Nam looks between the net and the river, watching a fish swim by just below the surface, blissfully unaware of the fate they narrowly avoided because the dragon is here to see they aren't wiped out entirely, to see that this doesn't just become another dead river. This human hasn't (yet) contributed to that potential future. He almost did and that is not something that Nam will soon forget, but he can look past it since no harm was done in the end. He can look past it for the moment, at least. One wrong word and the dragon could rescind this kindness he's currently showing to the human.

Gaze returning to the human, Nam gestures for the human to hand him the basket he brought. "Your offering. And your word that this will be the last time you'll try to fish from this river. Trust that the consequences will be dire otherwise."
