- Straight: Alice looks into the sky, which is green with three moons. She realizes she isn't on Earth anymore.
- Inverted: Aerith from planet Smeerp looks into the sky, which is blue with white clouds. She realizes she isn't on Smeerp anymore, because the sky isn't green.
- Subverted:
- Alice isn't on Earth anymore, which is hinted several times in the narrative. She finally gets a good view on the sky... which is blue with white clouds.
- Alice looks into the sky, which is green with three moons. The planet she is on turns out to be Earth All Along.
- Double Subverted: Alice isn't on Earth anymore. She finally gets a good view on the sky... which is blue with white clouds. Once Alice acknowledges this, a Space Whale appears swimming across the sky.
- Zig-Zagged: Aerith from planet Smeerp looks into the sky, which is red from the glow of a dying star. She realizes she isn't on Smeerp anymore, because the sky isn't green.
- Averted: Alice isn't on Earth anymore, but she never gets a good view on the sky to become aware of that.
