The Other Aelita
It's Saturday, Odd is happy because there are meatloaf and believes that this is the best food. The Lyoko-Warriors come into the cafeteria where they have a meeting with Sissi's clone. Nicolas and Herb approach and try to talk to Sissi's clone, but Ulrich says now she isn't her friend, and Nicolas and Herb leaves. Later in the rec room, they are doing a table-tennis competition Odd against Jim, and the teacher wins. In the night, starts making abnormal cold, but everyone says it's because of the weather. And it rains all night, and Yumi suspects something.
The next morning, Sunday, we all wake up and discover that there is a hailstorm. In the cafeteria again, Jeremy's laptop starts ringing: it turns out that X.A.N.A. has activated a tower in the mountain sector and has launched an attack creating the hailstorm. Aelita, Jeremy and Yumi react quickly escaping except for Odd and Ulrich were arguing. These are trapped in the room by the hailstorm. Odd tries to go to the Tactory, and Ulrich stays at Kadic with the other students. Jeremy virtualizes Aelita, Yumi and Odd in the mountains of Lyoko.
In Kadic, starts falling hailstones of small to giant sand stones and other materials, and the Eye of X.A.N.A. appears in the sky. Ulrich knows what it is, and tries to call the other but there isn't coverage because of large hailstorm. In Lyoko, three Megatanks and X.A.N.A.-Sissi appear to prevent deactivate the tower. A Megatank shoots to Odd, but he uses first successful teleportation and goes to a plateau, causing the destruction of another Megatank. But appear more Megatanks. In Kadic, things get complicated: all is full of rocks, and are damaging the structure of the buildings and other things out there. Jim tries to call the police, but the hail is only on Kadic and in the center of Paris is sunny, and the police don't believe him.
On Lyoko, Odd fight against Megatanks while Yumi is fighting X.A.N.A.-Sissi. After a great struggle, X.A.N.A.-Sissi wins but Odd devirtualizes her. The two Megatanks devirtualize Odd but Aelita destroys them with an energy field. In Kadic the situation gets worse, the roof begins to aboyarse. In Lyoko more Megatanks appear, but Aelita enters the tower and is deactivated. After the great destruction, the hail Kadic disappears as if by magic, and to repair the damage, they return to the past.
It's Saturday again, and Jeremy tells Odd that Teleportation worked successfully. Jeremy says he now has to work to finish the Skid, and most importantly: recover Sissi. This time there aren't bad weather. The next day, Sunday, Odd makes another game of table-tennis with Jim and Odd wins.
