"Cold Station 12" is the name of the 81st episode from the television series Star Trek: Enterprise. It is the fifth episode from the fourth season of the series, initially airing on November 5, 2004. The episode is the middle of a three-episode arc involving the "Augments," preceded by "Borderland" and followed by "The Augments."
The episode's title is the name of the medical facility run by Starfleet Medical and the Denobulans, where much of this episode's plot unfolds. The episode features the first on-screen appearance of Dr. Jeremy Lucas, a close friend of Dr. Phlox who had been mentioned in numerous previous episodes.
This is the location where the young Augments were raised and schooled by Dr. Soong. It is also where the Enterprise away team discovers a brother of the Augments named Udar. Analysis reveals that although Udar's DNA is similar to the other Augments, he has none of their enhanced abilities. Udar is nicknamed "Smike" by his Augment siblings after a handicapped character from the comic novel Nicholas Nickleby by Charles Dickens.
In this episode, we learn that after the devastating Eugenics Wars (in which up to 35 million were killed), Earth's governments could not decide on the fate of the genetically enhanced embryos, so they were placed in cold storage for the time being.
We also find out that while Dr. Soong had stolen 19 embryos from Cold Station 12, some 1800 frozen embryos, leftover from the Eugenics Wars, are still stored at C-12.
