William grunts a no-I'm-totally-awake grunt. Because see how awake he is? So awake. That's why it takes him several seconds to formulate a reply...which ends up being a rueful agreement. "Next good spot we see, aye."

So it's not too long before they're laying out their sheepskins again, rolling up again in their cloaks, bedding down. And William's offer to take the first shift of watch duty comes out rather less convincing that he means it to.
