Spock: Frankly, I was rather dismayed by your use of the term "half-breed", captain. You must admit it is an unsophisticated expression.

Strong plot and with a shocking ending
2 September 2007 | by fabian5See all my reviews

This is an early Star Trek season one episode made when Captain Kirk, Spock, Uhura, Scotty, Sulu and Nurse Chapel were members of the standard Star Trek crew that we all recognize today. Basically, Nurse Chapel--Dr. Roger Korby's old flame--together with Captain Kirk beam down to an isolated planet for what they imagine is a friendly get together with the doctor. Unfortunately...for Kirk, Dr. Korby has other ideas and forces Kirk to make a clone of himself in order to seize control of the Enterprise. This is a memorable episode with a compelling and powerful ending when you discover who Dr. Korby really is. Its a remarkable show when you consider that Sulu and Scotty were did not appear in this episode and has to be considered a Star Trek classic.

The episode does indeed have an extremely well written script and several emotional scenes such as when Nurse Chapel get a kiss from Uhura before beaming down to see her long-lost fiancée and Dr. Korby's haunting words to Chapel when she discovers Korby's true identity.
