Sora knew that his brother and sisters "treatment" at the castle was going to be hard for Corin to deal with. He had to understand that in Balamb they were servants, their class was below common, and they were legally owned by the royal family. Even the crown Prince couldn't do much about it, but he wasn't looking forward to Corin's comments or disapproval. He was hoping that the ladies and everyone at the keep would help change his parents attitude toward Riku instead. Besides! Corin had JUST met them! "Family" or not, Sora had known Riku longer AND he was his fiance!
Okay, he wasn't going to think about this right now. "He is excited to see you both as well, he has been missing you." He was healthy and happy, yes. "He is well. We will be there soon."
