"Doctor, your suit, you'll be cold," Jack protested, but his body didn't want to listen to his brain, and he leaned himself back against the fabric, glancing his eyes up at the ceiling of the cave chiselled into the stone.

"A bit," he admitted quietly, "I'm not sure I've got much in the way of toes yet." He sighed and glanced down at the Doctor's coat over him, smiling a little softly.

"It should hurt more than this though," he mused to himself, frowning slightly confused. "What did you do?"

And then, quite separate to his question, he added sadly, "I'll have no shoes now. I hate walking without shoes."
