This led me into thinking just how important the reason behind the Prisoner's resignation is to No.2 and his Administration? After all only four of the 17 episodes of 'the Prisoner' actually deal directly with the question of why No.6 resigned. So it occured to me that the reason why No.2 persists with the question of why No.6 resigned, is simply because they want to bring the Prisoner's file up to date. The reason behind the Prisoner's resignation being the one piece of missing information!
Be seeing you
