"And we've got a whole country to explore here," he says. "They find us in one city, we'll just go to another. I'm not getting back on another plane unless I really have to."

This last part is said with a little more drama than is necessary because, of course, Crowley would much rather get on a plane than be destroyed by the armies of Heaven and Hell. All the same, he likes the idea of exploring with Aziraphale. Of being out of danger----even if it's only for a little while.

"We could have done this when we retired," he says. "Traveled. I never really thought about it, I liked London too much. But exploring the world as it grows and all that."
