Editing Into the White (section)

==Plot==
Having been confined to a small cell by [[Joseph Wilford|Wilford]] for her outbursts at dinner the previous night, [[Alexandra Cavill|Alex]] thinks about her perspective on Melanie and the way things are done on Snowpiercer. Alex finally realises that Melanie's way — albeit complex and wild — is the right way to run the trains as opposed to Wilford's totalitarian rule; with this, she finally aligns herself with the rebels and more notably, [[Andre Layton]]. Her thought process is quickly interrupted, however, with the arrival of Mr. Wilford who wishes Alex to apologise and come back to his side before being freed from the cell. Alex is quick to rebuke him, however.

In Compost, [[Andre Layton|Layton]] and [[Ruth Wardell|Ruth]] plan their escape following the message from Big Alice's Engine. Layton tells Ruth that the escape must happen later that night and asks if she is in for the whole stretch; Ruth remarks that for Snowpiercer and Melanie, they will do what needs to be done. With this, the two kill the guard shortly after their food is delivered and free themselves from Compost. Wandering up-train, they stumble across Alex in her cell and explain that Melanie is alive and well and that they must steal control of Big Alice in order to collect her. Alex informs them that the Engine and Wilford's room are connected by a secret tunnel, but further informs them that they are approaching the Rocky Mountain test track shortly therefore will need both Engine's to succeed. Alex refuses allowing them to break her out, however, citing that she can manipulate Wilford and Kevin into freeing her. 

Wilford becomes increasingly annoyed at [[Miss Audrey|Audrey]] due to her oversleeping after a heavy night of drinking. Things become increasingly more violent when Kevin tells Wilford that [[Zarah Ferami|Zarah]] is reluctant to eat but he would happily "slap her". With this, Wilford hits Kevin and the latter is informed that pregnancy comes with protection aboard Snowpiercer.

Breaking into the Engine, [[Ruth Wardell|Ruth]] and Layton kill the two Jackboots protecting and watching [[Javier De La Torre|Javi]]. They tell Javi that they must collect Melanie as planned, but he tells them that he needs a minute to think.

[[Josie Wellstead|Josie]] talks with another fellow amputee in the Headwoods' lab as the two try on prosthetic hands. Josie explains how she felt during her exposure to the cold but that ever since the Headwoods healed her she wants to go outside to see what she can do; she makes no effort to deny that she is the new "[[Icy Bob]]". 

Having manipulated [[Kevin McMahon|Kevin]] into securing her an audience with Wilford, Alex apologises to Wilford on the grounds that she now realises that [[Melanie Cavill|Melanie]] was wrong and it was a fools errand sending her out into the Freeze. Furthermore, she remarks that she now sees that she belongs with Wilford, and promises to apologise to all those she offended. On her exit from Wilford, however, she informs [[Bess Till|Till]] that they're seizing the Engines and Layton is back. 

Back in Big Alice's Engine, Javi remarks that it will be difficult to communicate with [[Bennett Knox|Bennett]] given [[Sykes]] is watching him all of the time. Nonetheless, Javi communicates a message to Bennett in code, roughly pertaining to a rail-line switch further up course. Bennett remarks that he has understood the message, and Javi sends Layton and Ruth up-train. 

Layton and Ruth are passed through the border of the train under the guise of carnival equipment for the new carriage. When they emerge, they detail the plan to [[Lights]] and [[Bojan Boscovic|Boscovic]]. Boscovic laughs at the fact that he is working with the Tailies, but is on board with the plan nonetheless. 

With [[Snowpiercer]] quickly approaching the Rocky Mountain test track, Bennett realises that he must distract [[Sykes]] long enough for Javi to make the switch of the tracks. A fight erupts and Bennett is badly beaten, but with the turbulence created by the switching of lines, Bennett is able to get the upper hand and Snowpiercer successfully switches tracks from the mainline to the [[Rocky Mountain Test Track]]. Despite the success in switching the tracks, Sykes remarks that Wilford will feel the differences in the tracks and the restlessness of the test track. Bennett tells Javi that they must hold on a little longer, and that he is a fantastic engineer. 

