Number 6 regressed to his childhood Number 2 takes Number 6 through his life in the hope that when he arrives at the point when the Prisoner resigns he’ll be more amicable towards giving the reason behind his resignation. ‘Once Upon A Time’ is a superb piece of stage acting, the one on one situation, but with the Butler on hand to help out as each part of Number 6’s life is played out. But its not the first time we have witnessed a one to one situation, ‘Hammer Into Anvil’ could be described as that. After all the main protagonists are Number 6 and Number 2, with Number 14 called upon to help out on occasion.
Originally ‘Once Upon A Time’ or to give the episode its working title of Degree Absolute,’ was not meant to have been a prequel to ‘Fall Out,’ but a stand alone episode. Had it remained so, there would have been no resuscitation of Number 2 as there is in ‘Fall Out,’ instead he would have remained dead at the end of the episode!
