He looked at her. The familiar sound of the TARDIS ripping through time and space.

Stroking the console, reading the old Gallifreyan, he cooed and spoke gently to the machine.
"Come on old girl."

He stood up and walked around. A lonely man he was, yet he told everyone he loved to traveled alone, just him and the beautiful soul of TARDIS. But in all honesty, space and time was vast, and lonely. But he'd rather destroy himself then let others die because of him.

No. He killed his planet, his world. Family and friends, gone because he had a choice to make. Now he was left alone. And with a companion, it reminded him of the risk, the fate of those who love him.

He couldn't do that again. He can't be a heartless monster again... It pains him to do so. With what he did to all his companions the last 10 regenerations, what poor lost soul's life would be ruined by his destruction next?

But he should be stone shouldn't he, he cut off his hearts to destroy a whole planet, his planet. He was old, and worn. He loved again once more, but he knew he couldn't do it again... It was something he couldn't do to whoever it was. He'd never see Rose again, nor Martha or Donna. They're gone, as is everyone else.

He shook his head, and ran his hand along side him, brushing anything that passed him.
"One more adventure?"
He paused and thought of how many times he said that. Was it to really be prepared? Or was he lying to himself, reassuring himself in a way that it could in fact be his last adventure? Like it was known before, he's old and worn. Who knows how much longer he can keep it up.

The TARDIS always took him where he needed to go, and he trusted this last adventure into the hands of the old girl again.
"Let's go, Sexy."
The sound of time tearing, rippling, and unraveling reverberated through his hearts.
He sat back and watched as the TARDIS did her thing.
Her beautiful, wonderful, thing.
