You showrunner Sera Gamble teases what the show’s potential ending has in store for Joe Goldberg, and it does not bode well for the character. Starring Penn Badgley as the series’ deeply disturbed protagonist, the previous seasons of You introduced audiences to Joe’s troubling cycles of obsession, deception, and murder as he inevitably became fixated on a series of women he believed to be his soulmates. Most recently, Netflix released You season 4 part 1, with the new episodes showing Joe relocating to England under another assumed identity and unexpectedly finding himself subject to the whims of another deranged killer.
