Revelations from Patch 5.5 (Part 1)

[Kesey]

To borrow a phrase from a series that shall not be named, G'raha is "still in his promotional period." It's easy to forget that Alphinaud and Alisaie had theirs, too, in the leadup to Heavensward and Stormblood respectively. Krile also got hers in the form of the Triad story, but then she basically took over as a less intrusive Minfilia and continues to dwell primarily in side stories.

We don't really know where G'raha will land after 5.55 (or if he'll even still be breathing), but there's a distinct possibility that he's still around the way he is because we need somebody else who remembers Emet-Selch. Their time together in Aumarot could be one big Schrodinger's Gun as far as the writers are concerned.

Krile is a side story? Dude she is literally the one moving the plot forward now. Recruiting for Estinien, pushing the Sharlayan intrigue, and tossing out the idea to free Hydaelyn from whatever is stopping her from speaking. That is not side story my friend.

G'raha needs better writing though (his creepy nature aside). At this juncture, because he's seen the dark timeline, can be around to say these final days are just as bad/worse then what the dark timeline had and maybe say hey I have the Allagen blood that will let us work the spaceship to go to the moon. In the mean time he'll make googly eyes. Even if he's an anime trope, the writing could be way better.
