Editing Melanie Cavill (section)

===Identity Crisis===
Following the revelation that [[LJ Folger]] is partly responsible for Sean Wise's murder (and the first murder), Melanie convenes a tribunal to decide her fate. Things become difficult, however, when Third — specifically [[Miss Audrey]] and the Nightcar — begins causing trouble due to lack of representation on the tribunal. When Melanie confronts Audrey, the latter threatens Melanie, remarking that Third touches most of the train and will be heard one way or another.

Melanie heeds the warning and reselects the tribunal with one representative from each class — the Tail is not represented as they are not considered passengers. This move is not popular in First and Second and, when she LJ is found guilty — and reveals that Sean Wise was a Wilford Informant — she commutes her sentence as she fears LJ may be aware of her identity as the mysterious Mr. Wilford. Before reuniting LJ with her parents, she talks with her, and LJ promises to keep "Mr. Wilford's" secret as a thank you for commuting her sentence.<ref>''[[Justice Never Boarded]]''</ref>

Melanie's situation is later amplified when [[Andre Layton]] is rescued from the Drawers by his girlfriend, [[Josie Wellstead]], and comes after Melanie. He holds her at knifepoint whilst she is trying to fix the hydraulic system on [[Snowpiercer]] and tells her that he knows the drawers are experimental and not working properly. Melanie tells him that he has it wrong and that the drawers are a lifeboat, containing the very best part of humanity in an effort to save them from the freeze. Melanie warns Layton that the social order on ''Snowpiercer'' relies on the myth of Mr. Wilford, and that the society would collapse should her secret be revealed; Layton reluctantly allows her to leave to fix the hydraulics with the train in danger of derailment. With seconds to spare, Melanie saves the train. She later gifts [[Miles]] a caliper given to Melanie by Mr. Wilford himself and tells the boy that Mr. Wilford needs something from him.<ref>''[[Trouble Comes Sideways]]''</ref>
