Did You Know?


This is the only TOS episode in which the three primary female crew members - Uhura, Chapel, and Rand - appeared together. The characters did not appear together again until Star Trek: The Motion Picture (1979). See more »


Towards the end, Kirk orders a hyperbolic course, and Lieutenant Brent, at the navigator's station, asks for a direction. But he turns to the right to face Spock's station (Spock is in engineering) when he asks it. Kirk is over Brent's left shoulder, but if Brent had turned that way to deliver his line, he'd have had his back to the camera. See more »


Dr. McCoy: Your pulse is two hundred and forty-two. Your blood pressure is practically non-existent. Assuming you call that green stuff in your veins blood...
Spock: The readings are perfectly normal for me, Doctor, thank you. And as for my anatomy being different from yours, I am delighted.

PSI 2000 Goes Out with a Bang
11 May 2017 | by Samuel-ShovelSee all my reviews

This is a great example of how to tie character development into the plot of your episode. The use of a bug to unearth the crew's inhibitions and self-doubt makes for a great episode and good way for the audience to find out more about these characters. Spock's struggle with emotion, Kirk's conflict between finding romantic love and maintaining Captain-like control, Sulu's... fencing hobby?

All of this further's the development of these characters and makes the audience identify with their plights. Mix this with a little bit of peril and you have yourself a solid episode.
