History Recap / StarTrekS1E4TheNakedTime

* ObliviousGuiltSlinging: While affected Chapel tells Spock that "the men from Vulcan treat their women strangely. At least, people say that, but you're part human too. I know you don't... you couldn't hurt me, would you?" Spock [[NotSoStoic appears to be shocked by her words]], and later angsts how he could never tell his mother that he loved her, because he respected his Vulcan traditions.

* MurderWater: Contrary to the episode synopsis you just read, the episode itself doesn't have the cause to be a virus--that was the retcon used in the "revisiting" to cover the fact that the central premise of "The Naked Time" fell squarely into ScienceMarchesOn: polywater, a kind of high-viscosity, low-freezing point water that would tend to make other water into its own type. It's not actually ''sentient,'' but it is extremely dangerous, can move in ways that should be impossible, and is (a type of) water.

** Seen when the first crewman is infected--the bloody water moves ''upwards'' towards his hand of its own accord.

The ''Enterprise'' has arrived at the ice planet Psi 2000 to document its impending collapse. Spock and [[RedShirt some other loser]] beam down in Hazmat suits to investigate why a laboratory on the planet shows no life signs: turns out, everybody froze to death because someone left the door open and nobody cared enough to correct that. While Spock is investigating the corpses, his companion [[TooDumbToLive unwisely]] removes his glove to scratch his nose, allowing a strange red fluid to drip onto his hand.

Back on board the ''Enterprise,'' the RedShirt starts acting strangely, in turns belligerent and depressed. He gets into a fight with Sulu and a guy named Lt. Kevin Thomas Riley, brandishes a dinner knife at them, and mildly injures himself. However, when [=McCoy=] operates on him, he dies, seemingly losing his will to live. [=McCoy=] is perplexed, as the victim was in good health and was previously known as a strong-willed individual. The reason for his odd behavior soon becomes apparent: he carried a virus that removes inhibitions (and makes one extremely sweaty, incidentally).

Chaos engulfs the ship as the virus spreads: crew members act carelessly, laughing maniacs run around the halls painting creepy messages in red paint, Sulu menaces passersby with a fencing sword, and Spock enters a crippling depression. Worst of all, Riley has locked himself in the engine room, hijacking the PA system to make bizarre announcements and advise women on hair and makeup styles, stranding the ship just as the planet is breaking up, threatening the ''Enterprise.'' Kirk and Scotty try to break into the engine room while [=McCoy=] cooks up a vaccine. However, by the time Scotty gets the door open, it's revealed that the engines were stopped completely and that restarting them would take more time than the planet has. Desperate, Kirk orders Scotty to... [[{{Technobabble}} do something involving matter/antimatter annihilation]] to get the Enterprise out of the way. Scotty cries that it only has a [[MillionToOneChance 1-in-10,000 chance]] of not blowing them to smithereens (so, naturally, it will work perfectly), but he needs Spock's help. Kirk tries to [[GetAHoldOfYourSelfMan slap Spock out of his funk]], but Spock only recovers when Kirk empathizes with him under the virus's influence and reveals the heavy burden of being Captain of the ''Enterprise''--contrary to popular belief, ''you can never get laid,'' at least not with crew members. [=McCoy=] cures the crew and the ship escapes, but with a strange side-effect: it travels about three days backwards in time, in the series' first instance of time travel.

!!Tropes

* ArtisticLicenseAstronomy: Why would a planet break up due to it's sun going dark? Also, the universe isn't old enough for white dwarves or any other star to go dark, either, if it is meant that the star turned into a black dwarf.
** A 'dark star' was an early name for a black hole, so it's possible that's what they're referring to, with the planet breaking up as it falls into the black hole's gravity well.

* RunningAwayToCry: Spock locks himself away when the virus breaks down his emotional control.

* TooDumbToLive: Taking off your glove, getting some weird liquid on your hand, and then rubbing your nose? If the virus hadn't gotten him, this guy doubtlessly would have found some other way to kill himself in a few days.

* WorldOfHam: Everybody under the influence of the virus starts gobbling up the scenery, nobody better than Riley, though.

* TheChainsOfCommanding: Kirk's role as TheCaptain won't let him live his own life. There's a gorgeous blonde right under his nose but he can't get involved with a subordinate.

** No-one on the Bridge notices that the helmsman has wandered off until an alarm sounds.

* TheChainsOfCommanding: Kirk's role as TheCaptain won't let him live his own life.

* GetAholdOfYourselfMan: Kirk attempts to slap Spock back into a steady state of mind. All it does is get Spock mad enough to slap him back, with enough force that he goes flying across the table.

* LoveIsAWeakness: Spock had to hide his love for his mother, who was the [[LonelyInACrowd sole human]] on a world where the expression of love was regarded as disdained. Kirk vents about how his love for the Enterprise is AllTakeAndNoGive.

* LoveIsAWeakness: Spock had to hide his love for his mother, who was a sole human on a world where the expression of love was regarded as 'bad taste'. Kirk vents about how his love for the Enterprise is AllTakeAndNoGive.

-->'''Spock:''' I respected my father, our customs... I was ashamed of my Earth blood... ''([[GetAHoldOfYourselfMan Kirk slaps him!)'' Jim, when I feel friendship for you, I'm ashamed!

SPOCK: The readings are perfectly normal for me, Doctor, thank you, and as for my anatomy being different from yours, [[SnarkToSnarkCombat I am delighted.]]

* {{Foreshadowing}}: When Spock says they've accidentally invented TimeTravel, Kirk muses that they may risk it again someday.
* AFriendInNeed: A NotHimself Spock talks of the shame he feels whenever he feels friendship towards Kirk. When Kirk himself starts to break down and pleads for help, it's only then that Spock pulls himself together.

* HesDeadJim: Though Tormolen is on a biobed at the time.

* LoveIsAWeakness: Spock had to hide his love for his mother, who felt alone on a world where the expression of love was regarded as 'bad taste'. Kirk vents about how his love for the Enterprise is AllTakeAndNoGive.

* MadnessMantra: Spock tries to ward off the effects of the disease by repeating "I am in control of my emotions" and reciting multiplication tables.

* ItsTheOnlyWay: Cold starting the warp engines involves the use of a (at this time theoretical) method of combining matter/antimatter to create an implosion instead of an explosion.

** When Kirk does order a HyperspeedEscape escape, Kirk is asked for a direction. He replies, [[TimeTravel "Back the way we came."]]

** When Scotty tells Spock they still need four minutes to get things right, Spock just tells Kirk that they're ready as they've run out of time and just have to risk it.

* ObliviousGuiltSlinging: While affected Chapel tells Spock that "the men from Vulcan treat their women strangely. At least, people say that, but you're part human too. I know you don't... you couldn't hurt me, would you?" Spock appears to be shocked by her words, which appear to be him falling under the influence himself, but later he angsts how he could never tell his mother that he loved her, because he respected his Vulcan traditions.

* FailsafeFailure: After decades of viral outbreak movies, the NoBudget nature of the HazmatSuit sticks out when Tormolen is able to casually raise his hood to scratch his nose, revealing that his suit has no independent air supply. It's possible it was only meant to be a thermal suit, as the planet is covered in ice after it's sun 'went dark'.

* OhNoNotAgain: Kirk's reaction to Lt. Riley's announcement that he is going to sing another [[HollywoodToneDeaf rendition]] of "I'll Take You Home Kathleen."

* TemptingFate: Scotty assures Kirk that their warp engines can get them away from the disintegrating planet [[HyperspeedEscape in an instant.]]

* RedAlert: Alert Condition Baker Two puts the ship into LockDown.
