"We're trapped!" Amy whispered.
"No, we're not!" Martha pointed towards a door further up the hall. "Come on! Sarah Jane, use the lipstick!"
"Oi!" the Doctor hissed as Sarah Jane activated it her sonic. "The screwdriver still works, you know!"
They ignored him as Sarah Jane opened the door, and they all dove through. Luckily, the lights were on inside the room, so when she closed the door again, they weren't in darkness.
The room was empty, except for a couple pieces of equipment and a couple boxes. They were safe—well as safe as they could be on a Dalek ship. Sarah Jane bent over, her hands on her knees to keep her up, and panted very hard. Amy, Martha, and Mickey leaned against the wall for a rest, but the women ended up sinking to the floor to give their legs a break. The Doctor was the only one who wasn't close to passing out. His double hearts gave him more energy, so he was the only one still moving around the room, investigating the equipment around him. He started fumbling with some controls on the side of it.
Amy was the first to get up and walk over to the Doctor.
"What are you doing?" she asked, still panting. After a moment, Sarah Jane walked over to join them.
The Doctor had his sonic out, and was scanning the equipment. After a moment, he growled and stood up quickly.
"It's useless," he grumbled angrily.
"Doctor, what are we going to do?" Martha asked once she regained her breath.
The Doctor didn't answer. His expression said it all.
"So what?" Mickey said. "We're just going to sit here while the Daleks build their Void Ship?"
"Shut it, Ricky," the Doctor snapped.
"My name's Mickey."
"No, it's Ricky."
"I think I'd know my own name—"
"Guys, shut up!" Martha snapped. "You arguing isn't going to help."
There was silence for a moment, before Sarah Jane spoke up. "I have an idea," she announced.
Amy, Martha, Mickey and the Doctor perked up.
"What is it?" Amy asked.
"What if we were to gain access to the weapons in the ship?" Sarah Jane said. "We could put in the ship's coordinates into the computer and blow it up!"
"That's brilliant!" the Doctor exclaimed. He approached her and threw his arms around her. Sarah Jane hugged him back. "It's been a long time, but I've never forgotten you."
Sarah Jane's eyebrows furrowed together. "You said it's been five regenerations since you last saw me. When was the last you saw me?"
"I dropped you back to earth to go help the Timelords," the Doctor replied, pulling away to look at her face. "Why?" he asked. "When was the last you saw me?"
"Er—Unit?" she said, trying to see if the Doctor would remember. He just looked confused. "They faked your death?"
"What?" the Doctor asked, completely surprised.
"Never mind," Sarah Jane waved it off. "Look, we'll figure this out later, but right now, we need to take down the ship." The Doctor nodded, the confusion still on his face.
"We need to know where the controls to the weapons are in order to do that," Amy pointed out. Sarah Jane nodded.
"Which is why I need to make a phone call." She took out her mobile. "But I'm out of range. Just a bit."
"Give me that," the Doctor said, taking the phone from her hands. He took his screwdriver and took the battery out. He did something to it and put it back in. He handed it to Sarah Jane. "Can call anyone, anywhere in space and time now. Go make your phone call."
Sarah Jane thanked him, then pressed the speed dial button and put it to her ear.

