“You are now 21 grams lighter” is a reference to a 1907 experiment where scientists were trying to see if the soul was tangible, so they weighed people before and after death, what a fun reference haha!

[barelyhere]

No one gonna talk about why this dude just casually called himself “technically a missing person”💀

[larhyperhair]

Not to be a turbo nerd about journal 3, but they put in a funny little Retcon near the end, (Spoilers for Journal 3)
When dipper gets the Journals back after bill is defeated he writes something along the lines of:
"It seems like the Journals are in way better condition than when I found them, and this one has a bunch of pages I've never seen before! They must have been ripped out, this would have been SO MUCH EASIER if I had this info back at the beginning of summer!"
Implying of course that some of the pages WE'RE reading are missing from the In-show Journal 3

[SecondBestArtMuseum]

WOW! To think, they included genuine lore and clues in their flash games. That's WILD! And it's really funny how some of the most revealing secrets to the lore went almost completely unnoticed at large. Nobody making theories at the time EVER brought up these pieces of lore, and Old Man McGucket wasn't on anyone's radar until that fake leak.

2 hours? Nah this is pure dedication, my guy

[talkingnart]

Except you missed the code that was featured on the limited edition Bill Cipher water bottle. I think it said "stay hydrated losers and don't trust everything you read in YouTube comment sections!"

[kazoorent]

32:26 it wasnt announced yet! Alex Hirsch revealed in an interview with Hana Hyperfixates that it was a prophetic joke slipped in by one of the animators for that episode!

[hashtagmoniz]

36:52 I originally also had issues with the “broken continuity” introduce by journal 3, but there’s a throwaway line by Dipper towards the end that says that the aftermath of Weirdmageddon restored the journals to their complete condition, thus magically regenerating previously lost pages. So, we’re supposed to assume that the book Dipper has in the series was missing a lot of content that was later saved. He even comments on how he wished he could’ve seen all that sooner

[flavoredramen]

Im so shocked that this video isnt viral yet. The pure dedication is crazy, had to give this my full attention.

[fabianl]

i knew most of the codes and things within the show but the further you got from it, with the dvd box set i was blown away. it’s so crazy how everything links up together. i’d absolutely loveee to see a follow up video talking about any new secrets that get discovered, there’s no way this will be the end of it all

[angelnegra]

I'd forgotten that Shion Takeuchi was a writer on Gravity Falls, so when you started bringing up keywords like Bearo and Inside Job, I had a mild moment of confusion, lol.

[showd]

1:02:48 that’s funny I assume that’s a reference to who people though Tad Strange was lol

[legostarscreamer]

Originally I put this on to listen to while I was drawing but I eventually had to put my book down and pay my full attention the whole way through because this video is very well crafted! Thanks for the awesome upload dude!

[tylervlogs]

This is insane the amount of dedication that went into this

[kenji]

The ‘90s cartoon parody is actually a promo image of the Burger King Kid’s Club

[somethinunameit]

Alex Hersh made a beautiful show. He made millions fall in love with a small town and now has given the show the best sequel ive ever scene. Sure the lore doesnt quite make sense, but the spirit of the show is thriving

[peytonestep]

I'm absolutely so proud and dying at the fact that the search "peak" = gravity falls complete series on DVD that's master class trolling

[godomoths]

While stan singing "We'll meet again" might make it seem like he is still at least somewhat posessed by Bill, I feel like shaking the statues hand would not make you make a pact with Bill. After all it's stated several times that the statue is just the bodily remains of Bill, presumably his" shell" he needs to traverse the 3rd Dimension, while he himself actually lives on somewhere else in a different form.
This would also make sense as we know that the hengemaniacs now live in a dimension named R34LITY which seems to be our Dimension, implying that gravity falls plays in a different Dimension.
Why the shell of Bill would be left in R3ALITY instead of the gravity falls World is a mystery but maybe the hengemaniacs maybe just brought it here?

[pedromartinez]

Dude this is JUST what I've been looking for. The gravity falls wiki is super useful but i always felt that they should explain where the codes come from and how they were solved. I especially feel this way about Bill's cipher since it just takes you to the GF episodes now
