Three months after the first battle for humanity, XANA returns to enact his next plot. Though weakened by the devastating attack on him, he is nevertheless just as persistent with achieving his goals. Having tricked William Jr. into serving him and carrying out every step of his plan, the Lyoko Warriors now face two major adversaries. Other things to expect are a bugged program, a devastating virus, a changed personality, breakups, betrayal, false accusations, and an unexpected ally.

(A/N: Continued from Chapter 3 of 100 Days)

Last Time:

"What's going on? Who is...?" Calvin said before he was knocked to the wall and pinned down. He then looked up and saw a punching dagger held to his throat. He then saw the wielder of the dagger and was left in complete shock.

"Hello, Brother." William Jr. said.

"William Jr.?" Calvin asked surprised.

"Yes. Surprised to see me?" He said still holding the dagger up to Calvin's throat.

"What are you doing?" Calvin said before he felt the dagger plunged through his neck and was immediately devirtualized.

"Sorry, but it's XANA's orders." William Jr. said. Just then Rumiko and Sven-Søren ran up to him, but William Jr. took them out with two swings of his daggers. He then went for Antea and Sam; he hit Antea but Sam just jumped out of the way, shooting laser arrow after laser arrow at him. However, one of the shots was deflected back at Sam and he fell to the ground. William Jr. just plunged his daggers into Sam, devirtualizing him. He then went to Ami.

"Willy, please." She said. "Why are you doing this?"

"XANA was very specific." He said. "Kill the Lyoko Warriors, and he brings my brother back."

"What?" Ami said. "You made a deal with XANA?"

"I had to." He said. "For Russell."

"You're insane." She said. "Besides, how do you plan to kill us yourselves if you're stuck here?"

"I'll find a way." He said stabbing her and devirtualizing her. He just gave a wicked smile and disappeared.

Back in the scanner room, the doors on one of the scanners opened and Ami just climbed out. She then saw the other and went to them.

"What just happened?" Sam asked.

"I tell you what happened." Ami said. "William Jr. betrayed us."

"Well that figures." Antea said. "First his father's forced to become XANA's slave now William Jr..."

"He wasn't forced." Ami said. "He willingly joined his side."

"Really?" Rumiko asked.

"Yeah, I could see it in his eyes." Calvin said. "Literately as well as metaphorically."

"Yeah, you're so funny, little brother." Rumiko said sarcastically. "This is no time for jokes. Even if we bring him back, he'll still try to destroy us."

"And he won't stop until were dead." Sven-Søren said.

"Wait." Sam said. "If he wanted to kill us, why didn't he just throw us in the Digital Sea?"

"The ANAX Program." Calvin said. "If it saved me in less than a minute after being dead for five minutes, he'll probably save you in that amount of time as well."

"Duly noted." Sam said.

"Sam, do you even know what that means?" Calvin asked.

"Yeeaaa... No." He said. "Now let's go. School starts in a few minutes."

Within a few minutes, they arrived at Kadic Academy and they went to their respective classes. Sam and Calvin had Mr. Xavier's class again for first period.

"Alright class." He said. "Today you will get another quiz based on what will be taught this year. Calvin, you are exempt from this quiz since you already passed it the first year and I don't want to take any chances."

"Yes sir." Calvin said.

"How was your summer by the way?" He asked

"It's was okay. Some sadness, some gladness." Calvin said. "Pretty eventful to say the least."

"I see." He said. "Did the new guys visit you-know-where yet?"

"Yes." Calvin said. "And Dennis's brother made a deal with you-know-who and won't stop until he finally kills us."

"Oh dear." Mr. Xavier said. "Well, I'd love to help you out, but I already did plenty with you last year and I'll be devoting most of my time towards teaching. So you're on your own, I'm afraid."

"Very well." Calvin said. "Mom and Dad promised they'd help out once in a while anyway."

"Glad to hear that." Mr. Xavier said. "Well, we'll talk more later. I have a class to teach."

After the next few classes, everyone went to the cafeteria for lunch. They then noticed a familiar face at one of the tables.

"Dennis?" Rumiko asked.

"The one and only." He said.

"What are you doing here?" Calvin asked. "I thought you were in college?"

"I got a part time job here so I can build myself a resume and give me a better chance when applying." He said. "Also, so I participate more on Lyoko missions."

"So what are you doing?" Sam asked.

"I'm the assistant coach for the soccer team." He said. "Once this year's over, I'll start applying for colleges."

"Sounds nice." Calvin said.

"Is something on your mind?" Dennis asked.

"Well..." Calvin said. He and the others than told him about how William Jr. joined XANA because of the deal he made about bringing back Russell.

"So, Willy's trying to kill you all?" Dennis asked. "I guess that's what happens when you get possessed by XANA."

"But that's the thing." Calvin said. "He wasn't possessed, he was deceived by a false deal. Even if he kills us, XANA won't keep his promise."

"That is bad." Dennis said. "So what do we do now?"

"We fight William Jr. and try to convince him that XANA's lying. Once he realizes this, then we bring him back."

"I just hope it's easier done than said." Dennis said.

"Well, were not giving up." Rumiko said. "Besides, XANA himself is weak. What else could go wrong?"

Unknown to them, however, the worst was yet to come.

Well, you wanted it, you got it. The sequel is now up and running. I'll try to update this as often as I do with 100 Days, but I'm not making any promises. Also, thanks to Commacazy Freak for coming up with the title.
