Editing Melanie Cavill (section)

===A Chance at Recolonization===
Melanie is later traded by Wilford for [[Kevin]], but Alex smashes her snow sample. After reuniting and reminiscing with Layton, Melanie heads to the Engine where she reveals her discovery to Javi and Bennett. Melanie then explains the shocking reason that she believes that it was snowing: [[CW-7]] is breaking up in the atmosphere and falling to Earth. As a result, the planet is warming again. As Javi rushes off to make preparations, Melanie and Bennett embrace and Melanie is pleased by the chance to share the good news with the train.

Later, the three and Layton launch a probe into the upper atmosphere which confirms that the planet is warming again. Melanie tells Layton that they will need to figure out the details, but the Earth is coming back alive. However, Melanie needs access to Wilford's supplies and he will never willingly sign up for anything that he's not in charge of. Layton suggests that as their mission is hope and Wilford wants to fight that, they make him do it out in the open. Although Melanie is reluctant, she agrees and tells Layton that he needs Ruth on his side.

Layton and Melanie subsequently hold a scientific summit with Wilford in First Class dining, surprising Wilford to see them together give their history with each other. Melanie lays out her discovery for the people of both trains which Wilford's scientists agree could in fact be possible. Melanie informs the gathered crowd that they must first boot up the research station in the Rocky Mountains, but one of ''Big Alice's'' crew warns her that that route is not fit for ''Snowpiercer''. Ignoring her, Melanie states that they next need to release sounding balloons as far east as the Himalayan terminus that will send data to the research station and ''Snowpiercer'' will return in a month's time to collect it at which point they will hope to have found what they're looking for: an X on the map, a place warm enough for life to begin again. Wilford points out that the research station will have to be manned and the only person capable of doing it is Melanie herself and tauntingly states that Melanie's projects always seem to involve leaving someone behind. Wilford only agrees to help if Melanie goes herself and in turn, she demands that all hostilities cease and the trains work together which Wilford claims is what he wants. Melanie states that she will send an inventory of everything that she needs and to cheers announces that "the future is outside."

As Wilford leaves, Melanie tells Layton that Wilford is right and that it should be her. Layton states that Melanie should've told him and asks him to come back to get her. Melanie leads Wilford back to the Tail where Alex confronts her mother and demands that Melanie does not state that it's for Alex. Melanie insists that it's for everyone and that "it's hope." Alex leaves without a word, smearing her blood on the side of the door as she goes.<ref name="Smolder">''[[Smolder to Life]]''</ref>
