Episode 1: Aelita enemy, Xana Ally?
"ATTACK!" Aelita yelled at some pink blocks, and they follow the order.
"JEREMIE! WE NEED A LITTLE HELP!" Ulrich yelled at the sky.
"I know, I know, I can't do a thing!" Jeremie yelled back.
"But I can." Said a figure that looks like William, minis the sword. William was standing next to him; he was about 2 or 3 meters taller. The taller William pulled up an interface, and then some blocks appeared, "FIRE AT THE PINK BLOCKS!" he yelled, and they did.
"XANA!" Aelita yelled from top of her pink manta.
"yes." The figure, apparently Xana said. And his blocks were finishing Aelita's.
"Come on." Aelita muttered to herself, and she pulled up an interface, and Megatanks appeared, looking no different than Xana's, but when they opened, the symbols where that of Aelita's (that's but with an "A" instead of the dot) "FIRE!" the newly created Megatanks did as ordered, quickly destroying Xana's Blocks.
"Alright, I will play your little game." He said, summoning Megatanks of his own. "FIRE!" they opened and did as told, but Aelita's Megatanks closed, and were only pushed back into a rock, when it was safe, they opened and fired, the same thing happening with Xana's Megatanks.
The Lyoko Warriors were behind a rock, watching the battle.
"Hurry! Mary! Get to the tower!" Ulrich said urgently to a pink haired girl that looks like Aelita did before Xana Destroyed the core.
"OK," she said, then ran for the tower, getting in safely.
"Oh well," Aelita said, feeling Mary enter the tower, "not like it was super important, see ya later Xana, Warriors," and with that, she, and all of her monsters, disappear.
Mary gets to the second platform and puts her hand on the interface

She walks out and she and the Warriors talk to Xana.
"Why did you help us?" Ulrich asked.
"Ever hear the phrase, "the enemy of my enemy is my friend?" He asked.
"Yes," Ulrich said, "but that doesn't explain why you helped us."
"Aelita is a bigger threat to me than you are, and I need help."
"Help us get Aelita back." Jeremie said.
"I will." Xana replied.
"Then it's a deal." Jeremie said.
"WHAT!" all the warriors said, surprised that Jeremie trusts Xana that easily.
"OK, go back and I will keep an eye out." Xana said.
"Ok…" Ulrich said, not completely trusting Xana yet.
Jeremie brings them in and they all go back to Kadic.
The next day at lunch
BEEP! BEEP! BEEP!
"What the?" Jeremie said, getting his laptop out, and seeing a video chat with Xana. "What Xana?"
"We have problem."
"What?"
"Aelita is taking over my replicas!"
"WHAT!" Everyone said when they heard this.
BEEP! BEEP! BEEP!
A new video chat window pops up, With Aelita in it.
"Hello Jeremie." She said
"What do you want?" Xana said bitterly, Look towards the other chat window on the laptop.
"I want to tell you guys what I'm up to." She replied.
"What are you up to?" everyone asked her.
"Someone foolishly sent a message to someone over an unsecure network, and unencrypted, and it said the sender want the receiver to spy on you guys and report back, but, the from and to addresses were encrypted from some reason, I am trying to locate the future spy, and tell you who it is." she answered.
"And you expect us to believe that?" Xana asked.
"Not really." She replied. A soft beep can be heard in the background "looks like I have enough power to locate the spy. See ya later." And with that, the window closes.
Everyone looks at each other, wondering if she told the trust.
