The wife becomes a major threat to the Enterprise crew when it appears that she is responsible for the death of several crewmen who died after the removal of all salt in their body. The lone male survivor is unconcerned and hostile toward the crew's plight, and resists their attempt to evacuate him from the planet.

James Doohan doesn't appear, but they use a dubbed line of dialogue from another episode, played over the communicator, when Kirk beams up to the ship.
Kirk: Shall we pick some flowers, Doctor? When a man visits an old girlfriend... she usually expects something like that.
McCoy: Is that how you get girls to like you--by bribing them?
Kirk: Something wrong, Darnell?
Darnell: Excuse me, sir. Ma'am, if I didn't know better... I'd swear I knew you on Wrigley's Pleasure Planet. You're exactly like a girl...
McCoy: Less mouth, Darnell!
Kirk: How your lost love affects your vision is not my concern, Doctor! I've lost a man! I want to know what killed him!
Uhura: Starship base requesting explanation of our delay, sir. Space Commander Dominguez says we have supplies he urgently needs.
Kirk: Tell Jose he'll get his chili peppers soon. They're prime Mexican reds. I handpicked them. But he won't die without them.
Kirk: It's a mystery. I don't like mysteries! They give me a bellyache, and I've got a beauty right now.
Sulu: May the Great Bird of the Galaxy bless your planet.
Spock: Why risk your life for his?
Kirk: He's just trying to frighten us... and he's doing a pretty good job.
Crater: Earth history, remember? Like the passenger pigeon or the buffalo. Ooh! I feel strange.
Kirk: Just stunned. You'll be able to think in a minute.
Spock: The Earth buffalo. What about it?
Crater: Once there were millions of them; prairies black with them. One herd covered three whole states. When they moved -- like thunder.
Kirk: You bleed too much, Crater. You're too pure and noble. Are you saving the last of its kind... or has this become Crater's private heaven here? This thing becomes wife, lover, best friend, wise man, fool, idol, slave. It isn't bad to have everyone in the universe at your beck and call. You win all the arguments.
