I need some help, Gaangsters

I'm writing an AU where Yue lives and she goes with the Gaang as far as Ba Sing Se, but I am having the problem of not really having a clear grip on her personality. This makes it tricky to write her actually having scenes with the Gaang and Jet and other such folks.

(Note: the scenes with Jet aren't in the fic I'm writing but I'm trying to write them as a personality exercise and so not working.)

So! Thoughts on Yue, please.

Clarification: Thoughts on Yue's personality, please.
