Recap / Supergirl (2015) S3E18 "Shelter From the Storm"

Go To

With Reign the only Worldkiller left, Supergirl and J'onn try to stop her before she hunts down Ruby.


  • All Your Powers Combined: Reign absorbed the powers of Purity and Pestilence after they died in the previous episode.
  • Bad Liar: Ruby easily sees through Alex's clumsy lies when she asks her about her mother.
  • Broken Pedestal: Supergirl is this to Lena ever since she asked James to break into her private vault.
  • Crazy-Prepared:
    • Lena has a can of aerosolized Kryptonite on her nightstand, evidently expecting that Reign might come after her in retaliation for her attempts to cure Sam.
    • Lex really went all out for his mansion. It has an Invisibility Cloak which renders it undetectable to Kryptonians (or anyone else for that matter), all the walls are lead-lined, and it has a panic room guarded by numerous traps both inside and out.
  • Cruel to Be Kind: Patricia admits to herself that she was a horrible mother, but all she ever wanted was to keep Sam's identity from her so she could lead a normal life.
  • Depleted Phlebotinum Shells: While Kara distracts Reign, Mon-El crushes Kryptonite into the shape of bullets, which he then loads into a chaingun and fires at Reign.
  • Dramatic Unmask: Reign gets her mask knocked off during her fight with Kara and Mon-El in Lex's vault, revealing to Ruby that Reign is actually her mother.

  • Eureka Moment: M'yrnn helps provide it, by recounting how he reached through to the White Martians. Kara then concludes that she has to appeal to Reign's personal code of justice.
  • Even Evil Has Standards: Kara invokes this, when Reign is about to kill Ruby. Reign's purpose is to dispense justice, but Ruby has no sins. This gets Reign to hesitate long enough for Mon-El to add the Kryptonite to the Gatling gun and disable Reign.
  • Exact Words: Lena wasn't lying to Supergirl about having used up all of Lex's Kryptonite; she just figured out how to make more.
  • Friendship Moment: At the end of the episode, Supergirl apologies to Lena for how she's been acting and gives an affirmation that she does trust her. Sadly, Lena doesn't feel the same.
  • I Choose to Stay: Or rather, Imra convinces Mon-El that he needs to stay in order to sort out his emotions.
  • Advertisement:
  • "I Know You're in There Somewhere" Fight: Patricia tries to reach Sam through Reign. It doesn't work.
  • Internal Reveal:
    • Kara finds out that Lena knows how to make Kryptonite. She's not happy about it. She also learns that James lied about going through Lena's vault.
    • Ruby finds out that Reign is her mom, in the most painful way possible.
  • It's All My Fault: Patricia beats herself up over failing to stop Sam from becoming Reign.
  • It's Personal: Kryptonite to Kara, for obvious reasons. Lena, on the other hand, says that it is personal for her, too, but she wants to help a friend with it.
  • I Want My Beloved to Be Happy: Imra stops Mon-El from returning to the future with her and Brainy, refusing to let him be a slave to duty any longer, and urges him to go back to Earth and help Kara so he can decide once and for all who he loves.
  • Little Miss Badass: Before Ruby sees her mother is Reign, she's clearly quite willing to grab the machine gun and fire on the latter herself when Mon-El and Kara are down.
  • Mood Whiplash: At the beginning of the episode, James and Lena are having a tender moment after sex. It gets ruined when Reign smashes the window.
  • My God, What Have I Done?: Kara is visibly shaken when she realizes how she destroyed Lena's trust in Supergirl with her actions in the last episode.
  • Mythology Gag:
  • Nice Job Breaking It, Hero!: Alex's refusal to tell Ruby the truth about her mom leads Ruby to call her mom using Alex's cell to get some idea of what's happening, thus allowing Reign to track her down.
  • Oh, Crap!: The reaction when the characters find out that Reign has absorbed the powers of Pestilence and Purity.
  • Parents as People: Patricia's apathy and emotional neglect were because she was trying to drive Reign out of Sam. It didn't work.
  • Pragmatic Hero: Lena advocates using Kryptonite to stop Reign.
  • Reality Ensues:
    • Ruby is particularly upset that Alex didn't tell her the truth about her mom.
    • Lena's faith in Supergirl is broken after she asked James to break into her vault.
  • "The Reason You Suck" Speech:
    • Lena gives one to Supergirl over her hatred of Kryptonite, given that it's the only thing on the planet that kills Kryptonians but there are plenty of things that can kill human beings. Kara explains that Lena can't comprehend how excruciating the substance is to Kryptonians. However, Kara also comes off as a Control Freak and naive and entitled not to understand that the average human would want something to counter beings with god-like power, considering we have seen versions of Supergirl with no moral constraint (specifically, Supergirl on Red Kryptonite and Overgirl) and Kryptonians with no qualms murdering humans who have no defense against them (i.e., General Zod, Non, Astra).
    • Later, Supergirl finds herself unintentionally at the end of another when, in her Kara identity, she gets an earful from Lena who vents about being betrayed by her former friend.
  • Self-Made Orphan: Reign kills Patricia, her adoptive mother.
  • The Stinger: In an unknown location, a woman named Tanya steals a book depicting the Worldkillers, evidently owned by Thomas Coville. She makes it out of the building before his followers can stop her.
  • Tempting Fate: Subverted. The Legion prepares to return home, believing that their mission to defeat Pestilence has been completed, unaware that Reign has absorbed the other Worldkillers' powers. Even when they find out about that, however, they know the Blight is still gone because their fellow Legionnaires in stasis are no longer affected.
  • Timey-Wimey Ball: Apparently, changing history and saving an untold number of people from death - and, it is implied, even undoing the death of Imra's sister - doesn't appear to have grave consequences on Earth-38, unlike on Earth-1.
  • Wham Line: When Winnn says it's too bad J'onn will miss Mon-El leaving, Mon-El replies "Tell him I'll see him in a thousand years." Winn chuckles as he leaves but the look on Mon-El's face indicates J'onn is indeed alive in the 31st century.
