History Recap / StarTrekS3E17ThatWhichSurvives

* TravellinAtTheSpeedOfPlot: Even before Losira causes the Enterprise to overspeed, the ship is on course to cover nearly a thousand light years in half a day. It's lucky that the good ship ''[[Series/StarTrekVoyager Voyager]]'' couldn't match this performance, or she would have been back from the Delta Quadrant in barely five uneventful weeks.

* SciFiWritersHaveNoSenseOfScale: Even before Losira causes the Enterprise to overspeed, the ship is on course to cover nearly a thousand light years in half a day. It's lucky that the good ship ''[[Series/StarTrekVoyager Voyager]]'' couldn't match this performance, or she would have been back from the Delta Quadrant in barely five uneventful weeks.

* StrawVulcan: Spock is pretty terrible in this episode with a performance strongly comparable to his one in [[Recap/StarTrekS1E16TheGalileoSeven "The Galileo Seven"]].

* TheNeedsOfTheMany: Scotty tells Spock to jettison the pod he's in to save the rest of the ship. Uncharacteristically (especially for this episode), Spock refuses even after the countdown expires, and Scotty is forced to pull another wonder out of his sleeve.

* {{Flanderization}}: The writer really doesn't seem to get Spock -- something all the stranger given that the episode's story came from Creator/DCFontana, while the teleplay was written by John Meredyth Lucas, another experienced TOS writer and occasional director -- having him be mystified by the human crew's use of metaphors and tendency to round off their figures, when numerous other episodes show him to be perfectly fine with these things. In this regard, he actually comes off much closer to [[Series/StarTrekTheNextGeneration Data]]. On top of that he generally behaves like a {{Jerkass}}, constantly speaking down to the human crewmembers and chewing them out over minor things, as though his usual behavior toward [=McCoy=] had been turned up to eleven and directed at the entire crew.
** He does use what he hears later on when he remembers Scott spoke about the "feel" of the ship being wrong. He says he doesn't necessarily understand it, but takes it seriously enough to run a computer analysis to discover ''what'' is making Scott feel this way.

* BadassNormal: A redshirt saves the day by disabling the computer's defense mechanisms with his phaser.

* BigDamnHeroes: Kirk, [=McCoy=], and Sulu were trapped by the multiple Losiras, until Spock and a RedShirt arrive just in time to shoot the computer.

Soon after, there's an earthquake on the planet and the ''Enterprise'' has another of its famous shake ups where Uhura does her best not to do a PantyShot. It seems the planet and the starship have been mysteriously hurled several hundred light years away from each other. ([[TheSpock "990.7 light years. I wish you would be more precise."]]) However, the image of the same strange woman appears in both places, bringing a TouchOfDeath with her.

* RockPaperSwitch: When Kirk realizes that each Losira projection can only kill the one she was "sent" for he has his men move to protect each other. When the computer generates three projections, one for each of them, they desperately switch things up to delay the projections for a few moments, but Kirk realizes they're in big trouble.

* AbsenteeActor: Chekov doesn't appear in this episode, although Kirk mentions him.

There is a puzzling Class M planet that the ''Enterprise'' has come across. A planet of its absurdly young 1,000 years should not have vegetation and an atmosphere capable of sustaining life. (Shut up, Young Earthers!) Kirk beams down with Bones, Sulu and the [[RedShirt not long for this universe]] Lieutenant D'Amato. With a [[WackySoundEffect "Boing!"]] a woman wearing enough eyeshadow to make Tammy Faye Baker cringe pops up out of nowhere and kills the ensign who's beaming the party down--with a single touch. Losira, as we later learn she's called, doesn't quite count as GirlOfTheWeek since no one survives her touch long enough to make it with her.

* EnthrallingSiren: Deconstructed. Losira’s image was the only one available to the computer and the great majority of RedShirts [[MenAreTheExpendableGender are men]], [[IDidntMeanToTurnYouOn so the seduction aspect was accidental]].

