- The Complainer Is Always Wrong: The belief of the Village Council and the villagers in general. Thinking for himself, being sarcastic, and not bowing to the Council's every whim is enough to get Number Six labeled antisocial and "Unmutual".
- Hoist by His Own Petard: A double helping.
- When Number Six realizes that Number Eighty-six has drugged his tea, he switches the teacups while her back is turned, resulting in Eighty-six drugging herself.
- Number Two warns that even he can't control the Village Council, as he leaves Number Six to their mercies. With help from the hypnotized Number Eighty-six, Number Six eventually turns the Council against Number Two. The episode ends with Two, now declared Unmutual, fleeing the Village on foot.
- Intoxication Ensues: Number Eighty-six unknowingly drinks the tea that she drugged herself. She gets loopy and absent-minded, and at one point she declares she's "higher than Number Two". While she's like this, Number Six hypnotizes her into being an accomplice in his plot against Number Two.
- Loners Are Freaks: Also the belief of the Village Council and the villagers in general. The episode opens with some thugs antagonizing Number Six—because he has the audacity to exercise alone in the woods, rather than in the communal gym.
- Placebo Effect: The punishment/treatment for being Unmutual is "Instant Social Conversion", allegedly an ultrasonic lobotomy. In reality, it's a sham—the doctors use lights, fake scars, and drugs to trick Number Six into thinking he's been lobotomized, in hopes that he'll act more compliant, as if he really were lobotomized.
- Silent Treatment: When Number Six is declared Unmutual, the Village initially punishes him by ostracising him. No one in the Village will speak to him, and when he sits down at a patio table, everyone else on the patio immediately leaves.
