    This post is full of spoilers, and not just for Season 4, but for the entire series. If you haven't watched every episode yet, proceed at your own risk.

    Netflix

    1. Kirsten Dunst appears in the episode "USS Callister."

    Netflix

    Jesse Plemons, who played Callister CTO Robert Daly, is Dunst's fiancé, so she did a surprise cameo.

    2. Aaron Paul also made a special appearance.

    Netflix

    At the end of the episode, the troll with username Gamer691 who yells at the crew is voiced by Aaron Paul, who also acted alongside Jesse Plemons in Breaking Bad.

    3. Elena, the receptionist, is using the same dating app that appears in the episode "Hang the DJ" later in the season.

    Netflix

    4. In fact, the app made an appearance in an earlier season as well.

    Netflix

    The protagonist of "Playtest" (from Season 3) uses it to hook up during his travels around Europe.

    5. "USS Callister" was also not the first time we had seen Michaela Coel on Black Mirror.

    Netflix

    Coel appeared in the episode "Nosedive" in the third season. She's the airport employee who doesn't allow the protagonist to board the flight.

    6. In that first episode, the planets that are mentioned, Skillane IV and Rannoch, are both references to the names of the killers in the Season 2 episode "White Bear."

    Netflix

    7. In "Arkangel," Sara watches a violent scene on her tablet that probably looked familiar.

    Netflix

    It's actually a clip from the third-season episode "Men Against Fire."

    8. And her lunchbox has an old friend on it too!

    Netflix

    See it down on the bottom of the stroller? It's Waldo from the second-season episode "The Waldo Moment."

    9. When she's a bit older, Sara has a peculiar poster adorning the ceiling of her bedroom.

    Netflix

    It's a poster for Harlech Shadow, the game that is vital to the plot of "Playtest" during the third season.

    10. One of the porn movies featured in the hotel in "Crocodile" is Best of Wraith Babes.

    Netflix

    Wraith Babes was the porn show that was featured in "15 Million Merits" from Season 2.

    11. The song "Anyone Who Knows What Love Is (Will Understand)" is used several times throughout "Crocodile."

    Netflix

    The song has made several appearances on Black Mirror and has been played in previous episodes such as "Fifteen Million Merits," "White Christmas," and "Men Against Fire."

    12. The pizza restaurant that appears in "USS Callister," Fences Pizza, is responsible for the accident in "Crocodile."

    Netflix

    13. The article about the missing person in "Crocodile" has a secret message if you're paying close enough attention.

    Netflix

    It reads: "'Of course the real question is why anyone would pause what they're watching just to read a sentence in a printed-out newspaper article,' says a voice in your head — before advising you to go and share this finding on Reddit." (Don't worry, someone already shared it on Reddit.)

    14. In the abandoned house in "Metalhead," there is a postcard of San Junipero, in reference to the episode of the same name from the previous season.

    Netflix

    15. The season finale, "Black Museum," is full of Easter eggs.

    Netflix

    For example, among the objects in the museum is the DNA-scanning machine from "USS Callister."

    16. Also an artificial bee from "Hated in the Nation," from the third season.

    Netflix

    17. As well as the tablet that Sara uses to hit her mom in "Arkangel."

    Netflix

    18. The bathtub from "Crocodile."

    Netflix

    19. And in the background of one of the shots is a recreation of the suicide from the end of "The National Anthem."

    Netflix

    That's the person who orchestrated the series of events culminating in his own suicide at the end of the first episode of the series.

    20. The mask worn by the hunter in "White Bear" from Season 2.

    Netflix

    21. In the background of this shot is the gaming system from "Playtest."

    Netflix

    22. As well as an egg that looks like the ones used in "White Christmas" to store human consciousness.

    Netflix

    23. The mice that are experimented on are named Hector and Kenny.

    Netflix

    Which are the names of the main characters in the third-season episode "Shut Up and Dance," who are blackmailed into doing stuff against their will.

    24. Later on, Jack is reading a comic book called 15 Million Merits, which you should recognize from Season 2.

    Netflix

    In fact, what he's reading seems to be the climax of the season two episode of the same name.

    25. Finally, the last episode of the season includes several references to "San Junipero."

    Netflix

    The company that develops the technology to store consciousness is called TCKR, the same company that appears in "San Junipero." At some point, the museum owner says that he used to work at the St. Juniper hospital and Nish mentions when "they get old people on the cloud," in reference to the premise of the Season 3 episode.

    If you thought you had seen it all, open your eyes, because who knows what other surprises may be hidden in Black Mirror.
