The third season of Stranger Things introduced a slew of new characters and drama in the town of Hawkins, Indiana, but nothing was more talked about than the finale episode, which depicted the death of everyone’s favourite police officer, Hopper (played by David Hopkins).

The moment happened when Joyce (played by Winona Ryder) and Hopper switched off Russians’ machines, which caused an explosion that seemingly took Hopper’s life. But in the first teaser clip for the upcoming season, Hopper is shown alive and well – well, alive and imprisoned somewhere in the snowy mountains of Soviet-era Russia, anyway.

The teaser opens at what appears to be a Russian prison camp, showing a group of men doing work in the snow. As the camera scans the prisoners, it stops at one who pulls off his work hat and looks back, revealing a bald-headed, moustache-less Hopper.

As many fans of the show guessed, Hopper is “the American” who was referenced as being held captive by the Russians during the final, cliff-hanger scenes of season three.

In response to the teaser, Stranger Things creators the Duffer Brothers released a statement: “We’re excited to officially confirm that production on Stranger Things 4 is now underway — and even more excited to announce the return of Hopper.”

“Although it’s not all good news for our ‘American’; he is imprisoned far from home in the snowy wasteland of Kamchatka, where he will face dangers both human…and other. Meanwhile, back in the states, a new horror is beginning to surface, something long-buried, something that connects everything…”
