Indeed, egg talking to himself would be better. Otherwise our existential problem isn't clarified just moved up one level of conscience.

One could imagine the concept recurring outward, since time has no meaning. Maybe when egg has lived all the lives he moves to the next level and finds that he was both egg and the "god", teaching himself.

I was expecting that too. Son was okay, but a bit Jesusy. Self would've been more of a head scratcher.
