Toothiana is, above all things, the memory guardian. She oversees the collection of children's teeth and keeps safe their most precious memories. On some nights, nowadays, she even collects them herself. She flits unseen through the window, slips her hand expertly beneath the pillow, and hums a gentle lullaby, careful not to wake a soul. She holds the tooth and smiles as it sparkles in white moonlight, leaves a coin, and feels a sense of warm fulfillment as she moves to the next house. First and foremost, she is the Queen of the Tooth Fairy Armies, and she does her job efficiently and without fail.

But there are other things, other parts of her, too. One such part, very small and pushed to the back of her being, is the part that has a crush on another guardian. It's the part that makes sure she personally oversees the tooth collection in the little town of Burgess, just in case they cross paths. Sometimes it's the part that forces her to remain in the Tooth Palace, sending other fairies to collect the Burgess-children's teeth, just so that she won't accidentally cross paths with Jack Frost. It's the part of her that thinks of his teeth, and smiles, and makes her hummingbird heartbeat quicken whenever she hears his voice–"Hey, Tooth! Busy night?"–and the part that over the course of several years has been growing.

But she ignores it most days, because, first and foremost, she is the memory guardian, and she must collect the teeth.

Jack is, above all things, the guardian of snowballs and funtimes. He shepherds the winter winds, brings the blizzards, and bestows a sparkle of joy on the bitter weather around the world. He doesn't have that many believers, yet, but they are there, and it means the world to him when they tell the other children his story. It's a cold kind of relief to the sting of loneliness–300 years that slowly trickle away when young eyes grow bright with recognition as he flies by. He tells himself–and it's so very true–that even if it were just one, even if it were only Jamie who saw him, who believed–it would be more than enough. He is grateful to have just one, and he is grateful to have just ten, and after many years, he is grateful to have just a thousand, just a million. Just like that, the pain is all but erased. And because he doesn't just have the children, either–he has a family now.

The guardians don't meet often over the years, but when they do, they are family and they greet each other with warm voices and bright smiles. First and foremost, Jack loves the children. Secondly, Jack loves his family. And then there is a very small part, one he doesn't quite understand, that notices the tooth fairy's little crush. That part makes his heart beat a little quicker. She'd hugged him, he remembered, and it was when she'd pulled back that he'd noticed. (Oh. Oh. Oh? A crush? On me?) It was adorable, and he pushed it from his mind, because really, what did he know about girls, and crushes–he just wanted to have fun.

He never teased her, not once, no matter how painfully obvious she was. Because he wasn't sure, and he'd never say, but there may possibly have been another teensy tiny part of Jack, the part that blushed and stammered sometimes (rarely), the part that noticed how she caught the light, the part that noticed how her smile was the slightest bit crooked–this was the part of Jack that maybe possibly... liked her in return. He kept that part carefully hidden over the years, as he found his place in the world, among the guardians, with the children.

Because he wasn't, couldn't be sure. And he was, first and foremost, the guardian of fun.
