The Enfield Haunting (2015)
S04E02 Double Take
Episode Overview
To make up for William's absence while he's under XANA's influence, Jeremie focuses on creating new gear for his friends and reconstructing Lyoko. To buy himself some time, he activates a tower and generates a clone to attend classes on his behalf. However, William's disappearance raises eyebrows from both the principal and his father. While Jeremie's clone impresses Jim, William surfaces in Lyoko, attempting to take control of the tower for XANA. Jeremie taps into Sector Five for energy to keep the tower active but soon depletes his resources, allowing XANA to seize control. As Odd distracts the clone, Aelita, Yumi, and Ulrich enter Lyoko equipped with new abilities. They manage to deactivate the tower and confront William, who tries to push Yumi into the digital sea, but Odd saves her just in time. Jeremie then rewinds time and swaps his clone with a William clone to avoid any suspicions about William's whereabouts.
