Functional Order: Ne/Fi/Te/Si
Dominant Function: Ne
Enola is witty and inviting in her desire to interact with the audience. She is good at solving puzzles and understanding her mother’s cryptic meaning, relying on the methods her mother taught her to make sense of things. She solves her mother’s cryptogram, knows her brother has set a trap to get his hands on her (and evades it), and operates off her assumption about who sent a hit man to attack the young Viscount (she’s right about the motive but wrong about who is responsible). Halfway through her mission, she decides to change her focus entirely and pursue a new thread (the Vicount’s safety) since she realizes he is more important than her mother’s disappearance. Enola is naieve and too trusting of her rooms being good in London. She sees the big picture in needing to allow the Viscount to escape for his own safety.
Auxiliary Function: Fi
She is more wrapped up in her own feelings than she is in the Vicount’s case — she is so busy thinking about finding her mother and returning her life to normal that she doesn’t ask any questions about who is after him or why or if she should be concerned. She is preoccupied with her present problem, and leaves him alone in London to fend for himself. Enola has a fierce need to be true to herself and not pressured into being like anyone else. She has no interest in wearing a corset unless it is her choice (and serves a purpose in hiding her from her brothers). Enola becomes offended when her brothers poke through her mother’s room in their investigations and make disparaging remarks about her, and tells them to get out. She sasses her teacher and gets a smack and also splashes her bowl of soup into another student’s face. Enola helps the Vicount escape death because it’s the right thing to do, but refuses to tell him anything about herself and leaves him in London because that’s “part of the plan.”
Tertiary Function: Te
She prefers operating off a complex plan rather than winging it—but can do so under pressure, such as when she knows the only way to escape and survive an assassination attempt is to leap off a moving train.
Inferior Function: Si
Throughout the story, Enola references her previous experiences, the things her mother taught her, and flashes back to her recent memories as she strings together what is actually going on around her. She was content in her life in the country with just the two of them, odd though it may have been, and for awhile all she wants is to “get her mother back, so my life can go back to normal.” Ie, the way it’s always been.
