Kyouya was at Sefton's side when he saw the other boy falter. Right now, the script called for the concerned utterance of this boy's name. Regrettably, he didn't have it. Instead of faltering, he said, "Are you all right?"

He thought that Haruhi would accuse him of being a kind person again, and he had to keep himself from smiling fondly at the thought.
