Everything We Know About Stranger Things Season 3, From the Premiere Date to the Cast

It's not just the Mind Flayer that was left a bit unresolved in season two. As we mentioned, both Kali and Dr. Brenner have storylines that need conclusions, as does Paul Reiser's Dr. Owens. And, well, let's not forget that Joyce Byers has a dead Demodog in her fridge. Oh, and the fact that Dustin may be in trouble after what he experiences in those twisted underground tunnels. Suffice it to say, the show will certainly have to address a few things as they push onward.
