History NightmareFuel / Snowpiercer

* In flashbacks, we see why Melanie chose to abandon Wilford -- in the last chaotic moments before Snowpiercer launched, Wilford ordered the slaughter of a number of her scientists in order to make more room for his jackboots.

* Franco the Elder's RoaringRampageOfRevenge. This MookLieutenant gets pretty terrifying after Yona kills his brother. He fires indiscriminately through the windows of the train and at front-section survivors trying to get at Yona. This is taken UpToEleven in the sauna scene, where Franco executes one of his own men for questioning his killing of a front-section passenger (and would have done the same to another had he not run out of ammo). He then takes on Curtis and his team by himself, and proves himself quite the HeroKiller when he's able to shrug off every wound they inflict on him, beat Curtis into unconsciousness, easily subdue and shoot Tanya, and overpower and kill Grey. It's unsettling to see him stand triumphantly over these BadassNormal characters, calmly smiling and trying to fix his messy hair.

* Just the concept of [[AdultFear children being taken away from their parents]] and becoming parts in an engine that never stops, like they were just bits of machinery and not actual human beings.

** The hope of the chemical ending global warming giving way to despair when this new ice age hits.

** The brutal, bloody race by people to get on board the train with horrible fighting, mass chaos, nothing but people at their most desperate dong anything to survive.
** The train finally taking off and smashing into the now-frozen bodies of people, breaking them like...well, ice.
* Near the beginning, Mason gives a laborious speech to the tail section, the gist of which is "I am a hat, you are a shoe", while Andrew's arm is hung outside of the train to be frozen and then smashed off with a massive hammer. In case you were wondering [[CrapsackWorld what kind of world this is]], Andrew's crime was [[DisproportionateRetribution throwing a shoe at Claude, a front-section passenger]]. And the only reason he threw his shoe at Claude in the first place is because [[PapaWolf she took his son, Andy, away from him]].
* Paul's existence in the kitchen. Both Curtis and Edgar note that Paul looks and acts very different from how he used to be before he was taken from the tail section.
* After getting to the kitchen car, Curtis finds out what the "protein bars" are made out of: ground-up insects. [[IAteWhat After throwing up in his mouth a little bit]], he quickly decides it'd be better not to tell the rest of his people, likely to prevent a massive freak out that could break the revolt he's started. What's even worse is that right before this, everyone had gotten excited about having unlimited access to their only source of food and [[{{Squick}} started chowing them down]].
** Especially nightmarish when you consider they've all been eating the shit for seventeen years, and that they were probably better off eating each other's limbs.

** Before the fighting begins, a few of the axe-men show their enemies a large fish that they proceed to bury the heads of their axes into. It is never commented on, but it's definitely a scare tactic that unnerves the tail-section fighters as well as the audience.
** The fight stops prematurely as the train is about to collide with a wall of ice on the tracks. Everyone gets down low and braces for the impact. There's a very freaky moment when Curtis looks beside him and sees one of the masked axe-men [[SlasherSmile smiling at him with bloody teeth]]. Turns into a SugarWiki/MomentOfAwesome after they've passed the ice wall and the fight continues, with Curtis immediately killing that man.
** How about when the Axe Gang puts on their night-vision goggles as the train goes into the dark tunnel. Seeing the heroes getting butchered as they stand blinded in the dark is horrifying. Meanwhile, Mason is gawking at the slaughter with a big smile on her face and her men are frantically taking count of everyone who dies.
* The classroom car. The young schoolchildren give no regard to the tail section passengers, to the point where they ''cheerfully'' tell Tanya and Andrew that their sons were crying after they were taken, and their pregnant teacher sings a song with them that glorifies Wilford and the "sacred Engine."

** The pregnant teacher pulls out a gun from her basket of eggs and repeatedly shoots at the heroes, successfully killing Andrew by [[BoomHeadshot shooting him through his head]]. Turns into a SugarWiki/MomentOfAwesome when Grey avenges Andrew by throwing a knife at her neck, killing her almost instantly.
* Franco the Elder's RoaringRampageOfRevenge. This MookLieutenant gets pretty terrifying after Yona kills his brother. He fires indiscriminately through the windows of the train and at front-section survivors trying to shoot Yona. This is taken UpToEleven in the sauna scene, where Franco executes one of his own men for questioning his killing of a front-section passenger (and would have done the same to another had he not run of ammo). He then takes on Curtis and his team by himself and proves himself quite the HeroKiller when he's able to shrug off every wound they inflict on him, beat Curtis into unconsciousness, easily subdue and shoot Tanya, and overpower and kill Grey. It's unsettling to see him stand triumphantly over these BadassNormal characters, calmly smiling and trying to fix his messy hair.
** Franco's absolutely insane SlasherSmile after Curtis shoves a knife into him. Considering this character had been TheStoic thus far, it's quite freaky.

* The first months of being a Tail Section passenger. Everyone cutting off their limbs to feed others, killing children and the weak to sustain themselves. While there are people who are eating steak and getting their suits tailored cars away.
* [[DissonantSerenity The Egghead smiling pleasantly]] as he cuts down screaming tail-section passengers with a submachine gun.

