History NightmareFuel / TheFlash2014

* Cicadas introduction is noticeably frightening and is similar to the introduction of Prometheus as while Gridlock is being transported to prison a dagger resembling The Flash logo is thrown into the street and a electrical surge causes the truck to stop. We then here the guards outside being dealt with as Gridlock (who is being restrained) listens. Then Cicada walks towards him with the dagger in hand and the show ends. One can only wonder what he did to him.

* The DeletedScene of Cicada is frghtening because of his VaderBreath.

* In the stinger, Caitlin see's that Zoom's assembled an army of evil Meta-Humans.

* The leader of Zoom's army is Black Siren... aka the Earth-2 version of Laurel Lance. So not only is the version we know dead but her doppelganger is a ruthless killer.

* In the final minutes Barry races back to the night of Nora's death once again, except this time, he does save his mother. Doing so has practically erased everything that has happened over the past 2 seasons and left his future in who knows what kinds of disarray!

** Worse still, ''they exist on other universes''. They came to Krypton, killing and performing experiments before either leaving or being driven off.

* Starts out with a literal case of Nightmare Fuel, as Savitar's horrifying visage is presented up close and in the camera, aka. Barry's minds eyes, causing him to pull a CatapultNightmare.

* Despite just doing her job, and becoming a FriendlyEnemy to Cisco, Gypsy breaking into STAR Labs and shooting H.R. point blank is unsettling.

* Killer Frost briefly takes over Caitlin when she tries to stop Iris's infection from spreading. She sounds both angry and smug when she says that she could freeze Iris to death if she carried on.

* Wally being absorbed into the Speedforce. He's ''begging'' for help before he vanishes.

* Crossing with {{Tearjerker}}, Iris's death caused the demise of Team Flash: Barry becomes a recluse, Joe crawls into a bottle, Wally is left physically and emotionally broken, Cisco lost his hands, and Julian is the caretaker of a incarcerated Killer Frost.

* Partway through the episode, The Flash runs into Star Labs, yanks off his mask, and breathlessly asks where Iris is. As soon as HR tells him, Savitar turns his head to the side, showing off his disfigured face to the team.

* Amunet carries a bucket of metal around which she uses to form a deadly gauntlet then fling the metal pieces with nasty accuracy...as a pair of cops learn the hard way.

* Up until this point Ralph has been a SmugSuper, and not without reason, as his powers protect him from just about anything. Along comes Axel with a water gun that shoots pink slime...that proceeds to eat through Ralph's costume and skin. No wonder he panicked.

* The Ax-Id itself is pretty awful: pink acid that eats through the victims skin and melts them to death. According to Harry, it has a pH level of -50 and he had never seen anything like it. The shots of Ralph's burnt leg are horrific.

** The way that early "burst" of energy seems to grow larger as the milli-second ticks away is downright freaky.

* [=DeVoe=] casually uses Null's power to stop the truck carrying Fallout, not only dose this prove [[DroppedABridgeOnHer she suffered the same fate as the other bus meta's]] but our hero's never even stop to react they're so used to [=DeVoe=] killing people they tried to save they're not even reacting to it anymore.

* [=DeVoe=] tries to strangle Cecille, who is ''still in the process of giving birth''.

* When Barry goes berserk, his eyes glow red and his face starts to vibrate just like the Reverse-Flash. And, going by the comics [[spoiler: he might actually ''be'' the Reverse-Flash!]]

* Savitar was apparently such a potent source of in-universe NightmareFuel that [[spoiler:Cisco installed a self-destruct system into the new suit. And Barry is almost killed by it when Kilgore hijacks his suit.]]

* The Thinker [[spoiler: hasn't just pulled a GrandTheftMe on Dominic; he's used his old, dead body to frame Barry.]]

* Barry's act of [[spoiler:freeing Big Sir]] winds up getting him in trouble with the Warden [[spoiler:who noticed him speeding Big Sir out, and realized he's the Flash... and then had him drugged and moved to an isolated cell. The last shot of the episode sees him call up Amunet to sell him to her]].

* Just when you thought the Thinker couldn't get any worse, he [[spoiler: puts his mind into Hazard, effectively killing this potentially heroic woman, just to add her power to his own and give him another face to hide behind.]]
* And ''then'', [[spoiler: Thinker/Hazard uses Weeper's tears to drug his wife so she'll be perfectly fine with this new body. In short, it's now clear that whatever love [=DeVoe=] had for her is long gone, he only sees her as another tool for his ultimate plans and no longer cares of her feelings regarding his body hopping.]]

* Marlize trying to make a video to remind herself [=DeVoe=] has been [[spoiler:drugging]] and lying to her. [[spoiler: Turns out [=DeVoe=] knows about it. Turns out she did it before. Turns out he's been wiping Marlize's memory, over and over.]]
* The final scene implied that [[spoiler: Harry was Eobard Thawne.]] Even if that doesn't turn out to be the case, there is still the implication that Harry is--much like [=DeVoe=]--gradually veering into darker territory with use of the Thinking Cap, [[ProperlyParanoid just as Cisco feared]].

