Still, even though he knew what was coming, he didn’t know any of the specifics until he was sent the final script. “I didn’t want to know. I didn’t want to have scenes with that in the back of my mind,” he explained. “I didn’t want it to influence how I went about the scenes. I felt it was safer to just not worry about it and keep it as a secret. And fortunately no one in our cast or crew let it slip because some people did know from the get-go. They were great in keeping it a secret from me. Thank goodness.” Prentice said he thinks the identify of his killer makes perfect sense — not that he saw it coming. “I could see why when I read it was Alex. I was like, ‘Yeah, I get it,’ ” he said. “I knew it wasn’t Zach, so I knew that there was more to the story than that and I always assumed that Jess might be involved. So I had parts of the puzzle sort of mapped out, but not the whole picture. So that was a fun little surprise.” 13 Reasons Why season 3 is streaming now on Netflix. The show has already been renewed for a fourth and final season.
