What’s Happening in the Finale?

  • The UK finale was an extended, high-stakes episode wrapping up weeks of betrayals, banishments, and late-game twists, with its special later time slot to fit everything in.
  • The Peacock Season 4 finale centers on a small endgame group of Faithfuls vs. Traitors in a classic final-ceremony showdown, with questions over whether the remaining players can smoke out the Traitors before it’s too late.
  • After the U.S. finale, a reunion episode dives into grudges, strategy talk, and behind-the-scenes tension.
