When the Enterprise attempts to penetrate a space barrier, it is damaged and creates a potentially worse problem. Two crew members, including Kirk's best friend, gain psionic powers that are growing at a geometric rate. That leaves Captain Kirk with the difficult choice of either marooning them or killing before they get so powerful that they lose their humanity and become truly dangerous.

Errors and Explanations - Nitpickers Guide for Classic TrekkersEdit

Plot OversightsEdit

  1. Confusion over who the title refers to. According to the trivia section of this episode's entry in the Internet Movie Database, the title is taken from the opening pre credits monologue, although it could be intended to link Mitchell and Dehner with the crew member from the Valiant.

Internet Movie DatabaseEdit

Character errorEdit

  1. When the Enterprise officers are in the boardroom discussing the increase in Gary's ESP abilities, Sulu uses the word "geometric" instead of "exponential". While both refer to growth rates of a mathematical function proportional to the function's current value, "geometric" refers to a function with discrete domain values; "exponential" refers to a continuous domain value. (Sulu's description of starting with a penny and doubling it daily is correctly geometric, but Mitchell's ESP was continually growing, so exponential would be more appropriate.) Perhaps Mitchell's abilities are doubling at this stage.
  2. Gary Mitchell makes Captain Kirk's "headstone" which reads: "James R. Kirk." In all other Star Trek references, his name is "James Tiberius Kirk". Even in his god-like state, Mitchell is capable of making mistakes

Crew or equipment visibleEdit

  1. Lee Kelso's wristwatch is visible under his uniform sleeve at 4 minutes 3 second. Possibly a good luck charm?

Incorrectly regarded as goofsEdit

  1. The events of this episode obviously occur significantly earlier than the bulk of the rest of the series. As such, the educational title of physicist that is given to Sulu is in line with subsequent appearances where he is later promoted to the positional title of, and referred to as a 'helmsman'.
  2. The events of this episode obviously occur significantly earlier than the bulk of the rest of the series. As such, both Sulu and Spock have time to change their occupation, and as such get promotions and change their respective uniform colors.
