"Energise." "Coadjutor engagement." " What happened?" " l took a flop." " Onto what?" " l don't know." "Some kind of yellow ore." " Magnetic." "Decontaminate that uniform." " Yes, sir." "That acted like a burn-out." "'Captain Kirk, ready to beam up.'" "Just one moment, Captain." "That checks out OK now." "You'd better get a synchronic meter so we can double-check." "All right, Captain." "Locked onto you." " Are you all right?" " Just a little dizzy." " Let me give you a hand." " l can't get through there." "Don't leave the transporter room unattended."

"You picked a good day, Fisher." "Business has been lousy." "Did you take a fall on purpose to get a vacation?" "Saurian brandy." "Back to duty status." "I have no sympathy for clumsiness." "No, sir." "The hand's much better, sir." " What can I do for you?" " l said, give me the brandy!" " (Knock on door)" " Yep." "It's Mr Spock." "Come in." "Yes, Mr Spock." "What is it?" " ls there something I can do for you?" " Like what?" "Well, Dr McCoy seemed to think that I should check on you." "That's nice." "Come on, Spock. I know that look." "What is it?" "Well, our good doctor said that you were acting like...a wild man." " Demanded brandy." " Our good doctor's been putting you on." "In that case, if you'll excuse the intrusion, I'll get back to my work." "I'll tell him you were properly annoyed." "Captain." " What is it?" " Transporter breakdown." "Continue circuit testing." "We beamed up this animal, and look for yourself in here." "A few seconds after they sent this one up through the transporter, that duplicate appeared." "Except it's not a duplicate." "It's an opposite." "Two of the same animal, but different." "One gentle - this." "One mean and fierce - that." "A savage, ferocious opposite." "Captain, we don't dare send Mr Sulu and the landing party up." "If this should happen to a man..." "Oh, my..." "Captain, you startled me." "is there something that you..." " Can I help you?"

"But we don't dare bring up the landing party." "They might be duplicated." " How long will it take to find the trouble?" " Can't say, sir." "We can't leave those men down there." "It's getting dark." "They'll die." "The temperature of that planet goes down to 120 below zero at night." " We're doing everything we can, sir." " Yes, I know, Scotty." " About your double, Captain..." " Yes." "Yes." "We'll have to find him." "Organise search parties." "We can't take a chance on killing it." "We have no way of knowing what would happen to you." "That's right." "We don't know." "But the men have to be armed." "The men are to be armed with their phasers locked, I repeat, locked on setting number 1."

"Tell them..." "The search parties, Captain." "I'll make an announcement to the entire crew." "Tell them what happened." "It's a good crew, they deserve to know." "Captain, no disrespect intended, but you must realise you can't tell the crew." "You're the captain." "You have no right to be vulnerable in the eyes of the crew." "You can't afford to be less than perfect." "If you do, they lose faith and you lose command." "Yes, I do know that, Mr Spock." "What I don't know is why I forgot that just now."

"You need me." "I need you." "I don't need you." "He'll be regaining consciousness soon. I don't think I dare give him a tranquilliser." " l think we'd better bind him." " Yes..." "Yes, all right." "What's the matter with me?" "Judging from my observations, you're rapidly losing the power of decision." " Do you have a point?" " Yes, always, Doctor." "We have an unusual opportunity to appraise the human mind, or to examine, in Earth terms, the roles of good and evil in a man." "His negative side, which you call hostility, lust, violence." "And his positive side, which Earth people express as compassion, love, tenderness." "It's the captain's guts you're analysing." "Are you aware of that?" "Yes." "And what is it that makes one man an exceptional leader?" "Indications are that his negative side makes him strong." "That his evil side, properly controlled and disciplined, is vital to his strength." "Your negative side removed from you, the power of command begins to elude you." "What is your point?" "If your command continues to weaken, you'll be unable to function as captain." "You must be prepared for that." "You have your intellect." "You can fight with that." "For how long?"

"Part of what he is makes you the man you are." "God forbid I should have to agree with Spock but he was right." "Without the negative side, you wouldn't be the captain." "You couldn't be." "Your strength of command lies mostly in him." " What do I have?" " You have goodness." "Not enough. I have a ship to command." "The intelligence, the logic." "It appears your half has most of that."

" lt couldn't understand." "You can." "You have intelligence controlling your fear." "Get the transporter room ready." "If." "Maybe." "All guesswork, just theory." "Let me do an autopsy and let Spock check out the transporter circuits again." "That sounds reasonable." "We should double-check everything." " Aren't you forgetting something?"

"(Man) 'Status report, green.'" " All sections report ready, sir." " Good." "Thank you, Mr Spock, from both of us." "Shall I pass that onto the crew, sir?" "The impostor is back where he belongs." "Let's forget him." "Captain, the impostor told me what happened, who he really was." "And I'd just like to say that..." " Well, sir, what I'd like to say is..." " Thank you, Yeoman."
