A/N: Hi, this is a random idea that wandered into my brain, I'm not sure where it's going and will probably decide if it continues through reviews. So here goes...

The TARDIS spun through the time space vortex, and within it, the Doctor, Rose and Jack slept.

While Rose and Jack slept peacefully, the Doctor dreamed.

It was raining, and dark. Most people were inside, and those that weren't avoided this area. He instinctively knew which of the dark alleys he should turn down, knew that was where he would find her.

The sound of running feet told him that he had found her. As he turned a corner in the alley he saw what he knew he would, it had been the same for the past three nights. Two girls, fighting the creature with all their strength. They worked as a team, coming at it from different sides, perfectly coordinated, but not speaking. A deadly dance, silent except for the occasional grunt or cry. The dance, as he had always liked to call it, was beautiful and hypnotic. Both using their preferred weapons with skill, the metal of the swords and sai blades flashing in the night.

The Doctor watched as he always did, knowing they couldn't see him. He expected the fight to go as it always did; the girls would beat the creature, and return to where they were living that night. Each night this happened, the Doctor found something different to admire about them. One night it was the co-ordination, the next, strength. Tonight it was their combat skills.

But this night it was different, the creature was stronger, the girls were struggling to beat it. Both of them had taken several blows and the blonde one was limping badly. Although the Doctor felt bad about it, he was glad that it was her and not the dark haired one. He didn't want her to get hurt, even after all these years, she was still precious to him.

A roar from the creature jerked the Doctor out of his thoughts. He looked up to see both girls plunge their weapons into it at the same time. The dark haired girl pulled her sai blades free and was pushed away by the creature, she fell against the wall and lay there stunned. But the other girl was struggling to pull her sword free. Despite his efforts, the Doctor could not see what happened, all he heard was a scream as the creature fell to the ground.

The Doctor was surprised to find his hands shaking, he wanted to go and help, but knew he couldn't. He couldn't even brush the dark hair away from the face of the girl at the side of the alley to see if she was ok. He was relieved when she stirred and sat up. He watched as she picked up her sai blades from where they had fallen, and put one into the sheath at her side. Slowly she got up, wincing at some pain from either the fight or the fall. However, her pain was soon forgotten as she caught sight of her companion, she ran across to where the girl lay face down near the creature. The Doctor felt his hearts jerk as her anguished cry rang out. Looking down he saw why, the body of the girl in her arms was limp, blood from the slash in her throat ran down into her hair and pooled onto the concrete which she lay. The creature was dead, but it had taken her with it.

The sound of sirens had started and was growing louder, heading towards the alley. Someone must have heard the fight. The girl raised her head, the dark hair falling from her face. Carefully she laid her friend's body down; the Doctor could hear her frantic whispering. "I'm sorry; I have to leave you here. I'll kill every last one of them, I swear." Gently she kissed the blonde head, and was gone, thrusting the other sai into its sheath and picking up the discarded sword as she went.

The Doctor followed her as she ran down the twisting streets, avoiding the police that were heading towards the alley. However, he knew that they would only find the outstretched body of the blonde girl. He had seen another creature slinking from the shadows towards the bodies as he left the alley; he knew it would take the body, leaving the police with no clue as to how the girl had met her death.

The Doctor ran after the other girl as she moved through the shadows, not slowing until she came to what appeared to be an abandoned warehouse. He only just managed to slip in behind her as she slammed the door, it may have been a dream, but he didn't fancy trying to walk through a door. She stood for a moment with her back against the door, before sliding to the floor and breaking down as the nights events caught up with her. The Doctor could feel her sobs, so full of pain and fear, tearing into his hearts, into his very soul. He longed to touch her, to hold her. To cradle the shaking girl in his arms and whisper reassuring words to her. But he couldn't, that was the bad thing about these dreams, he wasn't corporeal in them, he couldn't touch anything. That annoyed the hell out of him.

He crouched down in front of her; maybe she might sense the friendly presence, unlikely, but it was worth a try. It almost shocked him that the girl, who had, only a short while ago been wielding a pair of sai blades with deadly intent and results, was now reduced to a child, curled against the wall in the cold warehouse.

He was even more shocked when she raised her head, looked directly into his eyes and spoke two words.

"Help me".
