Spock: (voiceover) Enterprise log. First officer Spock — acting Captain. I must now use an ancient Vulcan technique to probe into Van Gelder's tortured mind.
McCoy: Spock, if there's the slightest possibility it might help...
Spock: I've never used it on a human, Doctor.
McCoy: If there's any way we can look into this man's mind to see if what he's seeing is real or delusion...
Spock: It's a hidden, personal thing to the Vulcan people, part of our private lives.
McCoy: Now look, Spock, Jim Kirk could be in real trouble. Will it work or not?
Spock: (to Gelder) It could be dangerous. Do you understand? It requires I make pressure changes in your nerves, your blood vessels.
Spock: This will not affect you, Doctor McCoy, only the person I touch. It is not hypnosis.
