I know that Sophie's six years younger than Jamie. I adjusted her age.
It was a peaceful winter day in Burgess. School was out for Christmas break, Pitch had been quiet ever since his latest defeat at Halloween, and Jack had dropped by to instigate a snowball fight, or maybe to enlist Sophie and Jamie in his pranking army. He spotted Jamie talking with Cupcake and Sophie playing with her friends nearby what he thought of as 'his' lake, and so with a loud whoop he dove down.
He landed softly behind his friend without a sound, creeping up behind the boy and putting a finger to his lips. Cupcake gave no indication that she had seen him, continuing whatever discussion she was having with Jamie. Jack reached a point just behind the older boy, and with a wink to the girl, he yelled, "Boo!".
Jamie jumped about a foot in the air and stumbled on the landing, thudding down into the snow with a whump. Cupcake began laughing hysterically alongside Jack, Jamie electing to merely glare at the boy as he picked himself up off the ground and dusted the snow off his backside.
"Eighteen and still scare-able! Ah, Bunny's gonna love this!", Jack crowed, laughing even harder at Jamie's attempt at looking stern. The boy eventually broke down into laughter as well.
"Okay, it was a little funny.", he admitted, attempting to stifle his snickers.
"Just a bit.", Jack said with a grin, holding two fingers a pinch apart.
Jamie rolled his eyes and asked, "So, Jacky-boy, what'cha doin' back so soon? I thought you said you had to snow in Newfoundland", and Jack assumed a smug expression.
"Over and done with.", he said proudlly, "Canada's so snowy naturally that I didn't really have to do anything except nudge a few things.".
Jamie nodded in understanding, said quite calmly, "Think fast.", and pelted a snowball at Jack's chest.
The snowball war that ensued would go down in the history of Burgess as the biggest snowball fight ever. It migrated from the park into the forest, back into town, and down almost every street, finally coming to a climactic finale outside of Jamie's house. Almost every kid in the city was involved at one point or another, and quite a few adults as well, joining and leaving as time and schedules would allow. By the end of it everyone was covered in snow, shivering, and thoroughly exhausted.
They loved every second of it.
"Well that was fun. Let's write it down and do it again next weekend.", Jamie suggested as he, Jack, and Sophie (who had joined about ten minutes in) trudged inside. Jack wheezed out a tired laugh and Sophie batted his arm weakly, but both secretly agreed. That had been fun!
"How is it you have so much energy? I'm an immortal spirit and even I'm tired.", Jack confessed as the two kids took of their winter gear. Well…perhaps 'kid' was a bit inappropriate to describe Jamie. The boy was eighteen now; he could legally drive, had to shave every week, could pick Sophie up without any trouble, and was taller than Jack!
"He's an eighteen year old boy. His hormones give him more than enough energy.", Sophie giggled as they wandered into the living room, Jamie turning a deep shade of red and Jack snickering at his expression.
"I bet. He was so hyper as a kid.", Jack reminisced fondly, trying so very hard not to laugh, but his effort was proved wasted.
"No need to bet. Thin walls, loud noises.", Sophie confided in a stage-whisper.
"H-How old are you again?", Jack sputtered through his laughs as Jamie buried his face in his hands, sinking down onto the couch as Sophie smiled innocently.
"Fifteen.", she answered angelically.
"A-and you…", Jack started, but he couldn't get much further as he was laughing too hard. This continued for a few minutes, Jamie moaning about 'sneaky sisters' and 'why', and perhaps 'inappropriate', before Jack got himself under control and asked, with as straight a face as he could manage, "So, any names?".
Jamie tensed immediately, as did Sophie, and ever-so-slowly they turned towards each other. They seemed to have a silent conversation with just their eyes, glancing meaningfully at Jack every so often until, with a resigned sigh of defeat, Jamie stomped upstairs with a, "Tell me how it goes.", thrown behind him.
Jack was immensely confused by this, which didn't last long as Sophie took a deep breath and answered, "Yours.".
"I'm sorry?", he asked, blinking owlishly, and Sophie sighed in aggravation before glaring at him mildly.
