- Capt. Kirk: You're not going to admit that for the first time in your life you committed a purely human, emotional act?
- Spock: No, sir.
- Capt. Kirk: Mr. Spock, you're a stubborn man.
- Spock: Yes, sir.
- Dr. McCoy: Well, Mr. Spock, they didn't stay frightened very long, did they?
- Spock: Most illogical reaction. We demonstrated our superior weapons. They should have fled.
- Dr. McCoy: You mean they should have respected us?
- Spock: Of course.
- Dr. McCoy: Mr. Spock, respect is a rational process. Did it ever occur to you they might react emotionally, with anger?
- Spock: Doctor, I'm not responsible for their unpredictability.
- Spock: Strange. Step by step I have made the the correct and logical decisions, and yet two men have died.
- Capt. Kirk: Look, these people are my friends and my shipmates. I intend to continue this ship's search for them until the last possible moment.
- Commissioner Ferris: Very well, Captain. But not one second beyond that moment. Is that clear?
