A viral fan theory called “Conformity Gate” suggests another episode of "Stranger Things" could arrive today, Jan. 7. Here’s what the clues mean and what Netflix and the Duffers have said.

The main concern of The First Shadow is how a kid like Henry Creel can become a remorseless child-snatching monster like Vecna. And over the course of the play, Henry's actions get more and more violent, leading up to the big Creel Murders that were a focus of Stranger Things season 4.

Matt and Ross Duffer are the focus of the documentary, but stars Millie Bobby Brown, Sadie Sink, Finn Wolfhard and Schnapp are among those who also share their experiences on the show and reflect on it coming to an end. Here, Radwan talks about how she directed “One Last Adventure: The Making of Stranger Things 5.”
