Season 2 has a lot more variety in locations than season 1, and a bigger scale. I suspect a return to the labs and school, and visits to the junkyard. The plus is far more of season 2 takes place in the “upside down.” The finale is likely Hopper and Eleven suspended above you as you walk through the pit with a projected Mindflayer. It’s a better ending than the Void.
And, with that, Season 2 is only thing I’m 100% on. I’m about 70% confident on my Clerks and Family Guy clues, but I’m hearing more about red herrings and searches for leaks than I am houses at this point.
