During his opening election speech of 'Free For All,' No.6 said that he intended to discover who are the prisoners and who are the warders. In 'checkmate' No.6 was told by No.14 how to distinguish between the blacks and the whites, you soon find out who is for or against you. It's the same as it is in life, you judge by attitudes. So No.6 did find out who are the prisoners and who the warders, for what little good it did him!
I'll be seeing you
