"What do we do if we don't go through a hole?" asked Suzy.
"I think we get smashed to bits," said Arthur. "But like Longtayle said, it's mostly holes. And the current must aim for the holes, or get directed through them. We'll be all right."
"What happens if we don't get smashed completely to bits, but just a bit smashed to bits?" asked Suzy after a while. "I mean, so we're still alive but drowning?"
"Suzy, please don't ask me these questions right now," said Arthur, with as much restraint as he could manage.
