Code Lyoko Episode 7 – Image Problem Episode Title:Image Problem.Episode Description:After an unexplained incident on Lyoko ends up devirtualizing Yumi without any cause, she is taken to the infirmary. After waking up, she attacks the nurse, Yolanda (addressed as "Dorothy" in the English dub), and continues to act strangely throughout the day, wanting to go to Lyoko with everyone else. Jeremy will not let them, though, because he wants to know what caused her devirtualization. Meanwhile, on Lyoko, Aelita finds several Kankrelats guarding an orange sphere, which she calls a Guardian, and informs Jeremy. Back at the school, Principal Delmas confronts Yumi about her attack on Yolanda. When he threatens to call her parents, she attacks him as well. In another attempt to get the group to Lyoko, Yumi tries to seduce Jeremy to convince him to arrange a mission. She fails, but Odd and Ulrich stumble upon the scene. Jeremy tries to explain, leaving Yumi alone. Jeremy apologizes for the incident, citing Yumi's strange behavior. When they head back to his room, they find his computer destroyed. Yumi seems the likely culprit. She shows up to meet them, still wanting to go to Lyoko. Having no choice, they go, but Yumi stops the scanner before it can close, leaving her alone in the scanner room. As she goes to work destroying the scanners, the others find the real Yumi trapped inside the Guardian. After being devirtualized by Ulrich, she and her clone engage in battle. Eventually, the clone tries to kill Jeremy, but Aelita manages to deactivate the tower before Jeremy falls to his death.
