A/N: I totally didn't realize that the term 'frostbite' could refer to the Jack/Tooth pairing, although I have to admit that is kind of a creative, cute term for them. But just to clarify, this fic is definitely NOT of that kind! Although the summary really should have been clear enough XD

Another clarification: This is a developing, EVENTUAL Jamie x Jack. I wanted to try and capture a relationship that slowly grows into something solid and meaningful, hence the main category being Friendship, with the secondary as Romance. So if you were hoping for a quick 'n' dirty get together, sorry, but you won't find that here! :P

Enjoy, and please let me know what you think!

Two – Reunion II

"WHOA!"

For a few seconds, Jack was far too stunned to say anything else. Finally, he came to his senses and ice blue eyes widened as he realized his position.

Taken completely by surprise, he'd offered no resistance as Jamie had pulled him forward and through the window, and as a result had ended up sprawled on top of the other boy. Both limbs and staff were tangled up in an uncomfortable mess, and Jack struggled to free himself from the grinning brunette.

"Wh-what did you do that for?" Jack blurted out as he finally managed to stand. Immediately he winced - the first time speaking to Jamie in years, and that was the best he could come up with? "Uh, you can still see me?" Slightly better he supposed, but not much.

The grin on Jamie's face only got wider and Jack was alarmed to realize that this was the first time in a while he'd seen Jamie look genuinely happy. In fact, he hadn't seen Jamie smile much at all in the past few years.

"I knew it was you!" Jamie crowed, leaping forward to envelop a shocked Jack in a tight hug. The pale haired Guardian couldn't help but note that the last hug he'd gotten from Jamie was drastically different - for one thing, the other boy had barely been able to wrap his arms around his waist, let alone his entire torso.

"What do you mean?" Jack asked, bemused. Despite his confusion, he couldn't help the smile of relief. His fears were completely unfounded, as Jamie could clearly see - and even touch - him.

In answer, the brunette lifted his hand to reveal a small mirror. Jack stared at it for a few seconds, uncomprehending, before realization dawned on him. "You were watching me? Then…you tricked me!"

Jamie laughed out loud. "Well, I didn't think it would actually work, but yep! How else was I going to get you to come close enough?"

Jack shook his head, still feeling as if he hadn't gotten his bearings yet. "So that means…you knew I was out there all this time."

Jamie nodded enthusiastically. "Of course! Don't you think I would have noticed by now? It's not like Sandman would leave behind frosted windows." The teen suddenly frowned. "But then you didn't show up for a whole year. I was afraid you'd stopped visiting me."

Jack felt a smile creeping onto his face. It seemed his first believer had been thinking of him far more than he expected. "Well I guess I didn't have to worry about your spark going out." He murmured softly, mostly to himself.

Jamie shot him a confused look, but seemed to shrug it off. Instead, a slightly petulant look came over the teen's face. "All those times you were outside my window…you couldn't once actually say hello?"

Despite their height differences, Jack felt the urge to ruffle Jamie's hair. So he did, although he had to float a few inches up into the air in order to reach. "Remember what I told you? You don't have to stop believing just because I'm not there."

"Believing in you is different from just wanting to see you." Jamie said bluntly, crossing his arms.

The young Guardian felt his breath hitch in his throat at the words, and a suspicious burning sensation behind his eyes. He had never expected his brief appearance in the boy's life to have had such a lasting effect.

Embarrassed by the sudden mushy feelings welling up within him, Jack pasted on a teasing grin. "You should consider yourself honored. Technically I'm not supposed to be showing myself to you in the first place."

"Why not? Says who?" Jamie whined. Jack couldn't help but laugh – clearly, Jamie had still retained a few of his child-like qualities.

"You're not a kid anymore, remember?"

"So? What's that got to do with-" Jamie suddenly fell silent, and a few seconds later the reason why became apparent. The two boys heard footsteps approaching from outside the room, followed by a woman's voice calling out.

"Jamie? Who are you talking to?"

"Uh, no one mom! Just playing a movie on my computer!" Jamie hollered. He shook his head pleadingly as Jack hopped back up onto the open window, throwing a goodbye salute.

'Wait!' He mouthed. But by then it was too late – the young Guardian had leapt away amidst a flurry of snow.
