The underlying reasoning for Kreyu's thoughtful expression is completely lost on Skellig - as is more murmuring from other men who are in the rear of the group, still working to tend to the dogs, horses, and the needs of the camp in general. He cannot understand anything that they are staying, and it is inwardly frustrating to him to be able to hear but not make sense of the words being spoken.

So he keeps quiet, simply nodding and making notes in his mind of what is being said.
