Matt Duffer and Ross Duffer talked to Vulture and revealed a thought about their successful and critically acclaimed Netflix series, “Stranger Things,” that is sure to scare the show's fans. The Duffer Brothers are thinking of making two more seasons after “Stranger Things” season 2 and that’s it.

Ross Duffer told Vulture, “We’re thinking it will be a four-season thing and then out.” Why? That is because, after the fourth season, the show’s main pre-teen cast of Finn Wolfhard, Millie Bobby Brown, Caleb McLaughlin, Gaten Matarazzo, Dustin Henderson, and Noah Schnapp “will be ready for college.”

Matt Duffer said they just have to keep adjusting the story and he doesn't know if they can “justify something bad happening to them once a year.”

After "Stranger Things," the brothers said they have an idea for a sci-fi blockbuster that would be “tonally very different.” “But that’s way, way off.”

A darker and emotional second season

The kids of “Strangers Things” also talked to Vulture and Noah Schnapp, who plays Will Byers in the series, teased of “more scary parts” in the coming season.

Schnapp will be more visible in this season given that he was trapped in the Upside Down last time giving him less screen time.

He will also have intense scenes as his character, Will, grapples with the aftermath of what happened to him in the other world. Schnapp’s fellow cast members were said to have been “blown away” by his performance this season.

Finn Wolfhard who plays Mike Wheeler, one of Will’s best friends described the upcoming season as “more emotional.” Wolfhard explained that the series is going to be more emotional because of the backlash of the events that occurred previously. He likened it to post traumatic stress disorder (PTSD).

Caleb McLaughlin, who played Lucas Sinclair, revealed that each of the adolescent characters is getting an individual story line and so we can expect a back story on every one of them.

Popular fan theory debunked

Millie Bobby Brown, who played Eleven, a girl with psychokinetic abilities, teased that fans have no idea what “Stranger Things” season 2 has in store for them.

Brown also debunked the popular fan theory that the Demogorgon, the monster that dwelt in the Upside Down, was actually the manifestation of Eleven’s psychological trauma.

Brown told Vulture not only the speculation is wrong but that no single fan has “cracked the code on the show.”

Millie Bobby Brown further said that the show’s creators want "Stranger Things" to be original and not the idea of someone else. The Duffer Brothers just “don’t want to do a fan theory,” Brown said.

“Stranger Things” season 2 starts streaming on Netflix October 27.
