Video : Madame Einstein

A new girl-genius and highly gifted teenage girl named Laura Gauthier tries to join the quintet at Kadic Academy. She humiliates Jeremy by correcting his mistakes on a complex exercise in class. Aelita suddenly is resentful and suspicious of this new girl, who seems to want to discover their secret.

Meanwhile, Jeremy informs his four friends that he has programmed a new vehicle that is made for travelling through the Cortex easily called the Megapod. Once on the Cortex, they are impressed by the new cruiser, which Yumi ends up driving. Unfortunately, Laura follows William to the factory and discovers the lab and Supercomputer, which she is very interested in. During a battle with several Krabes, Aelita, Odd and Ulrich are devirtualized, leaving Yumi trapped in the Megapod. With Laura's help, Jeremy fixes the bugged vehicle and Yumi is returned to Earth just before the Megapod falls into the Digital Sea.

Back in the lab, the team debate about whether they should accept Laura into their group. Aelita, however, is still resentful and distrustful of Laura, and launches a return to the past so that she will not remember anything.
