Snowpiercer

In the six months under Wilford, everyone on Big Alice is forced to work in harsh, freezing conditions due to the limited power. With the help of Pike, Ruth leads the resistance in hiding.

On Snowpiercer, Layton's crew decides to reconnect with Big Alice before heading to the final location shown by Melanie's data: the Horn of Africa.

Snowpiercer lures Big Alice into a rail yard, losing four cars to an attack by Wilford while Strong Boy and several other revolutionaries are captured and tortured by Kevin.

Snowpiercer comes across three disconnected Big Alice cars that Alex and Bennett must board and detach the clamps; the cars contain the bodies of the people that Wilford had culled years earlier, including Alex's friend Shilo.

As Zarah goes into labor, a series of terrorist attacks occur targeting Layton; it's revealed that Pike is behind them and trying to assassinate Layton due to his preference of Ruth as a leader and his blaming Layton for the people that they've lost.

With the help of LJ, Miss Audrey sneaks in to see Wilford who is left a broken man from his experiences under the suspension drug; now believing in the possibility of New Eden, Wilford studies the dragon blood tree and the Horn of Africa.

Comatose from his head injury, Layton dreams that he is part of a resistance led by Wilford on a dystopian Snowpiercer. Layton's various friends and enemies push him to confront what is keeping him trapped.

Bennett and Alex discover the trail of a small autonomous track maintenance vehicle leading back to a hanger on the track where they had left Melanie, supporting Wilford's theory.

Over the course of six months, Melanie keeps herself alive in a track scaler by using the suspension drug for the Drawers. Snowpiercer manages to catch up to Melanie's vehicle and rescues her, discovering Melanie to be still alive.

Melanie and Layton prepare for war over control of the train. Wilford's forces, including Bojan who is revealed to be still alive and Wilford's new cold man, take control of the Night Car and revel in the chaos.
