There is a old man in this episode whom is know as Mr. Atitios in the episode All Our Yesterdays. I know its the same actor but is it the same character? Many of the Trek actors appear in more than one episode I have noted but this actor I am not sure.
So apart from many 60s actors guest-appearing more than once on Star Trek, what would cause you to think Ian Wolfe might have played the same character in these two episodes? They didn't act the same way, both lived on two different planets...heck, at the end of All our Yesterdays AtoZ ends up in the past!!
This thread is perplexing...
