Stranger Things 2 Plot Details, Images Released

You never want to embark into the Upside Down without at least some idea about what to expect.

The first teaser for the second season of Stranger Things revealed that we'll return to Hawkins this Halloween, and now Entertainment Weekly has uncovered a bunch of details about what's in store.

Confirming previous reports, Season 2 will open on Halloween 1984, picking up nearly a year after the events of the first installment. The kids (Will Byers included) will be in their Ghostbusters costumes, and (gauging from the new photos) Eleven will be rocking another interesting haircut.

However, all is not well with young Will. "He seems to be seeing images from the Upside Down–the question is whether they're real or not," said co-creator Matt Duffer. "So it seems like he's having some sort of post-traumatic stress disorder."

Meanwhile, Will's mom Joyce (Winona Ryder) is dating Bob (Sean Astin), the owner of a local Radio Shack, while Hopper (David Harbour) attempts to keep all the craziness from last year firmly under wraps.

"It kind of falls on Hopper to be the voice of authority to say, 'This did happen and this didn't happen,'" said Harbour. "He's struggling with the compromise that takes him to, having to lie and cover things up."

At the same time, a few newcomers shake up the town's dynamic: brother-sister duo Billy (Dacre Montgomery) and Max (Sadie Sink). Max becomes pals with the boys (attracting a little romantic interest from Lucas and Dustin), but Billy isn't quite so friendly. Duffer said, "Stephen King always has really great human villains. The evil in the real world is often as bad or worse than the supernatural evil, so we wanted to introduce a character like that."

But there are, obviously, stranger things going on. The gateway to the Upside Down remains open, along with the lab, now run by Dr. Owens (Paul Reiser). And although details about the monsters we'll see are still top secret, Duffer said the second season will explore "different kinds of horror." But there's a cute side to all the supernatural elements, too. Dustin (Gaten Matarazzo) will find himself a polliwog-like pet. "It's a little creature I get to bond with," Matarazzo said. "It's obviously not from this planet or this dimension."

While we begin stocking up on Eggo waffles, check out the untold truth of Stranger Things and the ending of Season 1 explained.
