Dr. McCoy: This is the first time in a week I've had time for a drop. Would you care for a drink, Mr. Spock?
Mr. Spock: My father's race was spared the dubious benefits of alcohol.
Dr. McCoy: Oh. Now I know why they were conquered. What are you worried about? Jim generally knows what he's doing.
Mr. Spock: It was illogical for him to bring those players aboard.
Dr. McCoy: Illogical? Did you get a look at that Juliet? That's a pretty exiting creature. Of course your, uh, personal chemistry would prevent you from seeing that. Did it ever occur to you that he simply might like the girl?
Mr. Spock: It occurred. I dismissed it.
Dr. McCoy: You would.
Dr. McCoy: In the long history of medicine, no doctor has ever caught the first few minutes of a play.
Captain James T. Kirk: You've got me backed into a corner. The men would never forgive me if I deprived them of your performance and your presence.
Dr. McCoy: What if you decide that he is Kodos? What then? Do you play God, carry his head through the corridors in triumph? That won't bring back the dead, Jim
Captain James T. Kirk: No. But they may rest easier.
Lenore Karidian: And this ship... All this power, surging and throbbing yet under control. Are you like that, Captain? All this power at your command, yet the decisions that you have to make...
Captain James T. Kirk: Come from a very human source.
Mr. Spock: You've got to pull him through.
Dr. McCoy: I'm not sure I can.
Mr. Spock: If he dies, the only one who'll able to identify Kodos is the captain, and he'll be the next target.
Anton Karidian: If you're so sure that I'm Kodos, why not kill me now? Let bloody vengeance take its final course! And see what difference it makes to this universe of yours.
Captain James T. Kirk: Those are beautiful words, well-acted. Change nothing.
Anton Karidian: I suppose not. They're merely tools, like this ship of yours.
Mr. Spock: Even in this corner of the galaxy, Captain, two plus two equals four. Almost certainly an attempt will be made to kill you. Why do you invite death?
Anton Karidian: I am an actor. I play many parts.
Captain James T. Kirk: You're an actor now. What were you twenty years ago?
Anton Karidian: Younger, Captain. Much younger.
Lenore Karidian: You are like your ship - powerful and not human. There is no mercy in you.
Captain James T. Kirk: If he is Kodos, then I've shown him more mercy than he deserves. If he isn't, then we'll let you off at Benecia, and no harm done.
Lenore Karidian: Captain Kirk, who are you to say no harm was done?
Captain James T. Kirk: Who do I have to be?
Captain James T. Kirk: The play is over. It's been over for twenty years
Anton Karidian: I was a soldier in a cause. There were things to be done, terrible things.
Captain James T. Kirk: Lt. Kevin Riley in communications - I wish to have him transferred down to the Engineering decks.
Mr. Spock: He came up from Engineering, Captain.
Captain James T. Kirk: Well, I'm sending him back.
Mr. Spock: Any explanation? He's a fine, young officer. He's bound to consider this transfer a disciplinary action.
Captain James T. Kirk: I don't wish to discuss it, Mr. Spock. Please follow my orders.
Anton Karidian: [reading] The revolution is successful, but survival depends on drastic measures. Your continued existence represents a threat to the well-being of society. Your lives means slow death to the more valued members of the colony. Therefore, I have no alternative but to sentence you to death. Your execution is so ordered. Signed, Kodos, governor of Tarsus IV.
Lenore Karidian: So, the captain of the Enterprise... Interesting.
Captain James T. Kirk: So, Lady Macbeth... Interesting. What's your next move?
Lenore Karidian: Has the machine changed them? Made them just people instead of women?
Captain James T. Kirk: Worlds may change, galaxies disintegrate, but a woman... always remains a woman.
Lenore Karidian: All this, and power too. Caesar of stars. Cleopatra... to worship him.
Larry Matson: [replying through intercom] Larry Matson here. Is that you, Riley? What's up?
Kevin Riley: Not me. I am down... In the engineering room.
Larry Matson: Maybe you've been a bad boy.
Kevin Riley: Maybe so. Whatever I've done, they're sure keeping it a secret from me.
Dr. Leighton: That man on the stage - I'm certain of it - that's Kodos the Executioner.
Enterprise Computer: Kodos the Executioner. Summary: Governor of Tarsis IV twenty Earth years ago. Invoked martial law. Slaughtered 50% of population Earth colony that planet. Burned body found when Earth forces arrived. No positive identification. Case closed.
Captain James T. Kirk: I had hoped to meet your father here tonight, personally.
Lenore Karidian: I'm sorry, Captain Kirk. He has a rigid rule about that. He never sees anyone personally, and he never attends parties.
Captain James T. Kirk: An actor turning away his admirers? Very unusual.
