Code Lyoko Episode 50 - Contact Episode Title:Contact.Episode Description:During a short film made by Odd and starring Sissi, Sissi seems to be possessed by a ghost. She does not act as expected, however. Instead, she starts speaking in an unknown language, focusing on Jeremy as she does. She is taken to the infirmary as a result. Later on, she walks into Jeremy's room and writes some code on a piece of paper. Jeremy translates the code, revealing a message stating a desire to help. Sissi is sent to the hospital after this, forcing Odd and Yumi to go there and collect her. On a trip to Lyoko, Aelita and Ulrich discover a white tower. X.A.N.A. is not happy about the tower, and sends Megatanks to shut it down forcibly. At the same time, it activates a tower and possesses a nurse at the hospital to do the same to Sissi. Odd and Yumi are able to prevent the nurse from doing so. They bring Sissi to the factory to finish the message she started earlier. She manages to type most of it out before X.A.N.A. succeeds in shutting down the white tower. After X.A.N.A.'s tower is shut down, Jeremy translates the message, revealing that Franz Hopper has activated the white tower.
