I like the way Auron and Rikku interact in this. Not in a shippy way, but as somewhat begrudging comrades who have nothing in common except for the sense of duty that has once again brought them together. The game itself tells us very little about their relationship, but I think you've portrayed it in a way realistic to both of their characters.

I also enjoy Rikku's shoutout to Garland in the first line. :)
