"We’ve thought about it," Brooker said. "There were aspects of the story that I took out. For instance, I’d originally written a scene where Gugu’s character, Kelly, is in a kindergarten and there are children there and when you realize what’s going on, it’s that these are deceased children. It was too sad and too poignant of a note to hit in that story, but I kept thinking about how that felt like a whole world in and of itself. I think we almost might do it in a completely different form if we were doing a straight sequel, if that makes sense. Maybe not even as a normal episode."
