Romulan Commander
- Romulan Commander: We were not aware of Vulcans aboard the Enterprise.
- Spock: Starfleet is not in the habit of informing Romulans of its ship's personnel.
- Romulan Commander: It is unworthy of a Vulcan to resort to subterfuge.
- Spock: You're being clever, Commander. That is unworthy of a Romulan.
- Romulan Commander: [to Spock] If you'll give me a moment. The soldier will transform herself... into a woman.
- Romulan Commander: Romulan women are not like Vulcan females. We're not dedicated to... pure logic, and the sterility of non-emotion. Our people are warriors. Often savage. But we are also many other pleasant things.
- Captain James T. Kirk: What earns Spock your special interest?
- Romulan Commander: He is a Vulcan. Our forebears had the same roots and origins. Something you wouldn't understand, Captain. We can appreciate the Vulcans, our distant brothers.
- Romulan Commander: It was your choice.
- Spock: It was the only choice possible. You would not respect any other.
- Spock: It is regrettable that you were made an unwilling passenger. It was not intentional. All the Federation wanted was the cloaking device.
- Romulan Commander: The Federation. And what did you want?
- Spock: It was my only interest when I boarded your vessel.
- Romulan Commander: And that's exactly all you came away with.
- Spock: You underestimate yourself, Commander.
- Romulan Commander: I neglected to mention. I'll expect you for dinner. We have much to discuss.
- Spock: Indeed.
- Romulan Commander: Allow me to... to rephrase. Will you join me for dinner?
- Spock: I am honored, Commander. Are the guards also invited?
- Romulan Commander: There's no force that I can use on a Vulcan that will make him speak. That is a fact. But there are Romulan methods completely effective against Humans, and Human weaknesses.
- Spock: You would not resort to them, Commander. They would prove ineffective against the Captain.
- Romulan Commander: Then they will leave him dead. Or what might be worse than dead.
- [the Romulan commander has accused Kirk of espionage]
- Captain James T. Kirk: We were not spying, Commander.
- Romulan Commander: Your language has always been most difficult for me, Captain. Perhaps you have another word for it.
- Captain James T. Kirk: Commander, you'll forgive me if I put up a fight.
- Romulan Commander: Of course. It's expected.
- [Spock has deceived the Romulan commander to help steal the Romulans' cloaking device]
- Romulan Commander: You must be mad.
- Spock: I assure you, I am quite sane.
- Romulan Commander: Why would you do this to me? What are you that you could do this?
- Spock: First Officer of the Enterprise.
- [the Romulan commander realizes that Spock has betrayed her and slaps him]
- Spock: [dispassionately] What is your present form of execution?
- Romulan Commander: You are a superior being. Why do you not command?
- Spock: I do not desire a ship of my own.
- Romulan Commander: Or is it that no one has offered you, a Vulcan, that opportunity?
- Spock: Such opportunities are extremely rare.
- Romulan Commander: For someone with your capabilities and accomplishments, opportunities are made. And will be. I will see to that, if you'll stop looking on the Federation as the whole universe. It is not, you know.
- Spock: That thought has occasionally crossed my mind.
- Captain James T. Kirk: [When being questioned about the cloaking device] We've been over that already.
- Romulan Commander: IT HAS NOT YET BEGUN!
