Stranger Things bosses say one major question will finally be answered in season 5

Stranger Things season 5 will be the final outing for the Netflix series and the Duffer Brothers have promised it will finally answer the show’s biggest mystery

Stranger Things is set to return on Netflix with part one of season five landing on November 26.

The series will be divided into three volumes, with the first four episodes releasing simultaneously, setting the scene in autumn 1987.

As Hawkins bears the scars from the opening of the Rifts, our heroes must unite one final time to locate and defeat Vecna (portrayed by Jamie Campbell Bower) following his disappearance.

Complicating matters further, the town is under military quarantine and Eleven (Millie Bobby Brown) has been compelled back into hiding.

With the final showdown approaching, the Duffer Brothers assure that the series will at last reveal the true nature of the Upside Down.

In a conversation with Variety, co-creator Ross Duffer stated: “Every season would be like, ‘Should we talk about it?’ And we’d go, ‘No, let’s wait.’ And then finally, we’re like, ‘Well, we have to now!'”

Matt Duffer added regarding the final outing: “We knew roughly what the end scene was for years – it wasn’t something we had a strain to come up with.

“There were elements of it that were discussed for weeks, but the core idea of the ending, we had for a really long time.

“Anyway, we’re really happy with the way it ended. It’s nerve-racking to put it out. I’m sure people will have opinions.”

There are numerous fan theories about the origins of the Upside Down, with some speculating it was created by Vecna as part of his ambition to rule Hawkins.

Alternatively, some speculate that it was Eleven who created the alternate world as an extension of her subconscious.

Production designer Chris Trujillo has previously suggested it was El who created the Upside Down, having spoken on the official Stranger Things YouTube channel.

He stated: “The moment that the Upside Down was quote-unquote ‘created’ inadvertently by Eleven, the set dressing and the world of the Upside Down is frozen in that moment.

“So like when we’re in Nancy’s room, we’ll discover in the Upside Down that Nancy’s room is as it was season one when we first were introduced to it.”

Stranger Things season 5 part 1 will be available on Netflix from November 26.
