Jack bounded forward towards the door and let out a small laugh, "Oh of course not," he said, "I'd hate to ruin that. Just at least let it be somewhere warm?"

He smiled and nodded to the door, looking at it then discreetly to the Doctor. He worried about him, and though he himself wore now a smile and held a spring in his step, there was concern beneath it. He was good at wearing different faces. The Doctor was too, they had both perfected it. He just hoped he wasn't doing that now.

But maybe this would do them good. This place beyond the door, wherever that was.

He pressed his hand to the door beside the Doctor, opened it, and stepped out. Out into the sand dunes outside.

And he knew it.
