Editing Melanie Cavill (section)

===Revolution===
At Layton's request, [[Miles]] reveals to [[LJ Folger]] the truth about Melanie. Melanie later coaches Miles by driving the train himself and the two discuss their lost families. When Miles brings up still having his Tail mom Josie, Melanie shows a moment of guilt before they are interrupted by First demanding answers after LJ reveals to her parents what she has learned. Melanie is arrested and imprisoned in Hospitality but manages to trip an alarm warning Bennett to lock down the engine room. Javi abandons the engine while Bennett locks himself inside and tells Commander [[Grey]], his men and Ruth that the real Mr. Wilford has been dead since boarding and that Melanie "took the train."

Ruth later visits her imprisoned friend in Hospitality for answers and Melanie admits that she abandoned the real Mr. Wilford to die in Chicago at departure. Melanie explains that she is the true visionary behind ''Snowpiercer'' while the real Mr. Wilford "sold tickets" and didn't believe in the survival of the human race, instead of desiring to spend the rest of his life surrounded by opulence. Believing that the train wouldn't survive one revolution with him in charge, Melanie abandoned Mr. Wilford to die and took his place and identity to ensure the survival of humanity. Upset, Ruth announces that Melanie will be executed for her crimes the next day before leaving Melanie alone.[[Melanie Cavill#cite%20note-revolutions-2|[1]]]

Melanie is subsequently imprisoned with captured revolutionaries awaiting their executions. However, she is rescued by Javi and Jinju and makes her way down train where Melanie is captured by Layton's people. Donning more casual clothes for once, Melanie offers a solution to the problem: disconnect several cars containing the Jackboot army and the Folgers. Having only ever intended to keep the last of humanity safe, Melanie knows that her way didn't work and wants to try Layton's way with him in charge. With little other choice and Miss Audrey believing her, Layton agrees to Melanie's plan.

Melanie gives Layton her access implant and contacts Bennett in the Engine to fill him in on the plan. Melanie explains to Layton that they must disconnect safety switches on either side of the planned disconnection, requiring Layton to infiltrate the forward section. When the time comes, Melanie pulls her switch down train and watches as the forward part of the train pulls ahead. Layton eventually pulls the other switch, allowing Bennett and Miles to disconnect seven cars containing the Folgers, aside from LJ, Grey, the Jackboot army, and the prisoners. After the train is reconnected, Layton confronts Melanie, realizing that she knew he'd have to cut the prisoners loose. Melanie confirms it, stating that she knew he'd have to make the choice and that these are the decisions that they have to live with every day. Melanie then declares that ''Snowpiercer'' is Layton's.<ref name="Blood" />
