After being teleported to the supercomputer, Yumi, Aelita, Ulrich and Odd were confused.
"Let's get this over with." Ulrich sighed as he stabbed the supercomputer with his katana.
Just then, the lights came back on, went out, and came back on.
"Jeremy, the power went out then came back on. Does the school have a backup generator?" Yumi pondered.
In a previous mission, Yumi remembered the same thing happening as the facility had an emergency generator. (See Code Lyoko Episode 79 "Bragging Rights").
"It seems the backup power generator is in the supercomputer itself. You'll have to damage it one more time." Jeremy announced.
However, as everyone banded together to destroy the evil being 'asleep' in the supercomputer, the door opened to reveal Ralph walking into the room.
"Einstein, we've got a problem." Odd panicked.
"What is it?" Jeremy wondered.
"You know that kid we let on Lyoko?"
Yeah, what about him?"
"He's here."
"He what!? This is bad! That means he probably remembered the supercomputer and he'll tell the nearest adult what you guys are doing! I'll send you back to-"
"No! We're not giving up! Not when we're so close to defeating Xana!" Ulrich interjected.
"You have no choice but to retreat!" Jeremy yelled.
"This is it, you've given us enough grief Xana! Say goodbye!" Ulrich shouted as he stabbed the supercomputer.
Yumi slashed the supercomputer by throwing her fan, Aelita threw an Energy Field and Odd shot a Laser Arrow. As the computer short circuited, the life of it and Xana ended with a 'bzzt'.
"I, I can't believe it." Yumi whispered.
"Is it all over?" Aelita wondered.
"It sure is! I can't believe it! Guys, Xana's gone for good! I'll devirtualize all of you now." Jeremy cheered.
The others were all devirtualized.
"Nobody will believe that kid will they? I mean, nobody ever believes kids anyways." Ulrich doubted.
"That's the most likely case." Jeremy assured.
As soon as she noticed Caltech, Paige felt a peculiar urge to inspect the building in hopes of finding her missing child. Not ignoring her motherly instincts for a second, Paige parked the car in a staff parking space -regardless of the possible consequences- and barged into the building without the slightest hint of hesitation. Unfortunately, there wasn't any light for her to seach by. Luckily, Paige remembered her fully charged phone and removed it from her pocket in hopes of shedding a little light onto the situation (pun intended).
After using her phone to search the grounds, Paige walked by a suspicious sight, the door to the campus basement was open in the main building. Wondering if anyone was stuck or lost in the basement when the power went out, Paige walked forward to look in the basement. Suddenly, a startling sound of muttering reached Paige's ear.
"This is where Walter said he went with mom to go back to college. Why am I here?"
Paige instantly recognized it as her son and began to run down the stairs as fast as she could without tripping.
"Ralph sweetie? Where are you? Are you okay?" Paige worried.
"I'm here mom!" Ralph hollered.
Paige shined her phone light to where she heard his voice and sure enough, Ralph was standing in front of the damaged supercomputer. Curious about both the damage and the ones who inflicted it upon the innocent machine. In that moment however, Ralph threw aside his curiosities in exchange for the safe and loving warmth abundant in his mother's arms. Within her hugs, Ralph found a sense of security, comfort, tranquility and peace unlike anything else.
"What are you doing here?" Paige interrogated.
"I don't know, I just woke up here. And I saw some people damage the computer, they were wearing weird outfits and seemed to dissapear in the blink of an eye." Ralph responded.
"It was probably just a bad dream sweetheart, let's get you back to bed."
It was then that Paige remembered she needed to call Walter and notify him that Ralph was safe.
"Hello?" Walter greeted.
"I found Ralph." Paige smiled.
"That's a relief, where was he?"
"In Caltech's basement near the supercomputer."
"I'm heading back to the garage then, I'm glad he's alright."
"Me too, goodnight."
"Night."
As she was driving home with her son in the front passenger seat, it reminded Paige how grown up he was.
When the return to the past activated, there was a sunny and happy day ahead for all. With no fear of Xana or the men in black, the Lyoko Warriors were eager for the joyous times ahead.
