Black Mirror Season 7: All the Easter Eggs in USS Callister: Into Infinity you Might’ve Missed

“USS Callister: Into Infinity” isn’t just a nostalgic return to one of Black Mirror’s most beloved episodes—it’s a sprawling celebration of the anthology’s entire twisted universe. From sly callbacks to deep-cut references, this episode is overflowing with Easter eggs that connect nearly every corner of the Black Mirror multiverse. 

Series Creator Charlie Brooker himself said that the “USS Callister” episode within itself is an Easter egg.” (via Independent UK) Let’s break down every nod, cameo, and blink-and-you’ll-miss-it reference in this ultimate Black Mirror crossover.

Mohawk’s Outfit: A Badge of References

Keep a close eye on Mohawk (played by Gwion Glyn), one of the gamers inside Infinity. His vest is patched with more than just rebellion—it features several icons from past episodes, including the ominous “White Bear” (Season 2, Episode 2) glyph, as well as logos from Men Against Fire and Arkangel (Season 4, Episode 2). It turns out, every character inside Infinity wears the Men Against Fire emblem. Subtle? Not at all—and we love it.

Pixie and Ashley O: Still “On a Roll”

Pink-braided gamer Pixie (played by Iolanthe) jams out to none other than Ashley O’s hit track “On a Roll” from Rachel, Jack and Ashley Too (Season 5, Episode 3). Not only is the song playing on her headphones during a crucial chase scene, but it’s also still blasting from her computer later in the episode. A poster of Ashley O can be spotted in the background, turning this reference into a full-on tribute.

The “Back for Vengeance” Comic

When Walton (Jimmi Simpson) rifles through Daly’s old belongings, he finds a Space Fleet comic titled Back for Vengeance. The cover is a treasure trove of Black Mirror lore: Waldo the blue bear (from Season 2’s The Waldo Moment), the White Bear glyph, and even a robotic dog from Metalhead are all front and center. This single frame is practically a museum of dystopian callbacks.

Daly’s Garage of Nightmares

In a flashback set 12 years prior, we revisit Daly’s garage—a shrine to all things Space Fleet and an early warning sign of his obsession. Among the memorabilia is a pair of teal boots once worn by Nanette (Cristin Milioti) in the original USS Callister. There’s even merchandise from SaitoGemu, the company featured in Playtest (Season 3, Episode 2), and a poster for Valdack’s Revenge, first seen in Bandersnatch and later as a character in USS Callister.

The Hospital Connection: San Junipero Lives On

Nanette is shown hospitalized at St. Juniper’s Hospital—yet another nod to San Junipero, the emotional Season 3 episode. St. Juniper is also the hospital featured in Black Museum, tying multiple realities back to TCKR, the company behind simulated consciousness. It's a subtle but powerful piece of connective tissue in the Black Mirror timeline.

Welcome Back, Nida and Gaap?

Yes, you saw that right. Nida and Gaap from Demon 79—last season’s Red Mirror episode—make a surprise appearance during the final Infinity battle. Anjana Vasan (Nida) and Paapa Essiedu (Gaap) are spotted among the players hunting our heroes. Why is Nida dressed in a devil costume, though, when Gaap is the actual demon? Let the fan theories begin. This marks Anjana Vasan’s third Black Mirror appearance, having also played a Space Cop in Nosedive. She’s officially a Black Mirror MVP.

The Ticker: Brooker’s Final Gift Basket

As James Walton is arrested, a news ticker runs beneath the broadcast, packed with Easter eggs. According to Brooker: “If you watch the news ticker at the very end, there’s a bunch of Easter eggs in there.” (via Independent UK) He’s not wrong. The headlines include:

• “Hotel Reverie Reboot Hits Streamberry” – an obvious “Hotel Reverie” and “Joan is Awful” reference
• “Thronglets 2 Launches to Critical Acclaim” – from Plaything
• “Rivermind CTO Steps Down” – from Common People
• “Former UK PM Michael Callow Enters Celebrity Vet School” – a brilliant callback to the infamous National Anthem
• “Mysterious Talisman Found in Plane Wreckage” – a nod to Demon 79.

And yes, poor Michael Callow (Rory Kinnear) still can’t escape that incident with the pig.

Cameos and Surprise Guests

Popular YouTubers DanTDM and TommyInnit are spotted as part of the gamer horde. Meanwhile, the final space battle features the return of Anjana Vasan and Paapa Essiedu—marking a surreal crossover moment between Demon 79 and USS Callister. 

“There’s a human Easter egg – a character from ‘Demon 79’ pops up in the space battle,” said Jessica Rhoades. Brooker added: “The character of Pixie they meet is listening to the song by Ashley O.”

Even more Hidden Details

• A carton of Raiman chocolate milk, previously seen in USS Callister, is back.
• One gamer’s banner reads “Ashley O,” doubling down on the Miley Cyrus reference.
• The phrase “Infinity Improbability Drive” sneaks in a cheeky Hitchhiker’s Guide to the Galaxy reference, in addition to homages to Star Trek and Star Wars.
• Space Fleet Magazine features even more callbacks, including the Waldo bear and the knife-wielding robot dog from Metalhead.

With USS Callister: Into Infinity, Black Mirror doesn’t just revisit a fan-favorite—it opens the door to a fully interconnected universe. Brooker and co. have managed to turn one episode into a multiverse of madness, where Ashley O, Waldo, Nida, Gaap, and even Michael Callow collide. This isn’t just fan service; it’s a reward for viewers who’ve followed the show’s grim vision of the future from day one.
