Functional Order: Fi-Ne-Si-Te
Myrtle’s entire world revolves around her own thoughts, feelings, and opinions. Hermione calls her a “little sensitive,” but she’s a lot sensitive. She takes every slight, insult, and offhanded remark as license to flounce off, to scream at people, or to burst into tears. She can also be somewhat malicious in her enjoyment of others’ suffering, such as her cackling delight when Hermione uses Pollyjuice Potion to half-transform into a cat. Myrtle hates being alone, and invites Harry to share her toilet if he gets killed in the Triwizard Tournament. She can be self-preoccupied and rude, even abrasive and angry under pressure—falling into a lower tendency to tell people off for offending her or being in her bathroom. She tends to leap to conclusions and believe them, even if they are wrong (assuming that Harry is the one using Pollyjuice Potion, because she sees a bit of it floating past in the sewers), and is imaginative in thinking up the worst-possible outcomes, but spends most of her time in a Si loop. Ghosts do not remain in this world unless they were miserable at the time of their death—and she has clung to her misery and wallowed in it, for decades. She expects the same things to happen to her, over and over again (for her to be teased, made fun of, avoided, etc) and makes them come true by showing no genuine desire to change, get outside her comfort zone (leave the bathroom? Interact with the students as a “proper” Ghost?), or overcome the past.

Myrtle is the perfect example of a severely unhealthy 4 – she is entirely lost in her emotions to the point where she compounds her problems by being so dislikable, she alienates and puts off the very people she wants acceptance from, thus creating a never-ending cycle of abuse, rejection, longing, hateful envy, and misery. She magnifies every emotion tenfold, she combs back through conversations to find the insult and then overreacts to it, and she forces everyone around her to walk on eggshells for fear of causing her an emotional meltdown. Myrtle has no interest in fixing her problems, just in complaining about them – almost all her dialogue is wrought with anguish or resentment or rage, she often references her suicidal inclinations, and she shows a gleeful tendency to glory in other’s misfortunes.
