Corin was trying not to get rather upset with Riku's behavior, and was holding back his temper from scolding him for being so damn selfish! Their parents had finally written back! They had though Riku, and Namine, dead or worse! And to find out they were alive, and now Riku was AVOIDING their letter? How could he be so cruel?
"Yes, Your Majesty," Corin said, trying to smooth out his expression and the furrow between his eyebrows. He didn't want Riku to catch on that he was annoyed with him, because Heaven and Sky knew how THAT would go over. "I was in the middle of sorting through some considerable amount of mail for my fleet when I saw the letter. I had to bring it right away." He still had mail he didn't pass out yet, because he was so excited to bring this present to his little brother.
"Here should be good enough," Riku interjected, gesturing to a room whose door stood open. "I will wait outside."