Wilford quickly becomes suspicious of the movement of the trains, but Alex tries to distract him and calls forward to the Engine. Talking with Bennett, she is informed that they have switched tracks, but she must keep Wilford busy. Alex is unable to do so and, when Wilford looks through the window, he realises they have been played and orders both Engine's stormed. As the alarms sound, Layton talks with Bennett who is informed that they have passed the pick-up point, but Melanie is nowhere to be seen. Bennett tells him that she will be there and they will slow more when she arrives. 

Moments later, Wilford is successful in breaking into Big Alice's Engine and Javi is badly beaten. After Javi proclaims that he cannot be killed as [[Joseph Wilford|Wilford]] needs engineers, Wilford orders his dog to attack and Javi is further harmed by the dog. As Wilford takes control of Big Alice he begins to accelerate, and Bennett is quickly informed that Javi is no longer at the helm of the train. Despite Bennett's attempts to brake, Wilford is aware that he has more momentum and torque and is able to push the train over the peak and allow gravity to propel them further. As the train passes the peak, Alex is forced to watch as the train passes Melanie in the bleak snow outside.<ref>We saw the same scene from Melanie's perspective in the last few seconds of episode S2E06, [[Many Miles From Snowpiercer]].</ref> 

Following this, Alex becomes angered and slashes Wilford's neck with a razor blade she procured earlier (in a attempt to kill him); she bolts from the Engine momentarily as Wilford is taken to the Headwoods' lab and stitched up. Wilford orders the train searched and that [[Josie Wellstead|Josie]] be sent outside to breach the Engine. Despite the Headwoods remarks that she isn't ready, Wilford orders her sent anyways.

Meanwhile, Alex has joined up with Ruth, Andre, and Boki, and the four plan to turn back for Melanie. Boki explains that the aquarium car can be manually unlocked, giving them a 10-cart [[Pirate Train]] to turn back and rescue Melanie. Ruth is unsure of the plan given the technicalities and dangers of leaving the train in Wilford's hands, but she is eventually convinced. Whilst Till is further easily convinced, Zarah refuses to go with Layton and explains that the baby will afford her great protection. 

As the plan sets in motion, Josie is sent out onto the top of the train, an event that quickly triggers an alert in Snowpiercer's Engine. When Bennett realizes that it is Josie that has been sent outside, he finds himself with another tool in his toolbox to use to his advantage. 

Layton begins to set his plan in motion down-train and explains to Wilford that he must not harm Zarah or the others whilst he is gone. Layton takes [[Miss Audrey]] as hostage in an effort to convince Wilford. Whilst Wilford is not convinced that Layton will not harm Audrey, things begin to go south when Boki is ambushed by Wilford's men and cannot uncouple the J-Link. Unbeknownst to Wilford, however, Josie remains loyal to Layton and breaches the aquarium car, destroying it completely. Having been delayed by Kevin, Ruth is inadvertently left behind and can only watch through ''Snowpiercer's'' windows as the [[Pirate Train]] leaves without her.

As the new Pirate Train stops outside [[Breslauer Weather Station]], Layton and Alex are saddened to see that [[Melanie Cavill|Melanie]] has used the remainder of the power to keep the data drives warm, but she is nowhere to be seen. Alex finds a handwritten note from Melanie detailing that she realized she could no longer survive but needed to preserve the drives; Melanie is at peace with her decision and hopes her sacrifice will fuel a better world. 

Analyzing the data aboard the Pirate Train, Bennett, Till, Layton and Josie are surprised to find that Melanie was successful and there are several points in the world where warming is occurring. With this, the four set off in the Pirate Train to reclaim Snowpiercer from Wilford.
