"No, but it explains a lot," says Andrew earnestly, convinced Edgar isn't giving the discovery the gravity it deserves. Clearly the boy could not have guessed, and Andrew has enlightened him, and why isn't he leaping up and shouting 'of course!'?

Frowning, he considers the question. Can he get out from under the bush? Well, he got himself under here (though he doesn't remember how), so that must be a sign. Andrew nods and draws his legs under him, breaking contact again as he stands up more quickly than he probably should. He teeters for a moment or two, then totters in Edgar's direction. To his credit, Andrew makes it to the edge of the bush before his unsteady weaving turns into toppling over on his face.
