As I mentioned in my last post, which is at the bottom of the previous page and was probably skipped over... I don't see why T'Ryssa has to be played by an Asian actress. If she's Vulcan and she bleeds green, and she has black hair, then they could use makeup on whoever they would pick. I don't know that they would need to start with a Chinese face. Would they? I originally thought her Chinese half was apparent (reading GTSS), but now it is clear that everyone confuses her with a full Vulcan (LtP).
