Editing Melanie Cavill (section)

===Going Separate Ways===
Melanie and Layton subsequently make a joint announcement to the trains, offering everyone a choice: stay on ''[[Snowpiercer]]'' under Melanie or leave on ''[[Big Alice]]'' for New Eden. Melanie promises to no longer lead by fear but through science and truth. As everyone makes their choice, Bennett predicts that the train has a decade or two at most left and agrees to join Melanie when she promises to give him her all. However, Alex decides to go on ''Big Alice'' with Layton and the two say a tearful goodbye, Melanie leaving her daughter her jacket. At the separation point in Ag-Sec, Melanie and Layton share a warm goodbye, with Melanie promising to look after [[Miles]] for him while Layton looks after Alex for her. Later, in the Engine, Miles notices an increase in power which Melanie explains is because of the loss of weight from the departure of ''Big Alice''. Melanie asks if they can still see the other train, but Bennett tells her that they can't and ''Big Alice'' is hitting some weather.

Three months later, Melanie sits alone in ''Snowpiercer's'' Engine when she suddenly notices something shoot into the sky and explode, concerning her.<ref name="Sinners" />
