Everything was quiet. Martha had just left. The Doctor would miss her. At the moment, he was kicking himself for how he treated her. He should have noticed her more, treat her as a friend and companion not a mere passenger.
But in his two hearts, he deeply missed his first companion. Rose. She was beautiful, smart, and feisty at times. Best of all, she always knew what to say, and did what she knew was right. The TARDIS felt empty without her. But it was his fault she was gone. He could not stop her. Could not save her.
That, he remembered, was one of his reason for keeping his distance from Martha. He was a danger to everyone no matter what good he did. Martha almost died several times, and Rose,... he would never be able to see her again.
He patted the TARDIS machinery, saying, "Just you and me old girl. Where to now? All of time and space..."
The Doctor paused, unable to continue his train of thought. He was so lonely. The curse of the Timelords.
"No more companions. I hate being alone, but I can't have another Rose. I refuse to lose anyone else." he sighed.
The Doctor's screen beeped.
"Hello, what's this?"
Suddenly, the TARDIS lurched, sending the Doctor flying.
"What are you doing?" he cried out.
