History Recap / Supergirl2015S1E20BetterAngels

* DaylightHorror: In contrast to the previous episode (which took place entirely at night), this episode takes place during the daytime following the prologue, but the horrors of Myriad are actually much ''worse'' this time around.

Supergirl is forced to do battle with an unexpected foe and must risk everything--including her life--to prevent Non and Indigo from destroying every person on the planet.

** [[{{Film/Supergirl}} The Omegahedron]].

* NoEndorHolocaust: If everyone on Earth suddenly gets a painful, disabling headache due to Myriad, this should lead to loads of car crashes and other accidents, with thousands of casualties, yet nothing like this is implied to have have happened.

* RealityEnsues: For the first time in this series--and for the first time in any live-action production related to Superman--we learn that Supergirl can't fly in the vacuum of space (due to requiring "thrust") or breathe without an atmosphere, while most Superman-related media allow Kryptonians to fly through space and at least hold their breath far longer than any normal human. This is fairly close to the ''Film/ManOfSteel'' portrayal, in which Superman has similar though not explicitly spelled out limitations.

** General Lane gives Max the Omegahedron Core, which has enough energy to power a city even though it's the size of a baseball.

* GenreSavvy: Cat and James both note with concern how final Kara's messages for them sound. James calls Lucy to tell her about Kara's odd behavior, very worried.

* ActorAllusion: Cat refers to the ending as Kara's ''Film/WorkingGirl'' moment. Creator/HarrisonFord, who was referred to in the last episode starred in that movie (and is married to Cat's actress, Calista Flockhart).

* ActorAllusion: Cat refers to the ending as Kara's ''Film/WorkingGirl'' moment. Creator/HarrisonFord, who was referred to in the last episode starred in that movie (and is married to Cat's actress IRL)
* ArcWords: "Stronger together" and "Blood bonds us all" return from their respective episodes.

* BeamOWar: Kara and Non's fight finally climaxes with this.

* BookEnds: The season started off with Kara being sent to Earth and her pod being opened by Superman. It ends with another pod which she opens to find something shocking.

** In "World's Finest", Lucy mentioned several people who had been hospitalized as a result of electrical imbalances in the brain. This episode shows that not only was Myriad definitively responsible for that, it can be dialed up to cause death.

* ConvenientComa: Superman is in a coma for the bulk of the episode and only contacts Kara via messenger in the end.

** When Supergirl asks why they just left Fort Rozz there, General Lane responds "You try moving a one million ton alien spacecraft." At the end, Supergirl does just that.
** Kara's escape pod was emphasized near the end of the episode. At the very last scene, a Kryptonian escape pod once again crashes to Earth.

** J'onn is put in handcuffs by a fearful military, and eventually causally snaps the handcuffs to show he was only staying in custody to be polite and help them trust him, much like Superman in ManOfSteel.
** Maxwell Lord is given the power source of a MindControl device. In the comics, MindControl is his superpower. Possibly also ForeShadowing

* PreSacrificeFinalGoodbye: Before going off to fight Non and Indigo, Kara gives one each to Winn, Cat, and James, unnerving each of them to different degrees, as they don't know that Kara's about to go into a fight she knows she may not come back from. Alex gets one just before Kara takes Fort Rozz into space, as Kara wasn't willing to say goodbye to her when she thought there was a chance she might come back.

* RealityEnsues: For the first time in this series -- and for the first time in any live-action production related to Superman -- we learn that Supergirl can't fly in the vacuum of space (due to requiring "thrust") or breathe without an atmosphere, while most Superman-related media allow Kryptonians to fly through space and at least breathe far longer than any normal human. This is fairly close to the ''Film/ManOfSteel'' portrayal, in which Superman has similar though not explicitly spelled out limitations.

** For the second episode in a row we sorta-kinda see Superman. WordOfGod (the producers, in an interview published after the episode aired) is that having Superman appear in full has not been discounted for a future episode. The same thing was said regarding The Flash crossover, and it happened.

* TalkingIsAFreeAction: Justified when Kara says farewell to Wynn, James, and Cat, since the source of the Myriad signal hadn't been found yet. Not so much for Kara's conversation with Alex just before her attempted HeroicSacrifice, flying Fort Rozz up into space. They were seconds away from the messy death of every human on the planet... so she stops for a long chitchat.

* YouCalledMeXItMustBeSerious: Cat finally calls Kara by her right name, after promoting her.

* ActorAllusion: CaThe refers to the ending as Kara's ''Film/WorkingGirl'' moment. Creator/HarrisonFord, who was referred to in the last episode starred in that movie (and is married to Cat's actress IRL)

* ArtisticLicensePhysics: Kara's inability to fly in space is due to the supposed lack of gravity preventing her from generating thrust. Except, there is actually gravity in space, albeit much weaker gravity than on Earth.

* StealthPun : [[ComicBook/LexLuthor A-Lex in kryptonite-powered armor]] fights a Kryptonian.

* YouCalledMeXItMustBeSerious: Cara finally calls Kara by her right name, after promoting her.

* {{Foreshadowing}}: When Supergirl asks why they just left Fort Rozz there, General Lane responds "You try moving a one million ton alien spacecraft." At the end, Supergirl does just that.

** [[Film/BatmanVSupermanDawnOfJustice A Kryptonian and a human armed with PoweredArmor and Kryptonite weapons are manipulated into fighting.]]

* NoEndorHolocaust: If everyone on Earth suddenly gets a painful, disabling headache due to Myriad, this should lead to masses of car crashes and other accidents, with thousands of casualties, yet nothing like this is implied to have have happened.
