Black Mirror Season 4: 10 Easter Eggs You Totally Missed
3. White Bear Exhibits
Also among Black Museum's collection of self-referential exhibits are relics from season two's White Bear. The mask worn by the man who threatens Victoria Skillane as part of her elaborate punishment can be seen among the installations.
This, of course, may not be the actual mask worn by her tormentor, Baxter. There's a chance it's merely a replica since there's no evidence to suggest the White Bear Justice Park ever stopped running in the Black Mirror universe.
Video footage of Victoria can also be seen playing in the museum.
