Lol what if the final boss is Zenos merged with fandaniel instead with hydaelyn or zodiark. And turns out that fandaniel is Zenos's soul fragments.

Jest aside, I'm not too thrilled with the chance that they're going to pay homage for sephiroth with Zenos. Imagine if we deal with human Zenos as 89 trial, then he escape and merge with something, become monster that we fight in final trial. Then for the first time we will get a solo instance after final trial where we fight human Zenos again.

Yeah.. Nope.. I will take anything besides that.
