Editing Javier De La Torre (section)

===[[Melanie Cavill]]===
Though good at his job, Javi is often seen questioning Melanie's decisions. Javi implies that he feels he has no choice but to follow Melanie's orders as he is not sleeping with her unlike [[Bennett Knox]], thus not affording him a level of protection.

When First rebels, Javi abandons the Engine and betrays Melanie, revealing her actions to the Folgers, [[Ruth Wardell]] and the Jackboots. However, while Javi sides with First, their tactics appear to be too much for him as he later helps [[Jinju Seong]] rescue Melanie from execution.

Following [[Andre Layton]]'s takeover of the train, he and Melanie work together again in the Engine, Melanie having apparently given up all other duties to be an Engineer full time. After Melanie declares that its snowing while trying to break Mr. Wilford's uplink from ''[[Big Alice]]'', Javi simply believes that she's hallucinating due to the cold and expresses concern over her well-being.

When Melanie returns and steals the train once again, Javi helps her out of betrayal and anger, even joking that at least he wasn't in the bathroom this time and could actually help her do it. Although Javi supports Melanie, he ultimately chooses to join Layton in going to New Eden rather than remaining on ''Snowpiercer''.
