Complete story — includes the ending
In Camazotz, the kidnapped children awaken, and while most believe Henry's claim that he saved them, Holly and Derek do not. Max and Holly traverse Henry's memories of Holly to search for an escape as Derek distracts him. Henry discovers the plan, threatens Derek's family, turns into Vecna, finds Holly, and strangles Max. Will's group reanimates a dead Demogorgon using the radio tower's voltage so Will can reconnect to the hive mind and kill Vecna. Will possesses Vecna's body, breaking his leg and speaking through him to tell Max and Holly to run; Henry expels him from his mind soon after, causing Will to pass out. In the Upside Down, Hopper and Eleven escape the military base with Kali, who reveals Dr. Kay was using her blood, just as Dr. Brenner used Henry's blood, in failed experiments to give children powers. At Hawkins Lab, Dustin theorizes that the wall surrounding the Upside Down is a protective shield that, if destroyed, can weaken Henry. Nancy and Jonathan find a mysterious sphere on the roof of the lab. Dustin finds Brenner's journal and realizes he is wrong, but fails to warn the others before Nancy shoots the sphere.
