Sorry if this has been mentioned already but this is a long thread. Just finished the season and I thought every episode was really fun. Love me some Black Mirror. I think my favorite was Black Museum. Is it the first timea Black MIrror episode has referenced other episodes? I don't remember that happening before. I picked up on three references --- the lollipop from the USS Callister, a reference to old people going to the cloud from San Junipero, and the guy reading a 15m Merits graphic novel. Were there any other references?
Other Eps in former seasons had references to other Eps too.
