The Middle Distance

a. What first endeared Aziraphale to me was his befuddlement, but what made him so compelling to write is his ambiguity and the things about him that are just a little bit frightening. I think it's the example of the two different accounts of what happened to his sword. Either he lied to Crowley, or he lied to God, or he placed a totally false story to mislead Bible readers. (One hardly flattering to himself.) The only thing I'm pretty sure of is that he told Crowley the truth.
b. Courage. He can dither for centuries, but once he knows what he thinks is right to do, he will do it.
c. Rationalization and denial.
d. I have more of a difficulty-variant with him than with Crowley. When something demands to be written from Aziraphale's point of view, it usually comes fairly naturally. But when it doesn't, I have to spend a lot longer sort of working my way in.
e. I'm not sure that I ever have. But I think the closest I've got is probably in The Phoenix and the Turtle, and it's possibly in his actions and what he says at the respective deaths of Bruno and Dee, where I got to write him actually being an angel, with all its baggage and its conflicts.
f. See answer re: Crowley. :D
