Code Lyoko S4 E16

## Plot

During lunch, William's clone imitates one of Odd's stunts, and Jim makes sure he gets in trouble. Jeremie is concerned by this, because the clone is a polymorphic specter. It shouldn't be capable of evolving. Yesterday, he updated the clone's software to improve his artificial intelligence, to make him seem less stupid, like in the previous episode. He also upgraded the superscan to have it find other replicas. If they destroy them all, they'll finally get rid of XANA for good. He found a second one. Aelita feels bad for William's clone, because she thinks she's the reason he's in trouble in the first place, because she also tried to imitate Odd, and failed spectacularly. Also, she might feel like she's the reason he's necessary, since she and William were alone in Sector 5 when they encountered the Scyphozoa. Jeremie reminds her that he's an artificial intelligence. She reminds him that she was a short time ago too, but he says that's different. An artificial clone doesn't have feelings. It turns out that Milly and Tamiya overheard them. They enter the second replica, which is an exact copy of the Desert Sector. Milly and Tamiya question William's clone. Milly claims that she wrote him a love letter, and he says he didn't get it, so it must've been William. Yumi and Odd will guard the Skid while Ulrich and Aelita teleport to Earth. They're at an abandoned military base in New Mexico. The clone tells Milly and Tamiya that XANA captured William. Milly asks for proof that he's telling the truth. He says he can ask Jeremie to show them some in the computer lab at the factory. Yumi and Odd fight Hornets. The real William comes out of the scanner. Instead of going up to the lab, he heads down to the supercomputer. He came to destroy it. Ulrich and Aelita see an assembly line of machines creating computer chips. Yumi and Odd fight Tarantulas. Jeremie confronts William. Aelita is worried about him, and wants to abandon the mission. Suddenly, Milly, Tamiya, and clone William see Jeremie and the real William. The clone tackles the real one. Jeremie hurt his foot, and can't walk. He tells Milly and Tamiya to get to the computer lab and tell the others to get back, and quickly. Tamiya enters the lab. She tells everyone what Jeremie told her. Ulrich and Aelita devirtualize each other, and are sent back to the Skid. The clone sends the real William up to the computer lab. Jeremie says he can still do a lot of harm, and tells the clone to go through the trapdoor and stop him. Yumi is devirtualized, and Odd is teleported back to the Skid. The real William knocks Tamiya back and does something to the scanners. The clone comes in, but William shuts down his tower, and he disappears. Jeremie says that the cooling chamber is overheating, and the supercomputer will reach a combustible critical mass. He tells Milly to stop William. The others are attacked by new creatures called sharks. How creative. Yumi is finally able to pry the scanner open, and she gets out before it closes again. The others get back and devirtualize themselves. Milly confronts William. He sets up a delayed virtualization for himself, and heads back down through the trap door. The others ride the elevator up. Aelita fixes the cooling system. They tell Milly and Tamiya everything, like how they've been fighting XANA for around two years now, and then they do an RTTP. Man, it's been awhile since they've done that. This time, Jeremie decides to delete the old upgrade program and create a new one from scratch. He tells the others that when he created the clone, he used some programs that were already in the supercomputer. They were created by Franz Hopper, but he also thinks they were some of the same programs that developed the personality of XANA.
