Stranger Things Season 2 Clip Reveals How Eleven Escaped The Upside Down

One of Stranger Things' biggest mysteries has been solved. A new clip from the upcoming second season reveals how Eleven (Millie Bobby Brown) escapes the Upside Down after the dramatic events of the season one finale.

The clip, which you can watch at the bottom of this article, was released at MCM Comic Con in the United Kingdom. After an introduction from Brown, the clip goes on to show Eleven in the Upside Down version of Hawkins Middle School. As the scary sounds of a monster can be heard in the background, Eleven comes across a portal, which she quickly realizes will take her to the real world. She uses her powers to make it big enough to walk through and pops out, tired and covered in goo, into the hallway.

We know from the epilogue at the end of season one that Eleven doesn't go straight home, and rather decides to hide in the woods for a while with the help of Hopper (David Harbour). Eventually, though, as shown in the recently released final trailer for season two, she will get back in touch with her friends, helping to fight against a new, scarier monster threatening Hawkins.

Stranger Things season two is set to take place around Halloween of 1984, a year after the events of the first season. The season will feature Will (Noah Schnapp) suffering from PTSD thanks to his time in the Upside Down, while Hopper tries to cover up the events of the first season to help protect Will and Joyce (Winona Ryder). The season is also set to introduce the series' "main villain," according to co-creator Ross Duffer.

Season two will bring in several new cast members, including Sean Astin as a former high school nerd and the new boyfriend of Joyce; Paul Reiser as a high-ranking member of the Department of Energy who now runs the lab; Linnea Berthelsen as an emotionally damaged woman with a connection to the supernatural events at the lab; Will Chase as a new parent in town; Sadie Sink as the boys' tough and confident new friend Max; and Darce Montgomery as her edgy and violent older step-brother Billy.

The rest of the show's cast includes Finn Wolfhard, Gaten Matarazzo, Caleb McLaughlin, Natalia Dyer, Charlie Heaton, Cara Buono, and Joe Keery. Stranger Things returns for season two on Oct. 27.
