Over the years, Jack had gotten to know so many little nooks and crannies of the world. He saw places that shouldn't have existed, met people that couldn't be real, and shared in their secrets.

So many years passed and everyone seemed to forget about Jack Frost but, in isolated pockets of the world, there were people who had the potential to believe.

Scotland was home to one such pocket.

The first time he stumbled upon the run down castle, Jack had been inclined to keep going. They were just ruins, after all. But that was just a glance. A second glance, then a third, and the disrepair fell away. The empty courtyards filled with children, the abandoned hallways roaring with sound. Hogwarts School of Witchcraft and Wizardry. It was a strange name, but a good one.

In hindsight, Jack shouldn't have been surprised. After all, he existed.

He learned everything he could about the culture behind these strange and colorful people. He watched as tyrants rose and fell, governments forming and devolving until the Ministry of Magic reigned supreme, and watched generations pass through the halls of Hogwarts.

Muggleborns were a special thing. From a non-subjective point such as Jack's, it was easy to see that Muggleborns weren't exactly that. Sure, the parents of these children couldn't wield magic, but what about their parents? Grandparents? Somewhere in the line, Jack could find a link and trace it to that smiling and hopeful child buying their first wand.

Lily Marie Evans was one of the rare handful who inherited the gift from an ancestor. She was one of the even more rare few that, upon learning about magic, decided to fully open herself to the idea of everything. Even an old rumor about a mischievous winter spirit.

"Why aren't you in your robes?" were the first words Lily spoke to Jack. He had been lounging in a tree on the grounds, watching the first snow of the winter dancing on its way to the ground, when she stopped at his tree. "And how did you get up there?"

"What?"

After three hundred years, silence had been the norm. There were other spirits Jack could talk to, not to mention the Guardians, but why bother? They were too old, too boring, too... believed in. It hurt to spend time with those that could be seen.

Lily Evans didn't seem too surprised to learn who Jack really was, because who was she to judge? No one else believed but, after years of living under her sister's thumb, Lily liked having something all to herself. If Prat Potter got into a few more dangerous snowball fights on the way, it wasn't really her concern.

There were a few snags with no one else believing in Jack Frost, though. If the prim and proper Lily Evans started getting in on pranks, people would assume she went off the deep end. If she went out into a snowstorm, her friends went looking for her. If Lily didn't have an official maid of honor because she wanted to torment Jack with the duties entailed, feelings were hurt. All in all though, they had a strong friendship and a happy one. Until it ended.

Jack hadn't been there that Halloween, of course. He had a job to do and the end of October was always a busy time of year. That wouldn't mean he'd ever forgive himself.

No Lily was bad enough. No Lily meant that no one would be able to see him anymore. No Lily meant that, if Harry ever looked at Jack, he would look through him. He would look through him with Lily's eyes.

So he stayed away. The trips to the United Kingdom got shorter and shorter. Hogwarts was all but forgotten as the winter spirit returned home to Burgess. If the wind blew harder and the snow heavier... Well, no one was the wiser.

A/N: For a place in Scotland, Hogwarts was never shown to get a lot of snow and I thought that was a little odd. It's already established headcanon (oxymoronic, I know) for me that Muggleborns are more open or receptive to news ideas simply because they have to be so I thought, why not throw Jack Frost in? Feels followed shortly thereafter.
