Look at this screen first...
Ok, I know your all saying "what the crap is this noobs problem!?!" but please hear me out...
I know in the screen she looks evil and the best guess is that she is out to kill the pc, but...
In the main trailer (Lucas Arts KotOR II I'm sure you can find it elsewhere but I had the LA page opened...) about 2/3's through there is a short scene were you are fighting the same black clothed/hooded guys, and the girl in the tan robes (arabian looking) or someone who looks a whole lot like her is fighting them with you... maybe shes not your padawan but I just thought this was interesting were she is portrayed to be so evil in the screen
