We are all Pawns #5 - The Schizoid Man

Vera Wylde and Jessie Gender take up residence in the Village wherein can be found "The Prisoner." 

Episode 5, The Schizoid Man - The newly arrived #12 has been brought in to help break the stubborn #6 by perfectly mimicking him and causing a break in mental stability and identity. Except... #12 is absolutely certain that he IS #6. Jessie and I have a heck of a time trying to explain this one.
