The play reveals that the cave system was where Henry first ventured to Dimension X — now dubbed "The Abyss" in Stranger Things. That's the alternate dimension where the Mind Flayer and Demogorgons are from, as opposed to the Upside Down, which Volume 2 reveals is a bridge connecting the Abyss to our world.

Now streaming, episodes 5, 6, and 7 were a relatively bland stretch of the show. They include a breakup, a big Will reveal, and more underwhelming moments.

Creators Matt and Ross Duffer have confirmed that Stranger Things season 5, volume 2 has resolved the Nancy, Steve, and Jonathan love triangle for good.
