Editing Melanie Cavill (section)

===Difficult decisions and choices ===
Melanie is faced with a difficult decision when [[Javier De La Torre|Javi]] reveals that they are unlikely to pass through the upcoming glacial collapse without damage. Javi recommends that they scale back the power by 12%, however, Melanie cites that they cannot afford any blackouts — especially with the current concerns of the passengers — and that they should push ahead.

Later, Melanie realizes that this was the wrong decision when the cliff collapses and one of the Ag-Sec carriages is damaged, freezing everything inside. Melanie agrees to scale back 12% whilst the damage is fixed. Later, amidst concerns by Jinju and Bennett, Melanie decides that water and other essentials will be rationed per class; Bennett remarks that this is killing the passengers from the tail up.<ref name="brace">''[[Prepare to Brace]]''</ref>

Melanie is faced with a further difficult decision when Layton begins to find out details surrounding Sean's death. Layton refuses to reveal any of the information unless he is allowed to visit [[Josie Wellstead]] in the Tail. Eventually, Melanie reluctantly agrees but is oblivious to the fact that Layton is exchanging details about the Train's security with Josie.<ref>''[[Access Is Power]]''</ref>

After Niiki is murdered, Melanie faces anger and suspicion as she helps Layton look into the first-class passengers. Though Layton suspects first class will prevent any of their own from facing justice and expresses outrage at the luxuries they enjoy, Melanie assures him that she is on his side, revealing her own humble origins. Melanie orders Layton to be first-class' "worst nightmare from the Tail" while she will help clear the way for him. As they work together, Layton notices Melanie's level of power and becomes suspicious of her true identity.

After [[Erik]] is identified as the killer, Melanie, acting as Layton's partner due to [[Bess Till]] being busy chasing Erik, interrogates the Folger parents as Layton interrogates [[LJ Folger]]. After Erik is killed by the [[Jackboots]], Layton signals to Melanie that LJ is responsible and she has [[Jackboots]] brought in who arrest LJ after a struggle when Layton announces her guilt. Melanie makes a train-wide announcement that the killer is dead and that the second suspect has been arrested before bringing Layton for a drink. By now, Melanie has realized that Layton knows who she really is which he confirms, stating that "a myth is a powerful thing." Melanie is revealed to have drugged Layton, apologizing to him and stating that she hopes that he never knows the weight that comes with being a myth. Melanie has Layton secretly put into the Drawers, keeping it off-the-books so that no one else knows about it. However, Melanie, not wanting Layton to get hurt, orders that Layton is not to be damaged.<ref name="WTM">''[[Without Their Maker]]''</ref>
