This is it. The final chapter. Enjoy.

They made a run for it down the hall. All their hearts were thudding in their chests so loudly that they could all hear. River had grabbed her gun on the way out, so she and Maria took up the rear. River kept her gun locked and loaded in case they met any lizards who weren't keen on rushing back to their sleeping chambers.
It wasn't that far a run to the two TARDISes in the room, but River stopped, suddenly remembering something.
"Doctor," she called. 11 acknowledged her and paused as the rest of the companions fled around the corner. "I'm going to get the TARDIS. I heard a guard saying it was in the storage rooms."
11 nodded, and River spun around and ran, apparently knowing where the storage room was. "Maria, come on!" 11 called.
But before Maria could take a step forward, something slammed down, blocking her way. A clear door had crashed down between Maria and the other TARDISes, cutting her off from them.
"Doctor!" Maria shouted. River stopped and turned.
"Maria, what's wrong?"
"There's a door here. It's trapped me."
11 ran to the door and pressed his hands against it. He glanced around it, confused, and then pulled his sonic screwdriver out and scanned it.
"This is a deadlocked door, I can't get it unlocked."
"Probably because of the gas," Maria said.
"Come with me," River told her. Maria nodded, and so did 11.
"Just go to the surface!" 11 told her. "Same time!"
River nodded and understood. She turned and bolted down the corridor. Maria was quick to follow.

9 fumbled with the TARDIS key. It took a second for him to unlock the door, but when he did, Rose, Martha, and Mickey scrambled through the door. 10 opened his TARDIS, and Amy, Rory, Donna, and Sarah Jane hurried in.
"Where's floppy hair?" 9 asked. 10 opened his mouth to answer, but 11 came barreling in.
"Where's Maria?" Sarah Jane asked, peeking her head out the door.
"River went to get my TARDIS, but before Maria could follow, a wall came down. Maria's gone with River." Sarah Jane nodded. "Just go up to the surface, they'll meet us there. GO!"
10 quickly shut the door, and a few seconds later, the TARDIS dematerialized.
"Get in here," 9 snapped at him. 11 made a start for the door when he saw Clara's body lying in the middle of the room. He glanced at her.
"I can't leave her," 11 said.
"Well, hurry up then," 9 said. "The gas will be here any moment!"
11 ran over to Clara's body and pulled her towards the TARDIS. For such a slim girl, she was heavy. "Help me!" 11 shouted.
It was at that moment, when he heard the gas hissing.
"HURRY UP!" 9 cried, starting to sound really nervous. It was at that moment, when there was a bright flash of blue light. 11's eyes shot up and suddenly, he saw a black figure staring down at him.
"I'll get her to the surface," it said in a raspy voice. "GO!"
11 was to shocked to object. He dashed to the TARDIS, and yanked a gawking 9 into it. He slammed the door shut.
"We've gotta go," 11 said.
"What's going on?" Mickey asked. "What's out there?"
"Gas," 11 replied. Rose hurried to the door. She put a hand onto the handle, but 9 slapped it away.
"It's poison out there," he told her. Rose got on her tip toes to look through the tainted TARDIS windows.
"What the hell?" she whispered.
"What is it?" Martha asked.
"Something just flashed blue," Rose replied. She looked at 9. "What the hell is that?"
9's answer was cut off by the sound of the TARDIS groaning.
"We're going to the surface," 11 told her, pulling a few switches on the TARDIS console. "We're all going home!"
It was at that moment that the TARDIS pitched to the side.

River and Maria found their TARDIS with ease. A couple of Silurian guards had rushed by them, but they were too worried about the alarms to make any sort of action about them. River pulled a key off her neck and fit it in the lock. The door swung open right as they heard the hissing of the gas.
"Get in," River told her. Maria didn't hesitate to obey. River hurried in after her and slammed the doors shut. Then she hurried to the console.
Maria followed her, watching in surprise as River flicked switches and pressed buttons.
"You can fly the TARDIS?" River nodded. "I thought only the Doctor could do that?"
"Well, I learned from the best," River said.
"The Doctor taught you?"
"No, he was busy that day." River didn't elaborate, and Maria didn't feel like pressing for details.
River pulled one last switch, and the TARDIS rotter began to go up and down. Maria grinned.
"We're really gonna make it out of this," Maria laughed. That was when the TARDIS threw her to the ground. River cried out in surprise as she fell too. The TARDIS began to shake and shudder.
"You know, it's your fault for saying that," River shouted.
The shuddering only got worse.

On the surface above, a dark figure watched the sky. The sun had started to set, and she could hear police sirens in the distance. She glanced at the unmoving figure next to her.
The body of Clara Oswald lay in the grass. She was dead, but the way she lay made it look like she was only sleeping. A small feeling of sadness welled up in her. The body was just going to stay there until it was found. The killer would never get caught. Clara's family would never know what happened. It was a truly sad story, but there was nothing she could do about it.
She forced herself to looked to the sky, silent in wait. Through the trees, she began to see the stars peek out from behind the moon. It was very beautiful. The universe was out there, waiting for adventure.
She shifted impatiently from foot to foot, biting her lip, waiting for it to come. She had just received Clara Oswald, and he had disappeared into the TARDIS. Of course, her Time Vortex Manipulator sometimes got things wrong, so she probably arrived a little bit too early.
She kept her eyes trained on the sky. Minutes passed. She wasn't sure how many, but she didn't care.
At last, she saw it.
Three blue blurs appeared in the sky, heading towards the ground. Her eyes followed them as they sailed towards the earth. Right before they landed, each of the three blurs shot back into space, disappearing into the starlight. A small smile spread across her lips.
"Oh, Doctor," SEC whispered. "And you thought it was over. It never really is."
SEC glanced back at Clara's body one last time, and began to walk away. Had there been any onlooker watching her, they wouldn't have seen anything except a blue blast of light. And suddenly, the night was silent once more.

Remember when I said, "All good things must come to an end"?
Well, I didn't say it had to be today :D
Yep, there will be a sequel. I should be posting it in about a month. Can you wait that long?
Please review. Tell me what you think! THANK YOU FOR READING COMPANION PAINS!
