Netflix just released a teaser trailer for Stranger Things 4, and it answers the question fans have been asking since the final battle at the Starcourt Mall from last season.

"Is Jim Hopper really dead?"

Goods news, Stranger Things fans. Jim Hopper, played by David Harbour, didn't die in the dramatic explosion which destroyed a machine that was re-opening a passage to the Upside Down. Instead, he apparently ended up in a prison camp somewhere in the frozen tundra of Soviet Russia. How that happened is still a mystery, but one thing is certain; Fan-favorite character Jim Hopper is back for another season.
