The Mind Flayer’s grotesque plan comes into focus in episode six of Stranger Things 3, “E Pluribus Unum”, the meaning of the title seeming obvious in retrospect. Aside from the citizenry of Hawkins literally pulling themselves together to stop El and the gang, we get some very sympathetic backstory for Billy, Dustin throws a tea party for Erica, Robin and Steve share a moment in a Soviet medical torture facility, and Mike confesses his love for El.
