Sarek: Klingon justice is a unique point of view, Mr. President. Genesis was perfectly named-- the creation of life, not death. The Klingons shed the first blood while attempting to possess its secrets.
Klingon Ambassador: Vulcans are well-known as the intellectual puppets of this Federation.
Sarek: Your vessel did destroy U.S.S. Grissom. Your men did kill Kirk's son. Do you deny these events?
Klingon Ambassador: [proudly] We deny nothing. We have the right to preserve our race.
Sarek: You have the right to commit murder?
[Discussing the time warp maneuver]
Spock: I've had to program some of the variables from memory.
James T. Kirk: What are some of the variables?
Spock: Availability of fuel components, mass of a vessel through a time continuum, and probable location of humpback whales, in this case, the Pacific Basin.
Leonard McCoy: "Angels and ministers of grace, defend us."
Spock: Hamlet, act I, scene IV.
James T. Kirk: No doubt about your memory, Spock.
Spock: Admiral, may I ask you a question?
James T. Kirk: Spock, don't call me Admiral. You used to call me Jim. Don't you remember "Jim"? What's your question?
Spock: Your use of language has altered since our arrival. It is currently laced with, shall I say, more colorful metaphors-- "Double dumb-ass on you" and so forth.
James T. Kirk: You mean the profanity?
James T. Kirk: That's simply the way they talk here. Nobody pays any attention to you unless you swear every other word. You'll find it in all the literature of the period.
Spock: For example?
James T. Kirk: [thinks] Oh, the complete works of Jacqueline Susann, the novels of Harold Robbins....
Spock: Ah... The giants.
Pavel Chekov: Admiral, we have found the nuclear wessel.
James T. Kirk: Well done, team two.
Pavel Chekov: And, Admiral... it is the Enterprise.
[Kirk and Spock look at each other]
James T. Kirk: Understood. What's your plan?
Pavel Chekov: We will beam in tonight, collect the photons, and beam out. No one will ever know we were there.
James T. Kirk: Understood and approved. Keep me informed. Kirk out.
Federation President: As you wish. The charges and specifications are - conspiracy, assault on Federation officers, theft of Federation property, namely the starship Enterprise; sabotage of the USS Excelsior, willful destruction of Federation property, specifically the aforementioned USS Enterprise, and finally, disobeying direct orders of the Starfleet commander. Admiral Kirk, how do you plead?
Kirk:On behalf of all of us Mr. President, I am authorized to plead guilty.
Federation President: So entered. Because of certain mitigating circumstances, all charges but one are summarily dismissed. The remaining charge, disobeying orders of a superior officer, is directed solely at Admiral Kirk. I'm sure the admiral will recognize the necessity of keeping discipline in any chain of command?
Kirk: I do, sir.
Federation President: James T. Kirk, it is the judgment of this council that you be reduced in rank to captain. And that as a consequence of your new rank, you be given the duties for which you have demonstrated unswerving ability, the command of a starship. Captain Kirk, you and your crew have saved this planet from its own short-sightedness and we are forever in your debt.
Sarek: I am returning to Vulcan within the hour, I wanted to take my leave of you.
Spock: It was most kind of you to make this effort.
Sarek: It was no effort. You are my son. Besides, I'm most impressed with your performance during this crisis.
Spock: Most kind.
Sarek: As I recall, I opposed your enlistment in Starfleet... It is possible that judgment was incorrect. Your associates are people of good character.
Spock: They are my friends.
Sarek: Yes, of course. Do you have a message for your mother?
Spock: Yes, tell her...I feel fine. Live long and prosper, Father.
Sarek: Live long and prosper, my son.
[The crew is pondering what their ship will be.]
Leonard McCoy: The bureaucratic mentality is the only constant in the universe. We'll get a freighter.
Hikaru Sulu: With all respect, Doctor, I'm counting on Excelsior.
Montgomery Scott: Excelsior? Why in God's name would you want that bucket of bolts?
James T. Kirk: A ship is a ship.
Montgomery Scott: Whatever you say, sir. Thy will be done.
