Hopefully, they can pull it all together, and maybe even have time to pull Hopper out of his prison camp.
Provided Hopper can’t do that himself, which I have no doubt he could pull off.
Things aren’t looking good for Hopper, but based on Gaten Matarazzo describing Season 4 as the “scariest” Stranger Things has done, it sounds like things could be rather dark all around.
It’s doubly bad then that Season 3 ended with the kids being split up, which will make any Upside Down threat to come that much harder to face.
