Alternate Lex Luthor: (about Lois) The insolence. The outright rudeness. She's definitely the genuine article.
Lois: Hey, I'm not finished!
Alternate Lex Luthor: I beg to differ.
Alternate Angela Chen: Lois? Lois Lane? My God, it's you, it's really you!! You're alive, after all these years! Can you loan me a dollar?
Lois: So, I am Lois Lane, but I'm not the Lois Lane that you knew...
Alternate Superman: Ever since you-- she died I've wondered if there were other dimensions out there. Other version of me... and you.
Lois: Hold it! I may be a lot like your Lois, but you're nothing like the Superman I know! He's no tyrant.
Alternate Superman: I had to take control, there was no other way. For too long I fooled myself into thinking I was just doing a simple clean-up job. And if I did enough good, people would follow my example. I didn't realize it was a war. And suddenly you were a casualty of that war. And I knew I had to stop it by whatever means possible.
Alternate Superman: You never knew what I felt about you. I never knew, till you were gone.
Lois: (slaps him) You could've said something. We could've talked about it and figure it out! Now look at you... married to Luthor...
Alternate Superman: I never thought I'd lose you... twice.
Lois: Will it change anything?
Alternate Superman: For me, but not for Metropolis. Not his time.
Superman: So that was me?
Lois: Yes. And... no. It-it's complicated. I could explain it over dinner.
Superman: Dinner? Are we getting a little personal?
Lois: Better now than never...
If Luthor had the Kryptonite in his pocket, Superman should have felt it before he took it out.
How exactly was Lois climbing up the statue of Superman's head, when there was nothing to grasp; it had a smooth surface?
Lois kicks Mercy repeatedly with her injured leg.
Aldous Huxley's Brave New World
The title of this episode is a spun on Aldous Huxley's novel Brave New World, which satirically describes a 26th-century in which human society has become "idealized", people made in test tubes rather than born and with unhappiness and pain bred out of them altogether. Huxley uses the story of an outcast named Bernard and a "Savage" named John to point out how this conformist utopia isn't as wonderful as we might think. The origin of the phrase "Brave New World," however, comes from The Tempest, Act 5, Scene 1, by William Shakespeare.
In this episode, someone very important to Superman (Lois) dies due to him not being there for her, which causes him to go into dictatorship. This nearly the exact plot of the Darkwing Duck
episode "Time and Punishment
." In "Time and Punishment
," Gosalyn, Darkwing's adopted daughter, is accidentally sent into a time machine into the future. Darkwing believes that she ran away due to him forbidding her to go with him on a mission. This makes him depressed, until he saves a little girl, and becomes Darkwing Duck again. However, had already imprisoned every crook in town, so he becomes a dictator, who arrests people for being out past the town currfew (just like in this episode). Coincedentally, Darkwing Duck is a parody of Batman, and his rogues gallery seem to parodies of Superman villains, such as Quacker Jack (who uses killer toys, like Toyman), Negaduck (who is the exact opposite of Darkwing Duck, much like Bizzaro is to Superman).
