There was a moment of silence as the group all stared up in horror at the re-awakened factory. The Doctor opened his mouth to say something, but 7 was quicker. She leapt at the Doctor and pointed her spear at his throat.

"7…" 2 took a cautious step towards her, but she ignored him and kept her spear where it was.

"Start talking, human!" 7 demanded, "I want to know…"

"Time Lord," interrupted the Doctor, as he reached up a hand to gently push her spear away from his throat. 7 looked confused.

"What?" she asked.

"Come on! Mad-man with a blue time and space traveling box arrives out of nowhere and isn't even the least bit concerned that he's on another planet? Not really normal human behaviour is it?"

7 raised her brow and lowered her spear slightly.

"You look human," she stated. The Doctor shook his head in a way that was somewhat wistful and almost sad.

"Believe me, I'm not."

7 lowered her spear completely and held it ready by her side.

"Prove it," she demanded. The Doctor leaned towards her, causing 7 to flinch slightly, although she stood her ground.

"Listen," said the Doctor. He then pointed to his chest twice; first on the left side, and then on the right side.7 looked confused and slightly appalled by his suggestion, but 2 took a step forward.

"May I?" 2 asked the Doctor, alight with newfound curiosity. The Doctor nodded, and 2 leant his head near his chest, listening carefully to both the right and the left side. After a moment, 2's optics widened and his face fell into an expression of disbelief. 2 took a step back.

"Incredible," he murmured, looking up at the Doctor in pure wonderment "Absolutely incredible." 5 took a slightly hesitant step towards his mentor.

"2? What is it?" he asked. 2 turned towards him.

"Two hearts," he explained, sounding amazed, "Two fully functional, beating hearts."

5's single optic widened.

"Two…2, are you sure?"

"Is that unusual?" 7 asked.

"Very," 2 replied, turning to face her, "Had I not just been proven otherwise I would have believed such a thing to be almost completely impossible."

"Nothing is impossible," interrupted the Doctor as he absentmindedly wiped any stray dust off his jacket, "Only the things you believe to be unachievable in every possible way of which you could ever imagine…" His voice trailed off as Amy stepped forward and tapped him on the shoulder.

"Sorry to break up the amazement of your newly acquired time lord fanatics, but the TARDIS is still in there," she said, pointing towards the factory.

"Yeah, shouldn't we be actually doing something about that?" asked Rory, "Because the TARDIS is sort of important…"

"But that…machine," interrupted 9, causing everyone's attention to turn to him, "Why did it awaken? What is it going to do?"

"I believe," said 7 as she turned towards 9, her voice ice-cold, "It awoke because you," she jabbed her spear towards him, and 9 took a step back, "put that thing into it!"

"I didn't know that would happen!" 9 exclaimed in his defence. 7 may very well have attacked 9 right then and there, had 2 not come up behind her and put a calming hand on her shoulder.

"Come now, 7. I'm sure the boy meant no harm. He was merely curious, as we all were when we first awoke. You can hardly blame him."

7 sighed and turned to 2, but her anger had clearly dissolved somewhat.

"How can you defend him?" she asked, "You saw what that thing did to the…to the…" 7 paused for a moment as she tried to recall the name of the blue box.

"The TARDIS," the Doctor added helpfully, "And might I suggest that now probably isn't the best time to be arguing." 7 looked briefly up at the Doctor and nodded before turning back to 2.

"That could have been you," she said quietly, but loud enough for everyone to hear clearly. 9 cringed visibly and looked down at the ground; disturbed and ashamed by the knowledge that, had it not been for the timely intervention of the TARDIS, he could have been solely responsible for 2's death. 7 looked over at 9; feeling satisfied that her comment had made its point, before looking back up at the Doctor.

"I know where we can find answers," she said, knocking her skullmet down over her face so that only her optics were visible, "Follow me."
