Walter Koenig: Chekov
[Khan, about to put Ceti Eels in Terrell and Chekov's ears]
Khan : You see, their young enter through the ears and wrap themselves around the cerebral cortex. This has the effect of rendering the victim extremely susceptible to suggestion. Later, as they grow, follows madness and death.
Chekov : Khan, listen to me...
Khan : These are pets, of course. Not quite domesticated.
Khan : Captain, Captain, Captain... save your strength. These people have sworn to live and die at my command two hundred years before you were born. Do you mean he never told you the tale? To amuse your Captain, no? Never told you how the Enterprise picked up the Botany Bay, lost in space from the year 1996 with myself and the ship's company in cryogenic freeze?
Capt. Terrell : I never even met Admiral Kirk.
Khan : 'Admiral?' 'Admiral!' 'Admiral'... Never told you how 'Admiral' Kirk sent seventy of us into exile in this barren sandheap with only the contents of these cargo bays to sustain us?
Chekov : You lie! On Ceti Alpha Five there was life! A fair chance...
Khan : [shouts] THIS IS CETI ALPHA FIVE! Ceti Alpha Six exploded six months after we were left here. The shock shifted the orbit of this planet and everything was laid waste. 'Admiral' Kirk never bothered to check on our progress. It was only the fact of my genetically-engineered intellect that allowed us to survive. On Earth, two hundred years ago, I was a prince with power over millions...
Chekov : Captain Kirk was your host. You repaid his hospitality by trying to steal his ship and murder him!
Chekov : [to Khan] Captain Kirk was your host. You repaid his hospitality by trying to steal his ship and murder him!
Chekov : Oh, sir, it was Khan! We picked him up on Ceti Alpha Five... He put... creatures... in our bodies... to control our minds. He made us... say lies... do things. He thought he controlled us, but he did not. The Captain was strong.
