Martha had been travelling with the doctor for two months now. For two months they had adventures together, her love for him growing, whilst he always banged on about a girl she'd never met. And who, apparently, would always be better than her. She loved him, but she was starting to realise that he would never love her back.
She walked down a corridor of the TARDIS, looking through all the rooms as she went. It was rather ridiculous how many toilets he seemed to have. And it was also ridiculous that after two months, she still hadn't seen all the rooms on the ship.
Her breath hitched when she came to a door with no sign on it. No gallifreyan patterns around the edge. Just a photograph of three people pinned to the middle of it. She tried to open the door. It didn't open. So she pulled off the picture and headed back for the console room.
---------------------------------------------------------------------------
Martha found the doctor sitting on the jump seat, staring into space. He had done that a lot recently.
"Who are they?" Martha asked, thrusting a photo in front of his face.
He took the picture in his hands and looked at it properly. His gut wrenched as he saw, Jack, a man with big ears and a leather jacket, and a blonde girl all with their arms around eachother, grinning madly into the camera.
Martha's heart broke when she saw his face go soft as he took it in. But he was only staring at the girl in the middle. He stroked the girl's cheek with his thumb, before pulling the photo to his chest.
"Who are they?" She repeated, sitting down next to him, putting her arm around him.
He sighed before he spoke.
"The devilishly good looking one on the right is Jack Harkness, 51st Century Casanova, the one on the left in the leather jacket... well that used to be me." He saw the look of confusion of Martha's face "Long Story."
"And the girl in the middle?" Martha asked, though she already knew the answer.
"She was... mine. My Rose." His face lit up as he said her name. He honestly looked like a new man for a second. A happier man.
"Why isn't she here now?" Martha whispered. She felt her own tears of bitter envy welling in her eyes.
He put his head in his hands.
"She got taken away from me." He whispered.
He started shaking, she could hear his sobs getting louder and louder. She had never seen him cry before.
"Why can't you try and find her, then?" She asked, rubbing his back.
He shook his head.
"Impossible." He replied, through sobs
"Just because you believe something's not possible, doesn't mean you won't be proved wrong. Take the daleks, you thought it was impossible for them to come back, but-"
"DON'T MENTION THE DALEKS!" He yelled, shaking her arm off his shoulder "IT'S BECAUSE OF THEM I LOST HER!"
Martha gasped.
"I'm sorry." She whispered.
He shook his head.
"No, I am." He sighed, leaning against the controls "I just hope you're right."
Martha nodded and walked back down the corridor. Tears welled in her eyes as she came to a sudden realisation.
Well... it wasn't that sudden.
She had no chance with him.
She wasn't Rose.
