I think, could you really see her with an SLE as a dual? I think she would bump heads with one, because she is their mirror. She seems like the introverted version of an SLE, thus making her rational, Se creative.
"If you really want it, if your willing to work that hard, its all about determination, you have to be able to achieve it and you have to be able to work hard for it" Creative Se.
"even if you want to walk around naked, I'm one of those nudist people". Beta, lol, just jokes.
"I speak just to not feel shy. Its really important even if they want you to be you yourself, and behave naturally". Fe suggestive.
"I'm not one of those people that goes on other peoples opinions about what I should wear, if I feel good in it I will just wing in and go on my gut instinct". LSI
And just anecdotally, the "eye popping out" emphasis while speaking thing I've noticed many times with beta STs. Cara does it all the time.
I think a tricky thing here is that sometimes the suggestive function is mistaken for 1st or 2nd functions, especially suggestive Fe. The same phenomenon can be seen with LIIs. There is a vast difference between an expressive person and a person who is an Fe ego. An Fe ego is adept at being someone who will act as your "emotional interpreter" in your relations with other people. Both Beta STs and to an equal degree the Alpha NTs require this to dualize.
