Auron looks away from the faded sunset, noticeably silent, but not in the way that he was when he was laughing. There's no detectable trace of humor in this, not even the faintest thread, although if Tidus is looking to find it he might see it just because he wants to. His hands touch the railing, not to steady himself. It never once occurred to him, when disappearing into the city, into the flood of people between the impossibly tall buildings, that he might think he was going away. Maybe it's all too obvious what he is. It's just that Tidus, with his absent parents and his absence of knowledge, can't begin to guess at the truth. They have no sendings in Zanarkand.

Before Tidus has a chance to break the silence, Auron speaks.

"It never occurred to me that you noticed."
