'Living In Harmoy' is my least favourite episode, but if I'm to choose a favourite scene, it would be the gun fight between the newly appointed Sheriff and the Kid.
In this episode Number 2 achieved something that Number 2 in 'Once Upon A Time' failed to do, and that is to make Number 6 kill! Also in the Man with No Name having been appointed the new Sheriff of Harmony, could be seen as a metaphor of when Number 6 was selected as the new Number 2 of The Village.
The Prisoner must be keen on resigning, it seems he cannot hold a job for more than five minutes. We witness the Prisoner resigning at the beginning of 'the Prisoner,' and in 'Living In Harmony' we witness the Man With No Name resigning his job twice!
If you watch the film footage you will observe that the Kid actually beats the Man With No Name to the draw, and yet it's the Man With No Name who fires his colt 45 Peacemaker first!
Be seeing you
