Suddenly, the entire room shook, lights turning themselves off and alarms blaring all around them.

"Chan, where is the power, tho?" Chantho asked desperatly. Nina and the Doctor shared a worried look before they decided to take action.

"Radiation is rising!" Nina yelled, running to the pannel. The Doctor nodded and ran to her.

"We've lost control!" Jack told them. Nina fel a wave of panic go through her body. That poor boy was still inside that chamber, and they could no longer control the radiation he was being blasted with.

"The chamber is going to flood!" Yana also realized.

"Nina!" The Doctor yelled from the other side of the room.

"Busy!" She called back. She was trying her best to override the automatic controls to be able to level the radiation manually.

"Jack, override the vents!" He yelled at Jack. He nodded and quickly ran to another control panel. A long and stressfull munite passed and neither of them was able to do what they intended to.

"We can jump start the override!" Jack yelled at them, holding two gigantic cables in his hands. Before the Doctor or Nina could say anything, he pressed the two cables together. Lights sparked all around him as Jack yelled, the cables electrocuting him.

The lights immediatly stopped flickering and the power was restored as Jack's body fell limp to the ground. As Martha ran to Jack's aid, Nina looked back behind her at the monitor. There was no one in the radiation room, only a pile of clothes. Nina sighed.

10.

"I'm so sorry," Yana told them when they all approached Jack. Nina and the Doctor stood behind the other three people crouching around the fallen man.

"The chamber is flooded with radiation, yes?" The Doctor asked Yana. Nina immeidalty got the same idea he was having. The radiation in the room was going to kill anyone who stood in there for too long.

"Without the couplings, the engines will never start," Yana told them as Martha started mouth-to-mouth on Jack. "It was all for nothing!" Yana yelled in frustration.

"I don't know," the Doctor mumbled. Nina reached down and grabbed Martha's arm.

"Martha, leave him," she said. Martha scoffed, but Nina still pulled her up gently.

"You've got to let me try," she whinned.

"Come on." Nina said as Martha tried to reach Jack once more. "Come on, just listen to me." Martha pouted, but complied. "Now leave him alone." Nina walked her a bit further from him.

"It strikes me, Professor, you've got a room a man can't enter without dying," the Doctor said, trying to sound smart. "Is that correct?"

"Uh, yes," professor Yana said. Nina rolled her eyes at the Doctor.

"Well.." Jack suddenly gasped out loud. Everyone stared at him in either surprise or disbelief, in Martha's case. The Doctor took off his glasses smugly. "I think I've got just the man."

"Was someone kissing me?" Jack asked, still out of breath. Martha let out a laugh that almost deafened Nina's ears as Nina playfully slapped the Doctor's arms. He faked being hurt but soon enough grinned widely, making Nina's heart flutter.

"Are we doing this or not?" She asked him.

The three of them ran through the halls of the base, now empty. All of the people previously waiting there were now inside of the rocket.

They arrived in the rocket's control room, where a man, Atillo, was sitting by a desk.

"Lieutenant, get onboard the rocket!" The Doctor yelled out as they entered the room. "I promise you're gonna fly." Behind them, Jack was proceeding to take his clothes off.

"The chamber's flooded!" Atillo shot back. Of course he wouldnt listen to the Doctor. Nina approached him and placed a hand on his shoulder. She hated using her empathy powers, or whatever they were called, but they had no time to lose.

"Trust me, we've got it," she told him. He immediatly looked more calm. "We've found a way of tripping the system. Run, get on that ship!" Atillo listened to her and ran off.

"Wh... What are you taking your clothes off for?" She heard the Doctor's voice asked hesitantly. Nina watched carefully as he took of his button shirt, leaving him only in a white t-shirt and braces.

"I'm going in," Jack reminded him.

"Well by the looks of it, I'd say that stet radiation doesn't affect clothing, only flesh," the Doctor told him.

"Oh, come on, Doctor," Nina told him with a smirk. "Let the man undress in peace," she winked at Jack.

"Yeah," Jack agreed. "If I'm going to die, at least I look good." Nina laughed. She was, though, too busy mesing with the controls to notice the jealous frown upon the Doctor's face. Jack walked to the door, but before he could get in, he turned around and stared at the Doctor. "How long have you known?" The Doctor immediatly knew what he was talking about.

"Ever since I ran away from you," the Doctor admitted with a sigh. Well, this is awkward, Nina thought as she shifted her weight back ans forth between her two feet. "Good luck," he told Jack before he entered the room. Nina was quick to close the door shut behind him.

The Doctor walked to the door's small glass window to watch as Jack dis qhat he had to do.

"Doctor, Nina, are you there?" Martha's voice came in through the speakers.

