Mr. Spock
- Captain James T. Kirk: We're a most promising species, Mister Spock, as predators go. Did you know that?
- Mr. Spock: I've frequently had my doubts.
- Captain James T. Kirk: I don't. Not anymore. And, maybe in a thousand years or so, we'll be able to prove it.
- [last lines]
- Mr. Spock: A thousand years, Captain?
- Captain James T. Kirk: Well, that gives us a little time.
- Mr. Spock: We're being held in place, Captain, apparently from that solar system.
- Captain James T. Kirk: This far out? That's impossible.
- Mr. Spock: We are being held.
- Mr. Spock: You mean to destroy the alien ship, Captain?
- Captain James T. Kirk: Of course.
- Mr. Spock: I thought perhaps the hot pursuit alone might be sufficient. Destruction may be unnecessary.
- Captain James T. Kirk: Colony Cestus III has been obliterated, Mr. Spock.
- Mr. Spock: The destruction of the alien vessel will not help that colony, Jim.
- Mr. Spock: A sustained warp 7 speed will be dangerous, Captain.
- Captain James T. Kirk: Thank you, Mr. Spock. I mean to catch them.
- Scott: We'll either catch them or we'll blow up, Captain. They may be faster than we are.
- Captain James T. Kirk: They'll have to prove it.
