Ever since I finished binging Season 3 of Stranger Things over the Summer, I've been excited to find out what happens next. On Wednesday the Duffer Brothers posted a photo on Instagram of the finished script for Episode 1 of Season 4 and revealed the title which is, "Chapter One: The Hellfire Club." Several fans pointed out that The Hellfire Club is a group that hates mutants (like Eleven) and often comes into conflict with the X-Men. Their first appearance in Marvel comics came in 1980, so the Duffers and their gang of 80s kids could very well be referring to that group. Season 4 starts filming in August of 2020, so people are speculating that it will hit Netflix in December of 2020, but nothing official yet.
