Jack Frost flew north, knowing exactly where to find the Guardian of Wonder in any dimension. With the wind helping him, it did not take him long to reach the place where North's workshop could be. What Jack found there, stunned him. Where the workshop should have been was nothing but rubble, pieces of wood scattered across the ground revealing a building that no longer even existed. "No, this can't be!" Jack yelled out, getting frustrated. If the building was destroyed, that meant belief in North was gone. Children had lost belief here already. Thinking back to the crown he saw on A/D Pitch's head, Jack realized that in this world, Pitch had already won. The Guardians weren't here and children didn't have hope, wonder, and dreams anymore.

Not wanting to believe that it is true yet, Jack flew off once more, in search of the one child he knows will always believe in his world. Jamie Bennet was a good kid, one that believed in all things magical except for Jack Frost it seemed. In this world, Jamie had to believe in at least one Guardian. Jack could not even imagine a version of the kid that didn't believe. As he arrived in Burgess, Jack found the house that resembled Jamie's house from his world. Just like Danville, this city had changed with the new dimension, ruled over by Doofenshmirtz just like the other town. While it was slightly disturbing to see all the posters of the man everywhere, Jack was more concerned with the young child inside the house he was hovering next to.

Inside, Jamie Bennet was awake and feeling depressed. He had tried for so long to get some sort of proof that the Easter Bunny or Santa existed, but no proof came. When he stopped getting money under his pillow for every tooth and when Easter didn't come that year, Jamie hadn't been able to keep believing. He tried to make excuses to his friends, but it only resulted in being picked on and abandoned by them. Now that he had given up on magical beings, his friends were long gone and he was alone. Nightmares came to him every night and the only magical being he believed in anymore was the boogieman.

Jamie was sitting on the edge of his bed, holding his head in his hands to recover from the nightmare. Typically, he struggled with remembering the details of his dreams but this one left him feeling terrified. He could still remember the feeling of falling of that cliff, rushing towards the hard ground below. Jamie had woken up just moments before he hit the ground, but that did not change the fear that was rooted deep inside of him as a result of that dream. He was too distracted by his misery to even notice the frost building up on his window.

Jack Frost had never seen Jamie look so depressed, so…afraid. He knew immediately that something was wrong with the kid, just from the expression on his face. Jack let the truth settle in now, the truth that the Guardians were gone and no kid believed. If this kid had no hope, than no child left would believe in the Guardians. "No…Jamie, please don't give up." Jack whispered, gently touching the window and accidentally frosting it over. He pulled his hand back, hesitating before flying into the room to get closer to the kid.

"I'm all alone. They left me and now, we aren't allowed to play together." Jamie cried, his mind going back to his old friends. Things might be better if he had someone to talk to, but with the new laws and their new opinions of Jamie, that time never came.

"Hey, I'm right here, Jamie! Just look at me!" Jack pleaded, walking over to the kid and trying to get his attention. Just like back home, Jack Frost didn't have any luck. It seemed like he didn't have belief over here either, that Pitch was the only one children saw. Glancing back towards the frost on the window, Jack decided to try something new.

"You don't believe in the Guardians, huh? Well, I'm gonna show you how wrong you are." Jack told him, grinning as he began drawing in the frost. First, a small egg to represent Easter itself, something that would make Bunny roll his eyes if he were watching. Glancing back, Jack realized that he had the kid's attention now.

"Wha-is that an egg?" Jamie whispered, getting up slowly and staring at his window. Jack continued, drawing a cute little rabbit, more like a pet bunny than Bunny himself. It would be so funny if this was what Jamie was expecting to see when he met the real Easter Bunny. Jack couldn't wait to see the look on the kangaroo's face from this world.

"Now a rabbit? No…a bunny. The Easter Bunny?" Jamie whispered, gasping as it suddenly came to life and began flying around the room. He laughed quietly, trying to stay quiet as he chased the bunny around the room. This was the best thing that had happened to him in months. He was not going to waste this opportunity to have some fun and recover from his nightmares. As soon as he touched the bunny, it exploded into snow around him. When one of the flakes landed on his nose, he began to remember a familiar phrase his mother used to tell him before going outside.

"Jack Frost." he whispered, beginning to realize that that boy was real, that maybe all of them had been real this whole time. Jack froze, unable to believe what he had heard. No one believed in him, not at home and he was certain no one would believe in him here.

"Wait…did you just say…" Jack was about to ask, before Jamie interrupted him again.

"Jack Frost!" Jamie said, this time with more enthusiasm. He had turned around and now, he could see the white-haired boy standing in his room. Jamie could not believe it and if it was a dream, he never wanted to wake up from it. He wanted his belief back, the belief that all things could be magical in this world and not just terrifying.

