Whoever Adams plays, it's safe to say that his appearance is a game-changer. "I think it will leave people wondering, 'What next?'" Klemmer says. "This show, it's almost like an anthology show. It's not like True Detective, in that all the characters are changing and all the stakes and stories, but it's got a little of that DNA. I think, in a lot of ways, it's going to feel like a new TV show in Season 2."
