Jack looked at the tree a moment, in thought, remembering. He'd refused to cry that time he broke his wrist, but as soon as the door was shut he'd been in floods of tears. His Mom had come to him and told him it was okay to cry, and then proceeded to tell him off for climbing trees. It was a memory so long ago that it barely felt like his own. Someone else, another life.

"Oh I'll never learn my lesson," Jack said, looking back to the Doctor, squinting slightly in the sun. "Wouldn't want to," he added. "And like you say, we wouldn't."

And Jack was glad they were. As ironic as that seemed considering the previous evening.

"Yeah," he said, sitting back up a little again. He pointed his hand out towards the city ahead. "You see those buildings at the bottom to the left? The first set of windows? Well see the little bit cropping out there? That's my house."
