With the revelation that Glimpse allows the user to step through mirrors to alternate realities, the group meets up to explore the empty world on the other side of Jake's bedroom mirror.
After the teenagers are rescued by a Beta World resident, Travis, they are taken to his home in a church basement. Travis recounts his story of how Beta World ended, and the horrors now lurking in the dark.
Events transpiring a year before the teens stepped into Beta World may give clues as to how Jason acquired his ability, where Glimpse came from, and who potentially created the Banshees.
