Admittingly, that is one thing SE does that I really enjoy. While yes, some zombies are in fact normal zombies, they also explore the fact that some of them will retain their humanity after revival. While not from XIV, but from Tactics Advance 2, one of my favorite variances of this concept - the character Frimelda Lotice whom was forcefully turned into a zombie and quite literally hadn't even realized she was dead at first, and so on.

I thus also agree that Hab needs his story fleshed out - and perhaps other zombies as well that we may meet.
