Premieres: Friday, Oct. 27

Where We Left Off: Eleven (Millie Bobby Brown) seemingly sacrificed herself to defeat the Demogorgon, while Hopper (David Harbour) and Joyce (Winona Ryder) rescued Will (Noah Schnapp), who coughed up a slug in the finale's final moments, thus promising the fight wasn't over.

The Scoop: Fans of the show's teenage love triangle involving Steve (Joe Keery), Nancy (Natalia Dyer) and Jonathan (Charlie Heaton) should gear up for a pretty awesome Season 2; it sounds like Team Jonathan fans might have an opening for their 'ship in the wake of Barb's (Shannon Purser) death. "At the beginning [of Season 2] Steve and Nancy have been together for like a year, which in high school is a really long time," says showrunner Matt Duffer. "Nancy's been dealing with some stuff -- for instance, her best friend is dead. Whether Steve is the most supportive boyfriend in regard to that, we'll see. The love triangle lives on."

New cast members for Season 2 include '80s movie icon Sean Astin as Bob, a new love interest for Joyce; Paul Reiser as Dr. Owens, the new head of the nefarious lab that raised Eleven; and Dacre Montgomery and Sadie Sink, who play mysterious siblings Billy and Max.
