Toothless is out for a walk when he hears the sound of a Viking's nervous footfalls. Aimless. Searching? Or walking in circles? The pattern confuses him so much that he sets off to find the source, snuffling along the ground until he catches the Kid's familiar scent. Following it to his source, he looks to the Kid with a visible (if dragonish) frown. Why does he look like that? Why is he holding his weapons? He glances around, looking for the source of the Kid's anxiety.
