"That's wise," Dain agrees as he watches Vervain work. He's a little more accustomed now to speaking with someone blind than he was when they first met, and some of the minor behavioural quirks -- such as not looking up when someone speaks suddenly -- pass by without notice. Something that doesn't pass by without notice is how Vervain sorts through the acorns.

Of course, he wouldn't be using sight, but Dain doesn't know enough about the process to guess at what other senses he might be using. Smell? Sound? Vervain doesn't allow enough time for either. He seems to simply know. Curiosity momentarily drowns out misgivings, long enough for Dain to ask without thinking: "How do you tell which ones are good?"

Almost as he's speaking, he realises what the obvious answer might be. Torn between taking the question back with a somewhat blatant 'Never mind' and simply staying silent, Dain sits tensely on his haunches, not quite breathing.
