The Holocene Mass Exinction Event

i'm sure i've re-read it since finding out about its origins, but i've still never seen here come the brides so the characters are pretty much still the book characters in my mind. i was thinking about it because i was looking for some mark lenard clips on youtube and there was an episode of here come the brides up which i tried watching but it was waaaaaay too dull. but i noticed some things about how aaron's clothes were different deom everyone else's, and the makeup people kept him looking pretty dark and semitic in comparison to all the square-jamed blond heroes, so i was wondering, especially since i've heard that aaron is supposed to be the "villain" of the show.
