Dacres known about it.
Weve all known about it.
Now, I didnt know specifically it was going to turn into what it turned into.
But I knew that it was going to get really dark.
What [the Duffers and I] did discuss, however, was the biological-mother components.
That was something I actually brought to them about two or three months before they started writing season 3.
I had written a whole backstory, and this just speaks words to them because theyre super-collaborative.
So I wanted to know like, where did he come from?
Because we never spoke about that in season 2.
Thats why she reaches into my memory.
Thats why thats there.

A big part of me.
I think I am in some respects, and some, you know, some respects Im not.
