The Twelfth Doctor reached in his pockets and found a small keychain that had a light that could help him see in the dark. The keychain was a small lighthouse with a light emitting from the top. It had been something given to him but a little girl on his last adventure with Clara. He had hoped Clara was doing okay. He could only guess where she had ended up with his past self.
The Doctor then took the keychain and shined it in front of himself. He saw a staircase just a few feet away and decided to take that route to see if he couldn't find Rose. The sooner the two of them got off this ship, the better. Then there was just the matter of trying to find his former self. The thing was, too, that he couldn't just search his time stream. An anomaly had been created and the two TARDIS' had to be merged once again in order to fix it. There were parts of his TARDIS that his former self possessed and vice versa and if left unattended for too long the two separate anomalies would create two separate explosions that could shatter any and all universes.
Focusing on finding Rose the Doctor reached a door at the top of the staircase only to realize it was locked. The Doctor was at a loss. He didn't have his sonic on him and was even more upset at just how much he relied on it. He pounded against the door hoping against hope that it would open up. Cursing himself for his terrible luck he slumped over. Just when the Doctor was about to give up and search elsewhere the door opened up behind him and he fell backwards but someone had caught him before he would have hit the floor.
Composing himself quickly the Doctor stood up to confront whoever had opened the door. To his surprise it had been Rose. She looked happy to see him which, naturally, made the Doctor happy. Once the two entered the room Rose had been in Rose pressed a button on the wall and the door sealed itself shut.
"How did you know to find me there?" questioned the Doctor.
Rose smiled. She grabbed him by the hand and led him through another door into a room that would give any hardcore geek centuries of happiness. There were dozens of computers, screens, buttons and wires. It was very sophisticated and even amazed the Doctor. "This is amazing," he said.
"The control room that we thought was the control room really wasn't. This room allows access to anywhere on the ship," Rose explained. "I found my way down here after you zapped me into the boiler room."
The Doctor looked to each screen and saw that Rose was right. Every room of the ship could be seen and it was evident that they were truly the only ones on board. He began looking more closely to find the robot replica of his granddaughter. Correctly guessing what the Doctor was looking for she pointed to the bottom right screen.
"What happened to it?" the Doctor asked.
Rose smiled. "This ship is really quite amazing. It possesses the ability to instantaneously release all the oxygen both naturally and on reserve as well as boiling out any life forms on board without damaging the ship." The Doctor looked to Rose with a raised eyebrow and she cleared her throat. "But it also has a feature that allows all pressure to be extracted either in the entire ship or room by room. I cornered that robot into one of the rooms just not that long ago and crushed it. I then saw you make your way up the stairs and went to open the door for you."
"That's…rather impressive," said the Doctor.
"Don't sound so shocked," Rose said.
He smiled. "No, not at all. Just impressed. Now then, I think it's about time we get off this ship once and for all, don't you?" the Doctor asked.
Rose nodded. "You said it." The two then left back the way the Doctor had came to head to the secondary control room where the TARDIS was. It didn't take too long until they reached the TARDIS and were safe inside.
Rose noticed the Doctor still didn't look quite happy. "What's wrong?" she asked.
The Doctor was looking at the readout of where they were. Now that the warship didn't have it's hold on them he could read the coordinates. "We're so far from planet Earth. It just makes no sense why this ship is all the way out here. And I still have no idea whom it belongs to. It can't be any Time Lord from the Time War."
"And why not?" Rose asked.
"It just can't," the Doctor replied. He sighed. "Best head back. We need to find me. The longer my TARDIS travels with bits of my old TARDIS the worst it will be. The entirety of all universes could end if we don't merge back together."
"Right then, let's find you," Rose said. The Doctor couldn't help but smile as he entered in the coordinates for Earth.
"Back to 2015," he said. He stopped and turned to Rose. "Best if you wait in the TARDIS. We will be heading ten years into your future and, well it's kind of complicated but we can't let anyone see you."
"Why not? Have I really aged that much in ten years that I look so different?" Rose questioned. Not wanting to inform Rose of her doomed fate he pulled a lever and the TARDIS set course for London, 2015.
