No. 6 is taken to task for his “unmutualism” and ostracized by his fellow Villagers.
Obviously, this episode strikes a blow against conformity and encourages individuality, which is a common theme for the entire series. And again, No. 6 turns No. 2’s plot on himself and wins another point in his favor. But is this really a victory? The Villagers don’t change their opinion–they only accept No. 6 after he pretends to conform, then turn against No. 2.
