A/N: Okay, so I rewatched Rise of the Guardians online, and this little story popped into my head. Sorry if the characters seem a little OOC. It's my first time writing these characters and I might make mistakes. Still, hope you guys like it.

Oh, and in my story, Jack dies when he's 16.

Disclaimer: I do not own Young Justice or Rise of the Guardians (same goes for the chapters that follow)

Chapter 1

Skylar pulls the muffler tighter around her neck. She honestly doesn't think it could get worse, even when her body's completely covered, but her neck is freezing right now. And that's not all; she's lost all feeling in her nose and her face. For once, her face feels chilly. If this is how it's gonna be every winter, then she's not ever coming out.

"You cold?"

She looks up and glares at the smirking face of the twenty-three-year-old man. "This is your fault, Dick, you know that?"

He cocks an eyebrow. "Surprisingly, that's not the first time I've heard that." He says.

"Not that hard to believe." She mutters, just loud enough for him to hear. He grins and resumes that idiotic smirk on his face, making her roll her eyes.

"Dick, stop smirking or I'll do it for you." She mutters loud enough for him to head, rubbing her arms.

"Now, now, is that how you repay your brother?" he cheekily asks, shielding himself as she picks up a snowball and throws it at him.

"Seriously, Dick, I hate you." She mumbles as he dusts himself off.

"Love you too." He smiles, wrapping an arm around her shoulders and pulling her against his side. He then leans forward and pulls her beanie a little more down. "You should cover up better, Sky. You don't want Jack Frost nipping at your nose."

"Yeah, right." She laughs, pulling it out of her face. "Keep saying that."

The two siblings walked on towards their favorite coffee shop, unaware that somebody was watching them.

He leaves behind a snowy trail as he quickly flies up the equator, to the North Pole.

Without thinking, the immortal teen bursts through the door into the wide room. "I got your message, guys. Sorry I'm late…"

"Yeah, yeah, 'nuff said." Bunny says. "We've got bigger problems."

"And, what might they be?" he slowly asks.

"Jack, the children need us." Tooth elaborates.

He shrugs. "Of course they need us. Why else would we be Guardians if we didn't guard them?"

"But this time its worse." Tooth says. He can hear the desperation in her voice. "Pitch is back."

"Pitch?" he almost spits out the name. "I thought we sent him off for good last year."

"But he's back, mate." Bunny says.

"And this time, he is going for teenagers." North says, coming up behind Jack and almost scaring the living daylights out of him.

"Teenagers?" Jack coughs.

"Not just any teenagers, mind you." North says, walking to the Globe. "Superheroes."

"Superheroes?" Jack repeats. "Why would Pitch wanna hurt them?" He looks at Sandy, who makes a bunch of images out of sand, very quickly. Shaking his head, Jack turns back to the other three.

"Superheroes protect the world, Jack." Tooth explains softly. "Not just from criminals. Ever heard of the Justice League?"

"Yeah, I was there when it was formed." Jack says.

"Then you must know of their covert ops team." Bunny says. "It consists of their sidekicks, some of the most powerful beings on this earth."

"So he takes them out…" Jack realizes, eyes widening.

"The world will be his to control." North confirms, and Jack can swear he can hear his heart fall to the bottom of his stomach.

"So, what can we do?" Jack asks, shaking it off.

"Actually, it's more what you can do, mate." Bunny says.

"Me?"

"Yes, Manny has offered you a chance to become human for this task." North says. "You will be posing as a normal student to protect these heroes."

Jack gulps. "Um, aren't they all, like, different ages, or something?"

"Most of them, yes," North continues, "but you will meet some wherever you go."

"So, whattaya say?" Bunny asks.

Jack takes a deep breath. "I'm in."

He takes a deep breath as he looks up at the huge building looming up in front of him. Being alive for over 300 years, he knows that this building is the doom of all mankind.

He stares at the name board: Keystone High.

