I had a thought yesterday, while I was writing something, oh not for my blog, this was for something else. But it occurred to me that there is one defining thing about the original series of 7 episodes which Patrick McGoohan had intended, that all the No.2's were seen outside in the Village, whereas the No.2's of the remaining 10 episodes were not. But then I had not taken 'Hammer Into Anvil,' It's Your Funeral,' and 'A Change of Mind,' into consideration, and then I dismissed my original thought, thinking I was onto something there for a moment.
Oh well it was worth a try Number Two!
Be seeing you
