Haven't we seen Nestor...?
Although his name does not appear in the credits, I have often wondered if the Nestor that is killed on Sador's ship was in fact played by Brent Spiner (Star Treks Data). The voice is remarkably similar and even the face I thought matched. His line about it being 'good to have skills' when he is about to be cut up by the doctor, I thought had a certain dead pan ring to it. The same way that he portrayed Data in the early series.
Anybody else think that? Maybe he used a different stage name when he was younger?
