Event Horizon

"The world is full of liars. People who hide things from us. People who manipulate and control us. I should know. Some of the best liars are people from my own family. But in my life, there was someone who reminded me that truth was always the better way. And she is the person we are here tonight to celebrate. Kara Danvers."

—Lena Luthor's speech on Kara Danvers

Trivia

• This episode takes place one month after "The Quest for Peace".
• In debating the greatest movie villain of all time, Nia suggests Hannibal Lecter (likely The Silence of the Lambs iteration), Brainy suggests Miranda Priestly from The Devil Wears Prada, Kara suggests Voldemort from Harry Potter, and Alex suggests Hans Gruber from Die Hard. Kelly later suggests Hans Gruber, agreeing with Alex.
• When the Superfriends fight Midnight, "Supermassive Black Hole" by Muse plays, which is subsequently followed by Midnight creating a black hole above them.
  • Longtime viewers can pickup that the music is usually a cue for what is happening in a scene, similar to back in Season One in "Manhunter", where lamenting music plays over Kara seeing public opinion of her stay sour after he Red Kryptonite-induced rampage.
