It's a bit rushed in the plot department, but I am very proud of it, I hope you will enjoy it.
The gentle whrrwhrrrwhhrrr of the tardisseemed distant and lovely to her. Suddenly, her eyes flying open, remembered that sound. She tore off the sheets and ran down the hall to find where it was coming from. Feet making barely a noise, she ran into her backyard. As she padded through the grass, towards the spot where the willow was, she felt her memories awaken. That night, when he came.
She was a little girl then, only six or seven. She awoke to find the fireplace in her living room had been lit. 'Mother wouldn't have lit the fire, she doesn't know how' she thought to herself. And father had been gone for so long; she could barely remember his face anymore. She heard a crash coming from the kitchen. In haste, she pulled her blanket behind her, as she ran to the source of the sound, clutching the fabric close. There he was. Pinned down by something ugly and alien. His hair stuck out at odd angles, his blue trench coat was draping over the table under his back. He appeared to be around thirty, but something told her he was much, much older. Suddenly a woman came up behind the creature that was fighting the man. She struck it with her mothers cast iron pan. She was a beautiful blonde, shoulder length hair, dressed in a casual fashion. The monster shrieked and fell back. The man reached for a device, sort of like a thick pen, with a light at the end of it. The monster was backed against our dining room window, and when the man pointed his pen thing at it, it jumped through the window. The blonde turned to the little girl then.
"Where's my mummy?" the little girl asked. The blonde knelt down to the little girl and spoke quickly, though gently.
"I'm so sorry, we couldn't save her" her eyes filled up with tears. The man turned to her.
"Rose, we have to go." He looked at the little girl, noticing her for the first time. "What's your name?" he asked her.
"Sammy." The little girl said.
"Sammy, I'm the doctor. From now on you'll have to be brave. I'm going to leave, and find the monster that killed your mother. I promise. And when I do, I'm going to come back here, and I'm going to wait under that willow tree. And then you will know its ok." He turned to the blonde, Rose, "we have to go, before we lose him."
"The doctor will be back, he always keeps his promises" Rose said softly to Sammy. "Be strong till then" they looked at her one last time, and ran off, through the window, into the night.
And now he was back. Seventeen now, Sammy had grown up with her grandmother, who had agreed to move in to the house Sammy had lived in, only because it was owned by her until Sammy was eighteen. She ran through the grass, her heart pounding. There it was. The box, and the doctor, just as wild and clever-looking as that first night she had met him. She stopped, about five feet from him.
"I was brave. I was brave for eleven years… I was brave, because you told me to be. And something in your voice told me I was right to be brave. Each and every night, I would come out here, and sit for hours under this willow. Waiting. I waited for you."
He looked her directly in the eyes and slowly said. "We found it. It's okay now."
"You were gone for eleven years, and yet you don't look a day older." She mused, "How is that?"
He slowly lifted his hand, and snapping his fingers. The door to the blue box opened. Warm light poured out of the box, though the inside was out of sight. He stepped inside the box and turned back to her, holding the door wide open.
"Let me show you how"
