Ari opened her eyes looking around, she had half expected to be back in the Tyler's flat, but she wasn't. She was sitting in a chair in a dark room; she moved to get up, correction she was tied to a chair in a dark room. "Arthur...?" she called no response, alone she was also alone.

"Arthur isn't here, am afraid he's been… disposed of," a voice laughed in the shadows.

"What do you mean?" Ari asked, worried for Arthur.

"Well...you won't know until you join him in death," the voice said, a smirk could be heard in the tone.

Ari shock her head, this was only a dream so they couldn't die. "You're insane just let me go."

"No Ari, I'm not insane, you are!" The voice roared. Suddenly the chair was gone and the room became a coffin, trapping Ari in it with no room to move. "Face it Ari, no one can save you."

Ari gasped, her eyes went wide looking around in darkness but seeing nothing, she pressed on wood lid in front of her but it didn't move, her chest start feeling tight her breathing shallow and an overpowering feeling of dread was setting in. she quickly closed her eyes her hands clenched into fists at her sides. She focused on breathing and remaining calm; she was going to be fine she just had to stay relaxed.

The dark Doctor laughed at Ari's attempts at staying calm. "It's no use, you will die here, buried alive. So deep that not even your precious Arthur can save you." With that the dark Doctor left.

Ari bit her lip trying to ignore him, but seconds seemed to turn to minutes and then to hours, she couldn't tell how long she had been there. Her hands were shaking; her whole body was actually vibrating, her heart pounding her ears.

Sweat beaded on Ari's forehead, the temperature in the little wooden coffin seemed to be getting higher all of a sudden and she felt dizzy. Her breathing was rapid and shallow; she had to get out of there before she lost her mind. She frantically clawed at the panel in front of her; it was soon slick with blood from her shredded fingers. A muffled sob escaped her as tears formed in her eyes and rolled down her cheeks.

Rose began to wake up and realized she was not alone, but she had rather that she had been though the laugh sent ice down her spine.

"Rose, lovely Rose," a male voice spoke. "I was hoping you would be joining me soon."

Rose swallowed looking around but seeing darkness and shadows, "yeah and just who would you be then?"

The figure stepped into the light. "You already know me Rose."

Rose eyes widened, he looked like the new Doctor, he was almost identical except for the cold dead eyes and evil grin also the overwhelming dark feeling he seemed to cause. Rose squeezed her eyes closed shaking her head "no, no you're not him."

"O but I am Rose, don't you remember me? I'm your Doctor," the dark Doctor hissed. The dark Doctor drew close to her face. "And I'm not letting you go you stupid ape."

"No, no you're not," Rose said vehemently, shaking her head again, "the Doctor wouldn't do this to me changed or not."

"But I did. And now no one can save you," the dark Doctor laughed. "The Doctor you knew is dead because of you, I am all that remains."

"He," Rose started then swallowed, "he was in the room with me, he's not died." He can't be.

"Well believe what you want but my dear Rose, I only speak truth," the dark Doctor said, a smile on his face before he left the room.

Tears formed in Rose's eye, he was lying, he had to be. The Doctor couldn't be died, she start to really see now how it was her fault. It was her fault this new Doctor was hurting but he couldn't really be gone too, could he?

The Doctor's body shook with sobs, his brown hair was more unruly than usual and his body seemed to lack very little strength. 10 minutes after the dark Doctor had left the cold holding cell, the door opened again but the figure was a few inches shorter than the dark Doctor.

"It's ok, I will get you out of here," the voice said, twanged with a northern accent.

"You can't be here," the Doctor said in a weak voice.

"Of course I'm not supposed to but you let a bloody ape mess things up with the regeneration process. Now go save Rose and show her how fantastic you are while I get the others free," the man said after releasing the Doctor.
