History NightmareFuel / GravityFalls

** Want a little more ParanoiaFuel? Pay close attention to the pictures of Bill on the journal page Gideon uses to summon him. It's at 0:10 seconds of [[https://www.youtube.com/watch?v=TvWFY6mJpWA&feature=youtu.be&t=1m this video]]. There's a picture of the triangle symbol that's on every dollar bill in America, with the caption "HE'S IN MY WALLET!" That's right. Do you have bills on you? Then you ''literally'' [[{{Pun}} have Bills on you]] - he can see you through all of them.

* Mabel's situation with Gideon, in general, is creepy in a more grounded way than many of the show's creepy elements. Gideon's magic amulet and journal filled with information on the supernatural might be fantastical... but being pursued by a jealous, clearly unstable individual who won't take "no" for an answer and uses tools such as guilt-tripping to keep someone who's clearly very uncomfortable in a relationship with them--and who even turns outright violent when faced with her rejection, [[MurderTheHypotenuse albeit towards Dipper]] - is a ''very'' realistic kind of unsettling.

---> "INCREASING MY POWER IS EASY AND ANYONE CAN DO IT! JUST DRAW MY FORM ANYWHERE IN YOUR HUMAN WORLD - EACH IMAGE OF ME ACTS AS A PEEPHOLE FROM MY DIMENSION TO YOURS, THE MORE I SEE, THE MORE I KNOW. THE MORE I KNOW, THE GREATER MY POWER. THE GREATER MY POWER, THE MORE ENEMIES OF YOURS I CAN CRUSH. JUST SHAKE MY HAND"

** ''Especially'' the way onlookers and townspeople in the episode d'aw at how cute it is that [[VillainWithGoodPublicity Li'l Gideon]] has a girlfriend, with their adoration of him making them ''completely'' gloss over Mabel's potential feelings about the situation. The way so many people around her - even Stan (albeit purely for business reasons) - [[ShipperOnDeck are voicing their support for the relationship]] and heaping pressure on the poor girl to be with someone she doesn't want to be is an uncomfortably real kind of scenario, one a lot of teenage and adult viewers will know the feeling of... and Mabel is ''twelve''!

** The (real-life) third journal also gives us the reason ''why'' the page is bloodstained - Ford's prolonged bouts of letting Bill possess his body [[EyeScream started causing his eyes to bleed]].

---> '''Gideon:''' Ah- ahhhh! You're insane!

* Stan had Journal 1 ''the entire time''. He always knew about the secrets of Gravity Falls and had been secretly searching for Dipper and Gideon's journals for years. He stealthily stole Gideon's journal when the little brat was arrested, and Dipper unknowingly just handed Journal 3 to him while confessing about how he found it at the start of the summer. Remember the cipher from episode 1- ''STAN IS NOT WHAT HE SEEMS''.

** Franz in particular, as performed by Creator/PattonOswalt, is just so [[DissonantSerenity cheerfully cold-blooded]] in everything he says, and - unlike many of the other villains - [[BlueAndOrangeMorality barely seems to understand he's even doing anything wrong]].
* There is a bit of existential horror at the thought that Big Henry, an obviously beloved and valued member of his community, not only ''dies on-screen'', but dies for a ''sticker''- one that they ''didn't even win''. And on top of that, no one outside his tiny community ''will ever even know he existed''.

* Remember Stan's tattoo? The one he claimed didn't exist despite the obvious evidence to the contrary? Well, as it turns out, he actually ''isn't'' lying, because that ''isn't'' a tattoo- It's a ''scar''. A scar from a ''hot metal brand''. And during the flashback to the night his brother disappeared, they actually ''show'' him getting it- during a fight with Stanford over Journal 1, Stan claimed Ford left him behind and ruined his life. Ford, in retaliation, pushed Stan onto the side of one of the portal's controls- where the mark was - accidentally in the struggle for the Journal, all the while claiming that Stan ruined his ''own'' life. You can hear Stan's scream and see his shoulder ''steaming from the heat''. It's ''incredibly'' painful to watch.

* An easily missed tidbit: Darlene refers to herself as part of a "weird species". If there is a "species" to speak of, that means Darlene is not a singular anomaly - and she never said she was the LastOfHerKind either. '''How many more spider-creatures like her are out there right now, preying on the unwary?!'''

* The episode starts with a cute little squirrel going about its business- and then the mailbox shoots out its ''prehensile tongue and EATS IT.'' Welcome to Day 4 of Weirdmageddon, folks!

* Near the start of the episode, there are some quick shots of the characters sheltering in the Mystery Shack. Three of them - the woodpecker's husband, a unicorn, and a gnome - are partially turned to stone. The woodpecker's husband just has a stone woodpecker and a patch on his shoulder, he's clearly still able to move, part of the unicorn's neck and most of its face is a stone so maybe it can't ''eat'', and the gnome is all stone but for a waving arm. Assuming stone people aren't aware that's rather worse than being changed completely. If it was the eye bats hitting at a wrong angle they must have been rescued before the job could be finished. Or are they turning back to flesh like Lazy Susan, but more slowly?

* Bill's defeat. His last moments are of him frantically breaking down as Stanley's mind is erased - with him still inside - and offering Stan whatever he wants before his body starts to violently [[ShapeshifterSwanSong distort, glitch, and collapse on itself]]. Bill proceeds to turn black and lunge at Stan with a final cry of "'''''STANLEY!'''''" before Stan finally finishes him off. It's compounded by his petrified physical form appearing as a tombstone outside the Mystery Shack, assuring once and for all that Bill is dead.

*** As seen in "Weirdmageddon III", He has no problem with harming children and even claims he "wants to make corpses out of the twins" and was about to kill Mabel for the heck of it!

* Preston tries to ally with Bill. What does Bill do? He decides to twist Preston's face into... something... '''[[NightmareFace horrible]]'''. [[http://i.imgur.com/KD6Oi15.jpg View at your own risk.]] More specifically, Bill rearranges the functions of every orifice on his face; his mouth becomes a giant eyeball, his eyeholes become a set of ears, and both his ears become a pair of noses. To make matters worse, his muffled screaming and anguish indicate that this is '''NOT''' pleasant at all. One has to wonder how this even got past the censors.

--->Nightmarish laughter from a realm of fire, showing the dark silhouettes of countless demonic beings.

** Journal 3 states what McGucket saw too in a code. Bill claimed that he saw him removing his Exoskeleton to feed. What's scarier, that the somewhat funny-looking appearance of Bill being removable with something worse underneath, or that Bill feeds on something. What does he eat?!

---> ''"Boy, these arms are durable!"'' ''[slamming arm repeatedly in a drawer. When he removes it, it's stuck full of forks.]''

** ''Gravity Falls'' has never been one to [[NeverSayDie beat around the bush with saying 'die' or any form of the word]] but in this episode, Bill has cemented himself as [[UnderStatement a pretty bad dude]] with these jaw-droppers of lines: "I'VE GOT SOME ''CHILDREN'' I NEED TO MAKE INTO CORPSES! SEE YA REAL SOON." and "When I get my hands on you kids, I'M GONNA DISASSEMBLE YOUR MOLECULES! YOU'VE TRICKED ME FOR THE LAST TIME!"

* [[EldritchAbomination Bill Cipher]], full stop. Introduced near the end of the first season, he's described as the most powerful and dangerous being in Gravity Falls, and while a very strong target of LoveToHate among the fandom, everything about him is unsettling at best and horrifying at worst. To elaborate:
