Extraverted Intuition (Ne): Molly can typically read behind the lines where other people are oblivious. She picks up on subtleties in people’s behaviour that most people miss and comes to conclusions about their inner states of being. Molly relies primarily on intuition to figure things out even though she doesn’t always put two and two together logically. Because Molly has such a good understanding of people, she easily accepts and forgives the flaws of people very different from herself. She’s good at keeping other people’s secrets, albeit not necessarily her own.
Introverted Feeling (Fi): Molly is an empathetic person who cares deeply what other people are feeling, even if her interpretation of their feelings is often largely inaccurate. She’s incredibly affectionate, always willing and ready to help out anybody in need. She’s open about her feelings and personal life to the point of awkwardness and she frequently embarrasses herself by speaking her feelings too directly. She often asks Sherlock how he’s doing despite experience telling her he won’t answer, and still loves him when he calls her the wrong name and treats her like crap.
Extraverted Thinking (Te): Molly makes plans and organises her life, but at the same time, she’s totally willing to drop everything at the last minute and help Sherlock out with a dead body or what not. She doesn’t always pay close attention to evidence and as a result, doesn’t always notice what’s obvious to everyone else (such as the fact that she has absolutely no chance with Sherlock).
Introverted Sensing (Si): Social graces are important to Molly, and she’s often deeply hurt by Sherlock’s lack of them. She often relates current conversations to the past (for example: comparing Sherlock to her Dad).
