Layton demands to use Big Alice to rescue Liana. Ruth, now Mayor of New Eden, refuses because it's the town's power supply. Layton makes Javi jury-rig a solution, giving them three weeks of electricity.

Big Alice catches up to Snowpiercer. Milius radios them, inviting Layton over. Sensing a trap, Layton and Josie sneak onto Snowpiercer. Nima is worried Layton will be gassed and attempts to disarm the Greenhouse Car.

Layton learns who was responsible for the experiments on Josie and Liana, before also finding out who froze the world.
