My particular favorite is when Edge recovers conciousness after falling into Uru. The way he panics a bit when those little critters come into view, but Azel speaks up on how not to act rashly in front of the blind buggers. The part of the same scene where Edge frees her from being pinned down by the Hover is nice, too.
I like that scene since its fairly quiet, gives you the first real impression of Azel as a person, and also… just how low on the food chain everybody is. Even the little creatures are deadlier.
