When Green (Nancy) confronts Yeoman Rand at the elevator, Rand takes two bites from one of the celery-like pieces on the food plate. Moments later in the biology lab, after she's placed the plate in front of Sulu, Green stares down at it and in the close up the same celery pieces appear whole and not partially eaten. See more »


[first lines]
Captain James T. Kirk: Captain's log, stardate 1513.1. Our position, orbiting planet M-113. On board the Enterprise, Mr. Spock, temporarily in command. On the planet, the ruins of an ancient and long-dead civilization. Ship's surgeon McCoy and myself are now beaming down to the planet's surface. Our mission: routine medical examination of archeologist Robert Crater and his wife Nancy. Routine but for the fact that Nancy Crater is that one woman in Dr. McCoy's past.

Dr. McCoy's Old Flame
20 December 2016 | by Rainey-DawnSee all my reviews

Nancy Crater and Dr. McCoy at one time was very close... it's been years since they've seen each other. Naturally Bones was excited to find out he'll see Nancy again while on the planet M-113. Nancy has gotten married to Professor Robert Crater, a man that knows all about Nancy. Nancy is not quite her old self, trying to harm the Starship Crew for Salt.

Off to a great start with the first season, first episode of ST-TOS. It is taken very much seriously - nothing cutesy or funny about it. Like all Star Trek TOS - you'll either like the Captain and Crew or you simply won't.

Oddly, this episode looks and feels like a later episode... one that you know the characters better rather than the very first episode aired for TV audiences in 1966.
