Remember that mention of an American in that odd scene at the end of season 3 of Stranger Things? Well, looks like we know who that American is for sure.
Netflix just released a teaser for season 4 of Stranger Things, and it only confirms what pretty much everyone already knew after watching the final mysterious scene at the end of season 3.
And we can say now that Hopper lives!
Yes, folks, it looks like he’s back, maybe with less hair, but we’ll take him any way we can, right?
So, what we know is that Hopper is alive, but he’s in Siberia, Russia. How he got there we don’t know. How he’s alive, we also don’t know. Hopefully we’ll find out soon enough when Stranger Things returns in 2021.
