He remembers fragments.

Little pieces and bits, coming together to solve the puzzle.

First, he remembers her face.

Warm brown big eyes you would melt in if you even stole a glance at her.

They changed when her emotions changed, hard steel eyes when she was mad at him. Which happened once. Okay, maybe more than that.

He hated when that happened. He felt like hitting himself. Sometimes he was such an idiot. His genius mind sometimes overthought.

Her laugh was enlightening, he loved her laugh. The beautiful sound filled the TARDIS whenever it was silent.

Then he would smile, or sometimes give a little chuckle.

He remembers her voice, one that could change his mind in one second. She cared for him so much, and yet, he couldn't quite remember her fully.

It annoyed him.

He was supposed to know everything.

When he didn't know something or remember something, he would be curious and happy.

But not now.

He couldn't just stand around trying to piece the jigsaw puzzle together, he couldn't just stay in his blue box forever. He couldn't just mope around, wondering about her. He needed to find her, he needed to see her again.

He scribbled down in his notebook, which was crinkled and crisp from his tears and annoyed attempts to not rip out any of the pages.

He gripped his pencil tightly and wrote out more words.

The sound of the tip hitting the paper relaxed him, it made him feel as if he was doing something to help her.

The notebook shut and he tossed it onto the console of the TARDIS. He gently put his pencil down and sighed, closing his eyes and holding onto a lever.

He had to do something.

The idiot.

The hero.

The predator.

The storm.

But now, he was just some sad man in a blue box. Trying to figure out who she was.

He looked up and at his chalkboard, he still hadn't erased the words off of it.

Run you clever boy

And be a Doctor

He pushed it all aside and pressed a few buttons, spun around and fiddled with the controls on the console.

The machine hummed in response and he rushed towards the door.

He was going to run.

He was going to run to her.

The Doctor smiled and whispered,

"Clara Oswald."
