'Stranger Things' season 2 spoilers: Will continues to see the Upside Down in Hawkins, Barb's death is settled and Eleven reappears

“Stranger Things” took the world by storm when it was released by Netflix in July last year. And while so many things happened to the characters in season 1, season 2 seems to be more jam-packed. Will is having visions of the Upside Down, Barb’s death is going to be settled and Eleven makes her return to Hawkins.

The official synopsis of the upcoming season confirms that the stage is set a year after the cliffhanger from season 1. The trailer, which can be watched below, meanwhile indicates that the first episodes will take place in Halloween. Independent UK has further reported that these episodes will also explore what happened to Will Byers (Noah Schnapp) and how the Upside Down has affected him physically, mentally and emotionally.

“He seems to be seeing images from the Upside Down -- the question is whether they’re real or not,” co-creator Matt Duffer said. “So it seems like he’s having some sort of post-traumatic stress disorder.”

The trailer revealed that Will is going to be under the care of what looked to be medical professionals. This makes it likely that there are people who do not believe Will’s stories of another dimension. How or when the town of Hawkins will be proven wrong is still unknown.

David Harbour, who portrays Jim Hopper in the show, however clarified that the death of Barb (Shannon Purser) will finally be explained. “We will tell you that we do deal with the loose ends in season 2,” Harbour said. “We do deal with some of the internet rage over Barb’s death. We will have justice for Barb’s death in some sense.” But while her death is finally going to be explored, Harbour did make it clear that the character is “very much dead.”

When it comes to Eleven (Millie Bobbie Brown), the Duffer brothers have been quite mysterious. “We don’t know about Eleven,” Ross Duffer said. “We leave that up in the air.” The trailer does, however, give us a glimpse of the character, but it is unclear whether or not she is in the Upside Down. From her expression, it looks as if someone finds her.

“Stranger Things” season 2 will return on Oct. 31. It will be available to watch internationally on Netflix.
