"Okay." Sleep and rest were actually things that Kieren needed to do, so he wasn't going to object too strongly to that, even if he was actually as healthy as one could be considered post mortem. "We should take turns resting, though. I don't want to give anyone a chance to catch us by surprise."

Whether because no one was keeping watch, or because only one of them rested up, something Kieren was worried would happen with this guy thinking he was just sick.
