My mind (flayer) is blown.

The radio channel Hop uses to communicate with Eleven with is channel 11.

UM, adorable.

The secret knock Hop and Eleven use spells out "us" in Morse Code.

Two dots and a dash for "U" and three dots for "S."

Mrs. Wheeler's romance novel cover was apparently photoshopped to look like Billy.

Bob notices "Sattler's quarry" when he's looking at Will's drawings — which is the same location where Will's (fake) body was found in Season 1.

BOB.

Speaking of Season 1, the scene where the kids are playing Dungeons & Dragons in the very first episode lines up creepily perfect with the Demogorgon scene in Episode 8.

You can watch the whole side-by-side video here. Seriously, it's great.

And in the first episode of Season 1, Joyce does this very subtle, but kinda funny (and also very sweet) thing where she reaches for Will's shoulder.

Adorable and sad!

In Season 1, Lucas and Dustin (kinda) joke about how they think Eleven might be an escaped mental patient, like the Halloween character Michael Myers. Ironically, in Season 2, Lucas's and Dustin's crush Max is actually dressed as Michael Myers.

Cosmic irony, man.

When Mike has to pick out toys for the yard sale in Season 2 he lingers on a dinosaur — which is one of the toys he first showed Eleven back in Season 1.

RORY! (Like, "Roar-y!")

Eleven tells time "weird" because it's just the way Mike taught her back in Season 1.

But, obviously, El is a fast learner and by Season 2, Episode 5 she's saying "five-fifteen."

The word "evil" is clearly written on the bathroom stall when Dustin finally finds Dart.

Ominous AF, no?

One of Kali's gang members is named Funshine, as in the Care Bear Funshine Bear — which is the exact Ben Cooper Halloween mask he wears, too.

Kali even says, "Don't let his size frighten you. Fun's a teddy bear."

The story of "Baby Fae's Baboon Heart" on the cover of Hawkins' newspaper in Season 2, Episode 1 was a real news headline in 1984.

You can learn more about the story of her dramatic heart transplant here.

Speaking of this Hawkins newspaper, this is the same edition Lucas's dad is reading — a few days later, mind you — in Episode 5.

It's the '80s, maybe news doesn't get around as fast? Or, ya know, production budgets, etc.

The book Hop reads to Eleven in Season 2 is Anne of Green Gables, which is the same book he read to his daughter Sara in Season 1.

Crying.

Eleven sees a trailer for the movie The Terminator in Episode 2, which is the same movie that's playing at the movie theater in downtown Hawkins.

For the record, The Terminator was released on Oct. 26, 1984, while the timeline of Stranger Things 2 starts on Oct. 28, 1984.

The song Hop chooses for him and Eleven to clean to is called "You Don't Mess Around With Jim," which is both cheeky and adorable.

'Cause, ya know, that's his name.

And finally, the "Boy Who Came Back To Life" article reads VERY differently in Season 2 than it did in Season 1.

Season 1 reads: "The former missing child Will Byers has been found after a week of searching. He is presently in stable condition in Hawkins General Hospital. Byers' mother, Joyce Byers alleges that Will was the subject of a secret government program run by the Hawkins National Laboratory. The allegation comes amidst a massive investigation into the hidden organization and its elaborate experimentations in perusal of mind control."

Season 2 reads: "In a recent statement, the state coroner's office has admitted to misidentifying the body recovered from the Sattler Quarry as twelve year old Will Byers. Will Byers had gone missing two days prior, inspiring the town of Hawking to form a search party in the hopes of finding him. When a boy's body was recovered from Sattler Quarry, the case seemed solved. Six days later local police, lead by Chief Jim Hopper, found Byers alive in an abandoned cave a few miles outside of Hawkins."
