Stranger Things 4 finally revealed how Hopper survived the ending of the third season. Spoilers ahead for the newest season of the Netflix show! Surprisingly, Hopper merely fell down to a lower platform during the blast. When things started to kick into high-gear, the sheriff made a business decision to jump and it paid off. Sure, the force of the blast knocked him out, but he survived. Upon waking up, he tried to pull himself up the ladder back to where he was standing. Unfortunately for Hopper, there were some Russian agents there to greet him. Hence why we see him in the wintry climate during the teasers for Stranger Things 4. It might not be the answer that some people were looking for, but it does make a measure of sense. All those wild theories about him being blown into the Upside Down or getting killed by the blast and resurrected by the Russians seem to be for naught.
