In December, Season Three of Succession ended with three of the four Roy siblings uniting—for the first time in the series—to seize Waystar Royco, the family media conglomerate, from their father, Logan (Brian Cox). Unbeknown to the Roy children, Tom (Matthew Macfadyen), the bootlicking husband of Shiv Roy (Sarah Snook), revealed the plot to Logan. Season Four, the show’s last, begins with an attempt by the siblings to challenge their father. But little is known about what’s to come—most in the cast weren’t even aware the show was ending until the last table read. For the fate of Waystar Royco, you’ll have to watch to the very end. —Jensen Davis
