🚨Warning: A year's worth of spoilers ahead! 🚨
1. First, one of the biggest Easter eggs from this year: In The Haunting of Hill House, you can spot multiple hidden ghosts throughout Season 1.
2. Also in The Haunting of Hill House, you can tell when one of the Crains is in the Red Room by the vertical window that appears in all of them — there's also something red in each room.
3. And the fact that each of the Crain siblings represent the five stages of grief: Steve is denial, Shirley is anger, Theo is bargaining, Luke is depression, and Nell is acceptance.
4. In The Good Place, Tahani decides to delete all the best celebrities from her phone — you can spot The Rock, The Queen, The Edge, and Taylor Swift among some others.
5. And you can catch Eleanor's previous Google searches as well as some funny suggestions in The Good Place Season 2 finale.
6. Also in The Good Place, you can spot Li'l Sebastian from Parks and Recreation during the pick-a-pet fair.
7. In This Is Us, you can see that Jack's wearing a green t-shirt during his first date with Rebecca — this is the magical shirt he later gives Kate at the pool in Season 1.
8. In The Handmaid's Tale, June finds a Friends DVD box set and watches an episode while hiding.
9. In the Riverdale flashback episode, FP's cast matches the one Eddie wears in the movie It.
10. The Riverdale flashback episode also features several nods to The Breakfast Club, including Betty's fingerless gloves.
11. Also in Riverdale, the quote on the blackboard behind Hermione is from Macbeth — it basically talks about a bunch of people who are marching closer to their deaths — this goes with the Gryphons & Gargoyles theme in Season 3.
12. In Castle Rock, there's a map that showcases some famous locations from Stephen King novels — most notably you can spot Derry, which is where It is set.
13. In Chilling Adventures of Sabrina, Sabrina's red dress with the lace collar is an homage to Mia Farrow's dress in Rosemary's Baby.
14. Also when Sabrina enters her house for the first time in Chilling Adventures of Sabrina and turns the radio on simply by using her finger, it's an homage to the original comic and the Melissa Joan Hart series.
15. And in Chilling Adventures of Sabrina, there are several Riverdale and Archie comics Easter eggs, including this poster for a bowling championship between the Greendale Ravens and the Riverdale Bulldogs.
16. In AHS: Apocalypse, the song "Tonight You Belong to Me" plays when Michael Langdon appears for the first time — the song also played in Murder House's premiere and finale as well.
17. In 13 Reasons Why Season 2, if you look closely, it appears that cassette tapes are no longer part of Baker's Pharmacy's inventory — this is because of Hannah's tapes in Season 1.
18. Also in 13 Reasons Why, someone wrote that they wished they could still get hot chocolate with Hannah, a callback to Alex, Jessica, and Hannah's dates to Monet's in Season 1.
19. In The Walking Dead, Maggie's office at Hilltop features portraits of Hershel, Glenn, Beth, and a few others.
20. In Big Mouth Season 2, Maury has a note reminding him to buy Aerosmith tickets — this is a nod to the iconic line from Dazed and Confused.
21. In Legacies, you can spot a special case dedicated to Stefan Salvatore at the Salvatore School for the Young and Gifted — The Vampire Diaries fans might notice Stefan's journals, his daylight ring, and a necklace he gave Elena.
22. Also in Legacies, a student's history homework includes reading a chapter about Klaus Mikaelson — Klaus was of course a main villain in The Vampire Diaries and Hope's father.
23. In Maniac, Annie stops in front of the Milgrim Industries headquarters and throws away a Rubik's cube — Owen Milgrim then picks it up and it's used by him throughout the series.
24. In Daredevil Season 3, there's a poster behind Karen advertising a Parker vs. Morales fight — this is a nod to Peter Parker and Miles Morales, who both take up the Spider-Man mantle.
