Lelouch noticed the prince's eyes drift elsewhere and noticed the birds. He resisted the temptation to snort to himself. That would be rather rude. He didn't like birds much. Perhaps it was the wolf in him but he just didn't like them at all. Either that or it was because of the encounter he had had with the eagle when he was younger.
"They are?" Lelouch asked, turning from his thoughts as he heard the prince speak again. Well taht was news to him. As far as he was concerned his eyes were perfectly normal and so he told the prince so.
"There is nothing special about my eyes," he stated simply.
