I could be misremembering, but I could've sworn one of the twins (Alphinaud, I think) subtly glanced at Kuplo Kopp while he was talking about how ordinary people can't see moogles. I've always thought it was an early hint that these two Elezen kids on the carriage with you are much more important than you might think at first glance.
