Many internet detectives started to wonder if this connection means Season 1 and Season 3 could take place in the same universe. Executive producer Scott Stephens weighed in and clarified if this was the case or not.
"Not really," Stephens told THR. "I guess it's set in the same fictional world everything is set in, right? The reference is kind of a nod to the [first season]. The stuff in Season 1 was based on the same sort of pedophilia stories that are mentioned by the documentary crew. That's kind of the connective tissue. It's just a fun way to tie things in."
I saw that. I always take comments like this with a grain of salt, for various reasons.
But my head-shaking reaction has to do with Stephens's hair-splitting of "universe" and "fictional world." When asked if season three takes places in the same universe as season one, Stephens replies "Not really. I guess it's set in the same fictional world everything is set in, right?"
If by "everything," he means everything to do with the all three seasons, then what's the difference? Universe = fictional world. That's what people are wondering. And he goes on to call it a "connective tissue" and that it's a "fun way to tie things in." He's being annoyingly coy about it. Just admit it; it's set in the same universe, or world, or reality... whatever you want to call it.
There's no logical reason for viewers to assume that all the TD seasons were set in the same fictional world, although it's certainly plausible. That's why it's a point of interest. Furthermore, making the connection between the dolls and the crooked spiral introduces a host of other formal questions: for example, is the mention of the crooked spiral a red herring presented to lead viewers off-track? Of course those involved in the show will avoid talking about the reference, because they don't want to give anything away.
And I realize that may have been an unnecessary "spoiler" in my previous post, but I figured maybe some people would want to figure it out for themselves. But it's not a spoiler about the narrative of season three.
