Zenos is... [big fat spoily]

They really shouldn't bring him back, he was a really interesting/annoying character that should have died in Stormblood and his plot pretty much went nowhere. He was basically an attempt to be the "Blue/Gary" to your "Red/Ash", with the same kind of "I'm better then everyone" obnoxious personality, while channelling the edge and looks of Sephiroth without the mummy issues. He is better off dead and buried at this point.

I can just agree with you and yeh it was a relief to walk away from the final battle because it felt like i was putting an end to a chapter., this was the final and that was it... but yas nothing is certain i guess..i can only hope we won't see this character again
