AN: Several years down the line...

He flicks off the light and puts the book away, smiling, before leaning close and pressing a kiss to his son's forehead. His footfalls are soft as he walks down the hallway. The air cools suddenly, and he turns, a grin slowly stretching across his face as he spots crystals forming on the window.

"Jack." He says softly, the words almost a gasp, suffused with joy.

"You still believe, eh?" Jamie turns around, eyes lighting up at the sight of his old friend. Jack's grinning where he leans against the wall, tiny trails of ice crystal growing into patterns on the surface where his shoulder touches it.

"Yep." Jamie replies, and looks at Jack. "I thought I wouldn't be able to, growing up. But I find myself unable to not believe in you, or the others." He tells him. Jack grins, delighted. Jamie pulls the younger man in for a hug. The last time he hugged Jack, he was half his size. Now it's the other way around. Weird.

"You're old." The immortal teen comments, crossing his arms as he steps back. There's a smirk, but one of humor rather than rancor, and Jamie holds back a laugh, not wanting to wake his son or wife.

"Older, not an old man just yet."

Jack laughs, and Jamie grins.

"Things are okay?" Jack's tone is slightly more serious, probing, and a hint of worry makes Jamie frown.

"Why? Pitch isn't stirring up trouble again, is he?" Jack shakes his head.

"Nah, nuthin' from his field since. Just wanted to check up on you - and your little one." Jack adds, smiling gently in the direction of Jamie's son's closed door.

"Things've been great. Quiet, but in a good way." Jamie tells him. "It's nice to see you again." He says softly, then pauses. "How've things been, being a Guardian?"

Jack chuckles. "Hectic, amazing, exhilarating."

"Sounds like fun."

"What else?"

"Daddy?" A little voice from behind Jamie makes him turn around. The little brown-haired boy rubs sleep from his eyes, which then widen at the sight of Jack. "Jack Frost?!"

Jamie feels a spark of pride and joy when he catches the amazement in Jack's eyes. Even after 30 years, hearing someone recognize him, call him by name, still awes him.

"That's me!"

"Wicked." Max says, beaming. "Can you make ice come to life?" He asks.

"Max, you're supposed to be sleeping, you know that! Say goodbye to Jack, and then back to bed for you." Jamie scolds Max, who pouts.

"I've got to get back to Bunny's Warren to help him with preparations, anyway." Jack says, apologetic. Max runs and hugs him, before he darts off to his room.

"You should visit next winter, if you have time?" Jamie asks hesitantly.

"I'll try. Goodbye, Jamie."

Jamie waves, watching quietly as Jack climbs out of the window, catches the swell of the wind, and flies away, vanishing as if he's never been here. Jamie smiles, and heads to bed. He knows he'll never stop believing in Jack, and that's fine by him.
