Double Take is the second episode of Season 4 and the 67th episode of Code Lyoko.


Jeremie creates a polymorphic spectre of himself to go to Phys. Ed class in order to be left to work undistracted on bringing William back from Lyoko and free of XANA's control. Jeremie’s body double turns out to be far more athletic than the original, to Jim’s considerable surprise. But XANA gains control of the tower Jeremie used to conjure up his clone, and the imposter now poses a serious threat to our heroes. A battle ensues on the now fully reconstructed Lyoko, featuring new, updated gear for the Lyoko Warriors.


  • The original French name for this episode is Mauvaise réplique.
  • This is the only season 4 episode that Ulrich uses triplicate.
  • This is the first time seeing a Lyoko Warrior with their new outfit.
  • At the end of the episode, the tower operating William's clone is shown inside a crater, but in every subsequent episode the tower had been seen in, it has been seen near the edge of a plateau. Likely an error or Jeremie had to change the tower for security reasons.
  • The name and the attack itself is a reference to the episode Double Trouble
