There was not much to do per all. Huntsgirl patrolled the castle to the best of her ability every day, but it was a very big place, much too large for one person to constantly look after. There were many hidden corridors, moving obstacles and annoying distractions all over the place. But as she managed to gain many of the students' respect she thus became informed of many shortcuts within the castle, besides the ones she found out about by herself. She sometimes listened to what the castle's inhabitants had to say; although hardly adding anything of her own, it wasn't quite awful, and sometimes she found out useful information this way.
Another notable event was the one in which a guy once had the audacity to try and flirt, belittling her prowess along the way just because she was of the female gender. Her response was fierce and delivered promptly. Professor McGonagall tried to reprimand her, but even the older woman had to admit that the foolish student had it coming. And after that one incident, none were quite so quick to freely assume things about her anymore. Needless to say, she easily acquired her own enemies due to her loudly proclaimed hatred towards dragons and all other magical creatures – and also because of her cold, unfriendly demeanor.
The American Dragon, on the other hand, had gained very much popularity among the school's population. His demeanor was disarmingly friendly, willing to help, to apologize, to get along with others. He surprised everyone with how charming he could be and his occasional blunders bringing out startled laughter that shattered most of the students' intimidated demeanors. It was a good thing that he kept a reasonable distance from the humans though; otherwise he might've forgotten himself for a moment and slip up. She did not know where he slept, but she assumed he had a private chamber too. He did not always come into the Grand Hall for his meals, tried not to make a habit of hanging out with anyone for too long, and neither to make friends.
She knew how hard it must be for her boyfriend to hide like that. He was a people person, social despite his awkward moments, soaking up the energy from the people he surrounded himself with, like a cat lounging under the sun.
She missed his stupid jokes. She missed the way he smiled shyly just for her. How he was quick to come near her and had a face close to heartbroken whenever he couldn't. How his profile showed the slope of his upturned nose in an adorable curve, how he was still shorter than her and wasn't bothered in the slightest when she had to lean down for a kiss, because he could never get enough of them.
It was moments like these that she regretted not taking her dream charm bracelet with her and that she had insisted that he not bring his own either. It would've been too easy, to slink into each other's dreams – melt away their loneliness through this restless sleep, to build a world of their own, escape from their burdens, to have each other more completely than they ever did in real life, thoughts interwoven in a way which seemed way too intimate if she gave it too much thought.
It would've been too easy to slip up if they did. And even if they didn't, the lack of sleep would be their downfall, because one meeting wouldn't be enough and neither one hundred, which they could not afford. So she had to decide not to tempt themselves with that possibility, for each other's sake.
