These Andorians were played by unknown actors. It is unclear if these technicians were meant to be one or two individuals, as both were located near the other, but never together. In the outward shot, the first technician appears on his back, slumped over the console, while the inward shot shows the second technician lying on the floor against the console, opposite of his previous position.
This female Human technician was the only survivor, albeit briefly, discovered by the USS Enterprise. When encountered, she was unable to speak, and merely gave off a mysterious croaking sound, similar to what had been previously heard by Mira Romaine following her encounter with the Zetarians.
