The Enterprise transports the Medusan Ambassador Kollos; his telepathic interpreter, Dr Miranda Jones; and Engineer Laurence Marvick. Only Vulcans and those trained in Vulcan self-control can handle the horrible sight of a Medusan (and then only with eye protection). Attempting to kill Kollos, Marvick (jealous of Miranda's interest in Kollos) goes insane at the sight of the Mudasan ambassador. Before dying Marvick, one of the designers of the Enterprise, takes the ship outside the galaxy where it is hopelessly lost. Once it is discovered that Miranda is blind (she had fooled them with a complicated neural sensor in her dress) and cannot guide the Enterprise, Spock mind-melds with the navigationally proficient ambassador who quickly gets the Enterprise back in known galactic space. However, while severing the mind-meld, he forgets the visor, sees Kollos, and goes insane. Because of her jealousy of Spock's relationship with Kollos, Miranda hesitates to give help, but with Kirk's urging ... Written by JW Kearse

[first lines]
Captain James T. Kirk: Captain's log, stardate 5630.7. We have been assigned to convey the Medusans' ambassador to the Federation back to their home planet. While the thoughts of the Medusans are the most sublime in the galaxy, their physical appearance is exactly the opposite. They have evolved into a race of beings who are formless, so utterly hideous that the sight of a Medusan brings total madness to any human who sees one.

It Does Strain Our Patience
4 May 2014 | by (United States) – See all my reviews

The unknown is sometimes presented as much more frightening than the known. Here the horror of horrors is contained in a receptacle the looks like a toolbox I made in metal shop. This is a Medusan whose visage is so bad that it drives anyone who views it, mad. Aboard the ship is his chaperon, Diana Muldaur, who is blind, hence in no danger from his look. Also with her is a man who was an engineer instrumental in the design of the Enterprise. He is jealous of her fixation on the Medusan, not romantically but rather in her choosing this life over one with him. He decides to kill the Ambassador but in the process, looks upon it, causing him to go berserk and gain control of the ship, driving it to the edge of the galaxy. For some reason, Muldaur's character is unwilling to help in any way. Spock has the ability, using his mind meld, to take on, in human form, the Medusan. She refuses (I don't know why, other than Spock's ability to telepathically connect with other species). Even when Spock makes a near fatal mistake (forgetting his visor), she categorically refuses to assist. Ultimately, this is a really dull episode, plodding along at about a mile per hour. Motivations for actions are left in the ditch and show another slide into mediocrity for the third season.
