- Roberta Lincoln: [indicating Isis] Would you mind telling me who that is?
- Mister Seven: That, Miss Lincoln, is simply my cat.
- [last lines]
- Mister Seven: What else do your record tapes show?
- Captain James T. Kirk: I'm afraid we can't reveal everything we know, Mister Seven.
- Mr. Spock: Captain, we could say that Mister Seven and Miss Lincoln have some... interesting experiences in store for them.
- Captain James T. Kirk: Yes, I think we could say that. Two to beam up, Scotty.
- Mr. Spock: Live long and prosper, Mister Seven.
- Captain James T. Kirk: And the same to you, Miss Lincoln. Energize.
- [first lines]
- Captain James T. Kirk: Captain's log. Using the light speed breakaway factor, the Enterprise has moved back through time to the 20th century. We are now in extended orbit around Earth, using our ship's deflector shields to remain unobserved. Our mission - historical research. We are monitoring Earth communications to find out how our planet survived desperate problems in the year... 1968.
- Captain James T. Kirk: Captain's log, supplemental. Spock and I in custody. Even if we'd talk, they wouldn't believe us. We're powerless to stop Mr. Seven or prevent the launch, or even be certain if we should. I have never felt so helpless.
- Roberta Lincoln: Mister Seven, I want to believe you. I-I do. I mean, I know this world needs help. That's why some of my generation are... kind of crazy and rebels, you know. We wonder if we're gonna be alive when we're thirty.
- Captain James T. Kirk: [Kirk and Spock run into the back office as Roberta lets the cops in] Now, Scotty!
- First Policeman: What's going on here?
- [Kirk, Spock, and the two policemen beam aboard. Kirk and Spock run off the transporter]
- Captain James T. Kirk: Reverse and energize.
- First Policeman: [to his partner, confused] Charley...
- [the policemen beam back to the office]
- Scott: [on Kirk's open and activated communicator] Captain, can you read me? I was beaming up Mr. Seven and something yanked him away from me.
- Security Chief: [picks up communicator] Hello? Hello, come in.
- Mr. Spock: Here...
- Security Chief: [into communicator] Who are you?
- Mr. Spock: ...let me help you, Sergeant. It's operated from this dial here.
- [Spock nerve-pinches him]
- Roberta Lincoln: [to the green computer-interfaced cube] All right, don't answer. But you can tell him I quit. You can tell him I promise not to tell anybody anything. He's safe. And you're safe, my little green friend.
- [the cube flashes twice]
- Roberta Lincoln: Same to you.
- Beta 5 Computer: In response to nuclear warhead placed in sub-orbit by other major power, United States today launching sub-orbital platform with multi-warhead capacity. Purpose: to maintain balance of power.
- Mister Seven: That's the same kind of nonsense that almost destroyed planet Omicron IV.
- Roberta Lincoln: [frustrated] Okay. That does it. I quit!
- Mister Seven: Wait a minute, what're you...
- Roberta Lincoln: I'm quitting right now!
- Mister Seven: You're not acting, are you?
- Roberta Lincoln: [puts on her coat and grabs her purse] Acting? I'm leaving! Goodbye.
- [walks to the door. Gary locks it with his servo]
- Roberta Lincoln: Hey. Hey!
- Mister Seven: [activates cube on desk] Tie into computer.
- Beta 5 Computer: Computer on.
- Mister Seven: Scan unidentified female present.
- Beta 5 Computer: Roberta Lincoln, human. Profession: secretary.
- Roberta Lincoln: [nervously] Ha...
- Beta 5 Computer: Employed by 347 and 201. Description: age 20; five feet, seven inches; 120 pounds. Hair presently tinted honey-blonde. Although behavior appears erratic, possesses high I.Q.
- Roberta Lincoln: Heh!
- Beta 5 Computer: Birthmarks:...
- Roberta Lincoln: Hey.
- Beta 5 Computer: Small mole on left shoulder; somewhat larger star-shaped mark on her...
- Roberta Lincoln: [deactivates cube] Hey! Watch it! Okay, I'll bite. What is it?
- Mister Seven: [realizing he has given himself away] Miss Lincoln... Miss Lincoln, um... What kind of work did your employers say they were doing here?
- Roberta Lincoln: Research for a new encyclopedia?
- [Seven looks at her]
- Roberta Lincoln: No? No.
- Roberta Lincoln: Hold it, Mr. Seven. I'm telling you, you're through monkeying around with my country's rocket.
- Mister Seven: Roberta, you've gotta let me finish what I've started, or in six minutes World War III begins!
- Mr. Spock: Without facts, the decision cannot be made logically. You must rely on your human intuition.
- Mister Seven: Problem: Earth technology and science has progressed faster than political and social knowledge. Purpose of mission: to prevent earth's civilization from destroying itself before it can mature into a peaceful society.
