The Enfield Haunting (2015)

S1E7 Image Problem

The episode kicks off with Yumi and Aelita sprinting through Lyoko in search of the active tower. Suddenly, Yumi vanishes! She materializes back in the real world, looking exhausted yet perfectly fine. When she enters Jeremy's room, she removes his glasses and gazes deeply into his eyes, leaving Odd and Ulrich stunned. Jeremy quickly realizes that Yumi is under Xana's control. Shortly after, Odd, Ulrich, and a seemingly possessed Yumi are digitized. Yumi manages to break free and attempts to wreak havoc at the factory. Eventually, they discover the "real" Yumi trapped in an orb, and they eliminate the corrupted version, bringing the episode to a close.
