Episode complete credited cast:


The Enterprise shuttlecraft, carrying Kirk, Spock, Dr. McCoy and critically ill Federation Ambassador Nancy Hedford, encounters a mysterious energy cloud which pulls them down to planet Gamma Canaris N. There they meet a castaway, a young man who purports to be Zefram Cochrane, inventor of the Warp Drive over 100 years ago. In history he had lived to be 80 years of age before disappearing somewhere in space. Apparently the same energy cloud which brought the shuttlecraft to the planet also found and rejuvenated Cochrane, making him effectively immortal. Unless Kirk can get themselves released soon, the ambassador, without vital medical treatment, will die. Written by Clive Wilson

Did You Know?


When Kirk asks Cochran for his first name, he replies "ZEFRAM". Kirk then asks him if he is from ALPHA CETI and the inventor of warp drive. Cochran then confirms he is. Yet in the movie "Star Trek:First Contact", Zefram Cochran is from Earth. See more »


Just after the first time that Kirk uses the universal translator to speak with The Companion, Kirk, Spock, and McCoy turn to walk into Cochrane's shelter, which they were standing less than 10 feet away from, while Cochrane is at least 50 yards away. When the shot switches to the interior, Kirk, Spock, and McCoy are seen coming through the entry door, immediately followed by Cochrane, even though Cochrane would have been 30-45 seconds away at normal walking speed.

Mr. Spock: This is a marvelous opportunity to add to our knowledge. Ask it about its nature, its history.
Captain James T. Kirk: Spock, this isn't a classroom. I'm trying to get us out of here.
Mr. Spock: A chance like this may never come again. It could tell us so much.
Captain James T. Kirk: This isn't the time.

Zefram, The Companion & Love
9 January 2017 | by (United States) – See all my reviews

Season 2, episode 9. Kirk, Spock and McCoy are on the way back to the Enterprise in a shuttle craft with the very ill Federation diplomat Nancy Hedford when the craft is kidnapped by an energy cloud and taken to the planet of Gamma Canaris N. There they find a very strange man Zefram Cochrane who is friendly. The group soon learn that Cochrane is the same Zefram Cochrane that invented Warp Drive some 150 years ago. Cochrane's body was never found but would be dead 150 years later. It is the Companion, an energy source, that has reversed Cochrane's aging and keeps him young and alive. The Companion refuses to let Kirk and the group leave for it fears that Cochrane will die of loneliness and wants Kirk and the group to stay for Cochrane's sake. Now Kirk, Spock and McCoy must find a way out of there.

I am NOT fond of Donahue's portrayal of Nancy Hedford because she sounded too demanding to be a diplomat... her tone of voice in the role was very wrong for the role of a diplomat (dying or not). Otherwise it's a pretty good episode - I love the idea behind it.
