Basically, with Max’s “death,” Vecna is able to open a fourth gate from the Upside Down to Hawkins, which means ALL HELL ESSENTIALLY BREAKS LOOSE and a bunch of innocent people die from a sudden “earthquake” (it was absolutely NOT an earthquake). Oh, and Will confirms that Vecna didn’t die and is just hurt, and they need to kill Vecna orrrrr everyone will die. Cool, cool, cool…
