Zodiark's Codex entry what do we think about it?

[Kranel_San]

Elidibus, having judged his duties unfinished, created a reflection of himself to keep vigil over his allies.[/I]

This is the same guy who calls himself an unsundered.

I'm not sure what becoming a reflection means. Besides making a physical copy of himself as he still hopped out of the pilot seat and was physically near Emet when the sundering happened so that copy was able to hop through the don't get sundered hole.

That was an interesting word choice, and I guess to signal that Elidibus wasn't just a tempered soul released from Zodiark but a primal created by a primal (which we know from Eureka is a thing that happens) imitating the person Themis, but with Themis's soul inside the primal Elidibus, much like Ysayle inside Shiva. It's just that not only did the Shiva -or Queen Gunnhildr as a better parallel- in this case look indistinguishable from Ysayle/Misija, at no point did the primal form dissipate to release the soul inside until that 6.3 post-fight cutscene.

At least that's how everything makes sense to me right now.
