Supergirl and the others finally find out where Lex and Nyxly are hiding, and head out to take back the Totems. Meanwhile, Nyxly finds the Truth Totem and uses it to confirm whether Lex is sincere in his love for her. Elsewhere, William is in hot water over something Andrea did, Alex is having a hard time coming to grips with how to raise Esme, and Brainy finds out he has to return to the 31st Century.
Tropes:

- Beam-O-War: Between Kara, Nyxly and Lex.
- The Bus Came Back: The more logical, cold Brainy from an alternate universe comes back.
- Butt-Monkey: Wearing a Lexosuit, Mitch disables J'onn with an energy blast and then smarts off about how easy it was. J'onn regroups and absolutely trashes the Lexosuit, leaving Mitch unconscious. Shortly after that, the self-destruct system destroys Mitch's ship. And finally, an irritated Lex cuts off Mitch's musings and tells him to restock the fridge.

- Courtly Love: Lex actually wrote several poems for Nyxly, which are leaked by Andrea.

- Dies Wide Open: William dies with open eyes.
- Downer Ending: The episode ends with Nyxly having kidnapped Esme from beneath the Superfriends' noses and Lex murdering William.

- Extremely Short Timespan: Alex makes mention of not seeing the rose tattoo when they were giving Esme a bath the previous night. Given there's been no indication the tattoo appears and disappears intermittently, this seems to indicate the bachlorette party takes place literally the day after Alex and Kelly proposed to each other.
- Evil Is Petty: Lex shoots and kills William as revenge for his journal being leaked to the press.
- The Ghost: Brainy has a call with Winn, but the latter doesn't appear in person.

- Mama Bear: Alex gets into a dispute with Kara when the latter advises her to put a power dampener on Esme, which Alex thinks of as an unasked for parenting advice. They do make up again though.
- My God, What Have I Done?: Andrea at the end of the episode when she receives the video of William being shot by Lex for supposedly being the one to leak his journal to the media.
- Mythology Gag: Nia wanting to just live in the 31st Century in order to stay with Brainy is exactly what the Justice League version of Supergirl did in the Unlimited seasons.
- Nice Job Breaking It, Hero: Andrea leaking Lex's journals to the press under William's name directly led to Lex killing William.
- Portmanteau Couple Name: In-universe. A TV presenter dubs Lex and Nyxly "Lexly".
- Power Incontinence: When getting picked on in school, Esme's powers have a minor freak out.
- "The Reason You Suck" Speech: William lays one into Andrea when he confronts her for putting Lex's journal on the news.William: I became a journalist to tell real stories, to report the truth. Your "ends justify the means" excuse makes you just as bad as Lex. You both have no ethical code. I was hoping that you'd wield CatCo's power and influence for good, but instead, your pathological obsession to be number one made you selfish and shortsighted. What's important is what you stand for, what you contribute to make the world a better place. And you, Andrea Rojas, stand for nothing.
- The Reveal:
- Otis talking to William about planning to build an army of Lexosuits last episode was an intentional ploy by Lex.
