Jeremie told me that if one of the Lyoko Warriors was devirtualized with his sword (he moved the program from my sword to his) that they would be free from Xana's control. But before the angel fell, the strangest thing happened.
Jeremie: I hate having to do this, but you leave me no choice. (Jeremie slashes through Xana-Aelita at her shoulder at the same time William strikes her in the back, she devirtualizes in red pixels, screaming)
William: What the heck just happened?
Jeremie: Did it work?
William: Only one way to find out. Return to the lab, I'll handle these guys. (Jeremie devirtualizes himself with his sword and disappears)
After that, I was left to face the remaining three Xana Warriors with no assistance from Einstein. But because of this situation, this war against Xana, I was starting to believe I had to handle everything all by myself.
(William uses his sword and deflects Xana-Odd's laser arrows, he kicks Xana-Odd down but he gets up and charges at William, kicking him in the face and knocking him down, William gets up, grabs his sword and devirtualizes Xana-Odd in red pixels, Xana-Ulrich punches him in the face and knocks him into a way tower)
William: Ok, this isn't working... (Xana-Yumi follows him, he turns around and sees her smiling evilly, she then pushes him off the platform, he grabs her wrist, they dive into the data stream)
I wasn't sure what was going on at first, but I soon found myself in the Desert Sector. I learned that way towers could be used for getting to any other sector on Lyoko, with the exception of Sector 5. I quickly learned that Xana-Ulrich followed me. Now I had to fight both of them.
(Xana-Ulrich uses Super Sprint to reach William, he charges his sword with an energy wave and when Xana-Ulrich and Xana-Yumi get near him, he sends Xana-Ulrich falling towards the Digital Sea and Yumi nearly falls in, but she regains her balance and throws one of her fans at William)
Xana-Yumi: You are a fool, William. Do you really think you can defeat Xana?
To be honest, I didn't think I could defeat Xana, but I had to at least try.
(William swings his sword at Xana-Yumi, only for her to somersault and dodge his moves, he throws an energy wave at Xana-Yumi with his sword, but she deflects it with her fans, she throws her fans back at him, he back-flips and finds himself close to the edge of the Desert Sector, he looks at the Digital Sea below him, Xana-Yumi walks towards him)
I knew that if any warrior under Xana's control fell into the Digital Sea (such as Ulrich for example) they would be safe. But if I fell in, I'd be lost forever. Under Xana's control, Yumi cornered me and I was dangerously close to death...
Xana-Yumi: Looks like you're you're going to die, pretty boy. Any last words? (she pulls out her fans, William holds up his sword)
William: I'm sorry, Yumi. (he closes his eyes and Xana-Yumi screams, he opens them and he sees Xana-Yumi disappearing for a second, he then drops his sword)
I couldn't bear to see Yumi disappear before my eyes, so I closed my eyes, held up my sword and devirtualized her. I softly cried until I heard a familiar voice bring me back to reality.
Jeremie (off-screen): William? Are you ok? (he looks up)
William: I'm fine. I defeated the other Xana-Warriors. Did it work? Is Aelita back and free from Xana's control?
Jeremie (off-screen): She is. I'll bring you back in so you can see her.
I was brought back to Earth and I meet Jeremie and Aelita in the lab. I told them of my visions with Aelita and Franz Hopper. Jeremie and Aelita were rather shocked.
Jeremie: Wow. It looks like you may know more about Aelita's father than we do.
Aelita: Jeremie, do you think there's still a way to save him?
Jeremie: I think there is a way, but the idea I have in mind is rather... complicated. I'm not even sure if it's possible.
William: What is that idea?
Jeremie: I can tell you later. It's been a long day.
I went up the elevator and decided to be alone on the ground floor of the Factory. I was still upset about having to devirtualize Yumi, but I didn't want the others to see it.
