History Recap / Supergirl2015S2E6Changing

* WholePlotReference: A team of researchers in the arctic encounter an alien life form that causes shape-changing and personality loss. Sounds like ''Film/TheThing''.

* BadassBaritone: James's altered voice in his suit is pretty deep and gruff.

* GoingToGiveItMoreEnergy: Kara kills Jones by having him absorb [[ILoveNuclearPower plutonium-239]], which overloads him until he [[DefeatEqualsExplosion explodes]].

** [[WesternAnimation/YoungJustice It's not the first time]] that M'Gann has given someone a life-saving blood transfusion.

* RealityEnsues:
** Mon-El goes out of his way to fight Jones in public without any way to obscure his identity. By the end of the episode, he is captured by Cadmus, who can easily identify him.
** Maggie turning down Alex, as Maggie just got out of a relationship, and Alex needs to figure herself out before jumping into one; Maggie knows that such pairings rarely turn out well. Also the reality that the person you have a crush on will not always reciprocate those feelings or will not immediately want to be in a relationship with you just because you like them.

* {{Adorkable}}: Drunk Kara. Sober Kara is already really adorkable on her own, but getting drunk severely amplifies her adorable dorkiness. Even Alex is amused.

* ComingOutStory: Alex tells Kara hers--Maggie forcing her to confront her feelings has stirred up a lot of buried emotions and half-remembered attractions to other girls (though nothing she ever acted upon), especially her best friend from high school. Kara is surprised, but supportive.

!!Tropes in this episode:

* ArtisticLicenseHistory: Scandinavia was not in its Bronze Age in 3000 BC, and even if it had been vikings weren't a thing until the Iron Age. It is being said by an environmental scientist in a dismissive manner however.

* BadassBaritone: James' altered voice in his suit is pretty deep and gruff.

** In a corner of the DEO, Jones hacks up the alien parasite, which crawls out his mouth, up his face, and into his ear.
** Kara's body after being drained by Parasite is also a pretty gruesome sight, with focus on FacialHorror.
* ClarkKenting: Averted for James's hero identity as he has a mask that covers his whole face and voice-changer as well. And his suit is even lead-lined so his identity can't be found with X-ray vision.

* ComingOutStory: Alex tells Kara hers.
* CompositeCharacter: Jimmy Olsen is given the superhero alter ego of the Guardian, who in the comics is a completely different person.
* DidNotGetTheGirl: Unfortunately for Alex, Maggie doesn't return those romantic feelings.

* GargleBlaster: Aldebaran rum. It's straight up lethal to humans and strong enough to get a Kryptonian drunk with one shot.

* LockedOutOfTheLoop: Kara doesn't know that James is Guardian because his armour is made of lead so her powers can't see through it.

** At the end of the fight with Parasite, Supergirl asks Guardian who he is. His answer? "[[Film/{{Superman}} A friend.]]"

* PuppeteerParasite: Rudy Jones seemingly doesn't really have control over anything the Parasite makes him do.

** Maggie turning down Alex as Maggie just got out of a relationship and also because as she tells Alex that she needs to figure herself out before entering a relationship since she has just came out to Kara and herself and them becoming a couple wouldn't work until she does. Also the reality that the person you have a crush on will not always reciprocate those feelings or will not immediately want to be in a relationship with you just because you like them.

** When Parasite is sent knocking back from Guardian's AttackReflector, Winn calls the creature "[[UsefulNotes/McDonalds Grimace]]".

* UnsuspectinglySoused: Aldebaran rum is served to Kara and Mon-El as "a refreshing cocktail" for Kryptonians and Daxamites, but one shot is enough to get Kara completely and utterly wasted.
* VampiricDraining: Rudy Jones sucked the life force out of his coworkers after getting infected by the alien parasite.

* YouAreNotAlone: How Kara tries to encourage Alex after her coming-out.

** Mon-El goes out of his way to fight Jones in public without any way to obscure his identity. By the end of the episode, he is captured, by Cadmus.

** When Parasite is sent knocking back from Guardian's AttackReflector, Winn calls the creature "[[Series/SesameStreet Grimace]]".

** Kara gives one to Mon-El when she finds out he works as an enforcer.

* StrawmanPolitical: Dr. Jones is a WellIntentionedExtremist targeting threats to environmental efforts, which means an advocate for a conference on climate-change denial is referred to as an amassing of evildoers and shown practicing a speech dismissing zealous liberals ej route.
