Mr. Spock
- Capt. Kirk: [of Uhura] What d'you do to her?
- Nomad: That unit is defective. Its thinking is chaotic. Absorbing it unsettled me.
- Spock: That "unit" is a woman.
- Nomad: A mass of conflicting impulses.
- Spock: My congratulations, Captain - a dazzling display of logic.
- Capt. Kirk: You didn't think I had it in me, did you, Spock?
- Spock: [deadpan] No, sir.
- Spock: [Places hands on Nomad and conducts mild meld] I am Nomad. I am performing my function. Deep, emptiness. It approaches, collision, damage, blackness. I am the other. I am Tan Ru. Tan Ru. Nomad. Tan Ru. Error. Flaw. Imperfection. Must sterilize. Rebirth. We are complete. Much power. Gan Ta Nu Ika. Tan Ru. The creator instructs, search out, identify, sterilize imperfections. We are Nomad. We are Nomad. We are complete. We are instructed. Our purpose is clear. Sterilize imperfections. Sterilize imperfections. Nomad! Sterilize! Sterilize! Nomad! Sterilize!
- Capt. Kirk: Spock!
- Spock: Nomad! Sterilize!
- Capt. Kirk: Spock!
- Capt. Kirk: Nomad, you're in contact with the unit Spock! Stop! Stop!
- Nomad: Acknowledged.
- Capt. Kirk: [of Nomad's demise] It's not easy to lose a bright and promising son.
- Spock: Sir?
- Capt. Kirk: Well, it thought I was its mother, didn't it? D'you think I am completely without feelings, Mr. Spock? You saw what it did to Scotty. What a doctor it would have made.
- [a beat]
- Capt. Kirk: My son, the doctor.
- Capt. Kirk: [fists his own heart] Kind of gets you right there, doesn't it?
- Spock: [trying to fathom an explanation for the complete loss of life to a billion inhabitants virtually overnight] Sensor readings would've revealed the presence of any disease organisms; they do not. In addition, we received a routine report from this system only a week ago - even the Cymbeline Blood Burn does not act that swiftly.
- Spock: [Places hands on Nomad and conducts mind meld] I am Nomad. I am performing my function. Deep, emptiness. It approaches, collision, damage, blackness. I am the other. I am Tan Ru. Tan Ru.
