She screams ENFJ to me. She isn't bubbly enough to be an ESFJ. She values things mostly only NFs would value: intellect, indentity, self-worth, etc. She takes her job seriously and said herself that she doesn't "fuck around." Her demeanor is that of grace and wit.
She doesn't use as much body language as much as I would expect an S to use. She doesn't and nod her head and use her hands to show how enthusiastic she is about something.
I also feel that she always knows the right words to say, like the hurricane interview. I believe that this is a gift given to ENFJs. The ability to detect and use their N side to come up with the perfect response.
Also, as Lookin4theBestNU stated, she is reluctant to accept compliments. ESFJs STRIVE off what other people think of them. They need constant reassurance and reminders that they are liked, are helpful, and needed. Reese just has too much drive in herself to be considered like that. Let's face it-- ESFJs are not as independent. Reese is.
