When Bokyung came back, a canteen was resting by his saddle. "That's full, and it's yours." Goodnight was in the habit of carrying more than one; he could get himself another in the next town they passed through, or get Bokyung one of his own and take that one back. Either way, they both needed water, and he didn't want Bokyung feeling obligated to ask him for something every time he needed a drink.
