I spend a lot of time learning the history of the Machina and how Egil changed from a kind, gentle soul to someone bent on destroying all life on the Bionis. Sharla relives a flashback moment with Gadolt, which makes me (and hopefully her too) wonder what she saw in this guy, especially compared to Reyn.
As if the foreshadowing weren't obvious enough, we wind up facing the Jade Face and he reveals himself to be Gadolt, now featuring a Kano laser eye.
also I gotta say navigating Mechonis Field was a bit annoying because it was hard to tell where stuff was because they would show up on the same floor on the map but they would be at different levels, so it took some time to figure out where you were supposed to actually go
