Whenever I mention Rin, people tend to start talking about Maechen instead.
Yes, I know that Maechen rocks all the socks in the world, and I know he's got a very entertaining way of talking; but what about Rin?
Why does nobody ever mention him?
Personally, I think he's the coolest Al Bhed character in the whole game: I like how he's always completely relaxed, and I also find his voice really nice.
Once I get the airship, I always talk to him a few times just to hear the "May I help you?" and the "Thank you.".
