Ender’s Game Saga, Orson Scott Card
Other factors to keep in mind: PTSD
Si: She’s capable of holding long-term, committed grudges. She has an extremely difficult time letting go of pretty much everything from her past. Yeah, her parents died when she was a kid, but she never, ever, ever lets go of that. In fact, she lets it turn her into an icy, cold, and even hateful person (yet, she doesn’t show signs of PTSD). Her first impressions of Ender, she directly relates to Libo and her past experience. Though Novinha is an idealist, her practicality is her strongest trait. She’s practical enough to give up some of her strongest desires to protect people.
Te: In comparison to Novinha, Ender seems like an F dom, but in reality, they’re both Te users. From a young age, Novinha is filled with ambition that leads her to want to take control of Lusitania’s zenobiology department before she’s ready. She likes to be in control of her situation and lashes out at others when she feels she’s lost this grip. She cares more about results than process or feelings. Novinha’s relationships might better be described as contracts. She marries a man she doesn’t love in order to protect one she does love from finding out a secret that could kill him. She marries Ender for his compassion towards her children, and then rejects them for talking to Jane.
Fi: In response to her parents death, Novinha isolates herself, and her alienation only serves to give her a stronger, more penetrating presence in Lusitania. She holds perpetually to the belief that she is different from everyone else and that no one can understand her. She hates needing people, and over time, distances herself even from needing Ender. She’s angry her entire life –a raging, hateful anger that does little good to her family life.
Ne: When Novinha is under the most intense stress, she catastrophes about all the worst possible outcomes of the present situation, latches onto the most horrible one, and then believes firmly that it will happen.