"We're here," Nina assured her as she sat down on the desk with a little hop. She wasn't even going to bother trying to look through the window, she already knew she was too short. She couldn't wait to regenerate again, and hopefully, into a taller person this time.

Nina felt a sharp pain go through her head and she closed her eyes, reaching for her head with her hands.

She saw the TARDIS. It was locked, locked form the inside. She couldn't see anything inside of it, but she understood what was going on as soon as she heard a scream.

It was a loud, obviously painful scream, and as soon as it began, there was a bright light coming from the windows of the TARDIS.

Regeneration.

Nina was brought back to reality by two strong hands holding her shoulders. She could see his mouth moving frenetically, but his voice was muffled. She looked around and realised that Jack was still inside the chamber. She cringed at the wave of pain that went through her head and closed her eyes, grabbing at her hair. The Doctor pulled her close to him, letting her hear the beating of his hearts. As soon as the sound reached her ears, she flinched and pushed herself away form him.

"What-" she heard him ask in confusion. Nina looked up and saw how hurt he was from having her push him away from her, but she couldn't care about it, not now. "What is it?" The Doctor asked, his voice now clear.

"Well..." she trailed off. Should she even tell him? She had to, hadn't she? She couldn't travel, follow him around everywhere all the while keeping seecrets and lying to him. "Two bad, very bad news, wanna hear them?" The Doctor's face fell as he nodded gravely. "Well, you know the drums I told you I heard?"

"Yeah?"

"Well, I just realized what they were," she said. "Heartbeats." The Doctor frowned. "Two of them, to be exact. Two hearts, four beats. Dun-dun-dun-dun," she recreated the sound. "And going by the fact that I just saw someone regenerating, I'm pretty sure it has some kind of link." The Doctor did a double take.

"I'm sorry, what? Who?" He asked her, his voice no louder than a hiss, but desperation still noticeable.

"Well, you see, that's the second news," she started. "I didn't actually see who it is. I heard a scream, and it was in the TARDIS, but I couldn't see inside. And then just WHOSH!" She explained, making gestured with her hands to explain what she meant. "But something feels wrong." The Doctor nodded, agreeing with her.

Suddenly, Jack walked off the radiation filled room and closed the door behind him, breathing heavily. The Doctor gave Nina a look that said 'we'll speak of this later' and ran to the contols, grabbing a phone and telling Atillo to take off.

Nina walked to some controls, trying to activate the gravity pulse that was supposed to send the rocket flying into space. Before she could do much, Martha came in running, despair written all over her face.

"Martha, what's wrong?" Nina asked her. Martha grabbed Nina's arm and pulled her to a corner next to the Doctor.

"It's the professor," Martha told them, breathing heavily. "He's got this watch, he's got a fob watch that's the same as yours, same writings on it, same everything."

Both Nina and the Doctor froze on the spot. They shared a shared look before the Doctor turned back to Martha.

"Don't be ridiculous," the Doctor warned, his voice dangerously low. Nina grabbed his arm, turning his attention to her.

"It makes perfect sense," she whispered in realisation. The Doctor frowned at her shaking his head.

"Do you realise what you're saying?" He asked his voice slightly rising with each word. "They're dead, they're all dead."

"Shut up and listen," she snapped at him, shutting him up immediately. "He heard it too. That's what I've been hearing ever since we got here. The drums. It was the watch," she said. To Martha who was right beside them, the conversation made absolutely no sense, but to the Doctor it obviosuly did, since he raised his eyebrows.

"So, he's got the same watch," Jack said. He wasn't getting it either. What Nina didn't understand was; why could she hear it. She didn't have super hearing. The Doctor should have heard it too. And why did it basically drian her everytime she heard the drums? It was almost as if the watch was using her DNA instead of the DNA of whatever Timelord the professor could be.

"It's not a watch, it's this thing," the Doctor snapped at Jack. "Turns a Time Lord into a human."

"That means he might be a Time Lord, you two might not be the last ones!" Jack yelled out at them. Suddenly, an alarm started to blaze. Nina ran to Jack's side, helping him level the radiation utilised by the ship.

"But that's briliant, isnt it?" Martha asked after seeing the lack of enthusiasm from both Time Lords.

"Yes, it is. Course it is," the Doctor told her. Nina nodded.

"Depends which one. Brilliant, fantastic, yeah," she agreed.

"What did he say, Martha?" The Doctor asked her a bit too harshly for Nina's taste. "What did he say?"

"He looked at the watch like he could hardly see it. Like that perception filter thing," Martha told them. Nina ran to the two.

"What about now?" Nina asked. "Can he see it now?"

And for the first time since she met her, Martha saw genuine fear in Nina's eyes. And it terrified her.
