She only tells him once she gets to Lyoko, so he can't object. She begins to transfer her own genetic code to Yumi, which will let Xana take her memory at will, being exposed.

Having no other choice, Jeremie decides to test out an experiment which will give a person the same powers as one possessed by Xana. To do this, he has to activate a tower like Xana. Jeremie's towers turn green instead of red. Odd volunteers, and is enhanced by a ghost of Jeremie's design. This allows Odd to fight the nurse effectively while the others deactivate the tower. This fortune doesn't last, however. Xana is able to take over Jeremie's tower, reversing the effect of the ghost to drain Odd's energy. And on Lyoko, Xana makes everything invisible. Now the group has to deactivate not only the original tower, but the tower that's draining Odd's energy. - Franz Hopper

However, when they arrive at the factory, they find a man at the interface, deactivating the towers as if it were a simple matter to do so. When questioned, the man claims that he's none other than Franz Hopper. However, something seems off about this convenient arrival. Franz says that the scanners cause cell degeneration, and blames it and the destruction of his diary on Jeremie. With everyone except Aelita angry at him, Jeremie calls his father and asks to be withdrawn from Kadic in favor of a school for gifted students – but after he hangs up, while pondering his dilemma, he realizes that there is something inherently wrong with Franz's explanation. - Contact

Later on, she walks into Jeremie's room and writes some code on a piece of paper. Jeremie 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. Xana isn't 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 Xana succeeds in shutting down the white tower. After Xana's tower is shut down, Jeremie translates the message, revealing that Franz Hopper had activated the white tower. - The Key
