Rain tapped on the window of the kitchen. A leak in the ceiling dripped into a pan on the floor. The house was still and silent. The door opened and Rory came through, his hair wet and weighed down by a paper bag. He walked into the kitchen and set the bag down. As he unloaded the groceries, a little dog came waddling in, happy to see him.
"Hey Reggie," he said quietly. Reggie followed him around the house. Rory walked upstairs and into his room. He stopped short in the doorway though when he saw Amy lying on the bed, unconscious. He walked forward but the Doctor came out of the closet and stopped him.
"Don't!" he said, "She's not safe!"
"What's wrong with her?" yelled Rory as the Doctor shuffled back into the closet. He did not answer and kept digging through a suitcase. "What are you doing?"
"Trying to find the Molecular Changing Device," said the Doctor throwing clothes at Rory. Reggie barked and jumped on the bed to get to Amy. "Hold him back! He touches her and we all explode!" Rory grabbed the small dog around the waist and hauled him into the hallway, shutting the door behind him. He leaned over the Doctor's shoulder and watched him as he took out a black box and use his sonic screwdriver on it. The box sparked and Amy gasped. Rory ran to her side as she coughed and lay back down. The Doctor waited for Rory to lay the blanket over her and step back.
He led the Doctor down to the kitchen and they sat at the table. Rory made tea as the Doctor twisted the box in his hands.
"So," said Rory as he set down the tea and sat, "What is that?"
"A Molecular Changing Device," said the Doctor, "I changes a certain person's molecular structure into whatever you want, in this case, a bomb and the person being Amy,"
"She'll be alright then?" he asked, sipping his tea, "She's not gonna blow up or, anything?"
"I doubt it," said the Doctor, "But, I don't think this was planted here long ago,"
"You mean it was set like, just today?" asked Rory setting his tea down. The Doctor nodded and drank a mouthful of tea, then spat it back in the mug.
"A MCD can be planted anywhere at any time," explained the Doctor, "It has a range of an entire house about this size, including the back and front yards. It might take years for that person to be touched inside their house, but it will happen. The result, an atomic bomb explosion ranging all the way to the next street over and perhaps farther, depending on where the person is standing. Assuming it happens and she does explode, that would be at least sixty-four people dead,"
"And while we're in assumption," said Rory, "Would you die too? Or could you regenerate or-?"
"Oh no," said the Doctor waving his hand, "I'd be blown to bits, and so would you," Rory stood and cleaned up the tea. He was thinking about what would have happened if the Doctor couldn't have destroyed the black box, or if he hadn't gotten to Reggie in time. The Doctor walked back upstairs and hung out in the guest room while Rory helped Amy. He waited for three minutes then he could not stand waiting and barged into their room.
"Doctor!" exclaimed Amy, who was sitting on the bed with Rory.
"It's only been like four minutes," said Rory.
"I hate being patient!" shouted the Doctor, "Being patient-"
"Is for wimps," said Amy and Rory together, "We know," the Doctor grinned as they stood and followed him down the stairs. He walked outside into the pouring rain and across the yard to the TARDIS. He swung the doors open and stepped inside his glowing beauty. Amy and Rory walked in behind him and shut the doors.
"Where to?" he asked them.
"Anywhere Doctor," said Amy glancing at the picture shelf. The Doctor followed her gaze, but quickly looked down at the dashboard. "How did the dashboard get smashed?" she asked breaking the silence.
"An accident that won't happen again," he said straining to keep his voice level.
"Who's that?" asked Rory, "The blond one in the jacket?" the Doctor looked up at the shelf and saw that Rory was pointing to Rose Song. The Doctor looked back down.
"Just another companion," he said, "Now! Where to, oh where oh where?" Amy laughed and randomly pressed a button.
"Another planet?" said the Doctor, "I like it," the TARDIS started whooshing and shaking. The Doctor, Amy, and Rory went crashing around. The TARDIS stopped and they stood.
"What happened?"
"GET OUT!" shouted the Doctor as he flung himself at the doors, "GET OUT NOW!" Amy and Rory ran out the doors onto a barren landscape of rock. The Doctor followed them. "Don't stop!" he yelled at them. They ran and ran away from the TARDIS, far away. They were at least a mile off with a huge ear splitting, breathtaking boom filled the air. The TARDIS had exploded. The shock wave hit them from behind and they were thrown off their feet. They stood and kept running as the wave of fire burnt towards them. They jumped into a small hole and the explosion waved over their heads. The Doctor was the first to emerge from the hole.
The rock had been burnt to a crisp and the TARDIS was nowhere in sight. He walked to the place where it had stood in the last seconds of its wonderful life. Something gold twinkled in the moonlight and the Doctor picked it up. The glass bottle with Rose's memories in it. The only thing that could have survived was the mind of a Time Lord.
Tears clouded his vision and he closed his eyes. The tears fell to the ground, one by one, slowly making a small puddle. Amy and Rory walked up behind him. He turned and Amy pulled him forward into a tight hug. He cried and cried onto her shoulder until he had nothing left. His TARDIS was gone, his Rose was gone, and he could not go anywhere else in the universe except a barren rock planet. They made a small camp by the boulders and sat in the dark.
"Her name was Rose.."
