Cold Nights, Warm Words

'Lost infidelity,
We never said a word
So black and white you see
It's all the lies we've heard'

He sat staring at the walls of their tiny cell. His mind was running through many different possibilities for his escape. It shouldn't have been too difficult after all, he did have the benefit of several lifetimes' worth of experience with these matters, but he kept getting distracted by the warm weight on his lap. It had been a necessity forced on him and his companion by the conditions of their cell.
It was freezing cold, and though he could tolerate it, Sarah Jane wasn't so lucky. She was human after all. So, in order to conserve body heat, she was laid on his lap her head pillowed on his thigh.
The Doctor took a break from his escape plans to look down at his sleeping companion. She looked so innocent in sleep. Over the time that they had been traveling together, she was slowly coming to lose her child-like belief that all people were good at heart. Her face, once so open and friendly, was becoming guarded and wary. He sighed, it was inevitable and it kept her alive longer, but her regretted it nonetheless. But now, all the barriers were down, he could see her calm smile and soft features. It was said on many worlds that the true face is revealed during sleep, and it was of some comfort to know that his influence and that of all the evil people they had encountered had not corrupted her entirely.
Sarah's presence so close to him was stirring thoughts he should really not be having. The warmth he could feel from her small body, and the was she molded to him so easily...
He quelled those thoughts and impulses with a stern reprimand to himself. Sarah chose that moment to shift slightly in her sleep, snuggling closer to him. She was clearly dreaming. The Doctor fixed his gaze firmly on the opposite wall, and turned his attention back to how they were going to escape.
Sarah breathed a deep contented sigh, and mumbled five tiny words that almost made both of his hearts stop. Had he been human, he might have been able to fool himself into believing that he had misheard her.
But he wasn't human, and neither had he misheard her. The Doctor looked down at her sadly. Come tomorrow morning, he would have thought of an escape plan, Sarah would be back to her guarded self, and they would never speak of this night again.
With an infinitely gentle caress, he reached out to brush a strand of hair from her face.
"Sleep well, Sarah Jane." He whispered.

The End
