But she's a side character and they only showcase her specifically during her big Fe moments.
Interestingly, there was no problem diagnosing Wilson or Foreman as introverts. I don't see that this is a legitimate argument. Yeah, we don't see as much of her. We also don't see as much of Foreman or Chase either (well Foreman recently, but I've known since before the new seasons). Still there's no question.
She could well be an introvert with an Fe auxiliary. We just only ever see Fe.
Why don't we extrapolate that another step or two: We might only ever get to see her when she's wearing her Cameron suit.
She could be an alien or black or even dead!
But we know these things aren't true, because we know that, among other things, the writers and directors and actors try to put the most representative foot forward to make it so we can 'fill in the blanks'.
It's a certainty that she's a contrasted character: she has ups and downs.
Fair enough, that's fine, but there's very little passive aggression in television, so either we work with what we've got or we don't bother at all.
Assuming there is evidence to the contrary of E but we don't really know about it except from 3rd person omniscient standpoint in the hypothetical: what sense is there in using that data? We don't know it's there. We just guess. And yeah, speculation based on prospective data is great (it's especially evidenced in this very show: House speculates without having the concrete data plenty, and demands that they search for the information to confirm it) but since the data is impossible to ascertain it's worthless.
It's like
"I have $150 in the budget to save seals. I won't spend the money anywhere else."
"It costs $300 to save 1 seal"
The money can't do anything then.
Seems like things we've definitely seen are a bit more reliable, but then I don't know what your religion is, so I don't know what you're willing to believe.
I'm taking into consideration her level of reserve when she's not having some ethical blow-up.
Which isn't a great lot: She's often the first to speak up in the differentials -- she willingly and deliberately manipulates people and possibly the crown jewel of the argument, she,
even despite her obvious fear and intimidation insisted House tell her his feelings of her.
If that's not Fe over Si/Ni then no E_FJ exists.
