Functional Order: Ne-Fi-Te-Si

The Doctor’s first approach to any new experience is excitement at its greater potential. He rarely takes objects for what they seem to be, but instead looks past them to their conceptual worth. He’s very quick to form accurate suspicions and discern others’ motives, and can even predict events in the short term (he realizes people are breathing in stone dust, which is converting them into a new kind of creature; he warns a woman  that she is no longer necessary, a second before her employers kill her as “the only witness”; he swiftly figures out the robots are waiting for Madam Pompadour to get “the right age” to harvest her organs, etc). He’ll often assert a statement and contradict it a moment later, indicating his ability to think in different directions at once (“No, it’s safe… well, maybe not safe … yeah, I think I’ll do a scan, in case there’s something dangerous out there…”). He can be oblivious to other people’s feelings, when absorbed in his own – so much so his companions often have to tell him he’s being rude to get him to stop (usually he’s so excited about an idea, he doesn’t quit theorizing it in time to avoid making it an insult). His preoccupation with losing Rose makes him clueless about Martha’s gigantic crush on him. It’s a relief for him to partner up with Donna, because she doesn’t demand he open up emotionally. When asked about his former partners, the Doctor admits they’re “gone… but fine,” without expanding on his feelings about it. He broods. Intensely. He also tends to see the world in strong ethical terms, defined by right and wrong; right is whatever he decides, and he can be merciless and without pity in punishing anyone who violates his stance on humane behavior. The Doctor can shut down and go into a Ne/Te loop, whenever he has to make a tough decision; Donna berates him for intending to let everyone in Pompeii die, because the Doctor argues “it’s a fixed point in time” – it must happen. He chooses to accept his role as the catalyst for making it happen, because “it’s Pompeii or the planet… that’s all I needed to know.” The Doctor doesn’t like it when others violate the “code of the universe” (disobey galactic rules) and often reacts with harsh punishment (imprisoning aliens in mirrors, destroying the spider’s children, etc). Donna says, upon their first meeting, that he “need[s] a companion, to hold [him] back sometimes.” Sometimes, if he lacks the tools to fix a problem, he thinks they’re doomed. Ten is running away from his past. He prefers not to think about, or dwell in it, too much, as it brings out his sadness over losing former companions, including Rose. When reunited with Sarah Jane Smith, the Doctor happily revisits their former connection, and even builds her a new K9 as a parting gift, making sure to give it all the memories of the previous model (inferior Si).

Stay in one place very long? Nope. The Doctor flits between worlds, always chasing something newer, better, more interesting, to escape his tortured past. He wants to absorb himself in new ideas, to find new creations, to discover new races and life. He’s witty, social, and engaging, making friends wherever he goes, always on the run and reluctant to commit or deeply think about the people he has lost. The Doctor’s focuses on protecting and guarding those who need his help, taking responsibility for the welfare of earth and trying to inspire its populace to greatness. His 8 wing becomes aggressive and domineering under stress, often asserting himself as the boss and demanding others step aside and do what he says. Under stress, the Doctor falls into unhealthy disintegration to 1, becoming rigid, punishing those who thwart him in increasingly harsh ways (locking them in mirrors, drowning a spider’s thousands of children, and causing Donna to say, “You need someone to stop you”). He never apologizes for his anger.
