- Accidental Innuendo: Supergirl is losing her mind when she feels something good rushing inside her (mind). She describes it as something warm and comforting. It's Geoff, who is trying to contact her mentally. Supergirl thinks Yes! That's it! You're getting there! You're getting through! as she writhes. And Geoff thinks in turn that This is hard work, but I'm making it! How did this go past the Comics Code?
- Ensemble Dark Horse: Although Nightflame didn't make any appearances after this story, her Cyclops flunky is featured in a Supergirl puzzle. And in Supergirl (2015) tie-in comic The Adventures of Supergirl #7, Kara fights the "Wolves of Nightflame".
- Harsher in Hindsight:
- This story states that Kara had an internal death wish. It was written by Marv Wolfman, who fourteen years later wrote Crisis on Infinite Earths #7.
- Linda punches a wall and people wonders if a plane just crashed into the building thirty years before the 9/11.
- Romantic Plot Tumor: Geoffrey "Geoff" Anderson and Supergirl have no chemistry whatsoever, and three issues later Linda would quit her job, move and never see or miss Geoff again. Still Linda says she can feel a closeness she's never felt towards any other man (including her main love interests Dick Malverne and Brainiac 5, apparently), and readers are supposed to regard them as mind-bonded lovers.
- They Wasted a Perfectly Good Character: Nightflame looked cool and menacing -a tall, cloaked, green-clad, sword-wielding sorceress warrior-, her powers were awesome and she was a good Foil to Supergirl because she was the embodiment of Supergirl's dark inner side and her powers were magic-based. She could have become an excellent, recurring villain, but she never turned up again.
