By using Madeline and other resources, the Midnighters find out that on the night of Samhain (Halloween), the Secret Hour will expand, and more of the Earth will be sucked up.
This is because there is a "rip" in true midnight, which allows non-midnighters to slip into the blue time, that is expanding like a seam in fabric.
True midnight (usually confined to the secret hour) will last for the whole day, and all humans and creatures within it will be awake, no longer 'stiff'.
To Jonathan and the whole Midnighter's teams dismay, she will forever be trapped in the blue time, only able to live for an hour of every day.
Jessica's parents become very sad about their daughter's "disappearance" and are still grieving her loss when Beth comes to visit Jess for the last time.
