Screen Rant has an exclusive clip from Snowpiercer's season 3 finale where Andre Layton (Daveed Diggs) meets with the Tail and Third Class to answer for his New Eden lie. In Snowpiercer season 3's penultimate episode, "A Beacon For Us All," the miraculously rescued Melanie Cavill (Jennifer Connelly), betrayed Layton during the train's farewell party and publicly revealed that Andre deceived the passengers about New Eden. Cavill unilaterally acting to save Snowpiercer, as she sees it, plunges the train back into the possibility of another war for control. Worse, Mr. Wilford (Sean Bean) used the opportunity to escape confinement and now he's at large somewhere aboard Snowpiercer.

Layton was desperate to give Snowpiercer's passengers hope for New Eden, which is how he justified his lie. In Snowpiercer season 3's premiere, Layton had a near-death experience in a Korean nuclear plant where he hallucinated a vision of a dragon's blood tree, which he believed pointed the way to New Eden, which is the warm spot that can support life Melanie theorized. After he regained control of Snowpiercer from Mr. Wilford, Andre promised the passengers that Snowpiercer was real but he lied that he had been there. Asha (Archie Panjabi), a survivor Layton rescued in Korea, was a key part of his deception because she also lied that she was from New Eden. But Pike (Steven Ogg) doubted Layton and tried to assassinate him, later confirming his suspicions that Andre lied about New Eden. Layton was left comatose after fighting Pike to the death and in his dreams, he realized that he made New Eden up. Yet Snowpiercer's course was set and Layton planned to gamble that New Eden is real - until Melanie exposed him.

In Screen Rant's exclusive clip from Snowpiercer's season 3 finale, "The Original Sinners," Layton meets with the assembled members of the Tail and Third Class in Big Alice. Andre is flanked by his lieutenants, Bess Till (Mickey Sumner) and Josie Wellstead (Katie McGuinness), and the former Train Detective comes clean to the people about his lie. You can watch the clip below.

After Layton's mea culpa, he wisely referenced how life aboard Snowpiercer was under Melanie Cavill's rule in the years leading up to season 1. After Cavill stole Snowpiercer from Mr. Wilford, she spent seven years posing as the Eternal Engineer while maintaining the train's brutal class structure and order. This included the inhumane treatment of the 400 stowaways in the Tail, Layton and Josie among them, who forged a close-knit society. The Tail eventually followed Layton to war with Melanie and won control of Snowpiercer. By admitting his lie and reminding the Tail of life under Cavill, Layton succeeded in gaining their support for the war to come.

With Melanie's takeover of Snowpiercer's engine, Layton and his loyalists, which also includes Melanie's daughter Alex (Rowan Blanchard), Bennett Knox (Iddo Goldberg), and the mother of his child, Zarah Ferami (Shiela Vand), have control of Big Alice at the opposite end of the 1,029-cars-long train. But besides matching wits with Melanie, there's also Mr. Wilford who has to be reckoned with. Having shored up his support from the Tail, Layton is poised for another bloody war to take back Snowpiercer in the season 3 finale.
