The Doctor, trapped between an annoyed Rose and an even more annoyed TARDIS, was running out of options. He stared at his captor for a full five minutes before saying anything, having cautiously and one-handedly switched off the screwdriver.

Fantastic. In the dark, trapped between an annoyed Rose and an even more annoyed TARDIS.

"Can't we at least have the lights on?" he whined to the roof. "Please?" Nothing. "Women!"

"Are you going to start talking yet?" Rose spun him round and grabbed the back of his collar, steering him warily towards the captain's chair.

"The TARDIS seems to think I have something to tell you. Which I don't."

Wrong answer.

The floor shuddered violently, sending a few rather inconvenient (but probably intentional, thought the Doctor) vibrations through the chair. Rose's face inched closer, still looking him straight in the eye, until their noses were almost touching.

"I said, are you going to start talking. Because I want a shower, I want something to eat, and I want some lights."

"There is nothing to talk about, Rose! I don't know what's gotten into her lately. Ever since…ever since I regenerated, she's been acting weird." Rose rolled her eyes and let go of the Doctor's coat, sighing and turning towards the console. To her surprise, she could see a light flashing on the other side, and went round to investigate. The Doctor followed cautiously, pulling his coat about him as if he was about to be attacked at any moment.

On the far side of the console, a large red light flashed, and Rose could see that it was a button. She grinned mischievously at the Doctor, her hand hovering over it.

"Haven't you learned anything?" She couldn't decide whether he sounded exasperated or scared shitless. "Don't push the…!"

Rose pushed it.

"…button!"

And in the corner behind her, an image flickered into life. Rose recognised it as the Emergency Programme that had played when the Doctor returned her to Earth. She watched it, open-mouthed, trying to hold back the tears that pricked her eyes at the sight of the old Doctor – her Doctor – standing in front of her again.

Only this time, something different happened. He turned to her earlier than he had done before, and smiled – not the slightly sad smile from before, but an all-out manic grin.

"And if you wanna remember me, then you can do one thing. That's all. One thing. Have a good life. Do that for me, Rose. Have a fantastic life. And…" his smile dropped a little and he looked down. Rose reached out, tried to touch him, but her hand passed straight through the hologram.

The Doctor, or rather his image, looked back up again, and the grin was back. "Have a bloody fantastic life. I love you."

And the hologram vanished.

Rose turned to the Doctor behind her, wiping a tear away, shock written all over her face. He didn't look much better; in fact he looked absolutely awful. His face was white and he was definitely scared now. Before she could say anything, there was a noise from the corner, and she turned back. Images flitted across the air; grainy pictures that looked like they'd been recorded on a CCTV camera. All of the Doctor, some with her in too, but in all of them he looked so sad. Their mouths moved but no words came out, until the last scene.

"What happened?"

"Don't you remember?"

"It's like…there was this singing…"

The image flicked out, and slowly, lights came on. Rose turned slowly to face the Doctor, who was by now sat on the floor, arms and legs spread out, looking completely hopeless. Rose walked over and knelt down in front of him, but he ignored her, tilting his head back to look at the ceiling once more.

"It won't work. It wouldn't work!" he shouted. The floor shuddered, the movement growing and growing until Rose felt as though the TARDIS was trying to tear itself apart. She leant over and took the Doctor's face in her hands, forcing him to meet her confused gaze.

"What happened? What happened to me? What did I do?"
