"Sure," John says, in an airy sort of way that commits to nothing. He needs to teach Ianto some unarmed self-defence, really. He needs to get both of them proper guns.

The night passes quietly, and once Ianto has been asleep seven or so hours John finally nudges him awake so he can sleep a couple. It's not exactly an even split, but Ianto needs the sleep more than he does. He passes Ianto his scanner, tells him to try and keep it shielded so the glow doesn't draw any attention and to wake him if anything shows up on it.

Not that John is a heavy sleeper. He wraps himself up and drifts for a few hours, blinking awake at one point as a light shower of rain hits the leaves woven into the shelter, then again properly as the light begins to fade up. Not that the lack of sleep seems to have done him much harm, he's up quickly and stretching himself out -- checking through his pack and squinting at the sky to judge the weather. It's better if they get going before the midday sun really heats up everything, since they'll probably have to stop at that point so Ianto doesn't collapse.
