Sora changed direction to wander to the cafeteria. He was all bundled in his coat and scarf. It was getting cold, which made him kind of sad, and wish for the warm tropical sun and breeze.
He was a little disheartened by the slight discussion with Roxas, and doubt was starting to creep in on him. He pushed it away best he could, because one thought became another and another and led to places he didn't want to think about. His parents were fine. FINE.
So he stuck his hands deep in his pockets and was chatting with a guy in their little group of business people who had happened to come to lunch while he was waiting for Riku. He didn't mention his parents at all, just tried to stay with positive talk.
