The next morning, the three of them discuss how they're going to stop the city's "purge" . They're planning to use the "imagination gear" to reverse the "gravitational energy" of the gravity system, which will stop the purge for about 38 minutes. The three decide that they'll use this time to "reconnect run" , which means that they won't be able to purge the city. They also decide to "use the imaginary gear" so that they can "redirect run" while the "real" gravity system is still running. This is going to be a lot of work, but it's worth it, says the three.
