Battles are always chaos, even small ones, even when you're out of the worst of it. Ruel and his six-year-old charge are, having taken refuge in the scribe's wagon while the guards fight and Kiraavi throws lightning at the bandits outside; the wagon has rocked a few times, leaving a mess of ink and paper and glass on the floor, but it's well-made; they should be fine as long as they stay put.
This isn't very reassuring to Teevah, though, and when it rocks again and the door swings open, the boy screams and bolts, jerking out of Ruel's loose hold.
Ruel goes after him, of course, giving no thought to what the ink and glass will do to his shoes as he chases the child out of the wagon.
