Cody returns for Total Drama World Tour with hopes that he can try to win over Gwen, especially now that she and Trent had broken up, but he is also put on the receiving end of an attraction by his biggest fan, Sierra. Before they even leave the airport, Sierra is shown to know what his full name and his birthday were, even though this information had never been revealed on the show. While he generally tries to avoid Sierra for much of the season, the two are often paired up for the challenges.
