Zenos' body comes back because Elidibus possesses it, and the Ascians can reanimate and repair dead bodies; the same thing happened in Endwalker with Fandaniel and Asahi's body. Zenos' body was clinically dead... but the Ascians can fix it, because unlike your resident White Mage the Ascians actually are necromancers of a stripe. This was a story thread in the Stormblood patches, if you remember.

Zenos' soul comes back because his Resonance kicked in. Just like he possessed Shinryu before, he possessed a random Ala Mhigan soldier, and went on a warpath to get his body back from the guy who took it. You might remember this as an ongoing sideplot in Shadowbringers.
Yea it's been awhile since both Stormblood and Shadowbringers for me, but thanks for clearing up that Zenos thing it's been bugging me.
