“We don’t want to write ourselves in a corner so we try to have these early discussions with the writers just to make sure that we’re setting ourselves up to go in the right direction,” says Ross Duffer. “We don’t know a lot, but we do know a lot of the big broad strokes. At the end of season two, we knew about Billy. We knew that the Russians were going to come in. We didn’t know the mall and stuff, but again, we know these big broad strokes. That’s sort of where we are in season four. We have the big broad strokes. It’s just now about filling in those lines in the details. We’re pretty excited about where it’s potentially going to go. Again, like we said, it’s going to feel very different than this season. But I think that’s the right thing to do and I think it’ll be exciting.”
