History Recap / StarTrekVoyagerS4E7ScientificMethod

* ThisMeansWar: Or as Janeway puts it, "This ends '''right now.'''"

** After Seven of Nine detects the invisible aliens she rushes to the Ready Room to warn the captain, only to find the aliens already there and doing experiments Janeway as well.

'''Doctor:''' Always looking for the simple fix. Sometimes there's no substitute for intensive osteopathic pressure therapy. You're fortunate to have a masseur who can work all day without tiring. ''(Janeway gets OhCrap look)''

* LightmareFuel: Among all the MedicalHorror in this episode, there's comic scene involving Janeway getting an overly vigorous massage from the Doctor.

* AttackPatternAlpha: The Doctor isolates Comm Frequency Epsilon Two from Voyager's communication system so he can secretly communicate with Seven.

* GodzillaThreshold: Faced with aliens who can instantly kill the crew if they try to resist, Janeway flies Voyager on a desperate course into a potentially deadly stellar phenomenon to get rid of them.

* HangoverSensitivity: Janeway door chimes while she's plagued by a headache, and she gripes, "Remind me to lower the volume on that door."

* PlayingWithSyringes: The aliens come across as an entire civilization who crossed the MoralEventHorizon long ago and have just kept on going. They routinely do medical experiments on sentient creatures, mutilating, torturing them, and even killing them if they feel it will benefit their medical research to do so. They feel completely justified in their actions and not only do they feel no remorse or regret over their actions, they feel that what they do is noble and beneficial. Genetically deforming, maiming and killing the crew of Voyager is the NightmareFuel evidence of their crimes and that is only the tip of the iceberg. What is really terrifying is that their flimsy justifications allow them to murder entire societies with impunity and go on torturing and killing as many sentient creatures as they feel is necessary for their "research."

* SpaceshipSlingshotStunt: Voyager is flown between binary pulsars fast enough to escape out the other side without being torn apart by gravitational stress.

* MeaningfulEcho: An InUniverse version when [[CharacterDevelopment B'Elanna realises she's giving the same speech to Seven of Nine about following protocol that Captain Janeway once gave to her.]] She becomes a little more patien with Seven after this.

* AnachronismStew: Hiding in the [=DaVinci=] program on the holodeck, the Doctor tells the computer to replicate a Type IV micro-inducer. Instead of placing it on the rack of other medical instruments he alread has, it gets dumped into a bucket hanging from the side of the table.

* DisappointedInYou: B'Elanna and Tom are surprised when Janeway lets them off with a scolding for their behaviour, but privately concede they need to be more professional during working hours.

* AnachronismStew: The Doctor replicates a Type IV micro-inducer into a bucket in the [=DaVinci=] program.
* ApologyGift: Tom replicates some FlowersOfRomance for B'Elanna to apologize for missing their last planned make-out session.

* DisappointedInYou: B'Elanna and Tom are surprised when Janeway lets them off with a scolding for their behaviour.

* EverybodyKnewAlready: At the beginning, Tom and B'Elanna are trying to keep their new relationship a secret -- though the fact that they've been taking every available opportunity to make out isn't helping. When a cranky Janeway summons them to her office to give them a dressing-down for acting like a pair of hormonal adolescents, they initially assume Tuvok (who caught them at it in Engineering) told on them, but she informs them that the whole crew has been gossiping about them.
* ElderlyAilmentRambling: A prematurely aged Chakotay is stuck in Sickbay along with Neelix, both complaining about their ailments to each other. Chakotay goes bald, his eyesight is failing, and has severe arthritis.

* FlowersOfRomance: Tom materializes himself into the Jeffries tube where B'Elanna is working, holding a replicated bouquet.
* {{Foreshadowing}}: Janeway complains that her HeadacheOfDoom is like needles drilling into her skull. When Seven looks at her through SeeThruSpecs, the Borg is horrified to see aliens doing exactly that.

* GodzillaThreshold: Faced with aliens who can instantly kill the crew if they try to resist, Janeway flies Voyager on a desperate course.

* HeadacheOfDoom: Janeway suffers from a near-crippling headache that she compares to "hot needles driving into [her] skull". Unbeknownst to her, that's exactly what's happening, courtesy of out-of-phase alien scientists conducting experiments on her and the crew.

* MakeOutKids: Tom Paris and B'Elanna Torres make up for years of UnresolvedSexualTension by making out constantly.
* MakingLoveInAllTheWrongPlaces: Tom beams to a Jeffries tube where B'Elanna is working so they can make out. Later they get so impatient they start doing it on a console on the upper deck of Engineering. And we know from a [[Recap/StarTrekVoyagerS5E21SomeoneToWatchOverMe later episode]] that they can both be [[TheImmodestOrgasm quite noisy]] during [[RightThroughTheWall these times]] (though in this particular instance they don't go all the way).
* MamaBear: Captain Janeway isn't going to let aliens take control of her crew if she has anything to do with it.
* MeaningfulEcho: An InUniverse version when [[CharacterDevelopment B'Elanna realises she's giving the same speech to Seven of Nine about following protocol that Captain Janeway once gave to her.]]

* NervesOfSteel: Seven in the turbolift has to avoid reacting when an alien sticks a probe into her neck.

* NotHerself: Captain Janeway being very irritable.

* OvercomeWithDesire: B'Elanna and Tom resolving years of UnresolvedSexualTension.

* StupidEvil: It's unclear what scientific value driving a woman in charge of a starship batshit insane would have, and it's certainly unclear what scientific value triggering her MamaBear instincts would have, but the Srivani do it, with deadly results.
* SwissCheeseSecurity: Averted; Tuvok quickly detects Seven's attempt to create an overload.

* RecycledPremise: [=TNG=] had a few "aliens doing experiments on the ship's crew ForScience" episodes, such as [[Recap/StarTrekTheNextGenerationS6E5Schisms "Schisms"]] and [[Recap/StarTrekTheNextGenerationS2E2WhereSilenceHasLease "Where Silence Has Lease"]]. This episode is more or less ''Voyager'''s take, but with a particular focus on BodyHorror.
