For a moment, Zuko thought of his great-grandfathers and how Roku's natural talents, his abiltiy to ease right into new skills and abilities, must have pissed Sozin off a great deal. He'd read the Fire Lord's memoirs, but there hadn't been a mention of that in there anywhere. Perhaps it was that shining pride that seemed to have been passed down from him through Azulon, Ozai, and finally to himself and Azula that prevented him from doing so. He didn't want anyone to know that the Fire Lord was out-skilled by the Avatar, even thought that was the way things were supposed to be.
"Maybe I'm not Zuko anymore," he said, the words falling out of his mouth before he had time to catch them.
