Sora had been less than miserable, less and less as he got better. He didn't want to push it, though. Riku had to remind him that there was no war now, he had time to relax, to recover, to rest. He needed to heal well and strong, so that he could be strong in the years to come. Not so his injuries would linger and facilitate an early death.
He knew that he shouldn't have been stubborn and insist he ride his horse all the way home. He should have taken a wagon as his Aunt suggested, that it would be much easier on him. But he didn't want to come home in an undignified manner.
This was really very NOT comfortable though. "Only miserable," he replied, feeling a dull pain with each of Orion's steps that just added to the aching he felt all over. His arm was brought close to his body and Wilbur walked beside him nearly leading his horse for him just in case. "I am only thinking of home, and my room, and seeing Mother and Father, and sleeping in our bed again." All of it was what kept him trudging on right now.