"But..that's me! Can you see me?" Jack asked, watching Jamie nod. He was backing up now, getting more and more excited. It didn't matter if this wasn't his Jamie, it was still a child that could finally see him. "Can you hear me?" he asked, clarifying once more. When Jamie nodded again, Jack couldn't help but flip through the air, landing on the ground once more.

"You just made it snow, in my room!" Jamie claimed, getting almost as excited as Jack. The winter spirit nodded, grinning at the kid.

"I know!" he said.

"Wait, if you're real, what about the others? The Easter Bunny and the Sandman…" Jamie asked.

"Real. We are all real, Jamie." Jack told the kid, walking forward and sitting on the edge of the bed next to him.

"Then where did they go? What happened to Easter?" Jamie asked, frowning slightly. It wasn't that he didn't believe the magical being in his room, it was just hard to accept that people like that had abandoned their job.

Jack hesitated, thinking back to what happened in his own world. Kids were probably wondering the same thing back there, and it was his fault. His hand went towards the case of teeth in his pocket, the ones he had managed to get from Pitch before he discovered what had happened. He didn't deserve these memories, not after what he had done. "Bunny…got into some trouble." Jack said after a moment, not certain of how Pitch had won in this world. It looked like the Jack Frost here was working with Pitch. The Jack sitting with Jamie could not believe that he would do such a thing, but it was true nonetheless.

Jamie frowned, before sighing and leaning back in his bed. "The boogieman, right? Fear made children stop believing, so I guess that means that he attacked the Easter Bunny, Santa, and all the others?" Jamie asked, looking to Jack for answers.

"Well, sorta. I'm not exactly sure." Jack commented, getting up once more. He got restless sitting in one place for too long, even if he wanted to help the kid. Jaime glanced at the winter spirit, wondering what he meant.

"How can you not be sure? You know them right?" Jamie asked, watching as Jack tapped objects in his room with his staff, frosting them over as he did so.

"Eh, I guess so. I'm not exactly from here, though. I come from another dimension, where there is another version of all of us. Another Pitch, another Bunny…" Jack trailed off, thinking of his own world. "Another you even." he added, grinning back towards Jamie. The kid looked surprised, but excited about the idea. Another world sounded great, like a place he could escape to if things got too bad over here.

"Wait, so you aren't really Jack Frost?" Jamie asked, realizing that if there were two of everyone, there were two Jacks as well.

"Hey, that's not nice. I am Jack Frost, just not the Jack that lives in this world." he explained, shrugging and deciding it was time to stop messing up the kid's room. It had plenty of snow in it already without him making more out of boredom.

Jamie giggled, clearly entertained by this Jack regardless of where he came from. "Well, at least I know they're out there, somewhere. It's better than what the other kids believe right now." Jamie whispered, staring out the window. Jack joined the kid, thinking of the danger this world faced. Things were bleak here, a world where Pitch ruled and children lived in fear. Perhaps he could change that, with a little help. For now, this world needed a Guardian more than ever, and Jack could try and fill that role. Glancing towards Jamie, Jack began to get an idea. This kid would be the start of everything, the beginning of the return of belief in this world. Jack would bring back the Guardians, with his help.

"Say, how would you like to help the Guardians of your world?" Jack offered, grinning at Jamie and swinging his staff over his shoulder.

Jamie glanced at Jack with a confused expression. "Guardians? What's a Guardian?" he asked, frowning slightly.

"Well, a Guardian is someone who watches over the children in the world. North, Bunny, Sandy, and Tooth were all Guardians back home and I'm guessing they are here. They protect every child and they try and preserve different aspects of childhood like dreams and memories." Jack explained. He wondered what he would have protected if he had joined them. He had thought about it for a while, considering North's questions about what his center was, but he was still uncertain.

Thinking about it more, Jack began to focus on what he did all the time. His first meeting with the Guardians, he had told them that he was all about snowballs and fun times. Even as he battled against Pitch, Jack never focused too much on working hard, only on having some fun. Perhaps that was what he protected, his center that would guide his actions. It seemed to fit too well for him for it to be wrong. "Fun, that's it." he mumbled to himself, used to being unseen by others and unable to stop himself from speaking.

"Uh, what?" Jamie asked, confused by Jack's last comment. Jack grinned, not bothering to explain.

"Never mind. Are you with me?" Jack asked, holding his hand out towards Jamie. Jamie looked uncertain, afraid of what would happen but wanting to take a risk. Nothing would change if he stayed here and did nothing. Taking a deep breath, Jamie nodded and reached out, grabbing Jack's cold hand with his own. Together, they would find a way to stop Pitch and bring back the belief in children around the world.
