Tifa and Leon had woken up some time earlier, and had let their son sleep rather than wake him up. Leon had a lot of work to do, and after taking breakfast in their room, he'd left for the throne room.
Tifa had stayed, working on mending some of her husband's clothes with a castle musician playing a harp for her, and kept an ear out for her son. So she heard him whine back in the bedroom and motioned for the harpist to keep playing while she went in and checked on him.
"Sora?" she said softly. "Sweetheart, are you alright?" That didn't sound real good. "I have breakfast for you, whenever you want it." And by that, she meant that she could order his fresh, hot breakfast whenever he was ready to eat it.
