In the preceding posts of this series, I established that Preston’s son Robbie is the Guardian of the Threshold, and Mary O’ Brien is its guide. He came to them by way of a dream of his wife, who had been executed for sense offense.
John Preston goes through a second dream and awakening, after looking over his sleeping children and examining a vial of Prozium from his injection gun, musing on the significance. The dream sequence now is Preston witnessing his dead partner, Partridge, being incinerated, while remembering Mary O’Brien saying: “Without love, breath is just a clock ticking.”
Preston awakes to find there is beauty hidden behind his wrapped window: a rainbow of colors from a sunrise, refracted through the rain. I think the scene has deeper implications; although the Tetragrammaton Council suppresses content made by humans, it is unable to suppress the beauty of nature, and Preston realizes he can tear away the facade.
