Quotes Edit


  • James T. Kirk: Readout, Mister Chekov?
  • Pavel Chekov: No structures, Captain. No mechanized objects that I can read. No surface consumption, no generation of energy. Atmosphere is perfectly all right, of course. Temperature, a high maximum of 40. Livable.
  • James T. Kirk: You have a thick skin.


  • James T. Kirk: Have the transporter room standing by. I'm taking a landing party down to planet six.



  • Spock: While I might trust the doctor to remove a splinter or lance a boil, I do not believe he has the knowledge to restore a brain.
  • Leonard McCoy: Thank you.


  • James T. Kirk: How do you feel, Spock?
  • Spock: On the whole Captain, I believe I'm quite fit. It's fascinating! A remarkable example of a retrograde civilization at the peak, advanced beyond any of our capabilities and now operating at this primitive level which you saw. And it all began thousands of years ago when a glacial age reoccurred. You see, this underground complex was developed for the women. Men remained above. And male/female schism took place. A fascinating cultural development of a kind...
  • Leonard McCoy: I knew it was wrong, I shouldn't have done it!
  • James T. Kirk: What's that?
  • Leonard McCoy: I should have never reconnected his mouth!
  • James T. Kirk: Well, we took the risk, Doctor.


  • Kara: How will we live?
  • Spock: You'll learn to build houses to keep warm. You'll work. Humans have survived under worse conditions. It's a matter of evolution. Give it time.


  • Leonard McCoy: I'll never live this down... this Vulcan telling me how to operate.
