I obviously like Crowley more than twice as much as Aziraphale, which actually isn't true.

Maybe using Aziraphale's POV more? Also, Aziraphale's more likely to use Crowley's name than Crowley is to use his. He only calls him "Aziraphale" once or twice in the book, right?

"I" is in my top ten. That should probably worry me...
