KIRK: Bones.
(Later.)
KIRK: Yeoman, record this for Starfleet Command.
ZAHRA: Ready, sir.
KIRK: The alien creatures on Deneva have been destroyed
ZAHRA: Captain, look. Mister Spock.
(Spock walks onto the Bridge, followed by McCoy.)
KIRK: Spock. You can see.
MCCOY: The blindness was temporary, Jim. There's something about his optical nerves which aren't the same as a human's.
SPOCK: An hereditary trait, Captain. The brightness of the Vulcan sun has caused the development of an inner eyelid, which acts as a shield against high-intensity light. Totally instinctive, Doctor. We tend to ignore it, as you ignore your own appendix.
KIRK: Mister Spock. Regaining eyesight would be an emotional experience for most. You, I presume, felt nothing?
SPOCK: Quite the contrary, Captain. I had a very strong reaction. My first sight was the face of Doctor McCoy bending over me.
MCCOY: 'Tis a pity your brief blindness did not increase your appreciation for beauty, Mister Spock.
KIRK: If you gentlemen are finished, would you mind laying in a course for Starbase Ten, Mister Spock?
SPOCK: My pleasure, Captain.
MCCOY: Unusual eye arrangement. I might've known he'd turn up with something like that.
KIRK: What's that, Doctor?
MCCOY: I said, please don't tell Spock I said he was the best first officer in the fleet.
SPOCK: Why, thank you, Doctor McCoy.
KIRK: You've been so concerned about his Vulcan eyes, Doctor, you forgot about his Vulcan ears. Ahead warp factor one, Mister Sulu.
SULU: Warp factor one, sir.
