Episode Title:
William Returns.
Episode Description:
Using the data that Franz Hopper gave them, Jeremy and Aelita succeed in recreating Lyoko, which now holds only Sector 5. Soon after, William is materialized, and seems perfectly normal. He shows up at school much to Yumi's delight and Ulrich's disdain. Sissi decides to make herself "editor-in-chief" of Kadic News, much to Milly and Tamiya's dismay. She soon barges into Aelita's room to interview her and is stopped by William. As soon as William makes Sissi, Tamiya and Milly leave, he kidnaps Aelita and takes her to Lyoko. William leads Aelita out of Sector 5 and to what used to be the Desert Sector. His intent is revealed to throw Aelita into the Digital Sea. Odd manages to stop him, but William dives into the Digital Sea. Jeremy concludes that this is X.A.N.A.'s new strategy and that they must be very careful.
