On Lyoko, Antea, Sven-Søren and Rumiko were already making their way to the activated tower. Dennis had sent them into the Mountain sector and was already trying to find XANA's location on Earth.

"Great." He said sarcastically.

"Problem, Dennis?" Rumiko asked.

"I still can't find what XANA's up to." Dennis said. "I texted Sam not too long ago, but still no response."

"Well, give it time." Antea said. "They are in a museum you know."

"But that's the thing." Dennis said. "Calvin called earlier saying that he kinda figured… Oh great."

"What?" Sven-Søren asked.

"XANA's at the museum." Dennis said. He then looked back on his map to find anything suspicious. "Then how come the map isn't showing anything."

"Calvin, wherever you are, you better be alright." Antea said as they continued to proceed on foot.

Back at the museum, Calvin got up after being knocked to the ground by William Jr.

"Alright." Calvin said. "Let's get this over with."

"Kid, what are you doing?" One of the bystanders shouted to Calvin. "Get out of there before he kills you!"

Calvin didn't listen. He just ran up to William Jr. and delivered a blow that knocked him to the ground.

"You're stronger than I remember." William Jr. said getting up. "I guess that's just a side-effect."

"Side-effect?" Calvin said to himself before he was again knocked down.

"Come on, Cal. Get up." Sam shouted.

"Sam, don't encourage him." Mr. Xavier said. He then turned to Calvin. "Calvin, get out of there before you get yourself killed!"

"No way." Calvin said. "I want to finish this."

"What the heck, Calvin!" Mr. Xavier shouted.

Calvin then ran up to William Jr. and continued to land blow after blow. William Jr. then disappeared in a cloud of smoke and reappeared behind him as he delivered a double axe handle to the back of Calvin's neck as Calvin fell to the ground. Immediately, members of the Unione Corse went up to him and prepared to kill him. But just then, Calvin got up and fought off the Unione Corse members. Using his Pencak Silat training, he was able to fend off his adversaries and dodge their attacks.

"Alright, Calvin!" Sam said as he cheered him on.

When he finished with the thugs, Calvin charged towards William Jr. pinning him to the wall. He then began punching him repeatedly until William Jr. disappeared again.

Back on Lyoko in the Mountain Sector, Antea, Rumiko and Sven-Søren were already heading down the path to the tower when they found themselves ambushed by XANA's monsters and William Jr.

"Dennis." Rumiko said. "Looks like XANA's party has just arrived."

Indeed it has. For just then, a swarm of Hornets and Mantas, along with William Jr. and his black Tarantula, advanced upon the trio of warriors.

"What now?" Antea asked.

"We fight." Sven-Søren said drawing his axe and charging towards the monsters. William Jr. then jumped off his Tarantula and drew his punching dagger as the rest of the monsters charged towards them. Sven-Søren swung his axe at the oncoming monsters and was able to wipe out half the Hornet swarm with a single swipe. William Jr. then ran up to him while Sven-Søren slammed his axe to the ground generating his Enhanced Strength shockwave.

However, while the shockwave stunned the Tarantula, William Jr. jumped up into the air and drew his sword. He then dived down and prepared to attack Sven-Søren. Fortunately, Sven just jumped out of the way causing William Jr. to miss and hit the ground. While William Jr. was getting back up, Antea charged towards him and fired energy field after energy field. William Jr., however, just blocked each of the attacks. He was about to attack back until he felt a sharp pain in his back and fell to the ground. He turned around to find Rumiko making herself visible.

"Miss me?" She asked as she prepared to deliver the final blow. Before she could strike, though, William Jr. just got up and threw her to the ground holding her at knifepoint with his dagger.

"Not really." He said as he prepared to strike. But just then, Antea came up and knocked William Jr. off of her. Antea was then blasted by one of the Mantas and she fell to the ground, stunned but not devirtualized. Sven-Søren, seeing this, immediately broke away from the Hornet swarm and threw his axe at the Manta, destroying it.

"Thanks for that." Antea said to him.

"No p…" Sven-Søren tried to say before he has stabbed in the back by William Jr. and instantly devirtualized.

"You're next." William Jr. said approaching them.

"Antea, make a run for the tower." Dennis said. "Help is on the way." Antea did as she was told as she ran away from the others and towards the tower. Just as William Jr. was about to pursue her, a series of knives came flying out of nowhere and hit the black Tarantula, the last Manta and a few of the Hornets. Most of them even hit William Jr. as he disappeared in a cloud of smoke. Rumiko immediately saw who it was:

"Ami." She said.

"Rumiko, help Antea." She said. "I'll take care of the Hornets."

Back on Earth, William Jr. and Calvin were still fighting at the museum. As Calvin delivered a roundhouse kick towards William Jr. that sent him flying towards the wall, he immediately broke open one of the display cases and pulled out a longsword from it. He then swung the sword at Calvin who dodged it at every opportunity he got. Then, Calvin found himself cornered with William Jr. about to make the strike. However, Calvin grabbed the sword blade with both hands and pulled the sword from William Jr.'s hands. Calvin then looked at his hand and saw that it was bleeding heavily.

"Just a scratch." Calvin said to himself as he tore off part of his sleeve and wrapped it around his hand.

"Calvin, look!" Sam shouted. Calvin turned around to find Unione Corce members taking the uranium ore and placing it in a large container.

"Forget it, Calvin." Mr. Xavier said. "The Return to the Past will fix everything anyway."

Back on Lyoko, Antea could already see the tower in front of her. Just then, she found two Tarantulas blocking the way and firing at her. As she hid behind a rock for cover, Rumiko came up and threw her sai at the Tarantulas wounding one and killing the other.

"I got it from here." Rumiko said. "Go now!"Antea then headed inside the tower and proceeded to deactivate it. She then reached the platform and entered CODE: LYOKO.

Back on Earth, William Jr. fell to the ground as he felt himself begin to disappear. However, he just chuckled.

"You lose, Calvin." He said disappearing."You lose." Just then, a bright light came out of nowhere and enveloped the museum.

"Return to the Past, now." Dennis said.

At the museum, everything was fixed and everyone was acting as if nothing happened, with the exception of Calvin, Sam and Mr. Xavier who were unaffected by the return trip.

"Well, now that that's out of the way, let's get back before…" Mr. Xavier started to say.

"Oh no!" Gilbert shouted. "The uranium! It's gone!" Indeed it was. For the glass case that contained it is now empty.

"Impossible." Calvin said shocked. "The return trip should have brought it back."

"You didn't see anything suspicious, did you?" Gilbert said to the three.

"We better leave before things get more out of hand." Sam said.

"Gotcha." Mr. Xavier said as they headed out leaving them confused about what had happened.

Well, due to end of the year stuff, I may end up postponing both stories until my summer break starts (June 15th), but after that, it'll be smooth sailing once again. I might fit another chapter in; we'll see how things go.

Please Review.
