Coraine has noticed that Kine seems increasingly ... distracted. He's worried about the bard - worried that this sojourn underground is somehow affecting Kine's mental state (never all that steady, in Coraine's opinion - although the paladin recognizes that he himself has never had much time for anything but the practicalities of battle and the responsibilities of duty). He begins to wonder if it is wise to leave Kine with the prisoners, particularly when one of them is as dangerous as the cleric, but the twin realities of the dangers they face and the dwindling numbers of the fellowship don't allow a lot of room for compromise. Besides, Kine does seem capable of taking care of himself, when he's focused on the moment.
"Are you all right, Kine? You seem distracted. Is there anything I can do to help?"
