... it was dark.

It was dark and cold.

There wasn't anything.

He was alone.

But, then… there was something: a light.

Some kind of light shining through and a silhouette that blocked it.

It was a very familiar silhouette.

The silhouette held her hand and reached for him, inviting him to come nearer.

He could see a curved line in that shadowed face.

"Get up, Doctor," Rose said.

The Doctor didn't take her hand. Rose, understanding, put her hands in the back pockets of her jeans as her smile faded, turning around to look at the Doctor's duplicate, who crossed his arms watching the two of them.

"Well, 'Doctor'" the duplicate said making quotation marks at his name. "You better listen to us this time, because you know if you don't the replica Dimension Cannon will tear the whole universe apart, as you know."

The Doctor ignored them, closing his eyes.

"You can stop it now, Adam," the Doctor said, loud enough for them to hear it. "I know you're here and you're trying to play games with my mind."

"Doctor, this isn't part of that guy or thing you're talking about," Rose responded. "This is us, really. It's Rose, it's your Doctor copy…"

"How do I know you're not lying to me…?"

There was a pause. "I can't prove it," she responded firmly. The Doctor laughed and closed his eyes again trying to get all of this away form his mind. "But you've got to listen, Doctor. Our world is getting destroyed, as well as other dimensions and planets because of… I don't know what, but it's destroying everything. We need your help, and we know how you can help us."

"How come you can understand me and I can understand you?" the Doctor asked briskly. "The TARDIS… my TARDIS is gone. She died."

Rose smiled. "You know Jaquolei? He's not dead, Doctor. He was sent here by some guy a couple of days ago. He's alive."

"That's wasn't my question."

"You know that thing he had to translate languages?" the duplicate Doctor asked. "Well, because I'm awesome and the cleverest person there ever was I have discovered how to install it for humans, animals, Time Lords and other different species in the whole universe."

The Doctor couldn't understand all of this though. "But this can't be happening!" he said, placing his hands on his head. "I closed the breach between the parallel world and this world. You can't have… This can't be happening!"

"Remember when Gwen talked to you?" Rose asked crouching down to his level. "That was me. I spoke through her to be able to communicate with you."

The Doctor stopped and then he believed her. Adam couldn't have caught that, could he? Rose gave him a hand and with her help, the Doctor stood up.

"The whole universe is falling apart, Rose," he told her. "And it's my entire fault."

She shook her head. "Nothing's your fault, Doctor. It's what's supposed to happen."

"This isn't supposed to happen."

She closed her eyes smiling with amusement. "You're right, it isn't." She took his hands in hers tightly. "We need your help to save the whole universe."

"Rose," the duplicate Doctor called from behind. "We haven't got much time."

"We need to stop all this from the point of origin, and that's the world you and Gwen are," Rose said.

"But how do I do that? There's nothing I can do…"

"There must be a way to reverse everything…" she said as if suggesting…

The Doctor placed a hand in his coat and found a gadget in its pockets. It was the reversing time object! He had forgotten he had placed it in his pockets. He hadn't even noticed he had even placed it in his pockets. A big smile covered his face, but fell easily and as quickly as it appeared.

"But it's not enough to stop Adam entirely," he said.

And then, Rose's face turned all sober and sad, as she explained to him: "A life must be sacrificed for the sake of a million."

The Doctor looked sober. "I'll have to do it."

"She didn't mean you," echoed the duplicate's voice.

The Doctor frowned. "Adam?"

Rose shook her head. "Gwen Cooper." The Doctor looked all shaken. "She has to do it herself. Remember she is a descendant of Gwyneth, the one who could see through the Rift. Gwen has that same gift deep within and can combine the whole power of the Rift and that thing in your hand and reverse the whole of time to the point everything was normal."

"But I can't let that happen!" the Doctor yelled. "Gwen deserves to live."

"It's the only way," she replied, shrugging in sadness.

"Rose, time's up," the duplicate shouted.

Rose and the duplicate started to fade away into the darkness.

"Good luck, Doctor."

"Wait! You can't just leave me! There must be another way!"

But they were gone leaving him alone in the darkness…
