Jack continued to look up at the Doctor, that wide grin on his face. "Oh I think you'll do."

He dusted himself off a little as he stood, slinging the bag over his back and turning his head to look out to the path and then back to the Doctor beside him.

"Oh now who's changed their tune?" he shook his head, "There's a ridge, it's lower down, there's usually a rope ladder tied down the side."

And on that, he took a step forward and put his hand almost absently (but in truth not at all) to the Doctor's upper arm.

"We'll be fine. About a 5 foot drop from there."
