Stranger Things season 4: Hopper ISN'T alive as fans spot key promo clue?

The shot showed off a large group of men chained together, digging out a railroad.

As the camera panned around the men, it was revealed Hopper was involved in digging the road, as he pulled his hood off, revealing a bald Hopper for the first time in the show.

As fans rejoiced at the return of their favourite character, it seemed as if all the problems had been solved – but viewers also pointed out something particularly worrying about the trailer.

The final seconds of the brand new clip featured an ominous whining concluding the video.
