When the Netflix thriller series You premiered three years ago, it started a lot of conversations. The show was told largely from the point of view of a charismatic serial killer named Joe, played by Penn Badgley, and it followed his obsession with and stalking of a young woman. Now in its third season, Joe hasn't changed much as a person, even though his circumstances have. He has a wife now, and a baby, although he's hardly living the typical suburban dad life.
