The serial killer thing is such a head scratcher to me as people, my friends are texting me like, 'I'm calling it! I'm on [Episode] 6 and you're going to be fucking killing someone by [Episode] 10!' I don't understand it. I don't understand it, because that's not what I was playing in my mind. But it's interesting to me that's what people are seeing. It's based on John Douglas, who did not become a serial killer. Also, he talks a lot in his books and emails to us, he always talks about the epic emotional toll and physical toll [of] talking to the serial killers, but more so talking to the victims, and how it wore on him and changed him and how he almost didn't survive. To me, that's what we're playing and honoring in Holden's journey.