* {{Flanderization}}: The writer really doesn't seem to get Spock -- something all the stranger given that the episode's story came from TOS legend D.C. Fontana, while the teleplay was written by John Meredyth Lucas, another experienced TOS writer and occasional director -- having him be mystified by the human crew's use of metaphors and tendency to round off their figures, when numerous other episodes show him to be perfectly fine with these things. In this regard, he actually comes off much closer to [[Series/StarTrekTheNextGeneration Data]]. On top of that he generally behaves like a {{Jerkass}}, constantly speaking down to the human crewmembers and chewing them out over minor things, as though his usual behavior toward [=McCoy=] had been turned UpToEleven and directed at the entire crew.

* CaptainObvious: When pondering who could be behind all these mysterious deaths, Kirk says "Someone did it." No! You think?
** This ''is'' Star Trek. A lot of mysterious deaths being caused by some''thing'' is a perfectly valid option.

!!Tropes for this episode include:

* TheNeedsOfTheMany: Scotty tells Spock to jettison him and a malfunctioning part to save the rest of the crew. Uncharacteristically, Spock refuses, and Scotty is forced to pull another wonder out of his sleeve.

* LetsSplitUpGang: Kirk suggests this when they find themselves stranded on the planet.

* RockPaperSwitch: A computer generated construct had the power to kill a specific human target by touch. When the Enterprise crew members facing it realized this, they interposed someone else between the opponent and its target, foiling the attack. Eventually the computer wised up and created a construct for each crew member, so the crew switched around until each was facing a construct meant for someone else.

* SciFiWritersHaveNoSenseOfScale: Even before Losira causes the Enterprise to overspeed, the ship is on course to cover nearly a thousand light years in half a day. It's lucky that the good ship ''[[Series/StarTrekVoyager Voyager]]'' couldn't match this performance, or she would have been back from the Delta Quadrant in barely five uneventful weeks. And you have to wonder what all the fuss was about when they were struggling to intercept the giant asteroid a few episodes ago in "[[Recap/StarTrekS3E3TheParadiseSyndrome The Paradise Syndrome]]". They should have been there in less time than it took Scotty to complain that the engines couldna take it!
** They had busted their warp drive in trying to deflect Super Asteroid, and apparantly impulse engines can only JUST match it's drift speed. :)

There is a puzzling Class M planet that the ''Enterprise'' has come across. A planet of its relatively young 1,000 years should not have vegetation and an atmosphere capable of sustaining life. (Shut up, Young Earthers!) Kirk beams down with Bones, Sulu and the [[RedShirt not long for this universe]] Lieutenant D'Amato. With a [[WackySoundEffect "Boing!"]] a woman wearing enough eyeshadow to make Tammy Faye Baker cringe pops up out of nowhere and kills the ensign who's beaming the party down--with a single touch. Losira, as we later learn she's called, doesn't quite count as GirlOfTheWeek since no one survives her touch long enough to make it with her.

* LogicBomb: Kirk forced a hologram to back off by making her consider the logic of killing to protect a dead world, and why she must kill if she knows it's wrong.

* MediaWatchDog: Lee Meriwether wears a crop-top and bell bottom pants—with a rectangular tab about four inches by five extending up from the waistband to conceal the forbidden sight of her navel. Will could show an entire leg, all the cleavage he wanted and occasionally side boob, but Heaven forbid we see the former Miss America's belly button!

* CatastrophicCountdown: Scotty has bare seconds to pull off his job in the Jefferies Tube. Quick! Cut to a commercial!

* BabyPlanet: Aversion--the fact that a Luna-sized world has Earthlike atmosphere is one of the clues that something's amiss.

* TheMainCharactersDoEverything: [[SuperDOC Bones]] is among the landing party, so Doctor M’Benga’s back and needs to be helped by [[GhostExtras Doctor Sanchez]].

* ContinuityNod: While they're speculating about what might live on such a strange planet, Sulu mentions the rock creature from "[[Recap/StarTrekS1E25TheDevilInTheDark The Devil in the Dark]]".

* GutFeeling: Scotty's feeling about something being wrong with the ship turns out to be correct.

* ReadingsAreOffTheScale: Said several times of the readings generated by the defense system in action.
