In episode 2, 'The Chimes of Big Ben', Leo McKern make his debut as Number 2, and he is the best in my opinion. His humor and characterization make him the most memorable and he figures prominently in the last two episodes.
Number 6 must decide whether to trust Number 8, a new resident of the village. She seems quite sincere and gains his confidence. Together, they plan an escape. It appears successful initially, but old colleagues soon show Number 6 he is in for a long haul.
An exciting and wonderful episode.
PRISONER SCORE BOARD:
Village: 2
Number 6: 0
