'Snowpiercer' Season 1 Finale Preview: Revolution has won but how long can it last before things fall apart?

TNT's 'Snowpiercer' Season 1 is drawing up to its finale. Last stop, Episode 10 '994 Cars', where Andre Layton (Daveed Diggs) and Melanie Cavill (Jennifer Connelly) will have to deal with the consequences of their actions.

In Episode 9 'Old Ways, Old Wars', Layton was forced to make a terrible choice, sacrificing lives to win the war. The revolution has now succeeded but Layton is more traumatized than ever and he has the unenviable task of getting Snowpiercer back on track.

If history has taught us anything, it's that revolutions don't always succeed in fulfilling the idealistic aspirations that drive them. Layton now has control of the train but will he be able to deliver the justice he promised? That remains to be seen.

He also has to decide what to do with the people who stood against the revolution, mainly the passengers in First Class whose lavish lifestyle has now been jeopardized. If he chooses to show them mercy, there's a pretty good chance they will stir up trouble before long but considering the blood on his hands already, Layton is bound to be hesitant to cause more violence.

Meanwhile, Melanie may have helped the revolutionaries but that doesn't necessarily mean they will let her live. At the bare minimum, she will probably be consigned to the engine where she will have to keep the train running without the comfort of mingling with the rest of the train, which would be an acceptable penance for her but the synopsis does tease trouble to come for the former head of hospitality.

Seeing as the show has already been renewed for a Season 2, we know the story won't end here. The finale will no doubt set up new conflicts to drive the next season forward and we'll just have to wait and see what's in store for us as 'Snowpiercer' enters its conclusion.

Here's the synopsis for '994 Cars': "In the revolution's aftermath, Layton (Daveed Diggs) struggles to govern the shell-shocked survivors. Melanie (Jennifer Connelly) finally makes peace with her demons, only to realize the biggest threat to their survival is right over her shoulder."

'Snowpiercer' airs Sundays at 9 pm ET on TNT.