"You asked if there were any names. I answered. Yours.", she reiterated sternly, and Jack's eyes widened before he glanced furtively towards the hall stairs Jamie had ascended moments before.
His anxiousness only increased when Sophie offered a gentle, "He really likes you, Jack.".
The snow spirit turned back to her with a helpless look on his face, mind reeling with this new information before he came up with a feeble, "But…I…I can't.".
Sophie's expression morphed into one of anguish, and imagining that look on her brother's face had Jack's gut twisting painfully and his voice clarifying quickly, "I mean, I'm immortal, Soph. I like him too, and I want…whatever it is that would develop between us, but…Whatever time we'd have would be…", but he broke off to bite the inside of his cheek. When he had gotten his emotions under control, he continued, "Not to mention most people can't see me. And to the people who can, it would be weird! I'm stuck at seventeen, while he'd keep aging! And aging comes hand-in-hand with-", and once again he had to stop.
Sophie had adopted a look of understanding at Jack's stilted explanation, and when he stopped she took the opportunity to get a word in edgewise. "He doesn't care about that, Jack. All he cares about is you. And besides, he says that if a regular seventeen-year-old could be turned into the Spirit of Winter, what's stopping him from becoming the Spirit of Fall?", she asked rhetorically, smiling at Jack's shocked yet hopeful look.
"I've been talking with Bunny, and he told me about that crystal that lets Manny send you guys messages.", Sophie continued, a sharp and determined look coming into her eye, "And if he can do it, we can do it. We'll shine a spotlight into it, or maybe just yell at him, but we will find a way to get it through his thick skull that you and Jamie deserve to be happy. And if he doesn't answer, well, North has a pretty big library. There's probably something in there.".
Jack had gotten a look of elation on his face, and it probably would have stayed too, if it weren't for what Sophie said next. "Now, I'm going out with Pippa and Cupcake. If I come back and you don't look suitably disheveled, I'm going to lock you and my brother in a closet for the night.", the girl threatened, smiling smugly at Jack's fire-hydrant-red face before standing up, waving cheerily, and flouncing out the front door.
Seconds later Cupcake came in with Pippa, the two girls giving cheery smiles to the winter spirit as they grasped his arms, lifted him up, carried him upstairs, and catapulted him into Jamie's room. They gave the groaning spirit and dumbfounded mortal another round of waves before swiftly closing the door.
"And they took my staff, too. Conniving little…", Jack mumbled as he got to his feet, glaring at the door before turning to face Jamie. The boy had buried his face into his pillow at the sight of Jack, face burning at the thought of what Sophie had told him and mind racing with the possibilities. He simply laid there for a few moments until he felt the bed shift under the spirit's weight. He turned his head slightly to see Jack merely sitting there, gazing at Jamie as he bit his lip in thought.
"That is one of the most adorable things I've ever seen.", he declared, turning over fully and putting his hands behind his head, "Maybe even more than tiny Bunny.". Jack laughed at the absurdity of the sentence, shocked when the assumed-awkward conversation was anything but.
"I'm more adorable than the kangaroo any day of the week.", he said arrogantly, crossing his arms and smirking down at the brunette.
Jamie snickered and sat up, muttering, "You got that right.", before leaning forward and capturing the shorter boy's lips in a kiss.
Jack was shocked at first, to be sure, but after a few seconds his eyes fluttered closed and he melted against his friend. His arms crept up around the boy's neck as his brain struggled to comprehend the possible consequences of this; he was immortal, Jamie would age, Pitch would probably go after Jamie in an attempt to get to him… However, he found himself caring less and less about what his brain was telling him and more and more about what his heart was telling him.
You love him you idiot, go for it! He doesn't care, Sophie doesn't care, and you shouldn't care! Indecisive, Jack decided to let Jamie decide, so he pulled back with swollen lips and glazed over eyes. It was with supernatural willpower that me managed to give Jamie one chance, one chance, to back out.
"You sure about this? I mean, I am the immortal Spirit of Winter.", he panted, fighting every instinct he had to not dive back into everything that was the boy in front of him.
He lost that battle when Jamie purred, "I guess I'll just have to thaw you out, then.", and attacked his lips again.