He swings his bag over his shoulders and marches in, smiling at the other students as they pass by. He's actually never felt this way. Even though knowledge of Jack Frost is now global, he can't be seen by everyone. Now, the whole world can see him. Well, his human form at least. Looking in the mirror at his fake home brought back memories. His skin wasn't the pale off-white color he was used to seeing since he fell into that lake. It was now a normal tan, and his hair was back to its original brown. His eyes, however, remained blue. He had been talked into wearing something more than his original blue hoodie and brown pants.

He thinks about all these changes as he walks on. But then stumbles as he feels himself bump into someone.

"What? Oww!"

He looks down and sees his books lying on the floor mixed with someone else's. He looks up to give them a piece of his mind, but sees that it's a girl. He bends down, picking out his books from hers.

"I'm so sorry about that." He says. "I should be more careful."

"No, no, it was my fault." She insists. "I should start seeing where I'm going."

He picks up a book that's hers, sheepishly grins and gives it to her. "This…is yours." He grins. She takes it and stands up.

"Sorry about bumping into you." She says, tucking a strand of black hair behind her ear.

"Doesn't matter." He quickly says. The bell then rings, saving him from further humiliation.

"I should get going. Don't wanna be late." She says, but he's not listening.

"But, I didn't get a chance to…" he turns his head and sees that she's gone. In fact, the whole corridor is almost empty except for him and a few other kids. "…ask your name."

She narrows her eyes as she watches Alex and some other guy talk. Normally, it wouldn't bother her at all, but this is the same guy who bumped into her at the start of school. What if…

She shakes her head, deciding that living with Dick put her in the same paranoia that he had. Waiting a bit longer, she feels her patience start to wane slightly. She gathers up the courage to go over to the two guys. "Hey, Alex." She says cheerfully.

"Hey, Sky, have you met Jack?" Alex asks, turning to her. "He's new."

She locks eyes with the new guy. "Yeah, we've met." She says.

"Wait, you have?" Alex asks, dumbfounded.

"We kind of bumped into each other." Jack shrugs. Then he holds out his hand. "Jack Overland. It's a pleasure to finally meet you properly."

She looks at his hand for the fraction of a second before grasping it and shaking it. "Skylar Grayson. The pleasure's all mine."

"So, Alex here tells me you live with your brother." Jack says, withdrawing his hand.

"Yeah, finally moved in last year." She shoots Alex a look.

Jack opens his mouth to say something else, but then the bell rings, signaling the start of next period. "Tell you what," Alex says, all too cheerful, "Jack, why don't you join us for lunch?"

"Um, are you sure about that?" Jack asks, a little nervously.

"Of course, we're alright with it, aren't we, Skylar?" Alex looks at her.

"Of course we are." She smiles. "You should definitely join us."

She closes the door behind her, walking into the house to see Dick splayed out on the couch, eyes fixed upon the ceiling. It makes her laugh.

"Don't you have work?" she asks, trying to hold in her chuckles.

"Nope," he says, "I took the day off."

"Can you do that?" she asks.

He shrugs, barely moving. "My dad's the boss." They laugh as he sits up.

She drops her bag on the couch, walks over to him and hugs him. "Welcome home, Vrabia." He whispers. She smiles at the nickname. "So, how was school?"

"Not bad, actually." She says, sitting down. "We got a new student."

"Who?"

"This guy called Jack Overland." His eyes slightly widen at that. "What's wrong?"

"You aren't planning on doing anything with this guy, are you?" Dick asks, making her laugh. "Because when Tim was your age, he started dating the new girl at his school on her first day."

"I'm not." She assures him. "He's not that kind of guy anyway. Kind of dorky and idiotic, but okay."

"And how would you know that?"

"He ate lunch with us today."

Dick nods. "Okay, up and at 'em." He says, getting up. "We've got training to do at the Cave."

She takes his hand and he helps her to her feet. "By the way, I am not in the least way like Tim."
