Will never be over how Jonah provided the most functional definition of humanity in the entire show (tied to physicality, mortality, and free will since those three are the things that tend to disappear when an avatar is subsumed into their entity). Not true, since a true definition of humanity is impossible and he knows it (that’s more than can be said for a lot of the “real” humans out there), but almost flawlessly functional to the purposes of the question in the context of avatarhood. He has clearly thought about it a lot and come to his conclusions.
Sorry for barging in but it’s particularly interesting that while he obviously wants to leave humanity behind by achieving immortality and a post-psychical state with the apocalypse, it remains important to him that his will is his own, to the point that in that same episode he repeats it three times.
In the last one he’s talking about jon as much as he’s talking about himself.
That’s the only way he’s trying to preserve his humanity, because it gives him the sense of agency and control that he desperately needs (and don’t we all)
