In the season finale, Poppy and Georgie Carlton immerse themselves in American holidays, learning about the lovely pre-Christmas event that is Thanksgiving by attending and giving a speech at a parade before making themselves at home with a host family who are kind enough to offer them dinner. They also attend Tu Bishvat, Groundhog Day and steal the show in an elaborate production of the Nativity. TV personality and fashion designer Whitney Port is on hand to help them through the festive maze.