* Realizing that Gilliam did and endured all of that as part of a plan to intentionally cull excess members of humanity, [[DystopiaJustifiesTheMeans and no other reason]].
* When the garish, spoiled, tweaked out front-section masses converge on the engine antechamber, trying to kill Curtis, Minsoo, and Yona.
* Yona tries to get the matches from Curtis so that Minsoo can blow up the door to the outside, by using the Kronole as the explosive. However, thanks to Wilford nearly convincing Curtis to take his place and lead the train, Curtis ''pushes Yona away'' and glares at her. Just a few scenes after he adamantly refused to take over Wilford's place, Curtis' change in attitude due to Wilford's manipulation is frightening to both Yona and the audience.
* Yona suddenly senses something below her, and she scratches the floor tiles to uncover Tanya's son, Timmy, beneath the floor.
* The way Andy moves to his 'post' and does not respond to Curtis, who's pleading for him to stop operating the Engine. In merely ''a few days'' since he and Timmy were taken, young Andy has become BrainwashedAndCrazy thanks to Wilford.

* Melanie casually reminding Layton that the strawberry plants on the train are more important than the human lives of those in the Tail.

* Just the cold way Ruth converses with the mother of a child, offering herself up in place of her daughter's punishment.

'''Ruth:''' Yea, a little girl who helped to kill six men.\\

* First Class passengers hear about the murder in Third Class, and former lawyer Mrs. Folger offers her insight in exchange for more information.

* Layton has to tell Till and Pelton that the rumours about cannibalism in the Tail was actually true. He was in a group that killed the cannibal leader, and they ate a piece of his heart so none of them could claim innocence.
* Not just how easy it was for people to lose their limbs, the series show just how unforgiving temperatures are when an avalanche slams into the train. When the cattle car's window breaks, it takes ''seconds'' for the herd to expire, and the head butcher is frozen so quickly that when the thermal-suited engineers investigate, his corpse is still standing upright.

* A bloody fight, then an equally bloody riot, breaks out while First Class passengers watch the whole thing from above, laughing.
* The killer brutally murdering others before making his way to Nikki, who is still recovering from the drawers. The way he stares back at Nikki, and his sheer brutality in how he disposes of his victims is spine chilling.

* Jinju skinning the fish for a beautiful sushi meal is cut with the bloody scene of Nikki’s murder
* Osweiller rightfully points out the horror that is two unarmed Brakeman going after a man skilled in using firearms. Sure enough, the presence of the gun frightens the passengers, who haven’t seen one since boarding the train.

* The steadfast belief of the train, summed up nicely by Ruth: “We don’t have will, we have order”.

[[AC:6 - Trouble Comes Sideways]]

[[AC:8 - These Are His Revolutions]]
[[AC:9 - The Train Demanded Blood]]

* One of Snowpiercer's supply trains, the ''Big Alice'' survived. It latches on Snowpiercer and immobilizes it. The train bears Wilford's symbol, implying he managed to survive the world's freezing and now has his own train.

* Wilford is alive, and he's furious at Melanie due to her betrayal. Now he wants the Snowpiercer back, or he will decouple the Big Alice and leave everyone inside to die, as the Snowpiercer no longer has enough power to move on its own. If it wasn't for the fact Melanie placed an explosive in the decoupling system, Alex would've doomed everyone to die, and her mother would've been forced to compost every last corpse inside as punishment.
* One of Wilford's men is Icy Bob, a tall and muscular man with a bald head and his body covered in scars. It's uncertain if he's fully human anymore, as he single-handedly repels Layton's attack, and doesn't react at all to the influx of freezing air used to repel the Tallies. He's so strong he kills a man with a single blow.

* Lights, one of the Tallies, is ambushed by Wilford supporters and has [[{{Fingore}} two of her fingers cut off]].

* The titular trade - back before the Freeze, Miss Audrey secured her ticket by letting Mr. Wilford watch her as she opened up her wrist and bled out in a bathtub, entirely trusting that he would actually bring her back.

* Melanie spends a month inside a freezing station where the food is nearly non-existent, there are dead bodies in the snow, and there's an arm in the refrigerator. And all the while, she's being tormented by hallucinations of Wilford, taunting her that she'll never survive.
* In flashbacks, we see why Melanie chose to abandon Wilford - in the last chaotic moments before Snowpiercer launched, Wilford ordered the slaughter of a number of her scientists in order to make more room for his Jackboots.

** Alex and Ben finding the bodies is particularly grim. Every single one is bundled up in their bunks, fully clothed - obviously trying to escape the terrible cold as the cars progressively froze.
** There's also the fact Wilford knowingly split up families and loved ones before it happened. Many of the survivors must have lived with the fact their loved ones were saved from the Freeze only to be murdered by a sociopath for being deemed useless. It's no wonder than Big Alice's crew seem so demoralised and hopeless in season 2 when we see them.

* In the final scene of the season, Melanie is driving Snowpiercer along a track and sees a massive explosion in the distance, with what looks like a train car being tossed into the air. And whatever this is, Snowpiercer is headed right towards it.

* The ending of the Escape - wherein the ''entire'' train is ''dead'' - except for one.
** This especially became worse during the Covid19 pandemic.
* There can be something unsettling about seeing people in a perfectly functioning (albeit corrupt, and ''very'' exploitative) society worshiping the engine itself as a God.

** Finally, the room Wilford takes Alex from just before the cars separate is clearly a designated children's room. Given that Alex is the youngest on Big Alice, the awful implication is that Wilford killed nearly every child on Big Alice to ensure his own survival.

* In the final scene of the season, Ben is driving Snowpiercer along a track and sees a massive explosion in the distance, with what looks like a train car being tossed into the air. And whatever this is, Snowpiercer is headed right towards it.

* Virtually everything we see of Wilford's cull. Of it wasn't established he's the series' biggest monster, it certainly is now.

* We see what actually happened when Wilford culled Big Alice; after checking the crew for intellect, physical and mental prowess, he simply detached three cars worth of people, letting them freeze in their sleep.
