Yes, yet another cable banner coming at you! This time around, the Easter egg is for season four's third episode, "Crocodile" — "UK Police Test Groundbreaking Memory Recall Device." If that doesn't ring any bells, the episode stars Andrea Riseborough as a successful architect who finds herself getting caught up in violence as she tries to cover up a hit-and-run from years earlier. The police are able to nab her in the end thanks to a device that can look at peoples' memories, which has apparently been around the Black Mirror universe since the '80s.
