I know it's petty, and something that's lost to most player's, since it was optional dialogue that never comes up again between quests, but... Arenvald was supposed to get a task directly from Minfilia just before the assault on the Waking Sands that killed all of the old side Scions that we mostly never got to know.

What was that duty?

Well, he was supposed to become the bodyguard for Noraxia, the Sylph that dies defending Minfilia.

When he comes back in Stormblood his optional between quest dialogue is, "For a long time I struggled to make sense of that day at the Waking Sands. Why I survived and Aule and A'auba didn't. Not any more."

The reason he survived is clear... he wasn't doing his job for some reason. He wasn't with Noraxia. I don't hate him for it, but it makes me wonder. Was he out taking a bathroom break or something? Why wasn't he where he was supposed to be?

It makes me feel like he has bad karma coming his way.
