I like the idea that Auron guides Yuna along her path, but allows her to decide whether to stray from the proscribed course that is set out for her. I see him in very much the same way, as someone who encourages original thought and independent action in the characters that surround him, but who doesn't force these things.
I also enjoy the comparisons between Yuna as a child and Yuna as an adult through Auron's eyes.
You pack so much into so few sentences. The sign of a true artist with words.
