[ While Aziraphale doesn't quite expect smiles in times like these, he can see the effort the poor man is putting behind it. That's fine.

The angel has been around mortals for a very long time. He's seen lives, communities, whole peoples disappear, a few he's grieved personally, but it's not the same. He's never had someone who he cared for so deeply that it would have made a big mark. Well, not before Crowley, but he's fortunate enough to have the demon with him. ]

Oh, no need to mention it. I understand that this is all quite personal. If there's anything I can do to help, please don't hesitate to ask.
