Fíadh tenses a bit as the boy approaches, spoon held frozen in her hand, though at this point it's mostly a knee-jerk reaction. She knows he's too kind to mean her any trouble. But she doesn't really know how to respond to his gratitude, also considering she's fairly certain she didn't do anything other than find a lot of dead bodies.

"... Mhm."

Slowly she brings the spoon to her face and continues her meal.
