Volcano? Maybe Jack doesn't want to know. He starts to lead the way towards the edge of the city, but he decides a tiny explanation is in order.

"I used to have a pet dinosaur. Pterodactyl. A- good friend and I, we caught her with chocolate bars. She was the closest thing we had to a guard dog." Jack ponders. "Guess that's one loose end I left behind at home. There's a candy-addicted dinosaur flying around Cardiff, and nobody that she'll answer to." Jack laughs at the mental image.

When they reach the gates to the city, Jack adjusts his grip on his belted sword. "Any idea, specifically, what's out there? Anything that we'd be better off running away from?"