* Mixed with TearJerker, [=DeVoe=] [[spoiler:taking Ralph's body while Barry's paralyzed and ForcedToWatch.]]

* [=DeVoe=] casually uses [[spoiler:Null's power]] to stop the truck carrying Fallout, not only dose this prove [[spoiler:[[DroppedABridgeOnHer she suffered the same fate as the other bus meta's]]]] but our hero's never even stop to react [[spoiler: they're so used to [=DeVoe=] killing people they tried to save they're not even reacting to it anymore.]]

* [=DeVoe=]'s endgame is finally revealed: [[spoiler:reducing all other human beings into vegetables by taking away their intelligence.]] It also raises the disturbing possibility that he ''isn't'' DrunkOnPower; he may have ''always'' wanted a world that he [[spoiler: wouldn't have to share with other sentient beings.]]
-->'''[=DeVoe=]''': [[spoiler:I will be all that remains.]]

* Just when it looks like the Enlightenment is foiled, [[spoiler: [=DeVoe=] steals a satellite from S.T.A.R. Labs.]]

* What does [[SoreLoser [=DeVoe=]]] do when his plan is truly and completely foiled? [[spoiler: He sets up the S.T.A.R. Labs satellite to crash into Central City, which would cause an extinction-level event. He really has reached the point where he would rather kill off all humanity rather than let it exist without his rule.]]

** Even moreso, Joe mentions beforehand [[WhyDidItHaveToBeSnakes that he finds ordinary gorillas scary enough]]. Then when he meets Grodd, he's taken, separated from the others and MindRape{{d}}. No wonder he's in tears. The normal animals intimidate him; Grodd is a gigantic, vengeful, murderous and ''psychic'' example of the creatures that already make him nervous.

* Before either of these, the way [=DeVoe=] utterly ''massacres'' the ARGUS agents.\\
It starts with him crushing the throats of those at the front gates.\\
Then he shrinks the first person we see him encounter inside the building, and ''steps on him''.\\
[=DeVoe=] then gets shot a bunch by the man's comrades- but Ralph's powers let him absorb the bullets and re-direct them, resulting in a fairly gory (by Flash standards) demise for those specific agents.\\
Then he uses Izzy and Null's powers to curb-stomp most of the other agents, before finally using Black Bison's powers to ''reanimate their corpses'', because he can't be bothered to fight the remaining soldiers himself.\\
In the end, only a single man is left standing. [=DeVoe=] takes him out with a marble... and a little '''luck'''.

* The final scene raises the incredibly disturbing possibility that [[spoiler: "Harry" may actually be Eobard Thawne following the events of ''Series/CrisisOnEarthX''.]]
** Even if that doesn't turn out to be the case, there is still the implication that Harry is--much like [=DeVoe=]--gradually veering into darker territory with use of the Thinking Cap, [[ProperlyParanoid just as Cisco feared]].

* The leader of Zoom's army is Black Siren...aka the Earth-2 version of Laurel Lance. So not only is the version we know dead but her doppelganger is a ruthless killer.

** The worst part is that the moment they show up, Zoom goes from a SmugSuper to ''[[VillainousBreakdown screaming in terror]]''...and the ''sound'' stops midway through while he's clearly still screaming, implying the RapidAging the Wraiths are inflicting on him has [[AndIMustScream robbed him of the ability to physically scream no matter how much he wants to.]]

** Even if that doesn't turn out to be the case, there is still the implication that Harry is--much like [=DeVoe=]--gradually veering into darker territory with use of the Thinking Cap as, [[ProperlyParanoid just as Cisco feared]].

* Just when you thought the Thinker couldn't get any worse, he [[spoiler: puts his mind into Hazard, effectively killing this otherwise bright woman, just to add her power to his own and give him another face to hide behind.]]
* And ''then'', [[spoiler: Thinker/Hazard uses the blue tears to drug his wife so she'll be perfectly fine with this new body. In short, it's now clear that whatever love [=DeVoe=] had for her is long gone, he only sees her as another tool for his ultimate plans and no longer cares of her feelings regarding his body hopping.]]

* Marlize trying to make a video to remind herself [=DeVoe=] is manipulating her. [[spoiler: Turns out [=DeVoe=] knows about it. Turns out she did it before. Turns out he's been wiping Marlize's memory, over and over.]]

* Marlize trying to make a video to remind herself [=DeVoe=] is manipulating her. [[spoiler: Turns out [=DeVoe=] knows about it.]]

** While it's clear from the start that he's up to no good, seeing the friendly and soft-spoken Harrison Wells/Thawne murder a civilian out of nowhere without breaking a sweat is chilling to say the least.
