Ok, so this was something I was playing around with last week, but chickened out. For Hannah, I definitely think she's an FP, the Fi is shown through her need for an authentic identity (quitting her job when it didn't align with her image of herself, and more importantly, to make a display of it), and her need to speak her mind when anyone speaks against her personal values. I also think her Fi was nicely contrasted with Mimi-Rose's Fe in the episode last week. However, I've been questioning whether or not she's an Se user. I don't think she's an INFP, because she is way too impulsive and she loves picking "intellectual" fights with people and is not afraid of conflict. I think Se because she is in the moment impulsive, like in this weeks episode where she instantly decided to go with a student to get a piercing between classes, or ditching on her graduate program. NFPs are known for their difficulty with making decisions, and although Ne is impulsive (especially ENXPs), they would at least take the time to determine whether there were better actions or ideas to take. Hannah though, seems to jump at any opportunity, be it a new job, drugs, a party, going to grad school, leaving grad school, or taking one of your students to get a piercing, she's never stopping to suggest a better idea (even if it's crazier). Finally, what originally made me think Se for her was her writing when she was at grad school. I can't really remember if we've had other large portions of her writing in earlier seasons, but I thought the story she read to her class was very sensory. It was graphic, descriptive, and focused on one scene, and the reactions from the class was that she was a bratty exhibitionist. It reminded me a lot of one of my ex's writing who was ESTP. Anywho, I can possibly see her as an ENFP, but I'm throwing SFP out there, and I could see her argued as either ESFP or ISFP, but INFP is seeming less likely to me. I still see Lena as an NFP, so I think some of that might seep in to Hannah's character, but maybe Hannah is her Se alter ego. Thoughts?
