The Enterprise orbits a planet, Lactra 7, to find a missing six-member science crew. The Ariel is deserted and the last log is from Lt. Commander Markel, who was unable to contact the three members who went down in the first landing party. Markel and the remaining two crew members went down to find them. Kirk is less than thrilled that Markel violated standing orders and sent everyone down. Spock reports that Lactra 7 is a Class M planet with no previous information. The crew went down five weeks ago, and Spock is unable to speculate further on the planet's inhabitants without a complete scan. Kirk orders a landing party down to the same coordinates that Markel used. McCoy objects that it's a risk but Kirk insists...Read the full recap
Kirk: The captain of a ship, no matter his rank, must follow the book.
Spock: A capability, I'm afraid, out of the reach of most humans.
McCoy: You Vulcans are the most impossible, unimaginative...
Kirk: Bones, that's not helping the situation.
Kirk: According to their log they beamed down six weeks ago.
Spock: Five weeks, three days, two hours, and four minutes to be exact, Captain.
Kirk: Careless of me, Mister Spock.
McCoy: Strange you didn't get a voice reply.
Spock: There could be many reasons why we did not.
McCoy: Well, never mind counting them.
McCoy: Thanks. The--the air was running out under there.
Kirk: Were you hurt?
McCoy: No, just surprised. It isn't every day a dinosaur falls on you.
McCoy: My shoes are full of sand.
Spock: Doctor, your lack of scientific interest is amazing.
McCoy: I'll be happy to discuss that with you, Mr. Spock, next time you drop into my medical lab.
Kirk: This seems like random choice.
Spock: Unless, of course, the random choice is the pattern.
McCoy: Spock, do you ever say anything straight out?
Spock: I thought I just did, Doctor.
Kirk: A forcefield. It seems harmless enough.
McCoy: So do the bars of a jail unless you're on the inside.
Kirk: You seem to be getting a response.
Spock: My impression is that... they're laughing at me.
Lieutenant Commander Markel: So far, Mr. Spock, we haven't found anything funny in this.
Spock: Animals in a zoo rarely do.
Kirk: What else do they know about us?
Spock: We are considered simplistic, but in the process of evolving into a higher order.
McCoy: Even Vulcans?
Spock: Yes, even Vulcans.
