucy is far more talented with her “Talent” than everyone else, she is not arrogant, does not trust it, and does not understand why Lockwood puts so much emphasis on it. She is cautious and prefers teamwork to asserting herself, though if George pushes her buttons, she will ‘react’ on an emotional level, escalate, and put him in his place (threatening to fight him, if he doesn’t shut up).
She is often fearful and watching her back, but is also ready to put her life on the line for her friends. She wants to give up at one point and retreat, but when Lockwood insists on going into a dangerous situation, Lucy goes along with him out of a sense of loyalty and the idea that at least she can watch his back, a classic 6 move of “well… this is stupid, but we’re safer together than we would be apart, and if I let him go without me and he died, I would never forgive myself!”
The 7 Wing
Lucy has a good sense of humor and is always making fun of things. She also asserts herself easily and confronts people when necessary, who want to demean her, showing that she engages with others rather than withdraws from them (George, a 6w5, does the opposite; he will instigate an argument and pull back, whereas she will push harder). She will take risks with her friends, despite her anxiety, and has an overall hopeful anticipation that things can work out even when they look bleak.
