The Last Great Time War: part III

The Moment

The Renegade patted the TARDIS console and sighed.
"Goodbye, old girl. It's been fun. Thank you for everything."

The TARDIS moaned in protest, but did not stop the Renegade as he stepped outside the doors for the last time.
It was a dusty, sandy desert as far as the eye could see with a range of dry, barren mountains in the distance. The Renegade trudged for hours under the scorching sun, with sand leaking into his old, cracked boots and a heavy burlap sack slung over his shoulder. It was exhausting and excruciating. Every step brought more pain, every breath was labored. The Renegade wanted nothing more than to curl up on the ground and die, but he owed it to the TARDIS to keep going. She had done so much for him, and she did not deserve to to see what he had to do.

"Combatants of the Last Great Time War of every allegiance, I serve notice on you all. Too long I have stayed my hand, no more. Today, you leave me no choice. Today this War will end. No more, no more..."

After many miles of empty, scorching desert, the Renegade came across an old, deserted barn. By some cruel trick of the fates, it looked just like the one he used to hide in as a child. It couldn't have been the same one, this was a dying planet in a small universe from which the War had long ago moved on.
The Renegade shook his head. Whatever the explanation, he had more important things to worry about.

He stepped inside, latched the door behind him, and set down the burlap sack. Inside it was the Moment, the most powerful and deadly weapon ever created in all of time and space.
He opened the sack. The Moment was a wood and metal cube etched with dire warnings and covered with gears and strange, glowing symbols.
The Renegade realized that he had no idea how to trigger it.

"Now... How do you work," he said as he turned it over, looking for clues. "Why is there never a big red button?"

He nudged a gear and the mechanism started turning. Was that it?
He heard a noise outside and walked to the door.

"Hello? Is somebody there?"
The Renegade reached for a weapon in his bandolier, but it was empty except for the sonic screwdriver. He'd used everything he had. Even the TARDIS's weapons were burned out.

"It's nothing," said a voice from inside. The Renegade spun around. "It's just a wolf," said a young blonde woman sitting on the Moment.

The Renegade didn't care who or what she was. He could have no interference in what he was doing. He grabbed her arm and pulled her to the door.

"Don't sit on that!"

"Why not?"

"Because it's not a chair, it's the most dangerous weapon in the universe," he said as he shoved her out. He turned around, and there she was again!

"Why can't it be both," she said.

"I haven't got time for this, said the Renegade. She stood up, and he tried to grab the Moment.
"Ow," he shouted as his reflexes tore his hands away from the scorching hot cube.

"What's wrong," asked the strange girl.

"The interface is hot!"

"Well I do my best."

Of course! It was her! She was the Moment!

"YOU'RE the interface!"

"Hello," she said as she smiled and waved.

"Enough of this," the Renegade said. "I didn't steal the most powerful weapon in creation just to flirt with it."

The Moment frowned.
"I chose this face and form especially for you! It's from you're future! I think it's called 'Rose Tyler.' Wait no, yes, no... In this form I'm called... Bad Wolf."
