As the Doctor indicated that they should start up again, Jon nudged Scott carefully. He was walking directly behind the guy for a reason and true to form the words "I'm fine" didn't equate with "I'm capable of a route march," but determination went a long way. Hopefully far enough.

"Hey, kid - time to get moving again."

He watched, then waved as Scott came out of his meditative stillness. The blink against sunlight was noticeable and deserved a grin, but the tiredness around those eyes was unmistakable. Hopefully the nap had done him some good though - it had certainly been deep enough for Jon to "borrow" a couple of bottles of water from his bag in any case. What was a little weight between random acquaintances who happened to be in the same plane crash, after all.

Jon handed him the bag with a slight smirk, then pointed towards the smoke. "Onwards and upwards."
