Overview:It's holiday time at Kadic and everyone is headed home. Aelita, however, has no home to go to. As she watches over Lyoko, she gets a message from Franz Hopper, who has constructed a simulation bubble of their mountain home on Lyoko. Though happy to see her father, Aelita quickly learns that the entire thing is a trick from X.A.N.A. – her father is just an illusion in the simulation bubble on Lyoko. William is there waiting for her in order to throw her in the Digital Sea. However, she escapes resulting in William chasing after her. The rest of the group, having been unable to contact Aelita, follows her onto Lyoko, but they fail to keep William from throwing her into the Digital Sea. When it seems as though Aelita is gone for good, she is lifted from the sea by the real Franz Hopper, who has manifested himself as a floating white bubble with a pink aura. After dropping her back on Lyoko, he returns to the Digital Sea.
