For his own part, Aziraphale made very little effort to conceal his own exhaustion and discomfort. Really, the more vulnerable he was thought to be in this particular interaction, the better it would be in the long run, although, to be honest, he wasn't acting even a little bit. His feet felt like lead. He wondered idly how people did this sort of thing for fun, ran marathons and things. It seemed masochistic.

He did end up having to speed up a bit to catch up with the other man, who was walking at a more normal pace. This was a golden opportunity to find out more information about Famine, or whatever he was currently calling himself.

Now if only he could figure out how to approach the issue subtly. Asking "What happened to you after the Apocalypse?" seemed a little bit incautious.
