"Whatever gets the maximum number of us the most rest."
Kel looks at Sulannus with concern. "Uh, Sulannus, you need to get some sleep as much as the rest of us. You're still pretty badly hurt. But the other night you only needed four hours. So if you slept for four, while I watched, then I could sleep for four while you watched. That way, if Nhalia only needed four hours, she could spell Blunt and in the morning she could ... spell us all. If you get my drift."
He grinned, then subsided, hoping that he hadn't offended the cleric.
