Great chapter. Loved the Jor-El dialog.
As to the body disappeariong - I was going to ask too (someone did above) where Martha and Jonathan learned that. Maybe you can touch on it some more.
As far as I know there was nothing in the TV series about a Kryptonian's body disappearing when they die.
Nothing too in the comics where Superman has died for "real" in any number of Elseworld tales over the years. In the comic book continuity the sure sign that Superman is dead is when he turns completely green and starts glowing.
But your premise is interesting.
Hope that it is made clear that Lois saved Superman via the sunlight exposure.
