She is humming, softly, and swaying, slightly, as she scribbles in her notebook, just aimless brainstorming that circles back to the same points oftener than not. Either way, she isn't paying much attention to her surroundings, even as the door closes behind her, and almost bumps into a table that wasn't supposed to be there before she looks up.
Souls that lose their bodies in the mortal plane appear at the edge of Heaven with new bodies attached. As of about a minute ago, Heaven can no longer hang onto them, so they get dumped into outer space at the edge of the mortal plane, where they then proceed to die again, rinse and repeat. A sphere a light-year across is very large, and only a handful of people die every second, so the accumulating asteroid field of dead bodies is not very dense yet.
There are two pieces of good news, though. First, the people who went to Heaven before God died got made indestructible, so they're still hanging out in space being confused. And second, in the absence of a Final Judgement, nobody new is going to Hell.
"Ohkay. Well. Good news and bad news. The good news is nobody is going to Hell right now."
"The bad news is that everyone who's died since God is just sort of repeatedly suffocating in outer space."
