In The Gamesters Of Triskelion, how many disembodied brains exist on the planet? I seem to recall after the landing party gets their colours, Galt said something like "red, you are on a good team". However, at the end we are only shown 3 disembodied brains. It would be a very strange way of talking to say "you are on a good team" if there are only 3 teams. However, I may have been mistaking as I couldn't find anyone saying "they have a good colour" anywhere in the transcript.
In any case how many brains are there, do only 3 brains make up the entire race?
