Gunneson attacks Molly in her home, but he escapes and the Threshold team tracks him to a water-treatment plant, where they encounter another infected person. And Molly fears she may be more affected by the alien signal than she first thought when her blood congeals into the fractal alien pattern.

An inmate at an Ohio psychiatric institute escapes and Molly believes he may have been infected by the aliens after paintings of glass trees, like the ones in her dreams, are found in his cell. The inmate, who has been incarcerated since 1979 for burning down his house with his family inside when he was 13, then breaks into a woman's ground-floor apartment and starts digging through the floor for a mysterious object he buried 26 years ago.