Maria's heart thundered hard. "We're trapped!" she whispered. Rose grabbed her hand and squeezed tight.
"Doctor, do something!" Rose cried. Maria saw the Doctor grip Rose's other hand as he looked back and forth between the two Cybermen.
"I'm sorry," he whispered. "There's no way out."
"Delete!"
"Delete!"
They Cybermen's voices echoed in Maria's ears as she looked back and forth between her soon to be killers.
Something occurred to her. They both were aiming at them. Maria's eyes widened.
She sank to the ground and pulled Rose down with her. As Rose was pulled down, the Doctor was too. Jack was the only one still standing.
"Jack!" Rose exclaimed. "Duck!"
Jack didn't react in time.
The Cybermen shot once at the same time. Maria didn't know which one it was, but one of the Cybermen shot twice. One of them hit Jack, and he fell to the ground, dead.
"JACK!" Maria screamed, but her voice was drowned out by the sound of shots whizzing over their heads. Maria tore her eyes away from Jack's lifeless body and glanced at the Cybermen in the control building doorway as the shot hit him. The sparks flew from the Cybermen as it collapsed to the ground. A similar sounding crackle told her the other shot had deactivated the other Cybermen. They were safe.
That was a lucky break. By ducking the Cybermen fired at each other. But Jack…
Maria jumped up and hurried over to Jack's body. She kneeled besides it and put her head to Jack's chest.
"Oh my gosh," she whispered. "He's dead! But he can't be…"
She felt a hand on her shoulder. She looked up and saw the Doctor.
"Maria, we need to get inside. More Cybermen may be on the way." He pulled the pulsar off Jack's hands, pocketed it, and then reached down to Jack's legs. "Help me carry him inside."
"He's dead," Maria exclaimed. "What's the point?"
"Just do it!"
To afraid to disobey, Maria put her hands under Jack's armpit and picked him up. She and the Doctor carried her through the door into a small room filled with equipment. They set him down in a corner.
The Doctor and Rose hurried to the Cyberman body and pulled it into the room. "It's deactivated, but if other Cybermen find it in front of the door, they'll try to come in," he explained to Maria. "The other one is far enough away so that the Cybermen will most likely leave this building alone."
Maria nodded in understanding. It made sense enough.
Then she remembered Jack. "Jack's dead," she murmured.
"No he's not," Rose said. Maria opened her mouth to ask but Rose shook her head. "You'll see."
Then she left a bewildered Maria standing by herself and went over to the Doctor.
"What's the plan?" Rose asked the Doctor.
"I'm going to hack into the system and transmit the pulsar's power to all of the Cybermen—damn it!"
"What?" Maria asked, hurrying over.
"The system's locked with a six letter password," the Doctor said. "I can't get in! Argh!" He smacked the console.
"Jack would know it," Rose murmured.
"Can we guess what the password is?" Maria asked hopefully.
"And base our guess on what?" the Doctor asked. "It's hopeless!" He gripped the side of his head, moving his coat in a way that something that was in his pocket fluttered out. Maria watched as a piece of paper fell from his inside pocket to the floor.
"What's that?" Maria asked.
"What's what?"
"What's that piece of paper that fell out of your coat?" The Doctor looked down and saw it on the floor. He picked it up and unfolded it.
"It's that message from SEC."
Maria thought she must have misheard. "SEC?" she repeated. The Doctor glanced at paper and his eyes widened.
"Kronos," he whispered.
"What was that?" said Rose.
"Kronos!" He handed Rose the paper. "Look!" Maria looked over Rose's shoulder at the paper.

KRONOS

After a moment, Rose whispered. "Oh my gosh. Could this be the password?"
"It's as good a guess as any," the Doctor said, diving to the controls. Maria saw the screen requesting a password put in the letters K-R-O-N-O-S. The screen flashed green, and data appeared.
"We're in," the Doctor said in disbelief. "We're in!"
"Then do the pulsar thing!"
The Doctor pulled the pulsar out of his pocket and connected it to the computer with his sonic screwdriver. After a moment, his face fell.
"Damn it," he whispered again.
"What is it this time?" Maria asked. The Doctor chewed on his lip as the fumbled with the pulsar.
"The signal's too weak," he murmured quickly. "Even with the sonic, it isn't enough to boost the signal."
Maria grinned. "I can help with that," she told them. The Doctor's head shot up. She went on. "I need to make a phone call though."
"Use this," Rose said, pulling out her phone. "The Doctor upgraded it. It can call anyone, anywhere, any time in the universe."
Maria's eyes widened as she took the mobile, but she decided to ask later. She put in the number, and put the phone to her ear.

After a few minutes of walking, the tunnel had gotten so narrow that they were forced to walk in a single file line. Clara lead the way with the torch. The Doctor was behind her, and River was behind him. Donna was in front of Rory, who took up the rear. It was quite cramped, and Donna was getting ready to start complaining. They stopped before she could open her mouth though.
"What is it?" Rory called up to the front.
"I think it's an exit," Clara called back. "Doctor, take a look at it."
There was a bit of complaining from Clara as the Doctor pushed past her and took the torch. Donna saw a bit of the light shining on a rather large crack in the wall, but it was kind of hard to see over River's poufy hair.
"I think it's a way out," the Doctor said. "I'm going to go through ahead and see where it leads."
They heard some groaning as the Doctor pushed himself through. After a moment, he came back out.
"There's something blocking it. We might be able to push it out of the way, but I'm going to need help."
"Let me through," River said, pushing past Clara, and then past the Doctor. Clara grumbled as she was nearly thrown into Donna.
"You're not going to have to get past me too, are you?" she asked her. Donna let out a small laugh.
Since Clara was smaller, Donna could see to the front. The Doctor shined the torch onto a crack in the wall, and Donna could just see River's hair inside it as she pushed on what was blocking the door.
"It's heavy," River called. "But I think I've almost got it."
Right after she said that, whatever it was rolled over, letting dim light enter the cave. "Come on," River instructed, and she went through. The Doctor went next, and then Clara went through too.
It was a very tight squeeze, but Donna managed to fit through. When Rory emerged from the crack, Donna turned around and scanned the room.
"Oh crap," the Doctor murmured.
"Where are we?" Donna asked.
"We're in the Cryogenic Chambers…" the Doctor whispered. "This room is full of sleeping Silurians."
