 In the original script of the pilot, there was a subplot in which it  is revealed that Kane had once been one of Dr. Huers students. This  is alluded to when Ardala comments, "Youre from Earth, Kane...".  Also, in the original script, during the reception for Ardala in the  Inner City, there is a bantering conversation between Huer and Kane  where he hints that he has progressed far further under the  Draconians than Huer would have allowed him to.
