Jack sat ack down on the sand and laughed up at the Doctor. "Don't get me wrong, I'm not complaining. I like it. I think you should get a red one though, it'd suit you. And I'm just making a point. You wear that because you want to. Same goes here."

He ran his fingers through the sand beside him, feeling it shift and move. If he closed his eyes he could almost feel young again.

"Hmm?" he asked, looking over to the tree. "No idea," he said. "I left here by the time I was 15. Never was quite the botanist back then. I can tell you though I broke my wrist falling from that tree. See the big one? Wanted to get to the top and kept falling down. Had a pretty bad fall once, ended up with my arm in a davis sling. Two weeks later I was at it again. Made it to the top of course."

A pause. "Its a cretavis tree I think, same family."
