Disclaimer: I don't own Harry Potter, only this story.
Not for the first time, he heard the light patter of feet against the concrete floor leading to his study. He'd been waiting for it, hoping tonight would be the night it would stop. They always meet like this and never made any progress and it was getting old.
Harry Potter sighed leaning his swivel chair back hard, causing an eerie keening noise. He Glanced desperately at the ceiling as he resigned himself to what he had to do and sat waiting for the knock. He fingered the rough hair on his chin and poked at his face like he had often come to doing, thinking he'd never get used to the scar going from over his left eye down to the left corner of his mouth. He sighed again as he closed his eyes as he flopped back on his chair causing it to keen once more when he finally heard the knock.
"Come in Luna," he said quietly while he opened and his eyes and squinted at the door. "You don't need to knock, I mean you should have to knock considering how many charms I have on the door but you seem to be able to get by them no matter what I do!" he finished huffily.
It took several minutes of impatient waiting and silence but the door handle rattled slowly and the door creaked open to reveal his demon of a best friend, otherwise known as Luna Lovegood.
There she stood far to a wake and happy at this hour just smiling at him covered in dark purple footed pajamas with moving blue bunnies all over the place. Just wagging their tails and hopping around with out a care in the world.
Harry would just like to wring their little furry necks and-
"Harry stop starring or I might take it as an invitation." Luna's voice broke through the furry white haze that had encased his mind and he peeked at her face though his fringe.
"Yes, what can I do for you?" He inquired and choose to ignore what she had insinuated.
Harry threw his feet up on the desk next to him, folded his hands in his lap and basked in the last few moments of assured silence in the room.
Luna huffed and looked around her, she had always thought it was so calming and peaceful which was the complete opposite of Harry. It had a great big window opposite the door with a mahogany desk sitting in front of it overlooking the once forest filled rolling hills outside where Harry spent his days working. She Looked to her side and she passed her eyes over the massive dark brown bookcases up against the green grass walls and took in all the books and knick knacks she thought were really pretty. She pulled her thoughts back to Harry though, she had finally found a solution to their problem.
"Harry, I have finally found the answer to how to fix everything," and this got his attention immediately, but she was quick to jump in before he got to excited, "there is however a huge percent chance of this all failing and destroying the entire universe."
He stared contemplating at her trying to sense out her feelings on such a big risk and when he saw the smile she couldn't seem to contain he jumped up, his chair sliding back by the sudden movement and it hit a book shelf and knocked things everywhere.
"Any other downsides?" Harry crowed excitedly and Luna shook her head negatively, "Yes!" he yelled, "We can go back!" and seeing him so happy Luna couldn't help but laugh and join in with his excited screams because the situation is just that great.
Their excited screams echoed out the door through empty halls, past abandoned classrooms and dorms. Bringing Hogwarts the now empty and dead building that once housed throngs of happy leaning children alive once more, at least for the moment.
