Editing Melanie Cavill (section)

===Hiring Layton===
Melanie is the voice of the train aboard [[Snowpiercer]], and also the head of hospitality. She receives numerous complaints from passengers that they have heard of uprisings on the train. Melanie sends [[Ruth Wardell]] to remove [[Andre Layton]] from the Tail in a bid to help with the investigations into the murder that has caused the widespread panic; it is revealed that Layton was a homicide detective before Snowpiercer departed.

Layton enters numerous negotiations with Melanie, outlining his terms for working the murder case — third-class immigration and rations for the Tailies. Melanie refuses each of his demands, however, remarking that it would do him well to help catch the murderer; she gives him a chance to escape the Tail of the train. Layton is told that if he can clear Nikki's name and solve the case they will make him Train Detective and move him to Third Class, he refuses, however, citing that he wants his demands met.

After the revolt of the Tailies, Melanie enlists Layton to calm them. When he is successful, Ruth reveals that Wilford will demand six of the Tailies lives in exchange for the security guards lost. Layton pleads with Melanie, agreeing to work for her and solve the murder if she spares the lives of his friends; she reluctantly agrees. She later returns to the front of the train where she takes over as driver, and it is revealed that she is in fact the mysterious Mr. Wilford.<ref name="ftwc" />

The following day, Melanie is surprised to see Layton has been beaten up after causing a scene with the guards. She becomes increasingly angry and remarks that he is only in his position because "Mr. Wilford" needs him to solve the murder. She is impressed, however, when Layton figures out that Sean — the recent murder victim — was an informant for Wilford, hence why "he" wants the case solved to figure out what secrets were spilled.<ref name="brace">''[[Prepare to Brace]]''</ref>
