Key passages

  • Gray,” she said dazedly, “it must have been gray⁠—or I couldn’t have seen it like that. I’m colorblind, you see. I can see only shades of gray⁠—my whole world is gray. Like Bat’s⁠—his world is gray too⁠—all gray. But he’s been compensated for he can see above and below our range of color vibrations and⁠—apparently⁠—so can I!”

    Steena explains that her colorblindness, which limits her vision to shades of gray, allowed her to see the invisible alien because it appeared as a different gray against the background.

    Reveals the key to Steena's ability to detect the creature.

  • She was as colorless as a Lunar plant⁠—even the hair netted down to her skull had a sort of grayish cast and I never saw her but once draped in anything but a shapeless and baggy gray spaceall.

    Steena is described as drab and gray, blending into the background of spacer bars.

    Establishes Steena's unremarkable appearance and her gray world.

  • And that is the end of Steena’s story because, as we have been told, happy marriages need no chronicles. And Steena had found someone who knew of her gray world and did not find it too hard to share with her⁠—someone besides Bat.

    The story concludes with Steena's happy marriage to Cliff, implying that her gray world is now shared and accepted.

    Closure on Steena's arc of isolation and belonging.
