The rats that Rolo Haynes talks about experimenting on are named Kenny and Hector, which are also of the names of the two main characters in Season 3’s “Shut Up and Dance.”
Guys so I just realized something interesting on Black Mirror, “Kenny” and “Hector” the rats from an experiment on Black Museum share the name of Kenny and Hector from Shut Up and Dance, where they are basically the experiment rats from the people blackmailing them #wowpic.twitter.com/9PqodYUg3t
