Spoiler Alert: If you are not a member of the 18.2 million households who have reportedly binged “Stranger Things 3” in four days, prepare for a Mind Flayer-sized spoiler.

The creators of “Stranger Things” know exactly how to stir the pot. The presumed death of a beloved fan-favourite had Twitter in a frenzy. The season’s final scene suggested that character may still be alive, but the Duffer Brothers don’t want you to read into it too much.

“You definitely should not assume anything,” co-creator Matt Duffer said of the post-credits scene, which revealed the Russians are in possession of a Demogorgon. When walking by a number of prison cells, one Russian soldier tells his cohort not to grab the “American” prisoner.

This has led people to believe that police chief Jim Hopper (David Harbour) — who seemingly perished in an explosion in the final episode — may somehow have survived and been captured. “The line that Russian guard said is purposely intended to spark debate,” Matt expressed in an interview with Entertainment Weekly. “We need people to ask the very questions that you’re asking.”

“Assuming there’s a season 4, obviously the question of who that American is in that cell and then also what they’re doing with the Demogorgon, that is a tease,” co-creator Ross Duffer chimes in. “We try to tee up some season 4.”

The season concluded with Eleven (Millie Bobby Brown) losing her supernatural powers. “We didn’t want an ending again this year where Eleven comes in the last second and holds out her hand and saves the day,” Ross added. “Moving into season 4, how much more vulnerable does that make our characters in a group?”

“Inevitably, evil resurfaces that they can’t just lean on Eleven to come in and save the day,” he concluded. “We think it ups the scare factor in a big way.”

“Stranger Things 3” premiered on July 4 and has — according to Netflix — been watched by more than 40 million households in just four days.
