I will admit to having a crush on her myself. Her first episode was a sort of stock tough girl shows the tough guy a thing or two. It was well done, but not surprising. That said, even near the end of that episode she was already shown as a bit deeper than the average tough girl. I enjoyed the episode and enjoyed her work.
She quickly became a deeper character. With the season ending two parter, she just about stole the show. Excellent work. I think I stated somewhere else how fantastic I think she is in the show. And yes, she’s absolutely gorgeous.
Regarding the above speculation: I really don’t know who it may be. Could be Fett, but I hope not. Not a fan of him post-TESB.
