Code Lyoko Season 4 Episode 18

Hard Luck

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 xana - her father is just a mirage, and William is there waiting for her to throw Aelita in the digital sea Williams say(impossible to escape this bubble as it is your prison) 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 if she's gone, she is lifted from the sea by the real Franz Hopper, who has manifested himself as a floating blue bubble with a pink aura. After dropping her back on Lyoko, he returns to the digital sea.
