I know some people are still watching Stranger Things 2...so no spoilers! BUT we are starting to get some info about the third season.
The creators, the Duffer brothers said we could see these things:
. A time jump with the kids
. The party is entering high school
. Eleven kinda upset that weird monster...so it's possible he could be after her.
. We could see more kids like Eleven
. And hopefully more babysitter Steve #TeamSteve
